Treated municipal wastewater (MWW) is recognized as a viable alternative cooling water source for power generation. One of the key challenges for the successful use of the effluent from wastewater treatment facilities for cooling is the potential for significant condenser fouling when this water is concentrated as much as 4–6 times in recirculating cooling systems.
Well maintained heat exchangers perform the function of cooling municipal wastewater heated during various processes. This helps to optimize temperatures of water flow and to increase the overall energy efficiency of the wastewater treatment plant.
In waste water treatment plants, plate heat exchangers play a vital role in maintaining optimal temperatures within specified tolerance ranges for anaerobic digesters which promote the growth of microbes that remove pollutants.
