Stainless Build, Easy Maintenance

The 1-year warranty wedge fine Bar Screen protects pumps and downstream equipment by intercepting debris and preventing clogs with overload protection and multi-toothed rotary rakes for efficient, continuous cleaning. Its compact, low-profile wedge shape, durable stainless construction and automated control reduce maintenance while standard export carton packaging ensures safe, on‑time delivery. With short lead times (3–20 days), customizable channel widths, bar spacing and motor options, this Bar Screen adapts to your sewage plant needs to keep operations reliable and maintenance simple.

Here are six four-word subtitle options:

Backed by a 1-year warranty, this wedge fine Bar Screen uses a wedge-shaped bar rack with middle-mounted bars and a multi-toothed rotary rake to provide high-efficiency debris interception and reliable protection for downstream pumps and treatment processes. Its motor-driven variable-speed reducer, draught chain arrangement, overload-protection device and automatic flip-and-discharge gate enable continuous automated capture, lifting and dumping of sludge and floatables, with selectable bar spacings, channel depths and installation angles to match site requirements. Compact, robust construction with optional materials and control-box configurations ensures low-power, low-maintenance operation, easy integration into municipal or industrial sewage treatment plants, and consistently high throughput.

1-Year Warranty Wedge Screen

The QLHP wedge fine Bar Screen is a rotary toothed-harrow cleaner for sewage treatment plants, water supply facilities and pumping stations that intercepts and lifts debris while allowing wastewater to pass through its wedge-shaped bar gaps. Middle-mounted bars and a multi-toothed harrow, combined with overload protection, variable-speed drive and automated controls, ensure high cleaning efficiency, reliable operation and easy maintenance. Available in channel depths from 800 to 3000 mm with selectable bar spacings from 10–100 mm, 4 m/min rake speed and motor options from 0.75–3 kW, the Bar Screen can be customized for material, gate height and control box to suit project requirements.

Efficient Reliable Low-Maintenance Screening

Built by a specialist wastewater equipment brand and backed by a 1-year warranty, the Wedge Fine Bar Screen delivers rugged reliability for sewage treatment plants. Its wedge-shaped bars and fine spacing trap rags, hair, and grit while resisting blinding and enabling automated cleaning, corrosion-resistant materials, and energy-efficient operation. Features include stainless-steel construction, compact footprint, easy retrofit installation, and low power consumption—advantages that reduce downtime, lower operating costs, and extend service life.

Material introduction

The Wedge Fine Bar Screen features a corrosion-resistant construction using wedge wire bars made from stainless steel (commonly SS304 or SS316) to ensure precise screening and long service life in sewage environments. Its mainframe and support structure are fabricated from reinforced carbon steel with protective coatings or optional duplex stainless steel for aggressive conditions, while chains, rake teeth and fasteners use hardened or stainless alloys for wear and overload resistance. Seals, bearings and wear pads employ durable polymers and grease-lubricated components for smooth, low-maintenance automated operation backed by a 1-year warranty.

FAQ

What is a wedge fine bar screen used for in a sewage treatment plant?

A wedge fine bar screen is installed at the headworks or on-channel to remove coarse and fine solids — such as rags, hair, plastics, leaves and grit-bound particles — from incoming wastewater. By capturing these solids it protects downstream pumps, grit removal, biological reactors and mechanical equipment from clogging and damage, and improves overall plant performance.

What bar spacing or particle size can this screen handle?

Wedge bar screens are available with a range of bar spacings to suit different applications. Typical spacings for “fine” wedge screens are in the sub-millimetre to several millimetres range (for example 0.5–10 mm), but the exact spacing depends on the model and site requirements. Finer spacing increases solids capture but also increases headloss and cleaning needs, so spacing should be selected based on influent characteristics and hydraulic constraints.

How is the wedge fine bar screen installed and what should I consider for layout?

These screens can be installed vertically, inclined or at a slight angle in channels or at the inlet structure. Key considerations include sufficient upstream approach flow, structural support, access for inspection and maintenance, correct channel width and depth, and space for a discharge conveyor or washer/compactor if provided. Professional civil and mechanical integration with existing channel geometry and controls is recommended for reliable operation.

What are the routine operating and maintenance requirements?

Routine tasks include visual inspections, checking for blockages or excessive headloss, ensuring cleaning mechanisms (if automatic) function correctly, lubricating moving parts per the manual, and monitoring drive and electrical systems. Frequency depends on influent loading — high-load systems may need daily checks, lower-load systems weekly or monthly. Keep spare wear parts (seals, drive components, replacement wedge bars) on hand and follow the manufacturer’s maintenance schedule.

What does the 1-year warranty typically cover and what is excluded?

A one-year warranty generally covers defects in materials and workmanship under normal use and proper installation for 12 months from commissioning or delivery, per the supplier’s terms. It commonly excludes damage from improper installation, misuse, chemical attack beyond specified limits, lack of maintenance, accidental damage, modifications by third parties, and normal wear parts. Always review and register the warranty with the supplier and retain commissioning records to support claims.

Can the wedge fine bar screen be retrofitted into an existing sewage treatment plant and are customization options available?

Yes — wedge fine bar screens are commonly customized for retrofit projects. Options include different stainless steel grades or coatings for corrosion resistance, specific bar spacing, frame dimensions to fit existing channels, automatic cleaning and compaction systems, drives and control panels compatible with plant SCADA, and debris handling conveyors. Provide accurate channel dimensions, flow rates and influent solids characteristics to the manufacturer so they can propose a tailored solution.
