Project
Background
The Food, Ice cream and Dairy industry involve mixing ingredients, pasteurization, homogenization, aging, churning/freezing, and packaging. This process generates significant wastewater. IGLOO's specific volume depends on production scale, but expects high level of organic matter (milk, fruit), fats, oils, and grease from the product itself. Cleaning chemicals and sugar residues add to the wastewater load, requiring proper treatment for environmental compliance.
The CETP
Key Features
Solutions
Kingsley implemented a Biological Anaerobic (UASB) & Aerobic Treatment Process to address the challenges. The reasons of choosing this technology are the following-
- DAF (Dissolved Air Floatation): DAF is installed for removing contaminants such as fats, oils, suspended solids, and organic matter. As a result, COD is significantly reduced.
- UASB Powerhouse: The UASB stage excels at breaking down organic matter, a major component of food industry wastewater. This includes high concentrations of carbohydrates, proteins, and fats originating from the wastewater.
- Aerobic Polish: Following the UASB, the aerobic treatment process further polishes the effluent by removing any remaining organic matter that may have escaped the UASB stage. This two-stage approach ensures a high level of organic matter removal, leading to cleaner effluent.
- Cost-Effectiveness: The anaerobic nature of the UASB stage doesn't require oxygen for treatment, reducing energy consumption compared to solely aerobic processes. This translates to potential cost savings for food industries.
- Improved Sludge Management: The UASB process generates a specific type of sludge with good settling characteristics, simplifying sludge management compared to some other biological treatment methods.
- Flexibility and Adaptability: Food production often involves seasonal variations and diverse product lines. The UASB-aerobic combination can handle these fluctuations in organic matter content and wastewater composition more effectively compared to some single-stage treatment processes.
- Reduced Discharge Concerns: The high-quality effluent produced by this two-stage treatment meets stricter discharge standards, minimizing concerns about environmental impact.
- Potential for Reuse: In some cases, the treated effluent might even be suitable for certain non-potable reuse applications within the food industry, potentially reducing reliance on freshwater resources.
Kingsley provided its visionary solution by choosing Common Effluent Treatment Plant, keeping in mind the client’s requirement and environmental safety.
Main Characteristics of Common Effluent Treatment Plant (CETP)
- Treats wastewater from diverse industries in an industrial zone.
- Aims for compliance with environmental regulations or potential reuse.
- Treats wastewater through stages: solid removal, biological breakdown, clarification, optional disinfection, discharge/reuse.
- Participating industries share responsibility for operating and maintaining the CETP, including cost-sharing for treatment, infrastructure, personnel.
- Offers effective solution for industries, sharing costs and responsibilities for operation and maintenance.
