Hydroflow Electromagnetic Water Treatment Device [Overview Video]

Generate an electromagnetic field in water to achieve scale prevention, rust prevention, and slime suppression!

The radio frequency signal transmitted from the transmitter is used to create an electromagnetic field for water treatment inside the pipe, utilizing an electromagnetic field generation device and a ferrite ring fixed around the piping. The magnetic field is formed in a ring shape inside the pipe, perpendicular to the flow of water, while the electric field is formed radially from the center of the pipe towards the inner surface. The effective range extends 5,000 meters upstream and downstream from the installation location of the device.

[Useful Case] Delivery of iron and manganese removal equipment to a dog kennel.

Analysis conducted at the Water Quality Research Institute! A case where a suitable system was proposed after confirming the site.

We would like to introduce a case where we delivered iron and manganese removal equipment for a dog kennel. We received an inquiry from a customer stating, "We are using well water for animal husbandry, but we are troubled by the poor water quality." As a result of conducting water quality analysis at our water quality research institute, we found that the color, turbidity, iron, and manganese levels did not meet water quality standards. Therefore, we proposed our product (treatment capacity: 3000L/h), which was adopted. 【Case Overview】 ■ Installed Equipment: Iron and Manganese Removal Equipment ■ Inquiry Details: Using well water for animal husbandry, but the water quality is poor ■ Key Points - The installation site is coastal, raising concerns about salt damage, so we adopted a corrosion-resistant FRP filter. - We used a special filter material that enhances the removal capacity of iron and manganese. - The interior of the water tank was partitioned to separately establish oxidation and purification tanks, optimizing space. *For more details, please refer to the PDF document or feel free to contact us.

Pulse-type water treatment device "Vulcan" applied to agriculture

It is an environmentally friendly, salt-free solution for scale and corrosion.

Scale is a major issue for agriculture. The use of hard water leads to scale deposits that reduce the overall efficiency of the farm. This results in a significant loss of time, money, and vitality. Areas with scale deposits become ideal breeding grounds for recent proliferation and algae. As a result, this invites diseases and infections, hindering the growth of healthy animals. By using Bulcan, you can reduce scale deposits throughout the plumbing system. It also helps to lower operating costs and maintenance. The lifespan of fixtures and equipment is extended, and the time and effort spent on cleaning are reduced. There is little need for salt or chemicals, and the pH levels for corrosion remain unchanged. ● For more details, please download the catalog or contact us.
