Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution can be reduced by separating harmful substances from the natural sources like air, water, soil, ocean and these harmful substances can be used for other purposes, it can be recycled and reused. Toxic containments present in air or smoke can be separated by various techniques & equipment like Cyclonic Separation, Scrubber, dust collectors, thermal oxidizers, cyclones, blowers, Vapor recovery systems, Dissolved air flotation, API oil-water separators, Biofilters, Aerated lagoons, Constructed wetlands, Electrostatic precipitators, Wastewater quality indicators, Air Ventilation, Multicyclones, Mist collectors, Bag Filters, Photocatalysis, Catalytic converters and electrostatic precipitators. These harmful substances can be reduced by treatment process like Physicochemical Treatment, Biological Treatment, Activated Carbon Treatment etc. Introduction of Novel Technologies has led a path to reduce and prevent the natural resources being polluted by our social activites. These techniques which they have employed in the Industries sector, Agriculture sector, Urban and Rural areas starts reduce the waste, treating the waste products, recycling the waste products, implementing the water and energy saving practices, implementing Eco-friendly practices etc. By these ideas and technologies we can make our world even more better for our future generation.
Wastewater treatment is a process used to convert wastewater into an effluent (outflowing of water to a receiving body of water) that can be returned to the water cycle with minimal impact on the environment or directly reused. The treatment process takes place in a wastewater treatment plant (WWTP), often referred to as a Water Resource Recovery Facility (WRRF) or a sewage treatment plant. Pollutants in municipal wastewater (households and small industries) are removed or broken down. This session covers all the attributes of Pollution and Wastewater Treatment Process.
