Additionally, you can save measurement data from pH meters, ORP meters, etc., and analyze work conditions by graphing this data. 【Features】 - High-speed acceleration tank with a unique mechanism that does not use mechanical stirring, combined with a multi-stage inclined chamber that has a high separation effect for clear water and flocs. - Processing capacity more than three times that of conventional types. - High removal rate (over 80%) even with large fluctuations in SS turbidity. - Three-dimensional design structure allows for greater processing volume in the same area. - The sludge separated by sedimentation has a higher compression rate compared to conventional types. *For more details, please feel free to contact us.

This machine is our best-selling sand filter that consolidates our company's outstanding filtration technology since its founding, boasting a track record of delivering hundreds of units over the past 40 years, both domestically and internationally. We are now announcing a new specification, "NEW Auto Sand R," which further pursues improvements in processing capacity and stabilization of treated water quality. ● Thanks to a patented circuit, backwashing operation is performed automatically and reliably, allowing the filter media to be used permanently. ● It operates fully automatically regardless of fluctuations in raw water flow, ensuring consistent treated water quality and allowing for safe operation. ● The unit is compact, making installation easy and straightforward. ● An air backwash mechanism can be installed depending on the composition of the raw water quality. ● Particularly for wastewater from metal surface treatment plants, which often have unstable water quality and are difficult to treat, it can reliably filter trace heavy metal hydroxides and fine suspended solids, stabilizing the treated water quality below regulatory values. ● As a closed system device, it also demonstrates effectiveness when combined with pretreatment equipment such as COD removal, RO, and ion exchange.

The "EconoCross R," which combines high-precision membrane modules and a cross-free filtration method, is an MF membrane filtration device that replaces the traditional combination of coagulation sedimentation and sand filtration systems. ● It eliminates the need for coagulation sedimentation devices and sand filters, achieving separation, concentration, and ultra-precise filtration simultaneously. ● By not using chemicals such as coagulants, it reduces running costs and minimizes sludge volume. ● It maintains stable treated water quality that is not affected by fluctuations in raw water. ● It enables the recovery and reuse of valuable metals through systematic treatment of wastewater. ● It significantly reduces the maintenance work time for the equipment. ● It has a smaller installation area compared to conventional systems.

*It targets factory wastewater and similar. *The analysis methods comply with JIS K 0101 and JIS K 0102. *Please inquire about the fees for regular analyses and multi-sample analyses of the same items. *We also conduct various water treatment tests (wastewater treatment tests and filtration tests), so please inquire.

In general, removing trace amounts of heavy metals (especially hydroxide suspensions) and fine suspended particles to below regulatory levels is challenging, requiring either the introduction of highly efficient coagulation and sedimentation equipment or significant time for sedimentation. Particularly in the current situation where regulations on copper and zinc have been strengthened, it is not an exaggeration to say that most factories are struggling with countermeasures. This machine is a cutting-edge device that reliably captures trace amounts of heavy metal suspended substances in wastewater and stabilizes the treated water quality below regulatory levels. ● Due to the one-touch valve operation method, cumbersome valve operations during process switching such as filtration and backwashing are unnecessary. ● The filling filter media has a unique shape and three-dimensional arrangement, resulting in a greater capture of suspended substances compared to conventional filter layers. ● The specific gravity of the filling filter media is low, thus requiring less wash water during backwashing. Additionally, by using an air bubbling method, significant savings in wash water volume are possible. ● By adopting it as a component of the "Econo-Back System" (recovery and reuse system), the overall processing efficiency of the entire system is further improved.
