Wastewater characterised by elevated sugar levels and additional organic components such as hop resins and husks. It commonly contains suspended solids, salts, nutrients (like nitrogen and phosphorus), and occasionally includes brewing-related chemicals such as cleaning agents or additives, leading to heightened biological oxygen demand (BOD).

Our ZLD solutions for the Brewery wastewaters offer the following benefits:

• Separation of Crystal Clear Water with a TDS of less than 150 ppm
• Dry solids with less than 5% (w/w) moisture
• Continuous operation, 24 hours a day, 7 days a week.
• PLC-SCADA-based control and automation, with a single operator managing plant operations from the ground floor panel room.
• Eliminating manual or physical cleaning of the Evaporator & Dryer plant, with chemical cleaning required only once every 15 days.

The composition of wastewater generated by this industry can vary depending on the specific processes and activities involved. However, common pollutants found in food and beverages wastewater include organic matter, nutrients like nitrogen and phosphorus, acids & alkali, oil, and chemicals, such as cleaning agents, disinfectants, and food additives.

Production of every litre of alcohol, generates 3-10 litres of wastewater called Raw Spent Wash (RSW) or Vinasse. RSW exhibits high Chemical Oxygen Demand (COD) levels of up to 160,000 mg/L and Biochemical Oxygen Demand (BOD) levels reaching up to 80,000 mg/L. To manage this, RSW is subjected to anaerobic bio digestion for generating biogas. The resulting Biomethanated Spent Wash (BMSW) contains non-condensable (gases) like ammonia and hydrogen sulphide.

Our ZLD solutions for molasses based distilleries offer several benefits:

• Crystal Clear water with TDS less than 250 ppm, suitable for recycling into the fermentation process, thereby reducing the need for fresh water and promoting sustainability.
• Obtaining a permit from the Central Pollution Control Board for year-round distillery operation, ensuring optimal utilization of installed capacity and increased profitability.
• The Multiple Effect Evaporator (MEE) output concentrations can be tailored to different applications:
  • 30% (w/w): Suitable for Bio-composting
  • 60% (w/w): Appropriate for incineration in regular boiler
  • 98% (w/w): Ideal for use as organic fertilizer

This is a highly toxic category of wastewaters originating from industrial manufacturing processes for fertilizers, pesticides, insecticides, and fungicides. These wastewaters are a complex mixture of salts, organics, solvents and gases, and are therefore hazardous to the environment.

Our ZLD solutions for the Agrochemical wastewaters offer the following benefits:

• Separation of Crystal Clear Water with a TDS of less than 250 ppm
• Dry solids with less than 5% (w/w) moisture
• Continuous operation, 24 hours a day, 7 days a week.
• PLC-SCADA-based control and automation, with a single operator managing plant operations from the ground floor panel room.
• Eliminating manual or physical cleaning of the Evaporator & Dryer plant, with chemical cleaning required only once every 15 days.

Commonly known as stillage, this effluent is generated during alcohol production such as ethanol, particularly from grains like corn, wheat, barley, or rye. It comprises a diverse range of components, including organic compounds like sugars & starches, suspended solids, nutrients, and chemicals employed in the fermentation and distillation processes. The significant organic load and the potential for pollution make its proper management crucial for environmental sustainability.

Our ZLD solutions for the Grain-based Distillery wastewater offer the following benefits:

• Separation of Crystal Clear Water with a TDS of less than 250 ppm
• Specialized Rotary Steam Tube Bundle Dryer, specifically designed for DDGS (Distillers Dry Grain Solubles), yields a 90% (w/w) dried product. It is sold as a valuable cattle feed by our customers.
• Continuous operation, 24 hours a day, 7 days a week.
• PLC-SCADA-based control and automation, with a single operator managing plant operations from the ground floor panel room.
• Eliminating manual or physical cleaning of the Evaporator & Dryer plant, with chemical cleaning required only once every 15 days.

The discharge produced throughout different stages of ceramic production, encompassing shaping, glazing, decorating, and firing processes, exhibits a diverse composition influenced by the specific manufacturing methods and materials employed. Typically, it comprises clay, silica, feldspar, organic additives, binders, colorants, and heavy metals like lead, cadmium, chromium, along with alkaline substances that modify the wastewater's pH. All these substances contribute to turbidity and suspended solids, posing great environmental hazards.

At SS Techno, we treat these kind of diverse wastewater, ensuring the restoration of crystal-clear water to the production process. In one of our customer's facility within this industry, we have effectively isolated Sodium Nitrate salt that is a commercially viable product.

Our ZLD solutions for the Ceramic Industry wastewaters offer the following benefits:

• Separation of Crystal Clear Water with a TDS of less than 150 ppm
• Dry solids with less than 5% (w/w) moisture, often sold as a product.
• Continuous operation, 24 hours a day, 7 days a week.
• PLC-SCADA-based control and automation, with a single operator managing plant operations from the ground floor panel room.
• Eliminating manual or physical cleaning of the Evaporator & Dryer plant, with chemical cleaning required only once every 15 days.

Palm Oil Mill Effluent (POME) is characterized by exceptionally high Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) values, presenting a significant environmental pollution burden. Typically stored in expansive lagoons, the conventional method for mitigating BOD and COD involves biogas generation from these lagoons. Despite this treatment, the challenge of responsible discharge to the environment persists. Leveraging extensive knowledge and experience, SS Techno has pioneered an Advanced Technology to achieve Zero Liquid Discharge (ZLD) for POME.

The notable benefits include:

• No POME needs to be discharged outside the factory.
• No need for lagoons - saving land space
• No need for Biogas Plant. For mills who already have Biogas Plants, the POME after bio-digesters can be also treated with the SS Techno ZLD scheme
• Crystal-clear condensate water with TDS less than 250 ppm, completely recyclable to the boiler after tertiary treatment.
• Continuous operation, 24 hours a day, 7 days a week.
