By definition, Zero Liquid Discharge (ZLD) means that not a single drop of liquid goes out of the premises. SS Techno makes some of the best Zero Liquid Discharge plants in India. SS Techno 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.
SS Techno has vast experience in treating the Wastewater from a wide range of industries.
The salient features of our ZLD systems are
Grain based distillery effluents are popularly known as thin slops. It is concentrated and mixed with Distillers Wet Grain Solubles (DWGS) for use as animal / cattle feed.
We offer special purpose conduction type drying system to dry these solids to less than 10% moisture called DDGS (Distillers Dry Grain Solubles). These dry solids are used as animal / cattle feed. The dried solids has better shelf life for storage.
Molasses based distillery effluent known as Spent Wash/Vinasse/Dunder 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 a number of innovative evaporation technologies to achieve total Zero Liquid Discharge solutions for the distillery industry.
SS Techno ZLD systems are designed to use steam at any available pressure, Alcohol-water vapor, Thermal oil/Hot oil, any other available heat source.
Concentration of solids upto 98% (w/w) dry powder form (non-hygroscopic) has been successfully achieved in various plants as per the need of the customer. The final output of the ZLD plant can be used for Bio-Composting or Incineration or as Potash-rich Organic Fertilizer.
Concentrated solids (70% (w/w)) have been successfully incinerated in regular steam boiler by mixing it with primary fuel such as bagasse/wood chips/rice husk etc.
Salient features of ZLD systems are:
Multipressure Vacuum Distillation/ Atmospheric Distillation
