This is an introduction to a case where our water treatment products were implemented at a recycling plant. The request was, "We want to clean the collected scrap aluminum and enhance its quality to increase its value," and "Is it possible to remove the dirt and odor from the aluminum, such as heavy oil?" By breaking down and deodorizing the oil and other substances in the scrap aluminum, we were able to improve the quality of the scrap aluminum and provide added value. [Case Study] ■ Recycling Plant ■ Request - We want to break down the attached oil and clean the scrap aluminum. ■ Implementation Effect - By breaking down and deodorizing the oil, we improved the quality of the scrap aluminum and provided added value. *For more details, please refer to the PDF document or feel free to contact us.

At the inorganic materials handling factory, there were challenges such as "wanting to proceed with production efficiently," "the plating solution itself is expensive, so it's a waste to dispose of it," and "wanting to reuse it, but the plating solution contains a large amount of particles like nickel, making the quality of the plating solution unstable." The de-drying process generates a clarified liquid with enhanced clarity through cake filtration and allows for the recovery of the cake as a dried powder. We can provide value through the recovery of raw materials, valuable substances, and waste reduction by drying the liquid and slurry in the manufacturing and reuse processes.

In the food service industry, there were challenges such as "the water used for washing cut vegetables is tap water, and the wastewater (muddy water) is directly discharged into the sewer...", "there are concerns about general bacteria and E. coli even for reuse", and "the environmental impact of discharging into the sewer is also a concern." The "ECO Clean" that has been introduced this time is a device in the area of precision filtration membranes (MF), which purifies the turbidity of the washing wastewater to the level of tap water. It reduces water bills, including wastewater recycling, and also lowers environmental impact. General bacteria are reduced to 1/50, and E. coli is not detected.
