Treatment for Textile Industry

  textile waste water

Effluents generated by the textile industry can be broadly classified into three categories based on thier contributing process:
        Pre-treatment (scouring, desizing)
Dyeing and washing
Finishing (softeners)

Over the years Rochem has mastered the application of direct recovery of >85% of RO permeat from the dyeing and washing stream without any conventional ETP treatment and the treatment of the pre and post dyeing with primary treatment.

Due to this, the majority can be treated without ETP and also sludge generation from ETP reduced.


  • Higher recovery rate 
  • Application on raw equalized effluent helps avoid high costs of chemical and energy associated with conventional ETPs
  • Capacity is enhanced as the need to upgrade the existing ETP structure is avoid and saves investment in land and civil cost
  • RO reject can be further reduced, thereby reducing the volume for evaporation, resulting in further savings.


Backgroud: A factory expansion resulted in higher effluent generation which needed a compact treatment scheme to achieve zero discharge.

Plant installed: Two stage Rochem PF-RO System (Microprocessor controlled, fully fail safe and unattended operation).

Input: 800 cum/day of raw untreated waste water as input

Recovery Rate: 1st stage:75%
 2nd stage:65%
 Total Recovery 80%

Salient features
The system was commissioned for direct intake of compatible stream to recover 80% of the effluents as RO permeate for reuse within dyeing process. The small volume of non compatible stream like pre and post treatment are being treated after ETP treatment.

The installation was considerably reduced the ETP footprint which would have otherwise been required for treatment of the total volume of 1600 m³.

the total capacity is currently under expansion to handle the total effluent generated of 1600 /day.
