"Eco Hard AII" is an environmentally friendly neutral solidifying agent with gypsum as its main component. It does not leach heavy metals such as hexavalent chromium, meets soil environmental standards, and can be used safely. There is no change in pH due to solidification treatment, so there is no adverse effect on the surrounding environment from rainwater and other sources. When mixed with sludge, a hydration reaction begins, and solidification occurs within 1 to 2 hours. It is also characterized by the ability to process quickly without the need for a curing process. Additionally, by using granulating materials to achieve solidification and granulation simultaneously, it is possible to impart moderate water retention and permeability to the treated soil, transforming it into soil suitable for vegetation. 【Features】 ■ Fast setting and hardening ■ Simultaneous solidification and granulation, providing moderate water retention and permeability to treated soil ■ pH remains the same as the original sludge! Transformed into soil optimal for vegetation ■ No fish toxicity in treated soil ■ Certain effectiveness on high-water-content clay and organic clay *For more details, please refer to the catalog.
