For printing, packaging, and textile printing enterprises, Ink sewage treatment machine is an indispensable core environmental protection equipment in daily production. Ink wastewater generated from water-based ink printing, ink mixing, equipment cleaning, and printing post-processing contains a large number of suspended ink particles, organic pigments, high-concentration COD, and colloidal impurities. If discharged directly without treatment, it will cause serious water pollution, violate international environmental discharge standards, and bring huge fines and production suspension risks to factories. Choosing the best ink sewage treatment machine is the key to solving ink wastewater pollution, realizing compliant discharge, and reducing enterprise operating costs. This article will elaborate on how to select a high-efficiency, energy-saving, and fully automatic ink sewage treatment machine, as well as the core advantages and industry value of our premium ink sewage treatment equipment.
1. Why Do You Need a Professional Ink Sewage Treatment Machine?
Ink wastewater is different from ordinary domestic sewage. It features high chroma, high COD, high viscosity, and stable colloidal structure. Ordinary sewage treatment equipment cannot effectively decompose and intercept fine ink particles, resulting in incomplete decolorization, unqualified water outlet, and easy equipment blockage. A professional ink sewage treatment machine is specially customized for the characteristics of printing ink wastewater, adopting targeted physical and chemical combined treatment processes to solve the pain points of difficult decolorization, unstable water quality, and high operating costs in ink wastewater treatment.
With the increasingly strict global environmental protection policies, industrial wastewater discharge standards are continuously upgraded. Traditional simple filtration equipment can no longer meet factory production needs. A high-quality ink sewage treatment machine can not only make the treated wastewater fully meet national and international discharge standards but also realize wastewater recycling, greatly saving factory water costs and creating dual benefits of environmental protection and economy for enterprises.
2. Core Standards for the Best Ink Sewage Treatment Machine
When purchasing an ink sewage treatment machine, many factory buyers only pay attention to the price and ignore the core performance indicators, leading to frequent equipment failures, poor treatment effect, and increased later maintenance costs. The best ink sewage treatment equipment must meet the following five core standards, which are also the key basis for Google users to screen high-quality ink sewage treatment machines:
2.1 Efficient Decolorization and Purification Capacity
The core purpose of ink sewage treatment is decolorization and COD reduction. The top-grade waste water treatment clear machine adopts multi-stage combined treatment processes including pre-sedimentation, automatic dosing coagulation, flotation separation, and deep oxidation. The decolorization rate can reach more than 98%, which can completely remove floating ink, suspended particles, and colored colloids in the wastewater. The treated water outlet is clear and transparent, with stable COD and SS indicators, fully compliant with industrial discharge and recycling standards.
2.2 Fully Automatic Intelligent Operation
The best ink sewage treatment machine is equipped with a mature PLC intelligent control system, realizing 24-hour unmanned automatic operation. The equipment can automatically adjust pH value, dosing amount, and aeration volume according to real-time water quality changes, avoiding manual operation errors. It is equipped with overload protection, blockage alarm, and automatic sludge discharge functions, which greatly reduces labor costs and operation thresholds. Even inexperienced workers can complete daily equipment management with one-key start and stop.
2.3 Energy-Saving and Low-Consumption Design
Excellent ink sewage treatment machine optimizes the internal structure and power system, adopting variable frequency energy-saving technology to adjust operating power in real time according to wastewater volume. Compared with traditional equipment, it reduces energy consumption by 30% or more. At the same time, the equipment has a high drug utilization rate, effectively saving the consumption of coagulants and decolorants, and the overall daily operating cost is extremely low, which is very suitable for long-term continuous operation of medium and large printing factories.
2.4 Integrated and Compact Structure
Most printing factories have limited workshop space. The high-quality integrated ink sewage treatment machine integrates sedimentation tank, reaction tank, flotation device, dosing system, and sludge pressing system into one unit, covering a small area and requiring no complex civil engineering construction. It can be put into use after simple pipeline connection, with short installation cycle and strong adaptability to various factory environments.
2.5 Durable and Low Maintenance
The whole machine of the premium ink sewage treatment machine is made of anti-corrosion carbon steel and stainless steel materials, which can resist the corrosion of chemical agents and ink wastewater for a long time. The core components are wear-resistant and durable, with low failure rate. The equipment is designed with a detachable structure, which is convenient for daily cleaning and maintenance, and the service life can reach more than 10 years, effectively reducing the factory’s equipment replacement cost.
3. Working Principle of Our Premium Ink Sewage Treatment Machine
Our ink sewage treatment machine adopts a mature and efficient physical-chemical combined treatment process, with stable and reliable treatment logic, which is suitable for all kinds of water-based ink, solvent-based ink wastewater treatment in printing and packaging industries. The whole treatment process is divided into four core stages:
First stage: Pre-treatment and impurity removal. The ink wastewater is pumped into the buffer tank, and large-particle impurities, residual paper scraps and floating sundries are removed through grille filtration and natural sedimentation, which avoids pipeline and equipment blockage and reduces the treatment pressure of subsequent processes.
Second stage: pH adjustment and coagulation reaction. The automatic dosing system precisely adds acid-base regulators to adjust the wastewater pH to the optimal reaction range of 6.0-9.0. Then, high-efficiency composite flocculants and decolorants are added to fully react with ink colloids and organic pollutants in the water, making tiny ink particles aggregate into large alum flocs.
Third stage: Flotation and solid-liquid separation. Through micro-bubble aeration technology, the aggregated ink flocs adhere to the bubble surface and float to the water surface, and the automatic slag scraping system cleans up ink sludge regularly. The settled fine impurities are discharged with the sludge system to realize thorough solid-liquid separation.
Fourth stage: Deep purification and recycling. After multi-stage filtration and deep oxidation treatment, the residual trace organic pollutants and chroma in the wastewater are completely removed. The treated clean water can be directly discharged up to standard or reused for workshop equipment cleaning, ink dilution and other production links, realizing zero discharge and water resource recycling.
