WASH BAY WASTEWATER RECYCLING FOR OILFIELD SERVICES EQUIPMENT DEPOT

BACKGROUND

Schlumberger, one of the world’s leading providers of technology for reservoir characterisation, drilling, production, and processing to the oil and gas industry, contacted MAK Water to design and manufacture a water recycling system for their new facility. Two separate equipment washbays, with differing waste streams, required two separately designed systems to achieve the strict treated water quality requirements.

A customised Dissolved Air Flotation (DAF) plant was required for the main equipment washbay and a customised Multimedia Filtration (MMF) plant was required for the pressure test bay. A high level of plant customisation, technical capabilities and experience was required to achieve the complex treated water quality requirements.
