Achieving Zero-Liquid Discharge at a Common Effluent Treatment Plant in India
Aria FLEX™ Custom Systems Case Study | Veerapandi CETP, India
The Veerapandi Common Effluent Treatment Plant (CETP) in the south of India chose Aria FLEX membrane filtration system from Aria Filtra™ to quickly meet government mandates to achieve zero-liquid discharge (ZLD) for industrial wastewater.
The challenge
Veerapandi CETP sought a new filtration system to help it meet a government mandate to achieve zero-liquid discharge (ZLD) for industrial wastewater. The plant, which treats wastewater from 72 textile factories in the region, needed to replace an existing two-year-old ultrafiltration system. To ensure more efficiency in cost, along with power and energy savings, Veerapandi CETP had to quickly identify and commission a more reliable filtration system.
The solution
After evaluating various solutions, the Veerapandi CETP team selected the Aria FLEX membrane filtration system from Aria Filtra to replace the existing system in its water treatment plant. The reputation of Aria Filtra’s performance led the Veerapandi team to begin discussions with Aria Filtra. Another driving factor was the strength of our membranes, which are capable of reliably treating feedwater with high total suspended solids (TSS) from various garment and textile factories and producing high-quality filtrate for reuse in the factories.
The results
As a part of Veerapandi CETP’s pretreatment system, our Aria FLEX unit enables the plant to successfully meet its requirements. Beyond providing quality pretreatment, our membrane system helps Veerapandi CETP operate at ZLD requirements, saving energy and money. The Aria FLEX system has been running for more than a year and continues its good performance—achieving more than 90% recovery compared to the recovery that Veerapandi CETP’s previous filtration system provided.
Solution overview
- Ability to meet the ZLD mandate
- Strong membranes that enable optimization and reduce strain on other equipment in the pretreatment process
- Significant energy and monetary savings because Aria FLEX protects reverse osmosis membranes and reduces the frequency of chemical cleaning
- An increase in plant capacity to 8 million liters per day (mld)
- Aria CARE™ service team to help optimize performance and conduct preventive maintenance
