The odour is common in those areas that are located near the waste water treatment and sewage treatment plants. Individuals who are living near these areas are always subjected to various harmful odours that cause health hazards. The poisonous pollutants like ammonia, hydrogen sulphide and carbon monoxide are responsible health issues if, they are inhaled. These gases results from various chemical reactions that take place inside the industrial zones. Not only these gases are dangerous for your health, they cause air pollution as well. It is the duty of the industry owners to implement certain techniques that can check these air pollutants to come out of industrial chimneys.
There are various odour control techniques that are used in these days. Among all, the chemical, carbon and biological scrubbers are gaining importance. These methods are widely used in various industrial sectors like petrochemicals, tanning industry, waste water and sewage treatment plants as well. These methods prevent the gases from getting mixed with air. There are various companies that offer these scrubbers based on fibreglass. FRP baffle tanks and pipes are used to collect the waste water and then the wastewater goes through various sedimentation processes. FRP odour controlling techniques offer various advantages.
• Carbon Scrubbers:
In this type of treatment, the stream of polluted water is passed through the bed of carbon that acts like the absorbent. The odour causing pollutants when passed through the carbon bed, they get attracted to it. It is one of the most common methods that are used in the sewage treatments plants. This scrubber is effective in controlling various types of odours. Hydrogen sulphide and other sulphur-related compounds are being purified by this method. But it is not too powerful in controlling ammonia and other harmful gases.
• Biological Filters:
It is one of the cheap forms of odour treatments that are used in most of the sewage treatment plants. This method does not require any chemical media. The one and only treatment media are the biological organisms. Biofilters are quite effective in treating various organic and aqueous gases. Here, the wastewater containing the harmful gases is passed through the media bed where the biological organisms degrade the pollutants and reduce the harmful effect. It is one of the cheapest and effective forms of odour control.
Apart from these two types of treatments; chemical scrubbers are also important in controlling the malodours. The carbon scrubbers and biological filters are easy to maintain and operate.
