As global environmental regulations on industrial waste water become increasingly stringent, ink manufacturers around the world are facing unprecedented challenges in treating ink waste water, which is characterized by high chroma, high COD, high salt content and low biodegradability. To address this pain point and help ink enterprises comply with international emission standards while reducing operational costs, our company is proud to launch a cutting-edge green solution for ink waste water treatment, integrating advanced technology, energy conservation and resource recycling to empower the global ink industry’s green transformation.
Ink waste water, generated from resin synthesis, pigment processing, equipment cleaning and plate washing in the ink production and printing process, contains complex pollutants such as benzene series, acrylic compounds and heavy metals (chromium, zinc, etc.). Its direct discharge not only seriously pollutes water bodies but also exposes enterprises to severe penalties due to non-compliance with environmental standards. According to the latest international environmental regulations, including China’s GB standards for ink industrial pollutants and the U.S. Title 40 eCFR Part 447, ink enterprises must strictly control the discharge of COD, chroma and heavy metals, making efficient and eco-friendly waste water treatment an urgent need for the industry.
Our ink waste water treatment machine for ink waste water treatment breaks through the limitations of traditional treatment processes, which are prone to high sludge production, unstable water quality and high operation costs. Adopting the core route of “classified diversion, physical-chemical chain scission, biochemical efficiency enhancement and resource recycling”, the solution achieves efficient treatment and recycling of ink waste water through a scientific combination of multiple advanced technologies, bringing dual benefits of environmental protection and economy to enterprises.
The core advantages of our Ink sewage treatment machine are highlighted in three aspects:
First, High Efficiency & Compliance. The solution integrates iron-carbon microelectrolysis, three-phase fluidized Fenton and A/O-MBR technologies to break down macromolecular pollutants into degradable small molecules, increasing the B/C ratio from 0.08 to 0.35 and removing 50% of COD in the pretreatment stage. The subsequent low-pressure reverse osmosis process ensures that the treated water COD is stably below 50mg/L, chroma ≤10 times, and heavy metals such as chromium are not detected, fully meeting the strict requirements of international emission standards and helping enterprises avoid the risk of fines due to non-compliance.
Second, Energy Conservation & Cost Reduction. Compared with traditional treatment processes, our solution adopts low-temperature heat pump evaporation technology, whose energy consumption is only 1/3 of that of traditional evaporation. The whole system is fully automated, supporting real-time monitoring and intelligent early warning through mobile APP, which greatly reduces manual operation and maintenance costs. At the same time, 70% of the treated water can be reused for ink preparation and equipment cleaning, and the concentrated water can be converted into industrial-grade sodium sulfate through triple-effect evaporation for external sales, turning waste into treasure and reducing the enterprise’s water and raw material costs.
Third, Green & Sustainable. The solution uses non-toxic and environmentally friendly reagents, avoiding secondary pollution caused by chemical agents. It realizes more than 90% reduction of organic residues, and the whole treatment process is free of harmful gas emissions, helping enterprises achieve “zero discharge” of waste water and enhance their green brand image. This is in line with the global trend of low-carbon development and helps enterprises gain advantages in green supply chain audits.
Up to now, our waste water treatment clear machine for ink waste water treatment has been successfully applied in ink enterprises and printing factories in Europe, Southeast Asia, North America and other regions, including a leading book and periodical enterprise in East China and a cigarette packaging printing enterprise in South China. The projects have achieved remarkable results: the treated water meets the reuse standard, the enterprise’s annual sewage discharge fee is reduced by 30%, and the additional profits brought by green certification and order expansion are considerable. The solution has won wide recognition from customers for its stable performance, high efficiency and cost-effectiveness.
We firmly believe that with our professional technology, high-quality service and innovative concept, our ink wastewater treatment clear machine for ink waste water treatment will become the preferred choice for global ink enterprises to achieve green production, and work together with partners around the world to promote the ink industry towards a more environmentally friendly, low-carbon and sustainable future.
