Project Overview
Small-scale sustainable household grey-water recycling (S3HWR) project attempts to evolve an intra-household (HH) greywater recycling technology suitable for India using a combination of anaerobic and aerobic systems that can function within our socio-culturally acceptable construct of water recycling. Within HH, greywater recycling systems stand best to succeed to meet emerging shortages /outages. Proven /sustainable (efficient, <1m3/d) technology options do not exist today. We combine primary anaerobic (biofilm or AnSBR), with a (1of4) femto-power aerator-ozonator /constructed wetland /microbial electrogenic cell / solar photocatalyzer based secondary treatment to remove detergents, anti-microbials and bacterial loads and make recycled water clear, odour /froth free and socio-culturally acceptable. After rigourous trials to withstand perturbations we will build intra-HH and test in situ greywater recyclers providing recycled water of <10BOD @
