The "DXNs-EP" is an electric dust collector designed to remove dioxins, with a discharge electrode placed at the center and pipe-shaped collection electrodes arranged in all directions, allowing discharge in all directions from the discharge electrode. Even if the distance between the electrodes changes due to hammering or other factors, stable discharge can be achieved by maintaining the distance between the electrodes plus an optimal clearance. This enables stable high current even at low voltage. Since there is no escape route for exhaust gases, even sub-micron particles are constantly attracted to the collection electrodes in all directions by Coulomb forces, allowing for high-efficiency dust collection. 【Features】 ■ Maintains stable high current values ■ Can remove water vapor and make exhaust gases transparent ■ Reduces dioxin emissions from exhaust gases without the need for slaked lime or activated carbon ■ Thin and compact ■ Economical *For more details, please contact us or download the catalog.

This catalog is a collection of case studies featuring our company's "Fluorine Immobilization Treatment of Gypsum," which has been researched for a long time by the Gypsum Board Recycling Research Association, focusing on the solidification of dihydrate gypsum and hemihydrate gypsum, as well as the immobilization of fluorine. We have conducted various leaching tests of fluorine using different immobilizing agents, but none have met environmental standards, particularly as dihydrate gypsum tends to be more difficult to immobilize than hemihydrate gypsum. However, by adding a small amount of the powdered fluorine immobilizing agent Super Magnecloze to dihydrate gypsum and stirring for just five minutes, we were able to achieve results that completely fell below the environmental standards in the fluorine leaching test. The process, along with examples of "Fluorine Removal" and the "FSC Method," is also included.

Until now, there have been very few methods to separate water from high-concentration bentonite wastewater using coagulants. With the combination of Ultra Separate BC and diluted hydrochloric acid, high-concentration bentonite wastewater can be easily treated. For dewatering, a cloth filter type simple dewatering machine is optimal. When treating bentonite wastewater with coagulation, it expands and contracts, creating strong additional resistance, making it impossible to process with conventional coagulation sedimentation equipment. Our company has developed a coagulation sedimentation device specifically for treating bentonite wastewater.

The leachate from the final disposal site contains a high amount of unburned carbon derived from organic matter and incineration ash, and often does not lose color even after the addition of coagulants. In such cases, the concentration of dioxins often does not decrease significantly. As a countermeasure, the Fe-DS system is effective. By using a combination of ferrous iron, caustic soda, and Ultra-Separate S-DS for coagulation, very clear treated water can be obtained. This treated water has a neutral pH and can meet the environmental standards for dioxins, including the river discharge standards. In examples of dioxin wastewater treatment, the concentration of dioxins can be reduced from 30 pg-TEQ/L to below 1 pg-TEQ/L after treatment.

A three-dimensional water flow stirring and sedimentation device that can achieve three-dimensional water flow stirring using a general stirrer has been patented! This is the first of its kind in the world. In general sedimentation, the coagulant dissolves and sedimentation occurs due to the rotational water flow generated by the stirrer's rotation. Most people feel that the stirring efficiency is weak when it is actually in operation. Three-dimensional water flow stirring involves using a standard stirrer to create a special structure in the tank, resulting in a circulation water flow where the center flows from top to bottom and the sides flow from bottom to top. By utilizing three-dimensional water flow, clear treated water and well-formed flocs can be obtained in a short time. We also offer consulting services for improving the stirring efficiency of your sedimentation device or developing a sedimentation device tailored to your needs, starting at 525,000 yen (including tax) per project.
