Majority of the industries generate wastewater with high salinity. Conventional ‘Physico-chemical-biological’ treatment does not remove salinity. RO is limited with salt concentration in the feed water due to osmotic strength. Conventional distillation methods are popular for brine treatment and zero liquid discharge (ZLD). However, the conventional distillation units are complex in nature, it occupies more space, consume more energy and requires high capital investment (especially for smaller capacity – 1 to 100m3/day where the capital cost of the conventional thermal systems are around 50k USD to 10k USD/m3). The TS-30™ system is based on a novel thermal membrane process that can be operated using low-grade waste heat (60 deg C to 85 deg C) or solar energy. It requires around 30-40% lower CapEx and up to 50% lower OpEx for small scale (1 to 100m3/day) zero liquid discharge systems when compared to the current state of the art evaporators.
