Odour Management in Water Treatment Facilities

Odours can be produced in water-treatment facilities as a result of various processes, such as the breakdown of organic matter, the release of gases from chemical reactions, and the presence of microorganisms. These odours can be unpleasant for both employees and the surrounding community, and it is important for water-treatment facilities to manage them effectively.

One of the main sources of odours in water-treatment facilities is the breakdown of organic matter. This can occur in the form of decomposition of plant material, such as leaves and grass, as well as the breakdown of human and animal waste. These processes release gases, such as methane and hydrogen sulfide, which can produce unpleasant odours.

Another source of odours in water-treatment facilities is the release of gases from chemical reactions. For example, chlorine is commonly used as a disinfectant in water-treatment facilities, and when it reacts with organic matter, it can release chloramines, which can produce a strong chlorine-like odour. Similarly, the use of other chemicals, such as alum, can also produce odours.

Microorganisms can also be a source of odours in water-treatment facilities. These microorganisms, such as bacteria and fungi, can grow in areas where there is a lot of organic matter, such as in sludge treatment tanks. They can produce gases, such as methane and carbon dioxide, which can create unpleasant odours.

It is important for water-treatment facilities to manage odours effectively to ensure the health and safety of employees and the surrounding community. This can include implementing process control measures, such as maintaining proper pH levels, to reduce the production of odours, as well as using odour-control technologies, such as carbon filters and biofilters, to remove odours from the air.

In addition, regular cleaning and maintenance of the facility can help to reduce the accumulation of organic matter and the growth of microorganisms, which can decrease the production of odours. Proper training of employees on odour management and good housekeeping practices is also important.

Anotec Environmental is a leading provider of odour management solutions. Their products and services are specifically designed to neutralize a wide range of odours, reduce the production of odours, and improve the overall air quality of these facilities.

One of the key products offered by Anotec Environmental is their line of odour neutralizing agents. These agents are specifically formulated to neutralize odours caused by organic matter decomposition, chemical reactions, and microorganisms. These agents can be used in a variety of applications such as air handling units, biofilters, and chemical scrubbers to effectively remove odours from the air.

In addition to odour neutralizing agents, Anotec Environmental also offers a line of natural microorganisms that can be used to break down organic matter and reduce the production of odours. These microorganisms can be used in applications such as sludge treatment tanks and lagoons to help reduce odours.

Other services include odour assessments, odour control system design and installation, and ongoing support. They conduct odour assessments to identify the source of odours and recommend appropriate solutions. They also provide regular maintenance and monitoring services to ensure that the odour management plan is effective.

Anotec Environmental provides a comprehensive range of products and services that effectively manage odours in water treatment facilities. By partnering with Anotec Environmental, water treatment facilities can implement effective odour management strategies that prioritize the health and safety of employees and the surrounding community.

SIMPLE ANOTEC ENVIRONMENTAL ODOUR CONTROL

With increasing Environment Protection Authority (EPA), WorkSafe and council requirements, dust and odours can no longer be managed with a simple garden hose.

In providing a solution, ANOTEC has leveraged its more than 20 years of experience across Australia and New Zealand to reduce business costs and help them find best practice equipment for the task. ANOTEC works with landfills and transfer station owners/operators to provide a custom solution to the challenges within the industry. What is it worth to a company to be issued an abatement notice over a site? That’s compared to paying a modest cost for an odour and dust management solution, allowing you to continue working uninterrupted. The technology utilises pumps to generate microscopic air droplets capable of weighing down and suppressing dust and odour.

The key to effective dust suppression is creating minute water droplets in the fine micron range that are a similar size to the dust particles the site manager is hoping to suppress. Splitting water up into micron-sized droplets increases the opportunity for dust suppression, including dust in the harmful particulate matter 10 size range. For odour control, water is the carrier of a low dose odour elimination product carried within the droplet itself. Eliminating odours by oxidation or encapsulation renders the molecule odourless, preventing neighbouring businesses being adversely affected by a business’ operations. Inferior products with low pressure units, or units without pressure pumps, create a much larger droplet that simply moves around the dust particle.

This fails to collide with the dust particle and weigh it down, leading to further operational problems such as excessive surface water and run off. He says this is great for wetting down dust already on the floor, but ineffective at hitting the airborne dust fractions or keeping people safe from breathing these particles in. Conversely, splitting a normal droplet several thousand times over creates a high surface area, low volume droplet – creating millions of opportunities to knock out dust. Many of the droplets evaporate, preventing unwanted runoff and welcomed cooling in the hot Australian climate. Finer droplets outside are susceptible to wind, while heavier droplets tend to be not so susceptible, so it is application-driven. Medium pressure units are good outdoors, addressing both airborne dust and potentially dampening down on the ground, or a stockpile you can’t reach with a water cart. You’re minimising the dust being put into the air while addressing airborne dust. Waste industry will have its own operational constraints and if we can save water usage, we’re going to be able to save on odour product usage and costs as well – adding value to our clients. Getting close to the source of the dust or odour and apply some fogging around that area, it is far better than doing it outside the building or on the periphery of your site. This is because you’ve got the same amount of odour spread out over a wider distance and its harder to control.

Pahang DOE: Water supply at Sungai Semantan plant free from odour contamination

KUANTAN, Oct 11 ― The water at the Semantan raw water plant in Temerloh, which is transferred to the Langat and Cheras water treatment plants (LRA) in Selangor, is free from any odour contamination from Saturday until today. Pahang Department of Environment (DOE) director Rosli Zul said the reading was zero based on the measurement of the rate of odour pollution called Threshold Odour Number (TON) to indicate that the quality of water on the time and days in question was normal until today. “DOE obtained the date from the operator at the Semantan water plant. According to the standard operating procedure, the operator must monitor the odour quality and measure the odour pollution every hour. “The Pahang DOE will act if the data they recorded odour pollution, but until today, the water at the Semantan plant is normal, the TON reading is zero,” he said when contacted by Bernama today. However, he did not denied a little odour pollution was recorded on Friday (October 7) at the plant at 9.45pm and it was detected much earlier at 7pm, at the Langat and Cheras LRA. “The process of transferring raw water from the Semantan plant to the two water treatment plants will take 12 hours and based on the monitoring record from 8am to 8pm on October 7, no pollution took place and it was only detected at 9.45pm,” he said. Rosli said after 11pm on the same day, the TON reading of raw water at the Semantan plant had returned to normal and did not indicate any odour pollution. He said the odour pollution was detected again at the Semantan plant at a level of four TON at dawn (5am) on October 8 (Saturday) and the situation returned to normal after 9am. ― Bernama
