Water Treatment and Sewage Treatment Pumping Solutions

Refinery and petrochemical plants require water treatment and sewage treatment systems to ensure proper handling of processed water and wastewater. These systems include filtration, chemical treatment, biological treatment, and discharge processes where pumps must handle both clean and contaminated water safely.

WILO pumps used in WTP and STP applications are designed to provide reliable flow for filtration units, chemical dosing systems, transfer lines, and discharge systems. Non-clog pumps and centrifugal pumps ensure smooth handling of wastewater, sludge, and treated water without blockage or performance loss. With strong experience in industrial water management projects, WILO provides complete pumping solutions including design, supply, installation, testing, and commissioning for refinery water treatment plants.
