Zero Liquid Discharge Systems is not about putting big evaporators, crystallizers at end of effluent treatment plants. It is a way of making industries more accountable for the water intake and building trust of communities in large scale industrial set ups. It has been common phenomenon world wide that large scale industries are not welcome into any area because they cause problem with there liquid and air discharges. More over due to rapid urbanization and high number of industries with limited water sources there is no chance of natural dilution, diffusion, self adjustment, self purification, process to occur in water bodies. So governments all over the world are implementing Zero Liquid Policy that help companies builds trust with local communities, improve brand value and makes them accountable to resources of the nation. Zero Liquid Discharge policy mandates that all the water and liquids waste to be recycled and reused in the industrial compound itself. To achieve Zero Liquid Discharge the whole cycle of intake, process and treatment of water, effluent has be optimized.
