• Water treatment technology and systems

This product is a device that heats from within a rotating drum using steam (approximately 0.4 MPa) to evaporate the waste liquid adhered to the surface of the drum body, drying it to a solid powder state. There are various reasons for use, such as rising industrial waste disposal costs and the inability to discharge wastewater, but it shows sufficient advantages when compared to industrial waste disposal costs. It also consistently demonstrates stable recovery effects for waste liquids containing valuable materials. 【Features】 - Instant drying without changing the material - Constant surface temperature of the drum, consistent moisture content of the dried material - Work can be performed with indirect heating using steam - Low utility costs, short payback period - Fully automatic continuous unmanned operation, etc. *For more details, please download the PDF or feel free to contact us.

The "Nakaflock NF-100" is a coagulant that can dissolve in a short time compared to conventional coagulants, and it significantly improves sedimentation speed. In neutral or alkaline solutions of chemically treated wastewater, it becomes anionic polyvalent electrolytes, neutralizing the turbid solution of positively charged suspended particles. To form large flocs that settle quickly, it allows for a significant reduction in sedimentation time compared to conventional methods. 【Features】 ■ Quick dissolution ■ Coagulant specialized for heavy metal hydroxides ■ Easy-to-use one-pack ■ Simple disposal of empty containers *For more details, please download the PDF or feel free to contact us.
