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.

The "Net Belt Screen (Safety Filter)" is a safety device suitable for the removal of SS in drainage. It features a sloped screen section with a horizontally extended screen in the upstream waterway. This design ensures that when the water depth in the waterway is shallow, only a portion of the lower end of the screen belt is submerged, reducing the filtration area and significantly decreasing the flow rate, thus resolving traditional issues. Additionally, the screen belt uses a special plastic mesh belt, allowing for the hygienic removal of not only conventional debris but also fish waste, fish scales, and shell fragments in fishery research facilities and fishing ports. 【Features】 - Suitable for SS removal - Sloped screen section with a horizontally extended screen in the upstream waterway - Resolves traditional issues of reduced filtration area and significantly decreased flow rate - Screen belt made of a special plastic mesh belt - Capable of removing fish waste, fish scales, and shell fragments in fishery research facilities and fishing ports *For more details, please refer to the PDF document or feel free to contact us.

In urban wastewater treatment facilities, efficient sludge management is required. In particular, it is important to automate a series of tasks such as the removal of solids captured by screens, dewatering, and storage, in order to reduce the burden of maintenance. Improper treatment can lead to decreased operational efficiency of the facility and may cause odors and environmental pollution. Our "Belt Conveyor Type Continuous Automatic Screen (with Sludge Dewatering Machine)" addresses these challenges and achieves efficient sludge management. 【Usage Scenarios】 - Urban wastewater treatment facilities - Sludge dewatering processes - Automation of solid removal, dewatering, and storage 【Benefits of Implementation】 - Increased efficiency in sludge management - Easier maintenance - Improved operational efficiency of the facility

In wastewater treatment plants and intermediate pump stations, the removal of debris during inflow is required. In particular, the removal of debris captured by screens is important. Improper handling can reduce operational efficiency due to issues such as pump clogging. Additionally, human waste should not be stirred up, which improves hygiene maintenance. Our "Belt-Driven Continuous Automatic Screen (with Dewatering Machine)" addresses these challenges and enables efficient facility management. By equipping the device with a dewatering machine, we can also achieve weight reduction during debris collection. 【Usage Scenarios】 - Small-scale wastewater treatment facilities - Sewage intermediate pump stations - Automation of solid removal, dewatering, and storage 【Benefits of Implementation】 - Improved efficiency of debris collection - Easier maintenance management - Enhanced operational efficiency and hygiene of the facility
