Conventional wastewater treatment technologies involve use of external inputs of recurring chemicals and also use of electricity, only to cause destruction/separation/disposal of valuable plant nutrients. This paper discusses ecological wastewater treatment, with a case study of dairy wastewater. In the ecological approach, biosanitizer eco-chips are first used to make the wastewater eco-friendly. The treated wastewater, when given to plants, the nutrients get properly utilized and nuisance-causing bacteria, pathogens and pests do not proliferate. This is, effectively an ecological control of odour, pathogens and pests, instead of using toxic chemicals. Also the organic (BOD, COD) and inorganic nutrients are removed through utilization. It also explains biosanitizer reaction and also the pilot plant runs on dairy wastewater. It also offers comparative evaluation of conventional treatment of dairy wastewater and the ecological treatment using biosanitizer.
