BOEEP’s Stainless Steel Travelling Flow Band Fine Mesh Intake Screen delivers 80-97% filtration efficiency for primary wastewater treatment, cutting downstream maintenance costs by up to 50% and extending equipment lifespan. Built with durable SS304 stainless steel and a self-cleaning system, it is the ideal solution for facilities requiring reliable solid-liquid separation in challenging environments.
Trusted by 200+ Municipal & Industrial Facilities Worldwide
10+ Year Design Lifespan with SS304 Corrosion Resistance
Customizable for Channel Widths 950-2500mm & Depths 1-60m
Your Pain Point | Our Solution | Proven Results |
|---|---|---|
Downstream pumps/aerators frequently clog with fine fibers and debris | 1-6mm customizable fine mesh captures 97% of floating, settling and suspended solids | Reduces downstream process load by 97% |
Corrosive wastewater shortens equipment lifespan and increases maintenance | 100% food-grade SS304 stainless steel construction | Extends equipment life by 3x vs. carbon steel alternatives |
Limited installation space in urban facilities | Compact center-flow design with minimal head loss | Fits channels as narrow as 950mm without major retrofits |
High manual cleaning requirements and operational costs | Integrated self-cleaning nylon brush system | Cuts manual cleaning frequency by 80% |
Unreliable performance under heavy solid loads | Heavy-duty drive system with variable power options | Handles flow rates up to 81,000 m³/d |
As the critical first step in municipal and industrial wastewater pretreatment, our fine mesh intake screen sets a new standard for solid-liquid separation. Unlike traditional bar screens that only capture large debris, our fine mesh design intercepts even the smallest particles, fibers and organic matter that would otherwise damage downstream equipment.
Versatile Applications: River water intakes, water pumping stations, municipal wastewater plants, food & beverage processing facilities, chemical industries
Customizable Perforation: 1-6mm diameter options tailored to your specific wastewater composition
Continuous Operation: 24/7 uninterrupted performance with automatic debris discharge
Durability is non-negotiable in harsh wastewater environments. Our intake screen is constructed entirely from high-quality SS304 stainless steel, providing exceptional resistance to corrosion, rust and chemical degradation.
Self-Cleaning Mechanism: Integrated nylon brushes rotate continuously during operation, removing debris from the screen surface and depositing it into a collection bin. No shutdown required for routine cleaning.
Low Maintenance Design: Minimal moving parts and self-lubricating components reduce the need for frequent servicing
Long-Term Performance: 10+ year design lifespan with proper maintenance, backed by a 2-year warranty on all stainless steel components
Our patented center-flow design optimizes water distribution across the entire screen surface, maximizing filtration efficiency while minimizing head loss (<0.3m). This compact configuration makes it ideal for retrofitting existing facilities with limited space.
Modular Design: Pre-assembled units for fast installation and easy future expansion
Customizable Dimensions: Screen length (400-3000mm), discharge height (standard 1m, fully customizable), channel depth (1-60m)
Energy Efficient: Low power consumption (0.55-5.5kW total) reduces operational costs

Ideal for urban facilities with high daily flow rates and limited installation space. Our screens handle mixed domestic wastewater, capturing everything from plastic debris to fine hair and fibers. A municipal plant in Jiangsu, China reduced maintenance downtime by 42% and extended pump lifespan by 3 years after upgrading to NJKB-II screens.
Captures food scraps, starch particles, fruit peels and organic fibers that would otherwise clog membrane systems and damage pumps. Our SS304 construction complies with food contact safety standards, making it suitable for dairy, meat processing and beverage production facilities.
Resists corrosion from acidic and alkaline wastewater (pH 4-10), ensuring stable performance in harsh chemical environments. Ideal for chemical manufacturing, pharmaceutical production and textile dyeing facilities.
Removes floating debris, leaves, sediment and aquatic vegetation, protecting downstream pumping equipment from abrasion and clogging. Our screens can be customized for deep water intakes up to 60m.
Must be performed by qualified wastewater treatment engineers to ensure proper center-flow alignment
Pre-installation inspection: Verify channel dimensions, water depth, flow rate and electrical supply
Commissioning: 72-hour continuous operation test to confirm filtration efficiency, self-cleaning performance and system stability
BOEEP offers turnkey installation services worldwide
Frequency | Maintenance Task |
|---|---|
Daily | Check debris accumulation and activate self-cleaning system as needed; monitor flow rate and pressure |
Monthly | Inspect stainless steel components for signs of wear or corrosion; check brush condition |
Quarterly | Lubricate transmission parts; inspect motor and gearbox performance; clean flushing nozzles |
Annual | Full system inspection by BOEEP technicians; replace worn brushes and seals; calibrate sensors |
80-97%, depending on perforation diameter (1-6mm) and wastewater composition. Finer mesh delivers higher efficiency for fine particle separation, while larger perforations are suitable for high-flow applications with larger debris.
The integrated nylon brush system rotates continuously during operation, removing debris from the screen surface and discharging it to a collection bin. This eliminates the need for manual cleaning during routine operation and prevents screen clogging.
Yes. We offer full customization for all parameters, including screen length, channel width, discharge height, water depth and perforation diameter. Our engineering team will design a solution that fits your existing infrastructure perfectly.
