[Piping Magnetite Method Case Study] JR East South Nagasaki Housing

[Piping Magnetite Method Case Study] JR East South Nagasaki Housing

Is black rust really forming after the installation of The Bio Water? Proof of magnetite formation!

Here is an introduction to the case of JR East Japan Minami-Nagasaki Housing (Minami-Nagasaki, Toshima Ward, Tokyo). We conducted a demonstration of magnetite (black rust) formation using the "Piping Magnetite Method." After 14 months of installing The Bio Water, we quantitatively analyzed the rust components to determine if black rust had indeed formed. When the ratio of divalent iron to trivalent iron in the rust is 1:2, it can be classified as black rust (i.e., magnetite Fe3O4). As a result, the divalent iron was measured at 0.6 and the trivalent iron at 1.3, giving a ratio of approximately 1:2. Given that the component ratio is nearly 1:2, we can conclude that this rust is indeed black rust. [Case Overview] ■ Test Methods - Qualitative analysis of rust components in the water supply pipe using fluorescent X-ray analysis - Obstruction rate of the water supply pipe using a gamma-ray piping diagnostic device - Measurement of remaining wall thickness using an ultrasonic thickness gauge - Water quality testing (iron content testing / conducted 9 times) *For more details, please refer to the PDF document or feel free to contact us. *The section titled "Trigger for Interest" displayed during the PDF download is generated by the AI of Ipros Co., Ltd.

They are completely different! The difference between the "Piping Magnetite Method" and the "Magnetic Device."

They are completely different! The difference between the "Piping Magnetite Method" and the "Magnetic Device."

Thorough comparison of the advantages such as the elimination of the "magnetic field control every few years" that comes with magnetic devices, and the long-lasting effects of modified water!

■Construction Method 【Piping Magnetite Method】 Install BWΩ in the piping to modify the water passing through the device, converting red rust to black rust and repairing the deteriorated areas with black rust. 【Magnetic Method】 Install a magnetic device in the piping to increase the potential in areas that prevent iron from rusting. ■Construction 【Piping Magnetite Method】 Install at one location on the main water supply pipe. 【Magnetic Method】 Installation of the device is required every 50 meters. ■Maintenance 【Piping Magnetite Method】 No maintenance required. 【Magnetic Method】 The effectiveness weakens if the direction of the magnetic field is not changed every few years. ■Cost and Construction Period 【Piping Magnetite Method】 Particularly low cost compared to other methods, with a short construction period. 【Magnetic Method】 Lower cost and shorter construction period compared to other methods. ■Sustainability of Modified Water Effects 【Piping Magnetite Method】 Lab tests confirmed effects lasting 4 months, while field tests showed effects lasting up to 8 years. 【Magnetic Method】 Effects disappear in about 84 hours. ■Environmental Impact 【Piping Magnetite Method】 Becomes good water for domestic use, reducing the environmental burden of wastewater and other water-related issues. 【Magnetic Method】 No impact on the water environment. Additionally, comparisons with piping replacement work and lining methods are available in a PDF. For more details, please refer to the PDF document or feel free to contact us.

Seismic retrofitting method/device "e-Power Wall"

Seismic retrofitting method/device "e-Power Wall"

Protecting homes and families from earthquakes.

■ Construction can be carried out while living in the building for exterior wall reinforcement. ■ There is almost no demolition work, and it can be done at a low cost. ■ The construction method is simple, resulting in a short construction period. ■ It has excellent design qualities. (Finishing materials are flexible, such as siding, mortar, tiles, etc.) ■ Eligible construction methods for subsidies promoted by local governments.

Wall-forming machine TRD construction method machine

Wall-forming machine TRD construction method machine

Create high-quality soil-cement walls with uniform thickness and no wrapping defects!

The TRD method involves connecting a chainsaw-type cutter inserted into the ground to a base machine, performing horizontal excavation of grooves, injecting solidification liquid, and mixing and stirring with in-situ soil to create a continuous wall underground. It is applied for water-stopping walls in waste disposal sites, leakage prevention measures for river embankments, water-stopping walls for retention basins, or for inserting core materials such as H-beams, serving as a retaining water-stopping wall during underground excavation.
