This product is a device that uses steam (approximately 0.4Mpa) to heat from within a rotating drum, evaporating the waste liquid adhered to the surface of the drum body and 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 even when compared to industrial waste disposal costs. It also consistently demonstrates stable recovery effects for waste liquids containing valuable materials. 【Features】 ■ Instant drying that does not change the substance ■ The surface temperature of the drum is always constant, and the moisture content of the dried material is consistent ■ Work can be performed with indirect heating using steam ■ Low utility costs and 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 an anionic multivalent electrolyte, 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.
