"SPEX-M" is a product that can suppress the leaching of heavy metals contained in soil and drainage by incorporating them during the mineralization process of the material and binding them strongly. The layered clay minerals generated by the components present in the material and in the soil incorporate heavy metals into their structure, leading to their insolubilization. The heavy metal elements that can be insolubilized include arsenic, fluorine, lead, and cadmium. The range of application can be expanded by changing the lineup used according to the properties and characteristics of the heavy metals to be insolubilized (such as soil, drainage, pH, etc.) and the concentration of contamination. 【Product Details】 ■ Material pH: Approximately 9 (when suspended in water) ■ Usable pH: 5 to 11 (a post-treatment pH atmosphere of around 7 to 11 is desirable) ■ Specific gravity of powder: Approximately 0.8 to 1.5 ■ Appearance of powder: White fine powder ■ Main target elements: Arsenic, fluorine, lead, cadmium *For more details, please refer to the PDF document or feel free to contact us.

"SPEX-A" incorporates heavy metals contained in soil and wastewater during the mineralization process of materials, firmly binding them to suppress leaching. Additionally, since the solidification occurs in a neutral to alkaline environment, it is necessary to use a pH adjuster in acidic conditions. 【Features】 ■ Heavy metal elements that can be solidified: arsenic, fluorine, boron, lead, and cadmium ■ The range of application can be expanded by changing the SPEX-A used according to the properties and characteristics of the heavy metal solidification targets (soil, wastewater, pH, etc.) and contamination concentration. *For more details, please download the PDF or feel free to contact us.
