Controlling odor coming out from the waste water treatment plants are becoming one of the most crucial factors in the recent days. Odor coming out from the sewage and waste water treatment plants causes several health issues. The pollutants coming out from the sewage treatment plants do have hydrogen sulfide and ammonia in large concentrations. Theses pollutants present in higher proportions in the air, results in significant air pollution. It is better to use effective odor control systems in the industrial sectors to minimize the concentration of hazardous pollutants.
Background of Sewage Treatment Plants:
Any type of location or processes where the wastewater is collected and treated, there is a release of harmful odors that are dangerous for the health. When the waste water plants are located near to the residential areas, there is a great effect on the people living there. The odor coming out from the sewage plants results from the anaerobic degradation of the waste or septic condition of the domestic and industrial waste. The governments of various countries are suggesting the waste water treatment industries to install effective odor control systems to reduce the harmful effects. Due to the invention of modern technologies and machines, there is also a great modification in the odor control techniques. It is obvious that you should control the concentration of the harmful gasses and odors.
Technologies to Reduce the Concentration of Odors
Various technologies are involved nowadays in order to control odor generation. Among all of them, the biological filters, chemical scrubbers, and carbon filters are powerful enough to reduce the concentration of the harmful pollutants of the sewage treatment plants. Let us see some of the technologies to control the odors.
Biological Filters:
The biofilters are one of the most important technologies to control the harmful odors. These technologies are quite effective in controlling the odors coming out from the waste water and sewage treatment plants. These technologies are easy to handle and operate. They are useful to minimize the odors caused due to the degradation of the organic components. In the biofilters, a bed of media consisting microbes is present. The microbial components are mainly aerobic and anaerobic bacteria. They degrade the waste particles into smaller and harmless components. The biofilters can reduce the concentration of ammonia and hydrogen sulfide to about 90% from the atmosphere.
Liquid Phase Technologies:
This technology involves the treatment of the wastewater to control the harmful odors. This technology is effective in controlling the release of the corrosion-causing elements from the waste water stream. In the liquid phase methodologies, chemicals are also in the waste water so that the odors can react with the chemicals and change into harmless forms. This technology also offers corrosion control procedures to the wastewater treatment plants.
Carbon Scrubbers:
These are important and highly efficient in controlling odors coming out from the sewage treatment plants. In this process, the wastewater passes through the bed of adsorbent carbon. The odors get attracted on the carbon and the water becomes free from the pollutants. This technology is best for the treatment of the hydrogen sulfide or sulfur related compounds as well.
These are some of the effective types of odor controlling technologies available in the market. Numerous companies that offer FRP baffle tanks, cylinders and pipes for holding the waste water and controlling the odors. The EcoEX odor control systems are durable and affordable.
