Project Name: Retrofit of Central-Flow Fine Screens at a Municipal WWTP

Year: 2024

Capacity: Total treatment capacity of 350,000 m³/d

Product Type: Central-Flow Fine Screens (Model: CFS200/1000/1200, 5mm super metal mesh panel)

 

Client Pain Points:

The original setup used 8 rotary drum fine screens with 5mm apertures, which proved inefficient and complex to maintain. These screens struggled to handle peak flow rates, caused excessive head loss, and incurred high operational costs.

 

Solution:

• Replaced 4 of the 8rotary drum screens with K.G.MATZEN Central-Flow Fine Screens, each handling up to 88,000 m³/d (≈1.02 m³/s), significantly boosting peak capacity.

• Lowered the channel floor by 600mm to adjust upstream water depth to 1.6m, ensuring optimal hydraulic performance.

• Introduced super metal mesh panel with a stainless-steel frame for enhanced corrosion resistance and cleaning performance.

• Optimized head loss across the system, maintaining a total head loss within 221.6mm, meeting design requirements.

• Integrated new auxiliary systems: 20 m³ stainless steel washwater tank, medium/high pressure pumps, ultrasonic level meters, and a compactor for fully automated operation.

 

Services Provided:

• Customized equipment design and manufacturing

• On-site installation guidance and technical support

• Supply and commissioning of auxiliary wash systems and automation control panel

• Interface planning for future capacity expansion

• Full lifecycle maintenance support

 

Project Outcomes:

• Four units of the new screens now fully meet daily 350,000 m³ flow under normal conditions.

• During peak flows (up to 455,000 m³/d), the system operates stably by running both the new and old screen sets in parallel.

• Maintenance was simplified, operational costs reduced, and overall reliability and service life significantly enhanced.
