Pulp and Paper

Maximising Paper Production with Economic Water Usage

Water treatment is an integral part of operations in the pulp and paper industry. Inevitably, pulp and paper mills produce large volumes of wastewater containing high levels of Absorbable Organic Halides (AOX), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD). In addition to these contaminants, chemicals such as chlorine dioxide, sodium silicates and aluminium sulphate result in large quantities of water wasted and not meeting the requisite discharge standards.

Our Solution

Without any water recycling in the manufacturing process, the continual use of large quantities of process water is costly for any industry. As water and wastewater management experts, Hyflux can help the pulp and paper industry save cost by designing effective water solution systems that are efficient in their water usage while meeting the water qualities for manufacturing processes as well as discharge.

Raw Water Treatment

Water needs to be clarified to remove suspended solids and other small particles before entering the manufacturing facility as process water to ensure the end product is not affected by water quality.

Products and Systems

 

Wastewater treatment for Reuse/ Disposal

Contaminants in processed water differs depending on the type of raw materials. Moreover, during bleaching, colouring or decolouring of paper, it is critical for the wastewater treatment process to take place before water is discharged or reused back as process water.
 

Paper Recycling

Paper recycling is another important area in the industry. For paper recycling, pulp needs to be bleached to remove colours from old papers, thus generating wastewater. Also, additional stages of wastewater treatment are required to remove remaining particles before disposal.
