Process condensate generated due to condensation of steam in heat exchangers and jacketed kettles etc. represents a real value to customers. In most cases the condensate becomes contaminated and cannot be reused in the boiler without pretreatment. The conventional methods of ion exchange mean cooling the water down to 27°C to 32°C. By using specialty membranes, we can process condensate at temperature up to 82°C, thereby offering significant savings in heat energy savings.

Many plants such as sugar and paper mills and dairies also produce products using thermal evaporation. The condensate from the evaporators usually has a small amount of their product. It is possible to concentrate the product and reduce the load on the waste treatment plant and produce high quality water suitable for reuse.

The treated condensate or NF/RO permeate can be used for various utility operations such as cooling, boiler and process make up. Examples of polishing include TOC, BOD, alcohol and other constituents like ammonium nitrate (from ammonia) from dirty condensate stream.
