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.

Solution

Custom design and manufacture of a 1,500 L/h skid mounted Dissolved Air Flotation (DAF) plant for the equipment washbay and a Multimedia Filtration (MMF) plant for the pressure test bay.
