Welldoing Paper Making sewage treatment machine is a purpose-built wastewater treatment solution designed exclusively for pulp mills, tissue paper factories, corrugated board plants, kraft paper production lines and all types of paper manufacturing workshops. As a professional manufacturer focusing on industrial water treatment, Welldoing has spent years optimizing the structure and process of our paper making sewage treatment machine to fit the special characteristics of papermaking effluent, which carries massive suspended paper fibers, lignin, cellulose, residual starch, high COD, BOD, SS and chroma. Our integrated papermaking sewage treatment system helps paper producers comply with strict local environmental discharge regulations, reduce sewage fines, and achieve high-rate water recycling inside the factory.
Papermaking is a highly water-intensive industry. A huge amount of wastewater is generated during pulp cooking, pulp washing, screening, bleaching, paper forming and paper pressing. If this sewage is discharged directly without professional treatment, fine fiber waste will block river channels, organic pollutants will consume dissolved oxygen in water bodies, and dark-colored effluent will bring irreversible harm to the surrounding ecological environment. Ordinary domestic wastewater treatment devices cannot handle this kind of high-concentration papermaking sewage well due to unstable treatment effect and easy clogging. That is why many paper mill owners choose a dedicated paper making sewage treatment machine instead of general wastewater equipment.
Our Welldoing paper making sewage treatment machine adopts a mature combined process flow, including fine screen pretreatment, fiber recovery tank, regulating tank, flocculation sedimentation tank, anaerobic reactor, aerobic biological treatment unit, secondary clarification and automatic sludge dewatering. The front-end fiber recovery module is one of our core advantages: it intercepts recyclable paper fibers from sewage, so these fibers can be sent back to the production line for reuse, bringing extra economic benefits while lowering the load of subsequent biochemical treatment. After anaerobic and aerobic degradation, most organic pollutants are broken down; flocculation and sedimentation further remove suspended solids and pigment, so the final outlet water becomes clear and stable.
Every paper making waste water treatment machine from Welldoing supports full customization. Our technical team will collect your actual water quality test data, daily sewage output, factory layout, local emission standards and water reuse demands before designing the whole set. Whether you own a small tissue paper workshop with limited space or a large integrated pulp and paper enterprise with thousands of tons of sewage per day, we can configure a suitable papermaking wastewater treatment system. Different from traditional concrete sewage pools that need long construction periods and occupy large land, our modular paper making sewage treatment machine is assembled in our factory in advance. It features compact layout, fast on-site installation, simple expansion and flexible relocation if your factory moves or expands production later.
Stable continuous operation is critical for paper mills, as most paper production lines run 24 hours a day. We select thick anti-corrosion carbon steel or stainless steel for the main body of our paper making sewage treatment machine, matched with durable water pumps, aerators, automatic dosing systems and online water quality monitoring sensors. The whole system can keep running nonstop with low failure rates. The operation is automated to a large extent: dosing, sludge scraping, water discharge and sludge conveying can run automatically, greatly cutting labor costs. Its overall power consumption is well controlled, which helps paper factories keep operating expenses low in the long run.
Treated clean water from our paper making sewage treatment machine can be recycled for pulp washing, machine showering, floor cleaning and auxiliary production links. This sharply reduces freshwater consumption and eases the pressure of water resource supply. The sludge separated in the treatment process will be delivered to the filter press and dewatered into low-moisture mud cakes. The mud cakes can be transported out for harmless disposal, incineration or comprehensive resource utilization. No secondary pollution will be produced if the system works normally.
Welldoing provides full-cycle one-stop service for every paper making sewage treatment machine project. Our service covers process simulation, drawing design, equipment manufacturing, factory pre-testing, container packing, overseas shipment, on-site installation guidance, commissioning, operator training and long-term after-sales maintenance. If you meet any operational trouble or need to upgrade your papermaking wastewater treatment system later, our engineering team can offer timely remote or on-site technical support.
If you are comparing reliable paper making Sewage treatment machine suppliers for your paper mill, or you plan to renovate your old papermaking sewage treatment system to meet updated environmental requirements, please send us your water quality and capacity information. Welldoing will prepare a customized technical plan and competitive quotation for your papermaking wastewater treatment project as soon as possible.
