Asahi Kasei's Microza Hollow-Fiber Membrane Selected For Desalination Plant In Kuwait

the company’s largest order for water filtration membranes

TOKYO--() - Microza™ hollow-fiber membrane for water treatment from Asahi Kasei was selected as pretreatment membrane for the Doha Phase 1 reverse osmosis (RO)1 seawater desalination plant to be built near Kuwait City by Doosan Heavy Industries and Construction, a major Korean plant construction company.

The Asahi Kasei membrane treatment capacity for this project is scheduled to be 610,000 tons per day, representing the largest hollow-fiber filtration membrane order received by Asahi Kasei.

Many RO plants for seawater desalination are planned in Kuwait and other countries of the Middle East to address chronic shortages of fresh water, with microfiltration (MF) and ultrafiltration (UF) membranes including Asahi Kasei’s Microza™ being adopted as pretreatment membrane.

In addition to being widely used around the world in the fields of potable water production, wastewater treatment, and water recycling, Microza™ has a growing track record as pretreatment membrane for RO in the Middle East. Microza™ was selected for the Doha Phase 1 Plant in recognition of its outstanding performance and reliable operation, and Asahi Kasei will actively continue to focus on meeting growing demand in the Middle East.
