NISSO develops and supplies ALM, which immobilizes toxic heavy metals contained in industrial wastewater and process liquids from plating plants, waste incineration plants, industrial waste disposal contractors, etc., bringing them to levels below wastewater standards.
Heavy metals strongly immobilized by ALM are flocculated by inorganic coagulants or polymeric coagulants, and coagulation separation is performed to remove heavy metals in order to make water safe for discharge or reuse.
ALM is cost-effective and contributes to the reduction of sludge volume after treatment. It is also characterized by the fact that it does not generate harmful hydrogen sulfide gas, making it safe to use in a variety of work environments.

In the field of waste disposal, Nippon Soda developed and provides HIDION, our heavy metal fixative highly effective in the treatment of fly ash from waste incineration. Approximately 34.2 million tons of waste is burned per year at waste incineration plants nationwide, and approximately 1.3 million tons of fly ash is released along with this burning. Insolubilization treatment is required by law for lead-based heavy metals contained in fly ash.
HIDION demonstrates a superior heavy metal fixative ability in this insolubilization treatment. It is used at many waste incineration plants nationwide and is highly valued.
