ABSTRACT:
There is disclosed a portable assembly for treating hazardous waste water having a plurality of paired filter units having filter mediums and operated at high filter rates to minimize solids build up wherein solids are caused to be smashed and broken by shear forces and wherein chemicals are sequentially added to facilitate solids reduction, to oxidize organic compounds and to precipitate dissolved solids and wherein the process stream is subjected to ultraviolet light to reduce organic loading and downstream ultra filtration units to further reduce solids followed by reverse osmosis and/or ionization treatment.
