This facility is the largest Effluent Treatment Plant within a dairy processing operation in Sri Lanka, underscoring Pelwatte Dairy’s commitment to aligning its operations with global environmental standards and strengthening its position in international markets.
Strategic Commitment to ESG and Responsible Growth
This investment reflects a deliberate and forward-looking strategy by the Board of Directors to embed Environmental, Social, and Governance (ESG) principles into core operations. As Pelwatte Dairy continues to scale its processing capacity and expand its export footprint, environmental compliance has become a central pillar of sustainable growth.
The ETP has been designed to meet the increasingly stringent environmental expectations of Western, European, and Far Eastern markets, where compliance with wastewater discharge standards, environmental reporting, and sustainability practices are essential for market access.
Future-Proofed Design for Scalable Growth
The facility has a base treatment capacity of 250 m³ per day, with the engineered capability to handle peak volumes of up to 325 m³, representing approximately 30% additional capacity to accommodate future growth in processing volumes. [ETP Opening | Word]
This future-ready design ensures that Pelwatte Dairy can maintain consistent environmental performance even under high production scenarios, reinforcing the company’s commitment to long-term compliance, operational resilience, and responsible expansion.
Advanced Technology Supporting Global Compliance
The ETP integrates advanced treatment technologies, including:
- Integrated Dissolved Air Flotation (IDAF)
- Anaerobic and Enhanced Sequential Batch Reactor (AnSBR/eSBR) systems
- Dedicated CIP wastewater management
- Real-time automated process monitoring
- Screw press sludge dewatering
These systems ensure high treatment efficiency and compliance with critical environmental parameters such as Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and nutrient discharge limits. [ETP Opening | Word]
