Pulp & Paper Screening

Wedge wire screen can be manufactured to replace existing screens or improve separation throughput efficiency in numerous paper processing applications. This includes pressure screens for high and low separator pulp screening, fiber thickening and recovery, dewatering and effluent waste water treatment, cooker screens as well as black liquor drainers. We also manufacture static DSM screens (known as sieve bend screens) for the continuous and unattended separation of solids in several industries including food and beverage.

 

Sieve Bend and Flat Screens

Wedge wire screens are particularly well matched to the requirements of high capacity filtration. These screens are self-cleaning, durable and reusable. Sieve bend (or curve screens) have the wedge wires oriented perpendicular to the flow direction which allows water to be collected when passing through screen, then the angle and flow allows the solids or branches to slide over the screen’s smooth surface. These screens can be applied in water treatments, dewatering systems and other water-solid separation applications as well. Flat screen panels are used in similar application as sieve bend screens.

Dewatering screens are known as sieve bend or curved screens

Dewatering screens are also known as sieve bend or curved screens. Linker wedge wire type dewatering screens are designed to maximize capacity by using gravity and cross flow against the curved screen surface for removal of solids from a liquid process stream. Dewatering screens can be fabricated with most any slot opening, screen width or angle and are routinely mounted to a boxed style housing.

Applications for dewatering screens include wastewater treatment, sewage treatment, agriculture, mining and food wastewater processing.

Wedge wire screens are also particularly well matched to the requirements of high capacity filtration since they are self-cleaning, durable and reusable. Sieve bend (or curved) screens orient the wedge wires perpendicular to the flow direction which allows water to drop through screen and be collected as wastewater while the angle and flow forces the solids (or branches) to slide over the smooth screen.

This product is effective in wastewater treatment, dewatering systems and other similar solid separation applications as well. Flat screen panels are used in a similar application as sieve bend and in shakers for sewage separation systems.
