Summary
Clean TeQ Water is currently delivering a 7,500 bbl/day HIROX® (High Recovery Reverse Osmosis) water treatment plant, to treat well water for well completions in the Middle East. Clean TeQ Water is working with it’s partner, NESR to deliver the plant for one of the big four oil companies.
The plant is designed to reduce the sulphate content of aquifer water to prevent scaling and damage to the reservoir. The HIROX® solution will achieve >90% water recovery, compared to around 30% recovery that would be achieved when using reverse osmosis alone. This results in a 60% reduction of water withdrawn from the scarce well and an 80% reduction of liquid waste.
The RO brine is used to regenerate the ion exchange resin in CIF® without requiring additional chemicals. A brine recovery circuit will also be included in the flowsheet to reuse the recovered salt, instead of adding imported salt, to achieve the targeted water density. This results in substantial operational cost savings and a reduction in carbon footprint for the end-user.
