Background:

Power plant wastewater comes mainly from cooling systems, equipment cleaning and boiler discharge. The wastewater may contain suspended solids, chemicals, oils and heavy metals.

Equipment Used:

– Cooling water pumps: are used to transfer cooling water from cooling towers or cooling ponds to power generation equipment. These pumps need to be corrosion and abrasion resistant to cope with solid particles and chemicals in the water.
– Air compressors and air flotation units: Air compressors provide high-pressure air to support air flotation units to remove suspended solids and oil from wastewater. The air flotation device is effective in removing floating oil and fine particles from the water.
– Blower: In the aeration unit of wastewater treatment, the blower is used to provide oxygen to the activated sludge process to support microbial degradation of organic matter and pollutants in the wastewater.
– Centrifugal pumps: are used to transfer the treated wastewater to the reuse system or discharge point, ensuring that the flow and pressure of the treated water meets the requirements.
– Result: Through the efficient application of cooling water pumps, air compressors and blowers, suspended solids, oils and chemical pollutants are effectively removed from the wastewater of the power plant, and the treated wastewater meets the environmental discharge standards and reduces the impact on the environment.
