Chlor Alkali Plant

For the development of the world soda industry, Daiso Engineering will address every need of industrial plant operators by utilizing its operational expertise on the electrolysis plant gained over the last ten (10) decades.

Daiso Co., Ltd. ("Daiso") is a pioneer company that operates chlor alkali plants in Japan (established in 1915). As a key member of Daiso's subsidiaries, Daiso Engineering has developed and owns a series of technologies implemented in electrolysis-, brine purification-, chlorine gas-, liquid chlorine-, and caustic soda plants.

Daiso owns four (4) chlor alkali plants in Japan, and Daiso Engineering designs and engineers chlor alkali- and other related plants based on various actual data collected from these operating chlor alkali plants, which ensures high credibility of its services.

Chlor Alkali Plant

Major Features
