The pulp and paper industry is one of the most water-intensive sectors in industrial production. Pulping, paper forming, bleaching and recycling generate wastewater with high COD, BOD, TSS, colour and calcium, with characteristics varying by raw material (OCC, virgin pulp) and product (Kraft, Testliner, Tissue). With over 20 years of experience, Cleantech has partnered with numerous paper mills across Vietnam through EPC, upgrade, O&M and water-reuse projects.
