By using the DHSR system, high concentrations of dioxins can be reduced to below environmental standards.
Each coagulant exhibits high removal performance and coagulation performance, and the treated water meets the water quality environmental standards of the Dioxin Special Measures Law and the wastewater environmental standards related to harmful substances (seven heavy metal items). The treated water becomes remarkably clear.

basic information
The DHSR system is a system that can remove dioxins and heavy metals from wastewater simply by using dioxin removal coagulant Ultra Separate SDS, heavy metal removal coagulant Ultra Separate S300, and a dioxin removal device for coagulation treatment, allowing the purified treated water to be reused as washing water, etc.

Applications/Examples of results
In the case of dioxin treatment, the total dioxin concentration of 15,000 pg TEQ/L in the contaminated soil washing wastewater was reduced to 0.93 pg TEQ/L after treatment with the DHSR system, resulting in a dioxin removal rate of 99.993%, which is an excellent outcome. When the concentration of heavy metals is low, the Ultra Separate S-DS alone can meet the environmental standards, but in cases of high concentrations of heavy metals or when further purification of the treated water is desired, a combination is recommended.

Company information
Our company is small, but we have applied for patents for electric dust collectors and sludge solidification treatment devices. Currently, we are providing environmental purification technology consulting based on cutting-edge environmental purification technology, as well as developing and planning environmental purification devices. We have developed and are selling environmental purification products such as the dioxin removal coagulant Ultra Separate SDS, the heavy metal removal coagulant Ultra Separate S300, and the turbidity coagulant Ultra Separate MC, which is effective for a wide range of applications from organic wastewater to the purification of lake water quality. We are also currently selling a dihydrate gypsum semi-hydration device that can convert waste gypsum boards after crushing and separation into recyclable raw materials. We are developing solidifying agents for soil conditioners, high-moisture sludge, and sludge containing heavy metals, utilizing the semi-hydrated gypsum produced from the dihydrate gypsum semi-hydration device, and we plan to sell these as well. We intend to continue developing products and goods based on environmental purification technology in the future.
