Reliable Removal of Suspended Solids from Wastewater
with Clog-Resistant V-Shaped Wires
Wedge Wire Screen
This wastewater pretreatment screen features V-profile wedge wires that resist clogging. It removes debris (solids such as fibers and trash) and suspended solids (SS) upstream, helping prevent blockages and damage to downstream equipment such as pumps and sludge dewatering presses. Choose between the B Type, which offers automatic cleaning, and the S Type, which requires no electrical power. Manufactured by Ando Screen Co., Ltd.
Main Applications
- Industrial wastewater pretreatment (food processing, seafood processing, pig farming, etc.)
- Sludge thickening (wastewater treatment plants, human waste treatment plants, etc.)
- Classification and wastewater treatment (chemical industry)
- Raw material recovery (paper and pulp industries, etc.)
- Industrial wastewater pretreatment (textiles, leather, dyes, etc.)
Clog-Resistant, Strong and Lightweight Wedge Wire Screen
The slotted construction uses V-shaped stainless steel wires to reduce the risk of solids becoming lodged in the openings, helping prevent clogging. This reduces cleaning requirements and enables efficient solid-liquid separation. Its fully welded construction combines strength with low weight.
Slit width can be selected to suit the application for optimal treatment.
Wedge Wire Construction
Two Types to Suit Different Applications and Operating Needs
B Type | Automatic Backside Brush Cleaning
A rotary brush mounted behind the screen travels back and forth along the screen slits while rotating, automatically cleaning the screen to prevent clogging.
This helps reduce the effort required for routine cleaning.
With a drive power of just 0.1 kW, the backside rotary brush consumes little electricity, helping keep operating costs low.

S Type | Manually Rotatable Screen
The screen section can be manually rotated to expose the back of the screen for easy cleaning. Because no power is required, there are no electricity costs.

From Inquiry to Installation
Contact us to discuss your requirements. We will review conditions including wastewater flow rate; the type, size and quantity of solids present; available installation space; power availability; and equipment installed downstream of the screen. Based on your site conditions, we will recommend a suitable type (automatic cleaning or no-power operation), model and slit width. We will also consider how the removed screenings will be collected and provide a quotation once the specifications are finalized. After manufacturing and delivery, we conduct commissioning to confirm operation before handover.
You may wonder, “Can the machine dewatering the sludge as desired?” or “ Is it difficult to operate the machine?”
In addition to eliminating concerns before purchase, you can also use our products as a replacement machine during the service period of an existing dewatering machine or during the construction period of a wastewater treatment facility.
