Sewage Treatment Plant (STP) design calculation software refers to specialized engineering tools used to required to treat wastewater . These programs replace manual spreadsheets by calculating plant capacity (KLD/MLD), sizing tanks for technologies like MBBR and SBR , and ensuring effluent meets environmental discharge standards.
