Superoxygenation of raw wastewater for odor/corrosion control

Abstract A system and method for inhibiting and precluding the buildup and offgas of offensive odors and corrosive sulfuric acid in wastewater in a variety of locations in a sewage system through the use of superoxygenation. The system comprises an oxygenator having an inverse conical section for a downward flow of oxygen gas injected into the sewage stream prior to entering the oxygenator. In one embodiment, the system is inserted directly into the main sewage stream, while in another embodiment, the system is used to treat a sidestream from the main sewage stream. Description FIELD OF THE INVENTION This invention relates to the field of wastewater collection and treatment, and particularly to the prevention of offensive odors and corrosion in sewage systems. BACKGROUND OF THE INVENTION Raw domestic wastewater commonly generates offensive odors, especially at warmer temperatures, in collection systems and primary clarifiers at the wastewater treatment plant, combined sewer...

Hounslow Council issues odour abatement notice in bud to stop Mogden sewage works stench

The owners of Mogden sewage works are being slapped with a legal order to stop unsavoury smells that “blighted” the lives of the site’s neighbours. Hounslow Council agreed to “up the ante” on Thames Water by issuing an odour abatement notice - which would force an obligation on the company to tackle strong stenches smelt by hundreds of neighbouring residents. At a meeting of the council’s executive on Tuesday, Councillor Jonathan Hardy blamed “a whole list of management failures”, including spills, leaks and problems surrounding Mogden’s odour control unit, as reasons for making the order. The decision came less than 24 hours after senior managers from Thames Water promised Vince Cable MP that they were in engaged in urgent engineering works on two separate defects at Mogden, which have caused a bad smell lasting for days. Council leader Peter Thompson, said: “We actually want to work with Thames Water - we have tried in the past and I think it’s time to up the ante a little bi...

Organics Plant Temporary Smell

The Organics Plant in Bromley has been giving off a spicy vinegary odour following a trial mixing the odour free compost produced from kerbside green bin waste and other material brought in from an external source. Living Earth and Christchurch City Council are working to reduce the odour as quickly as possible. Mark Christison, Christchurch City Council City Water and Waste Unit Manager says: "Living Earth are undertaking a number of measures to resolve the odour issue. The Council and Living Earth are very disappointed with the creation of this odour. The contractor will be doing everything possible to rectify the situation as soon as possible". George Fietje, Living Earth General Manager says, "The Organics Plant was specifically designed using state- of- art oven technology to reduce all odours. This temporary odour is very unusual and we're treating it very seriously". "To reduce the odour we placed material with no odour over the piles of compos...

Odour in bay coming from sewer manhole

Former Timaru resident Megan Waghorn is happy to see Caroline Bay has been redeveloped, but she is horrified a sewer manhole is ruining its appeal by creating an intermittent odour. There is a problem hanging around Timaru like a bad smell - and that is just what it is. It appears to be most noticeable in the area just in front of the whale pot at the northern entrance to Caroline Bay. This is not the first time Timaru residents have complained about an odour. A series of articles appeared in The Courier in May last year, in which many Timaru residents spoke of a smell lingering around the business district. The source of the smell was never confirmed. This time the cause is known and there is a clear solution. Timaru District Council district services manager Ashley Harper, of Timaru, said a sewer manhole was causing the intermittent smell. He said the smell had been in the area for about two years, the time it had taken to make the new sewer. "The smell comes and...

Curb Braeside Quarry asphalt plant noise, odour, say neighbours

Member explains residents'fears regarding a temporary asphalt plant in the Braeside Quarry to McNab-Braeside council. john carter "We hope council will take steps to remove this danger from our midst." A delegation of about 15 people living near the Braeside Quarry shared their anger about emissions from the temporary asphalt plant with McNab-Braeside councillors Nov. 10. In a presentation to the township’s planning advisory committee, Mark Popiel, speaking for the residents group FACT-MB, urged council to take action to curb noise and smells coming from the plant. “Stop the abuse,” he said. “Some of your constituents are suffering. We fear for our personal health and safety. “We hope council will take steps to remove this danger from our midst.” At the end of the meeting, which was also attended by representatives of the quarry owners (Miller Paving), several residents asked what council could do about the plant, which they maintain is adversely affecting thei...

Stench fuels call to tackle tip waste BY LAURA LUVARA

PEOPLE living close to the Tullamarine landfill were last week plagued by a foul smell they believe is emanating from the former dump. The latest complaints came as frustrated residents called a public meeting to keep the community informed about what is happening at Tullamarine Landfill Advisory Committee meetings, which have been closed to the general public. The next committee meeting will be held today. Panel members - including representatives from landfill operators Transpacific Industries (TPI) - will address the issue of LNAPL (light non-aqueous phase liquids) on the site. This substance consists of deadly chemicals, including PCBs (polychlorinated biphenyls) and heavy metals. The committee meeting will be followed by a public meeting on November 24. Terminate Tullamarine Toxic Dump Action Group president Kaylene Wilson said she rushed to investigate the smell on Friday after receiving a call from a resident. "I drove straight up to the dump when the resident rang...

Cat Urine Odour Removal or the best way to help your cat

One of the toughest tasks, when you care for a cat, is the Cat Urine Removal clean up job and it is the cat urine odour removal that is perhaps one of the most unpleasant. I have the great fortune of having six children. My older four children have all left home and are all living their own lives in extraordinary ways. They are all wonderful people doing amazing things - but I must tell you these tales another day. We have always had pets - all sorts - we have had a parrot named Charlie, and another green ringed neck parrot named Bolo. Once when we were in living in Florida we even had a tiny little hand reared bird that the kids called "Garuda Peep Peep Tweet Tweet". My older daughter has taken care of several rabbits, a family of ducks, all sorts of mice, rats and of course cats. We have had so many kittens and cats that I cannot remember their names - the kids can though - they remember all of them. Now my oldest daughter has her own family - and a cats - and now...

Theories of Odor and Odor Measurement (Unknown Binding)

Theories of Odor and Odor Measurement (Unknown Binding) objective odor measurement has been developed in terms of a possible theory of olfaction. Starting from accepted ideas concerning the structure and composition of the nerve cell membrane and the composition of the mucus, possible mechanisms of olfaction are advanced. Any odor-carrying substance must make physical contact with the interior part of the nose. Whether the mucous membrane is "punctured" by the odoriferous substance, or absorption by the mucus produces a change in the state of polarization of the membrane and induces firing, is still open to experimental verification. The authors review current theories of olfaction and some physical models of the olfactory apparatus.

Troqueer residents pong misery ends

TROQUEER residents in Dumfries can look forward to the end of more than 20 years of stinking misery as the latest phase of a £10 million project to upgrade a waste water treatment works has been completed. Scottish Water’s investment at the plant will increase the treatment capacity, provide a new sludge treatment system and reduce odours – putting an end to years of misery for locals who had to live with a lingering pong. One resident, Tom Irvine, who campaigned for an upgrade of the ageing plant, said: “There has certainly been a big improvement since the work was carried out. I’ve lived here for more than 50 years and the smell was horrendous at times. “With the amount of money that’s been spent carrying out the work, there’s no reason why we should have to put up with a smell like that again. I really hope it’s gone for good.” The existing odour control system is water-based and can be affected by changes in temperature. The new system will treat odours arising from the new enc...

Anotec fight range of air quality problems

People who invest in a dehumidifier are often able to hold off the respiratory and other health problems brought on by mold exposure. However, this is just one of many indoor air quality problems that can affect the typical home. For example, the Environmental Protection Agency recently announced its latest "changeout" effort, where residents of a specified area are encouraged to trade in their old, less efficient woodstoves in favor of cleaner new models, or alternatives such as natural gas heating systems. So far, the EPA's efforts have resulted in the replacement of about 13,000 old wood stoves, preventing the release of about 250 tons of fine-particle emissions. Such pollution isn't confined to just rural areas that tend to depend more on woodstoves. Any place with heavy traffic and industrial activity can be prone to particulate matter pollution, which can enter a home through open windows and even attached to clothing. With that in mind, an air purifying...

Factory to emit less toxic substance

LOWER PROVIDENCE — Superior Tube has applied for permission to increase the amount of volatile organic compounds it emits from its Germantown Pike plant. However, the substance being emitted remains far less dangerous than the recognized carcinogen the company used previously, according to state regulators. In fact, according to Lynda Rebarchak, spokeswoman for the Pennsylvania Department of Environmental Protection's (DEP) Southeast office in Norristown, the requested increase of nine tons per year is a direct result of the company's decision last year to completely abandon trichloroethylene, or TCE, in its industrial processes. In order to give up on TCE, the company had to spend about $100,000 to change over its equipment and use a different chemical, called n-propyl bromide, or nPB for short, in order to degrease the tubes it manufactures there. Like TCE, nPB is considered a "volatile organic compound," or VOC. But more significantly, nPB is not consider...

Company stink over EPA fine

A BROOKLYN tallow company has received an EPA Victoria fine for offensive odours. Australian Tallow Producers Pty Ltd were fined $5841 for failing to meet EPA licence conditions that prohibit offensive odours from seeping beyond the boundaries of their Geelong Rd premises, following a pollution incident in July this year. The Environmental Protection Authority had received a number of reports from the community about the odour, which came from a meal dryer that caught fire. The EPA said the company agreed to shut the line down until the dryer was fixed. Environmental services director Bruce Dawson said there were many challenges for community and industry co-existing together. “Companies need to be aware of their social and environmental obligations and if there are problems then they need to actively work towards solutions,” Mr Dawson said. Australian Tallow spokesman Craig Palmer said the company was undertaking significant works to improve odour controls at the site. “...

'Worst weekend ever' with smell from Corranure

A Cavan lobby group has welcomed a move by the Environmental Protection Agency (EPA) to issue a review of the licence granted to Oxigen reducing the amount of biodegradable waste that it can accept at the Corranure landfill on the outskirts of Cavan town. Cian Murtagh, the chairman of the Cavan Better Waste Management group told The Anglo-Celt that residents in the vicinity of Corranure had endured "the worst weekend ever" last weekend with the stench from the landfill. He said that both he and members of the committee took countless calls over the weekend and on Monday from "very angry people" living all around the landfill in Drumalee and Ballyhaise. "They were complaining of waking up in the night, children being sick and terrible headaches. It was the worst weekend ever," said Mr. Murtagh. In a statement, the EPA said that Corranure was one of a number of landfills being reviewed by the EPA. As part of the review process, objections can be made to t...

Odour from chicken farm described as 'unbearable'

Despite recent assurances by the Grand Bahama Port Authority that steps are being taken to address the prolonged problem of a foul odour emanating from the local chicken farm, residents say the smell still persists and is unbearable. The GBPA has issued a release noting that it has been in "constant dialogue" with the owners of the farms, and have "impressed upon them the urgency of resolving the foul odours emanating from the poultry operation." According to the GBPA, those discussions have resulted in the farm's owners, in August, beginning the process of implementing a new and more effective waste management system to address the odour issue. "GBPA Environmental inspectors conduct frequent site inspections to monitor the progress being made, as the new waste management system is being implemented," the release read. "During this period, constant efforts are being made to identify where necessary adjustments are needed to further allevia...

Salamanca sewage action

THE days of raw sewage flowing from drains at Hobart's historic Salamanca Place should soon be over. The first stage of a $1.5 million infrastructure upgrade of the area's sewerage system begins on Monday and is expected to be finished in two weeks. The pump station built in 1912 and many of the pipes installed in the 1950s were no longer able to cope with increased volumes, said Southern Water executive manager service delivery Ian Dunbabin. "The work will help to reduce odour problems while also addressing occupational health and safety issues for our employees," he said. The work is the first part of a plan to further upgrade and improve the wastewater services in the Salamanca area. "This will address a number of issues which are contributing to the problems in the area including the infiltration of stormwater into the wastewater system, siphon line difficulties and the poor performance of ageing infrastructure," Mr Dunbabin said. Treasurer M...

Odour specialists to sniff out smell soluton

A SPECIALIST odour firm has been enlisted to solve a sewage dilemma. The local council has been asked to use its expertise to clear the smell caused by the sewage works, which has been described as ‘sickening’. A manager of the nearby Shell petrol station said the smell had caused disruptions for her and the staff. She said: “It can get quite sickening during the summer months. I feel sorry for the staff, because it’s something they can do without. And it’s a really bad lingering smell, which will come through our vents long after it starts to clear outside. I just hope they can do something about it.” The smell has caused concern since the treatment plant opened in 1998 and is hoping anotec can help solve the problem. He said: “They keep resolving it, but it’s one technical hitch after another. The system being used there now is not what was originally proposed.” Another resident said: “It is not a major problem, as it was initially. At times, it was that bad you could sm...

Fruit canning company SPC Ardmona has been fined nearly $6,000 for having smelly effluent ponds at its Kyabram plant.

Eight people complained to the Environment Protection Authority (EPA) about the foul odour during the orange processing season in August. The EPA's regional manager, Jeff Cummins, says one of the ponds was very shallow and contained waste water with a high organic content. "Offensive odour from these sorts of activities can be quite distressing on the local communities and it was really the inability of SPC to manage their treatment system that necessitated the EPA to intervene," he said.

Slow Death by Rubber Duck

Excerpt of the book..... Slow Death by Rubber Duck: The Secret Danger of Everyday Things The truth of the matter is that toxic chemicals are now found at low levels in countless applications, in everything from personal care products and cooking pots and pans to electronics, furniture, clothing, building materials and children's toys. They make their way into our bodies through our food, air and water. From the moment we get up from a good night's sleep under wrinkle resistant sheets (which are treated with the known carcinogen formaldehyde) to the time we go to bed at night after a snack of microwave popcorn (the interior of the bag being coated with an indestructible chemical that builds up in our bodies), pollution surrounds us. Far from escaping it when we shut our front door at night, we've unwittingly welcomed these toxins into our homes in countless ways. In a particularly graphic example, it's been estimated that by the time the average woman grabs her m...

Green Power

The GreenPower label An accredited GreenPower product will always carry the ‘tick’ label. This accreditation label is supported and managed by governments throughout Australia. When you decide to purchase renewable energy make sure you look for the accredited GreenPower ‘tick’ label. These labels tell you the amount of accredited GreenPower your energy retailer is purchasing on your behalf, as a percentage  (10% – 100%) of your household’s electricity consumption. 50% means that your energy supplier purchases renewable energy from accredited GreenPower sources to the amount equal to 50% of your household’s electricity consumption (or that of the average Australian household).
