Objective

In the pulp and paper industry and related paper recycling industry, large amount of wastewater is produced in the pulp and paper making process. In order to meet the requirements of both ecology and economy, recovering water from the effluent streams, the amount of fresh water used by the pulp and paper mill can be greatly reduced.

Solution

Sieve bend screens are the important parts of pulp and paper water treatment. The screen can remove debris, leaves, bark and twigs from wash waters to recirculation in woodyard plants, and recover loss fiber and improve the clarifier efficiency in pulp and paper mills.

Sieve bend screen has characteristics of firm in structure, good mechanical properties, high strength, rigidity and load capacity. For the section of profile wire is V shaped, the screen slot is narrow in the above and wide in the below, and thus be easy to leakage, wear and corrosion resistance, avoiding clogging and ensure smooth filtration.

Basic Principles

Sieve bend screen is a simple solid-liquid separation equipment, v type wire provides an efficient separation for the solids and the waste water, relying on centrifugal force and gravity of the water in the sieve bend screen, the solids are retained on the screen while the water is falling through.

Benefits

V type wire, non-clogging

No moving parts, low maintenance cost

Simple to install, self cleaning

Longer lifetime
