Water clean enough to drink

Wastewater from dyehouse effluent is a major source of pollution in the clothing industry. Where our products are dyed, the water is recovered, cleaned and recirculated. After settling and skimming, the water is filtered using reverse osmosis and distillation. This is basically sucking up water through really fine sand over and over, then boiling it.

 

Salt is added back in so that the dye adheres and all the cruddy mulchy stuff left over is dried out and used for road markings. About 95% of the water is recirculated and recovered.

 

At the end, the water coming out of the filters and going back round to be reused again is crystal clear, literally clean enough to drink. Once it has been cleaned, it is then used at the input for the next batch. It is a closed loop system.
