White Water Treatment

White Water Treatment, Reverse Formed Wedge Wire Screen for White Water Treatment, Internal Axial Wire Screen Pipes for White Water Treatment,Drum Screen for Pulp and Paper

Objective


In the pulp and paper industry, white water is a kind of wastewater from pulp and paper making process. In order to provide a clean source of reusable water that meets operational and ecological requirements, filtering white water to separate fibers and fines, while reduce fresh water demand and effluent volumes.


Solution


Wedge wire screen tubes are widely used for recovery fiber in white water treatment, the drum screen manufactured by wrapping and welding stainless steel V-shaped profile wire cylindrically around support rods under automatic specialized wedge wire screen machine. 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


White water flows into and distribute onto the sidewalls of the drum, internal helical baffle direct the liquid filtrate to a central drainage area, the liquid passing through the slot of screen, while solids are retained on the screen surface and transported to the open end of the drum.


Benefits


Removal of suspended solids

Recovery of fiber and fines

Reduced fresh water usage

Simple to install

Low maintenance cost

Longer lifetime

Stainless steel construction
