As the flexographic printing industry shifts toward green and low-carbon production, water-based flexo ink has completely replaced traditional solvent-based ink in most packaging, label, and paper printing fields thanks to its low volatility, non-toxicity, and low pollution advantages. However, the large volume of wastewater generated from plate cleaning, roller washing, and equipment flushing in daily production has become a major environmental challenge for printing enterprises. This kind of wastewater features high chroma, high COD, stable ink emulsion, and abundant suspended solids, which is difficult to degrade through natural precipitation. Improper treatment will not only cause serious water pollution and violate international environmental compliance standards but also bring huge fines and production suspension risks to factories. Our professional Water Based Flexo Ink Effluent Treatment Machine is tailor-made for the printing industry’s pain points, providing efficient, stable, and cost-effective one-stop wastewater purification solutions for flexo printing and ink printing enterprises.
Different from general industrial wastewater treatment equipment, our ink printing wastewater treatment machine is specially optimized for the physical and chemical characteristics of water-based flexo ink wastewater. Water-based flexo ink contains hydrophilic resin, pigment particles, additives and other components, forming a highly stable colloidal solution that is hard to clarify by conventional filtration methods. Relying on mature and upgraded integrated treatment technology of physical filtration + chemical coagulation + deep oxidation + precision filtration, our equipment effectively breaks the stable emulsion structure of ink wastewater, realizing thorough separation of ink pollutants and clean water. The whole treatment process covers multi-stage purification procedures including automatic grid filtration, homogeneous regulation, flocculation precipitation, hydrolysis acidification, and fine sand filtration, efficiently removing suspended solids, residual pigments, organic colloids, BOD, COD and harmful substances in the wastewater.
This wastewater treatment equipment boasts outstanding purification performance with industry-leading treatment indicators. Its decolorization rate reaches over 98%, completely eliminating the turbid and colored state of original ink wastewater. It can stably reduce COD and SS indicators to meet national and international industrial discharge standards, and the treated effluent is clear and transparent with stable water quality. Beyond standard discharge, the purified water can be directly reused for workshop equipment cleaning, plate washing and production auxiliary water, effectively reducing enterprise water consumption and realizingcircular water recycling. The concentrated sludge generated during the treatment process is small in output and easy to collect and process, avoiding secondary pollution and greatly lowering subsequent sludge disposal costs.
In terms of operational design, the high speed flexo ink printing wastewater treatment equipment fully considers the actual production needs of printing factories, achieving intelligent and low-cost operation. Adopting an integrated skid-mounted structure, the equipment features compact layout, small floor occupation, and flexible installation modes—available for both ground placement and buried installation, adapting to various factory site conditions. The whole system supports fully automatic intelligent operation, with automatic water intake, dosing, precipitation, filtration and backwashing functions. It requires no special personnel on duty, effectively saving labor costs for enterprises. Meanwhile, the optimized internal process structure reduces equipment operation energy consumption and wear and tear, with low noise and stable long-term operation, solving the problems of high energy consumption, frequent failure and complex maintenance of traditional treatment equipment.
Safety and compliance are core advantages of our equipment. In response to increasingly stringent global environmental regulations such as RoHS and REACH, the machine strictly follows industrial environmental protection standards in design and manufacturing. It can stably treat water-based flexo ink wastewater, adhesive wastewater and printing cleaning wastewater of different concentrations, with strong load adaptability and no water quality fluctuation during peak production periods. All core components are made of anti-corrosion and wear-resistant materials, adapting to the long-term erosion of ink chemical wastewater, extending equipment service life and reducing later maintenance and replacement costs.
Suitable for packaging printing, label flexo printing, carton printing and various ink printing production scenarios, our water-based flexo ink effluent treatment machine has helped numerous printing enterprises solve wastewater discharge and environmental compliance problems. It not only helps factories pass environmental inspections stably and avoid operational risks but also turns wastewater treatment from a cost burden into a profit point through water resource recycling. For printing enterprises pursuing green production, standardized operation and cost reduction, this efficient and reliable wastewater treatment equipment is an essential environmental protection weapon to empower sustainable industrial development.
Choose our flexographic printing sewage treatment equipment to achieve thorough purification of water-based flexo ink effluent, standard discharge and recycling utilization, and lead the new trend of green and low-carbon development in the printing industry with stable performance and cost-effective operation!
