Corrosion and Odour Control in Wastewater and Sewage Treatment Plants

Neutralise Corrosive Gases and Odour in Wastewater and Sewage Treatment Plants

Wastewater treatment is the process of removing contaminants from wastewater and household sewage. It includes physical, chemical, and biological processes to remove contaminants. These processes are controlled by various electronics systems controlled by a distributed control system. 

Various gases emitted during wastewater treatment are typically indicative of anaerobic conditions. The early stages of processing tend to produce toxic gases such as Hydrogen Sulphide (H₂S), Sulphur Dioxide (SO₂), Bromine (Br₂), Oxides of Nitrogen (NOx), Chlorine (Cl₂), etc., which can be corrosive in higher concentrations. These gases also contribute to unpleasant odours in the environment.

Removing corrosive gases is of utmost importance to ensure the smooth operation of automation systems. Also, there is a growing demand for high-efficiency odour control systems at wastewater treatment plants. Malodorous gases require gas phase filtration before being exhausted from irrigation tanks and pumping stations.

Areas Generate Toxic Gases

• Wastewater and sewage collection/processing facilities
• Clarifiers
• Digesters
• Aeration basins
• Lagoons
• Pumping stations
• Headworks
• Sludge handling areas etc.

Chemical cleaning compounds, solid waste, and other accumulated human garbage increase the natural contamination of sewage water thus ultimately leading to air contamination. Nuisance odours and gases evade the best preventative efforts of modern wastewater treatment plants. Industrial odour control is a complex and difficult task. Even as waste disposal workers are now beginning to understand the use of green alternatives for odour control, researchers are seeking solutions from even more areas of technology.

Gas Phase Filtration System – The Most Effective Way of Removing Airborne Molecular Contamination

Bry-Air Gas Phase Filtration Systems protect electronic equipment and devices from the threat of abrupt failures due to corrosive gases. It reduces downtime by removing corrosive gases through the process of adsorption and chemisorption. It is designed to maintain the ANSI/ISA-71.04-2013 standard, IEC standards and various other environmental standards followed by electronics manufacturers.

These GPF systems also neutralise odourous gases and make the environment comfortable for humans.

Bry-Air: A Step Ahead, Always

Bry-Air is the only Gas Phase Filtration Company in India having its own R&D and Testing Lab for granular media and chemical filters. Backed by world-class technology and systems, the laboratory is capable of testing the performance of impregnated/non-impregnated loose granular media and impregnated/non-impregnated air cleaning devices such as chemical filters, under one roof. The tests are conducted as per ISO/ASHRAE Standard 145.1 and BSR/ASHRAE Standard 145.2/ISO Standard 11155-2 guidelines. The core objectives of the tests are to assess the performance and efficiency of loose granular sorptive media and chemical filters in any particular application.
