We will be exhibiting at the Rental Housing Fair 2021 in Osaka from October 14 (Thursday) to 15 (Friday), 2021.

By installing a water conditioning device, the red rust in the pipes changes to black rust, restoring the thickness of the degraded pipes!

The "Piping Magnetite Method" uses the water quality improvement device "The Bio Water" to convert red rust in water supply pipes into black rust (ferric oxide), aiming to extend the lifespan of the piping. The modified water forms a dense and continuous coating of calcium carbonate and other substances inside the pipes. As the red rust transforms into black rust, it repairs and restores the corroded areas of the deteriorated piping. Improvements in the blockage rate of the piping, as well as the prevention of leaks and red water occurrence, can be achieved at low cost and in a short construction period. Depending on the hardness, it is generally maintenance-free, thus reducing maintenance costs and efforts. 【Features】 ■ NETIS registration [KT-160125-A] ■ Installation involves simple construction at the water supply pipe's origin, with a short construction period of about half a day to one day ■ There is no need to replace pipes, allowing for low-cost measures against red rust ■ The effects are semi-permanent, enabling the use of water supply pipes for the lifespan of the building ■ Reduces BOD in wastewater, thereby lessening the environmental burden on water *From the download link below, you can view materials introducing the "Piping Magnetite Method" and the product catalog for "The Bio Water" all together. *The section titled "Trigger for Interest" displayed during the PDF download is generated by the AI of Ipros Co., Ltd.

Comparison with typical water supply pipe deterioration countermeasures! We introduce the duration of effectiveness and issues.

The "Piping Magnetite Method" involves installing BW in the water supply pipes, which slows down the oxidation rate, transforming red rust into black rust and repairing the deteriorated areas. This method is also applicable to leaking pipes and has a semi-permanent effect. The "Piping Replacement Work" provides an immediate and fundamental solution as the pipes become brand new, but it is very costly and generates a large amount of waste. The "Lining Method" damages the pipes, making a second application impossible. The "Magnetic Device Installation" has issues such as being ineffective at low flow rates. We also offer materials that cover all these topics. 【Features of the Piping Magnetite Method】 ■ Low cost and short construction period ■ Effects extend to drainage pipes ■ Improved cleaning power, antioxidant power, and antibacterial power ■ Effect measurement device allows for FS *For more details, please refer to the PDF materials or feel free to contact us. *The section "Trigger for Interest" displayed during the PDF download is generated by the AI of Ipros Co., Ltd.
