Printing Ink and Textile Dyeing Wastewater Treatment Equipment

Professional Solution for High-Concentration Industrial Wastewater Treatment

Printing Ink and Textile Dyeing Wastewater Treatment Equipment is a specialized wastewater treatment system developed for treating high-colority, high-COD, and high-organic-content wastewater generated from textile dyeing, fabric printing, water-based ink production, packaging printing, pigment manufacturing, and related industries. The equipment effectively removes color, suspended solids, organic pollutants, pigments, dyes, and other contaminants, enabling wastewater to meet environmental discharge standards or water reuse requirements.

Designed with advanced treatment technologies and intelligent automation, the system provides stable performance, high treatment efficiency, and low operating costs. It is widely used in textile mills, garment dyeing plants, printing and packaging factories, ink manufacturing facilities, pigment production plants, and industrial wastewater treatment stations.

Working Principle

Printing ink wastewater and textile dyeing wastewater typically contain large amounts of dyes, pigments, resins, surfactants, suspended solids, and organic compounds, making them difficult to treat using conventional methods.

The wastewater first enters an equalization tank where water quality and flow are stabilized. It then undergoes pH adjustment, coagulation, flocculation, and sedimentation processes. Through the addition of specialized treatment chemicals, suspended particles, dyes, and pigments are aggregated into larger flocs that can be easily separated from the water.

Depending on treatment requirements, the system can be equipped with dissolved air flotation (DAF), biological treatment units, activated carbon adsorption systems, ultrafiltration (UF), nanofiltration (NF), or reverse osmosis (RO) technologies to further remove residual contaminants and achieve higher purification standards.
