Pure=OH ®


Large volumes of water are used in the textile industries for many purposes including washing, scouring, dyeing,printing, bleaching, and finishing cloth. These processes generate large amounts of waste water. Moreover, due to the increasing cost of wastewater treatment and stricter government regulations imposed on wastewater disposal, demands for new technologies have become more urgent to recycle the waste ( water and auxiliary chemicals) economically and ecologically. In addition, textile effluent contains valuable substances that can be recovered.

Inception of New Technology for Reuse of Waste Caustic

Since last 1 year we had worked for use of waste caustic and establish a process of Purification and Reuse of NaOH back to Mercerization Process on smaller scale and series of Pilot trials had done at Industries and than great results was achieved. The quality of Reusable caustic had achieved . One Project is finalized on the result achieved and the benefits are as below.

  • Less spending on caustic and acid materials.
  • Reduced waste treatment costs and effluent volumes
  • Lower energy consumption by Hollow Fibre D-PF membrane with backwashable future.
  • Decreased wastewater TDS/Sodium
  • Waste Caustic stream after Mercerization washing bath drain of 3 % to 5 % will be purified by Pure=OH system.
  • Concentrated size materials will be converted into Biogas for Fuel in CRP, plant, Which reduces great load on ETP and saves Energy in Aerobic Biodegradation at ETP.
  • Pure Recovered Caustic of by our system safely & than taken to Evaporation plant till 35 % by CRP for reuse . Cost of Caustic (100%) Basis is 16 Rs/Kg including all cost and ROI is 12 Month.

The Challenge- How Much is Your Caustic Really Costing You ?

The Challenge- How Much is Your Caustic Really Costing You ?

Caustic is used in the textile industry in two major applications : Purification of cellulosic fibers, to remove hemicellulose and other impurities from the fibers, to produce high purity cellulose, and higher quality dyeing and printing. The spent caustic, although still at high strength, cannot be reused in any of the plant operations due to the high concentration of contaminants. Hence, it is usually sent to the wastewater treatment plants, where in most causes it is neutralized with acid, increasing even more the costs of operation. Processing Units with Mercerization process had heavy load of NaOH as well as COD due to presence of starch in it increases TDS as well as COD at ETP
