Need info on the type of filter to be used to recycle greywater in Bangalore,Karnataka


We are from Bangalore and are doing research and development on greywater recycling unit. We want to recycle grey water which has sodium/detergent materials and use the recycled water for the washing purpose (equipment/ automobile/ apparel etc.) only.

The unit would be installed in a residence. Could you please suggest us filters that we could use in the unit and any additional information that will help us in our research.
