Innovative Practices for Water Conservation at JPL
1)The use of Ultra Filtration at the Downstream of Mixed Bed to reduce theColloidal Silica for minimizing the Boiler Blow down This greatly prevents the lossof Heat energy from being drained away and eliminates the detrimental effects ofth Sili i M i t & C t d ti i hi d th b d tthe carryover Silica in Main steam & Cost reduction is achieved thereby due tosaving precious DM water

2) Reduction in the Ionic Load & Turbidity of Clarified water reduced theusage of water for Backwash and Regeneration by increasing the Outputbetween Backwash(OBB) & Output between Regeneration(OBR),thebetween Backwash(OBB) & Output between Regeneration(OBR),thefrequency of Regeneration and Backwash is reduced. By this huge savingsis realized .
