By definition, Zero Liquid Discharge means that not a single drop of liquid goes out of the premises. We at SS Techno make some of the best Zero Liquid Discharge plants in India. Our plants are tailor-made, taking into account the nature of the wastewater. Evaporators, although capital-intensive, are a necessary investment that ensures the proper treatment of industrial wastewater.
We have a vast experience in treating the wastewater from a wide array of industries.
Molasses based distillery effluent known as spent wash/vinasse/dunder/thin slops, is one of the most difficult applications for evaporators. These effluents are characterized by a high Chemical Oxygen Demand (COD) and high volumes, creating a heavy pollution load on the environment. SS Techno has developed various Innovative evaporation technologies to achieve total Zero Liquid Discharge solutions for the distillery industry.
SS Techno evaporators are designed for any steam pressure available with the customer, and are guaranteed to give crystal clear condensate. The entire water can be recycled after proper polishing treatment. Raw effluent/post-biogas effluent have been successfully handled. Special applications using alcohol vapours/excess vapours from sugar industry, instead of boiler steam have been also implemented.
Concentration of solids to any level from 30% to 95% (w/w) has been successfully achieved in various plants as per the need of the customer. Concentrate with 70% solids (w/w) has been successfully incinerated in regular boiler by mixing it with primary fuel such as bagasse/wood chips/rice husk etc.
Grain based distillery effluents are popularly known as thin slops and are concentrated to be used as cattle feed, by mixing with Distillers Wet Grain Solubles (DWGS).
