Hydrosieve Screen Cuts WWTP Maintenance Costs by 90%

Country: Japan

Project: Municipal Wastewater Treatment Plant - Pretreatment Solid-Liquid Separation Upgrade

Technology: YUBO YSL1200 Hydrosieve Screen

The Challenge

A municipal wastewater treatment plant in Japan had a persistent headache—their influent was full of debris: gravel, twigs, plastic fragments, rotted leaves, you name it. The bar screens kept getting wrapped up and jammed, forcing maintenance crews to crawl under the equipment almost weekly. Monthly repair costs were exceeding ¥20,000 (approx. USD 2,000). What's worse, the debris that slipped through was wreaking havoc on downstream pump stations, damaging impellers and causing frequent shutdowns across the treatment train.

The Solution

The plant installed YUBO's YSL1200 Hydrosieve Screen. The system operates purely on gravity flow—no external power required. The wedge wire screen precisely captures large debris while the self-cleaning sloped design prevents clogging and minimizes maintenance needs.

The Results

Following the installation, the plant reported substantial improvements:

• Pump station clogging rate dropped by 60%

• Screen maintenance costs reduced by 90%

• Sludge volume in downstream settling tanks decreased by 25%, easing the load on the entire treatment process
