How SWA Water’s Large Flow Oil Separators Create Cleaner Industrial Wastewater & Exceed Environmental Compliance!
When it comes to industrial wastewater management or treatment, managing large volumes & high flowrates of oily water is a significant challenge. That’s where SWA Water’s Large Flow Oil Separators come into play. These robust systems are designed to efficiently remove oil and other free hydrocarbons from high-volume wastewater streams, ensuring environmental compliance and operational efficiency.
What are Large Flow Oil Separators?
Essentially, these separators utilise gravity and the principles of Stokes’ Law to separate oil from water. They’re engineered to handle substantial flow rates, making them ideal for industries like oil and gas, mining, and heavy manufacturing. The design typically incorporates coalescing plate packs, which enhance the coalescence of oil droplets, facilitating their separation from the water phase.
Key Benefits of SWA Water’s Large Flow Oil Separators:
⦁ High Flow Rate Capacity: Designed to handle large volumes of wastewater, ensuring efficient treatment even in demanding industrial settings. This can be single units to 1,000 m3/h.
⦁ Efficient Oil Removal: Utilises CPI technology for effective separation of free and dispersed oils, resulting in cleaner effluent, often achieving <1mg/l of oil in the treated water.
⦁ Environmental Compliance: Helps industries meet stringent environmental regulations by reducing oil discharge into waterways.
⦁ Reduced Operational Costs: Efficient separation minimises the need for further treatment, reducing overall operating expenses.
⦁ Durable and Reliable: Constructed with high-quality materials to withstand harsh industrial environments, ensuring long-term reliability.
⦁ Customisable Solutions: SWA Water can tailor these systems to meet the specific requirements of each client, including flow rates, oil concentrations, and site conditions.
How They Work:
⦁ Wastewater Inlet: Oily wastewater enters the separator.
⦁ CPI Separation: The SWA coalescing plate packs promote the coalescence of oil droplets into larger oil droplets. The larger the oil droplet size, the faster the oil separates from the water phase.
⦁ Oil Collection: Separated oil rises to the surface and is collected.
⦁ Clean Water Discharge: Treated water is discharged, meeting regulatory standards.
These separators are essential for industries that produce large volumes of oily wastewater. By investing in SWA Water’s Large Flow Oil Separators, businesses can ensure environmental compliance, reduce operational costs, and promote sustainable practices. Their robust design and customisable options make them a valuable asset for any industrial operation dealing with oily wastewater.
3 Case Studies
1. PTTGC/TTCL (Thailand): SPH Central Booster Compression Project
⦁ Challenge: PTTGC, in collaboration with TTCL, required a robust wastewater treatment solution for their LNG production plant in Northern Thailand. The project demanded efficient oil separation from a high-volume wastewater stream to meet strict environmental standards.
⦁ Solution: SWA Water supplied a 324 m³/h CPI Large Flow Oil Separator which included 6 plate packs inside of the separator, effectively removing oil and hydrocarbons.
⦁ Outcome: The project was successfully completed, ensuring environmental compliance and contributing to the plant’s operational efficiency. The reliable performance of the SWA Water Large Flow Oil Separator met the demanding requirements of the LNG facility.
2. KLIA (Kuala Lumpur International Airport, Terminal T2): Wastewater Treatment Plants
⦁ Challenge: Kuala Lumpur International Airport (KLIA) needed to install a wastewater treatment system to handle potentially oil (aviation fuel) contaminated stormwater and ensure compliance with environmental regulations. The system needed to treat oily wastewater from aircraft hard stand areas.
⦁ Solution: SWA Water designed and supplied a custom Large Flow Oil Separator system consisting of 10 x oil separator sites, 18 oil separator units and 59 plate packs, tailored to KLIA’s specific flow rates and effluent requirements for a combined flowrate of 61,000 m3/h.
⦁ Outcome: The system easily met and exceeded environmental standards. This ensured the airport’s operations were environmentally sound, and protected the surrounding ecosystems.
3. IRPC Power Station, Rayong, Thailand: Effluent Treatment Optimisation
⦁ Challenge: IRPC developed a power station to provide electricity for its industrial estate development CHP 11 at Rayong, Thailand. IRPC sought to optimise its effluent treatment process to reduce oil and hydrocarbon discharge.
⦁ Solution: SWA Water provided two (2) 120 m3/h double-skinned below ground Large Oil Separators, integrated into Toyo’s existing treatment infrastructure
⦁ Outcome: The implementation of SWA Water’s Large Flow Oil Separator resulted in a substantial reduction in oil and hydrocarbon levels in the plant’s discharge. This optimisation improved compliance with environmental regulations and enhanced the plant’s overall sustainability.
