Bleaching System

High-consistency hydrogen peroxide bleaching system

As a good chloride-free bleaching agent, hydrogen peroxide is used to bleach mechanical pulp, chemi-mechanical pulp and chemical pulp. Main equipment includes screw squeezer, heating screw, high-consistency mixer and high-consistency bleaching tower.

Features:

1. Less bleaching loss and strong technological adaptation;

2.Wastewater pollution load is low and easy to deal with.

3.High efficiency, less chemical dosage, full reaction and low residual rate of bleaching agent.

Applicable production scale: 50,000—100,000 tons/year
