Condensate Polishing Wastewater Recovery

The textile & polyester yarn industry is one of the highest consumers of fresh water and creators of highly toxic wastewater. The only sustainable path forward is to regulate fresh-water draw through aggressive recovery of the effluent a single manufacturing unit generates.

With 25+ years of experience, Ahura Aqua channels raw water through biological & physio-chemical treatment, clarification & filtration, and finally membrane separation — recovering up to 93% of wastewater back into the production cycle.

              Closed-Loop Water Recovery Cycle
              
              Raw Water → Reuse

Textile effluent is among the most contaminated streams in industry. We close the loop — every litre is driven through a multi-barrier train and returned to process, minimising both fresh-water intake and toxic discharge.

              Raw → Reuse

Textile discharge carries an exceptional load of colour, dyes and dissolved solids. Each parameter is driven from raw-effluent extremes down to reuse-grade targets through a specific treatment stage.
