Typical mechanized paper production involves two main processes: the treatment of raw material, which includes converting chip into pulp, washing and bleaching, refining, beating, sizing, coloring of the fibers, and later to form paper sheet in a Fourdrinier machine.
How does a pulp and paper mill work?
Gravity and suction is used in fourdriner to reduce the water content to nearly 70%. Hot press rolls squeeze out the water, and then the sheet travels though a large industrial dryer that finally reduces the water content close to 10%. Once out of the dryer, the pulp is cut, pressed, and packaged.

How does a paper mill work?
Basically, the paper mill produces paper from wooden chips or any other material contains fiber.

What is pulp and paper mill effluent?
The principal toxic components in pulp and paper mill effluents are resin acids and fatty acids naturally occurring in the wood pulped, and in effluents from bleaching processes toxic chlorinated compounds predominate.
What is paper formation?
Formation is a property of the sheet that is based on the overall uniformity of the fiber distribution in the sheet. Sheet formation is important because it affects both the appearance and the performance of paper and board products.
