In the present time, when people are becoming increasingly
aware about their health, control of odours has moved from an afterthought to a
primary concern. The treatment plants collect effluents from industrial as well
as domestic sectors, discharging large amounts of unpleasant odours, which act
as nuisance both for the staff as well as local residents.
There are certain causes, which are responsible for such
disagreeable odour liberated from the wastewater treatment plants. With the
rise in temperature of the environment, the temperature of water also
increases. In warm water, aerobic bacteria become much active and they consume
more oxygen, which results in less concentrations of dissolved oxygen. Lower
levels of dissolved oxygen along with higher temperatures lead to anoxic zones.
Anoxic refers to a situation, when there is complete depletion of oxygen. Such
a situation leads to the release of sulphur dioxide and other toxic gases,
which are responsible for the offensive odours.
Thus, most of the industries have now availed to
highly custom-built odour control equipment, in order to prevent the repulsive odours as well as the obnoxious elements emitted from these sectors.
Definition of the systems of odour control
The ideal odour control applications are being lodged by the leading industries, in order to eliminate the odour generated from wastewater treatment plants and sewage waste. Most of these sewage treatment plants make use of advanced technological innovation in order to treat the resources effectively. Use of FRP over traditional materials for these odour controlling techniques have been popularized in today’s era. Baffle walls and tank covers made of FRP are proved to be quite advantageous in odour control.
Types of the Odour Control TechnologiesThere are a few types of
odour control systems, which act quite effectually for controlling odour. Some of those techniques adopted by industries for controlling odour are as follows:
1. Bio-Scrubbers-
These odour control techniques provide an eco-friendly solution to deal with the abhorrent smell as well the dangerous elements generated from the treatment plants. They work by minimizing the sewage content and limiting the flow of wastes, thus leading to a healthy environment.
2. Carbon Scrubbers-
The carbon-dioxide scrubbers are used especially in industrial chimneys as well as rebreathers to reduce the obnoxious gases as well as pollutants released from here. These scrubbers use a series of products along with activated carbon, which improves the resources by removing the harmful components.
3. Chemical Scrubbers-
This application use a high dose of chemicals to treat the wastewater, thus, getting rid of the harmful components as well as the offensive smell. They are quite on-demand in the industrial field mainly used for discarding the unwanted elements. They are primarily designed for reducing Hydrogen Sulphide and Ammonia.
