Modified sewage treatment plants will reduce presence of phosphorous and nitrates in water bodies
Several lakes in Bengaluru such as Hulimavu and Puttenahalli lakes near J.P. Nagar, Subramanyapura lake in Uttarahalli and Arakere on Bannerghatta Road are under threat on account of overgrowth of water hyacinth. Bangalore Water Supply and Sewerage Board (BWSSB) has proposed to upgrade the existing 20 sewage treatment plants (STP) to include modifications required for removal of biological nutrients that spur their growth. According to experts, one of the reasons for the overgrowth is the presence of phosphorus, potassium, and nitrates, known as biological nutrients, in abundance. This is attributed to the flow of sewage into the water bodies that not only compromises water quality, but also promotes the growth of microphytes and macrophytes such as algae and water hyacinth.More Related News
