Modern Water sells its largest-ever AMBC for Korea Salt Production Facility

Modern Water plc (AIM: MWG) is pleased to announce that it secured the sale of its largest by volume All-Membrane Brine Concentrator technology ("AMBC"), to be used in South Korea's first deep seawater salt production project. The plant will have capacity for treating approximately 13m3/h, concentrating sea water sourced from a depth of up to 600m. Salt production from seawater offers environmental benefits compared to land-based salt mining, which can result in environmental problems due to the waste it generates and the health hazards posed to salt miners.

The AMBC project will be executed by Modern Water, owner of leading technologies for water and wastewater treatment, in conjunction with its partner in China, Hangzhou Shangtuo Environmental Science and Technology Co., Ltd ("Sunup").

Simon Humphrey, CEO of Modern Water commented: "Our partnership with Sunup is capable of delivering our innovative technology directly to customers across China - and now also in Asian markets beyond China, such as South Korea. This is Modern Water's largest single AMBC plant yet and follows on from various successful plants we have designed with our partners in India and China."

Noah Tan, CEO of Sunup, added: "As the key process in this salt production project we will be using Modern Water's AMBC, the high saline modular concentration technology. AMBC allows our customers to achieve higher concentration levels than traditional membrane techniques and reduces the need for chemicals in salt production. AMBC is a step-change in efficiency, significantly reducing operating costs for our customers. It is also versatile and can be used across many different industries."
