The "Wire Belt Screen" is a device that continuously captures and removes a large amount of floating debris and solid materials from flowing water in a short period of time. It excels as a dedicated leaf removal machine, enabling capture and separation that were insufficient with conventional products, thereby protecting generators and improving power generation efficiency. 【Features】 ■ High-speed processing with a screen passing flow rate of 2 m/sec ■ Supports high power generation efficiency with low power consumption ■ Efficiency improvement through simultaneous capture and removal operation ■ The main body and key components are finished in all stainless steel *For more details, please download the PDF or feel free to contact us.

The "Environmental Conservation Equipment Catalog" features products from Koyo Giken that are active in various water treatment sites. It includes a "Polymer Coagulant Dissolution Device" that continuously supplies powdered polymer coagulants, boasting over 7,000 units delivered, as well as a "Belt-Type Automatic Dust Removal Machine" that captures and removes suspended solids in flowing water. We propose a review of water process equipment from industrial water supply to wastewater, contributing to energy savings, cost reduction, and CO2 emissions reduction. *For more details, please download the PDF or feel free to contact us.

In agricultural irrigation, foreign objects (such as fallen leaves and debris) flowing into the water channels can cause clogging of pumps and sprinklers, potentially reducing irrigation efficiency. This can also lead to poor crop growth and decreased yields. Wire belt screens have been developed to address these issues. 【Usage Scenarios】 * Water intake from reservoirs * Water intake from rivers * Installation in irrigation channels 【Benefits of Implementation】 * Prevention of clogging in irrigation equipment * Stable water supply * Promotion of crop growth

Local governments and public facilities are promoting the use of renewable energy, and small hydropower generation is gaining attention as part of this initiative. However, generators installed in rivers and waterways face the challenge of reduced power generation efficiency due to debris and fallen leaves in the flowing water. Wire belt screens efficiently remove these solids, contributing to the protection of generators and the improvement of power generation efficiency. 【Usage Scenarios】 - Small hydropower plants in public facilities - Power generation in rivers and waterways - Water areas with a lot of fallen leaves and debris 【Benefits of Implementation】 - Improved power generation efficiency - Reduced risk of generator failure - Stable power supply
