Water-based ink sewage treatment machine is a specialized ink sewage treatment equipment built for flexo printing, packaging printing and paper converting factories to tackle high COD and heavy color pollution from water-based ink cleaning wastewater. As packaging printing expands globally, water-based ink becomes the mainstream eco-friendly printing material, yet its washing wastewater contains acrylic resin, pigment particles and dissolved organic pollutants. This wastewater features high chemical oxygen demand, deep chroma and stable organic components, which are hard to purify with conventional sewage systems. Without proper ink sewage treatment equipment, factories face strict environmental penalties, discharge limit violations and damage to local water ecosystems. Our ink sewage treatment equipment delivers reliable COD and color reduction, helping printing plants meet emission standards and cut operational costs at the same time.
Water-based ink wastewater poses unique treatment challenges that ordinary wastewater machines cannot solve efficiently. The colored pigment molecules stay suspended or dissolved in water, creating persistent color; soluble resin components push up COD value sharply. Simple sedimentation or filtration only removes large suspended solids, leaving most dissolved organics and color intact. Many printing manufacturers tried basic treatment tanks but failed to pass environmental inspections, resulting in production shutdown risks. Our water-based ink sewage treatment machine integrates pH adjustment, coagulation-flocculation, solid-liquid separation and advanced decolorization modules in one compact unit. The whole ink sewage treatment equipment targets ink pollutants specifically, breaking down chromophoric groups and capturing organic substances that contribute to high COD. It achieves stable COD reduction and color removal continuously, suitable for small and medium flexo printers, corrugated box printing factories and paper tube production workshops.
What makes our waste water treatment clear machine stand out in the market is its consistent purification performance. Under normal working conditions, this water-based ink sewage treatment machine can reach 75%–90% color reduction and 60%–85% COD removal for typical water-based ink wastewater. After treatment, the effluent becomes clear, with greatly lowered organic load, complying with most industrial wastewater discharge regulations. For factories aiming for water reuse, we can add polishing filtration modules to recycle treated water for ink roller washing, reducing freshwater consumption and wastewater discharge volume. The system handles fluctuating water quality common in printing workshops. When ink concentration changes during shift production, the automatic dosing system adjusts reagent dosage in real time to maintain stable COD & color reduction results, avoiding sudden effluent index spikes.
Designed for printing shop environments, our water-based ink sewage treatment machine prioritizes easy operation and low maintenance. This ink sewage treatment equipment adopts fully automatic PLC control. Operators only need to start the system; the machine completes pH regulation, chemical dosing, flocculation reaction and sludge separation automatically. The human-machine interface displays real-time water quality data, tank level and equipment status. Operators receive alerts for reagent shortage or abnormal working conditions. The unit has a compact skid-mounted structure, requiring minimal floor space. Unlike large concrete wastewater pools, the integrated ink sewage treatment equipment can be installed indoors beside printing lines, saving construction investment and installation time. Sludge generated after ink purification concentrates automatically for easy collection and transportation, lowering sludge disposal expense compared with traditional wastewater treatment solutions.
Durability and running cost control are core advantages of our ink sewage treatment equipment. All liquid contact parts use anti-corrosion materials to resist long-term erosion from ink wastewater and treatment chemicals. The water-based ink sewage treatment machine runs with low power consumption and moderate chemical consumption. We optimize the coagulation and decolorization formula specially for water-based ink, preventing excessive chemical input that increases operating costs. Spare parts are standard and easy to source globally. Our engineering team provides full after-sales support, including on-site installation guidance, commissioning, operator training and regular remote technical service. Before order confirmation, we accept wastewater sample testing. We analyze your ink sewage sample, test COD and color removal performance, and customize the ink sewage treatment equipment configuration according to your daily water output and local discharge standards.
Sustainability and environmental compliance drive more printing enterprises to upgrade ink wastewater treatment systems. Regulators worldwide tighten limits on industrial wastewater COD and color. Packaging and flexo printing factories must invest in qualified ink sewage treatment equipment to maintain normal production. Our water-based ink sewage treatment machine is developed exactly for this demand. It not only removes color and reduces COD but also minimizes secondary pollution. Compared with advanced oxidation processes with high energy cost, our combined physical-chemical process balances purification effect and running expense, making it the cost-effective choice for packaging printers. Factories using this ink sewage treatment equipment can avoid fines, improve green factory credentials and enhance competitiveness in global B2B orders, where many buyers audit environmental compliance before cooperation.
The application scope of our ink sewage treatment equipment covers most water-based ink printing scenarios: flexographic printing on corrugated cartons, paper bag printing, paper tube printing, label printing and water-based ink mixing workshop wastewater. Whether your factory generates 1 ton or 50 tons of ink washing sewage per day, we can match the right water-based ink wastewater treatment clear machine capacity. For customers planning factory expansion, modular design allows later capacity expansion by adding reaction or filtration units without rebuilding the whole system. Many printing clients have installed our ink sewage treatment equipment and maintained stable COD & color reduction for years. Their effluent consistently meets local environmental standards, and they cut water bills and waste discharge fees significantly.
If your printing plant struggles with dark ink wastewater, high COD test results and environmental compliance pressure, our water-based ink sewage treatment machine is your reliable solution. As a professional manufacturer of ink sewage treatment equipment, we focus on solving real ink wastewater pain points for printing and packaging industries.
