Purification Facility
Dedicated purification facilities process the highly concentrated and chemically complex liquid discharges generated during textile wet processing stages. An industrial wastewater treatment plant removes synthetic dyes, salts, and surfactants before the process water can be released to nature. This installation utilizes a combination of mechanical, chemical, and biological technologies tailored to the specific chemical load of the mill.
Operational Sequence
Coarse screening removes lint and loose fibers to prevent clogging in subsequent processing pumps. The wastewater then undergoes chemical coagulation and flocculation to precipitate suspended solids and disperse dye molecules. Aerobic biological treatment follows to digest the remaining dissolved organic matter.
Finally, settling basins or membrane filtration systems separate the purified water from the biological sludge.
Mill Integration
Dyeing and printing factories incorporate these facilities directly into their production cycles to secure their operating licenses. The treatment plant must handle fluctuating volumes and chemical loads depending on the fabric styles processed on a given day. Modern mills use automated monitoring to adjust chemical dosing in response to real-time changes in influent acidity.
Discharge Constraint
High energy consumption and chemical reagent costs represent major operating expenses for these treatment facilities. If the treatment system fails to meet local parameters, the factory faces heavy fines or complete closure.
