Junyi Filtration’s Customized Filtration System Successfully Supports Cooling Water Impurity Removal Project at Japanese Customer’s Factory

Recently, Shanghai Junyi Filtration Equipment Co., Ltd.’s customized sponge filtration system was successfully delivered to Fujii Kogyo Co., Ltd. (Katsumata Kogyo Ltd.), a customer enterprise in Shizuoka Prefecture, Japan, and has been successfully applied to the pretreatment process of factory well water intake and production cooling water impurity removal, providing reliable solid-liquid separation assurance for the stable, safe, and long-term operation of the customer’s production equipment.

Project Background

It is understood that this Japanese customer is mainly engaged in the production and processing of factory equipment supporting components. The cooling water and circulating water for production equipment in the plant area are all supplied by local groundwater extraction. The raw water contains fine sediment and suspended solid impurities over the long term. As the equipment continues to operate, impurities easily adhere to the interior of pipelines and cooling equipment, causing problems such as pipeline blockage, reduced heat exchange efficiency of equipment, and wear and aging of mechanical parts, directly affecting the stable operation of the production line and the service life of the equipment. In response to the on-site water quality conditions and production requirements, the customer urgently needed a dedicated filtration device that adapts to Japanese pipeline standards, has precise filtration accuracy, operates stably, and is free from frequent maintenance.

Customized Solution

Based on the actual on-site working conditions of the customer and the requirements of Japanese industrial equipment specifications, the Junyi Filtration technical team tailored a JIS 80A standard flange sponge filter solution for the customer.

  • Material: The equipment as a whole is made of 304 stainless steel, which is corrosion-resistant and rust-resistant, suitable for the humid groundwater working conditions of the plant area and long-term outdoor and indoor pipeline use environments.

  • Filtration Precision: The equipment is equipped with a 100μm high-precision sponge filter element, which can precisely intercept fine sediment, solid particles, and other impurities in the water, effectively purifying the cooling water quality and completely solving the equipment failure problems caused by impurities in the water.

  • Standard Compliance: At the same time, the equipment is fully designed in accordance with Japanese JIS pipeline standards, with precise dimensions and strong sealing performance, perfectly adapting to the customer’s existing on-site pipelines without the need to modify on-site equipment, greatly reducing the customer’s modification and use costs.

Quality Control & Project Execution

During the project communication process, the customer had extremely strict requirements for equipment standards, structural craftsmanship, sealing performance, and factory inspection. Our technical team provided one-on-one support throughout the entire process, repeatedly verifying equipment drawings, flange parameters, filter element structure, inlet and outlet layout, and installation dimensions, and carried out multiple optimizations for key indicators such as equipment pressure resistance, leakage prevention, and material compliance.

Before the equipment left the factory, the company strictly implemented multiple quality inspection processes such as hydrostatic pressure testing, sealing testing, and dimension verification to comprehensively ensure that equipment quality meets Japanese industrial acceptance standards. For this project, the customer purchased a total of two filter main units and also ordered spare filter elements, fully meeting the needs of long-term continuous operation of the equipment and daily maintenance.

Significance & Future Outlook

The successful implementation of this Japanese cooling water impurity removal project is another important practice of Junyi Filtration in the overseas industrial water treatment field, further confirming the reliability and professionalism of the company’s non-standard customized filtration equipment.

Relying on mature R&D design and production manufacturing capabilities, Junyi Filtration can adapt to industrial standards of many countries around the world such as JIS, ANSI, and DIN, and can customize various high-precision filtration systems for different complex working conditions such as chemical fluids, new lithium battery materials, industrial circulating water, groundwater treatment, and mineral purification. In the future, Junyi Filtration will continue to deeply cultivate the global industrial filtration market, continuously optimize products and solutions, and provide more professional, more efficient, and more stable filtration supporting services for customers at home and abroad.
