Project overview
An oil and gas major needed a reliable pre-treatment solution to ensure high-quality feed water for critical operations, including RO and boiler systems.
Thermax implemented a high-capacity clarification and filtration system with integrated chemical dosing to handle high turbidity and suspended solids. The solution delivered consistent water quality, meeting stringent performance requirements and supporting efficient plant operations.
Challenges
- An oil and gas major required a robust pre-treatment solution to supply high-quality feed water for their RO plant, mixed bed system, and critical boiler and process operations. The raw water had high turbidity and suspended solids.
Solution
- Thermax designed, supplied, engineered, and commissioned a clarifier (2,200 m³/hr) and filtration system (2,040 m³/hr), supported by an integrated chemical dosing system. The design parameters addressed turbidity of 500 (nephelometric turbidity units) NTU and (total suspended solids) TSS of 500 ppm.
Result
- The system delivered <1 NTU turbidity and <1 ppm TSS, meeting the desired output quality. The project was successfully commissioned as per specifications.
