GPT is a sustainable solutions provider engaged in designing and manufacturing industrial wastewater and effluent treatment plant in India. GPT's proprietary Membrane Distillation (MD) process is a specifically designed innovative membrane process that helps to treat wastewater with high salinity efficiently, economically and sustainably. We offer MD as part of ETP and ZLD plants to improve energy efficiency and operational effectiveness.

 

The MD process relies on water vapour transport through porous hydrophobic membranes using partial vapour pressure difference across the hydrophobic membrane.

​

The MD process recovers product water from a feed source at significantly lower energy compared to conventional methods. The technology is ideally suited for industrial wastewater and complex effluent treatment applications. MD is also considered to be sustainable membrane technology for low-temperature dewatering of food and beverages, ZLD, brine minimization and desalination etc to meet regulatory compliances, reduce OpEx and increase water usage efficiency.

​

MD can be a promising alternative to conventional thermal processes. MD process eliminates the need for complex and expensive evaporation and crystallization unit operations. Moreover, the process economics becomes extremely favourable if waste heat or natural heat source (i.e. solar evaporation) are available- reducing per unit cost of product water and thereby achieving integrated, compact, economical and sustainable process solutions.
