Textiles

Textile industry wastewater contains oils, lipids, salts and cellulose washed from cotton, wool and textiles, as well as various slurries, dyes, surfactants, auxiliaries, acids, alkalis and salts added during the processing, so the composition of this type of wastewater is complex and the various substances in the wastewater change rapidly.

BOC Sciences provides you with water treatment solutions for the textile industry. In addition to water treatment procedures, we can also provide solutions for physical and biological methods.

Water Treatment Solutions

Textile industry wastewater pollution management, first of all by transforming the process to reduce the amount of pollutants, and then in the use of the whole water processor for thorough filtration of dirt, followed by attention to the recycling of wastewater and materials.

Physical method

Physical method is mainly the use of the whole water processor for filtration, must be based on the raw materials used in the fabric, product varieties, processing methods, in particular, to understand the process of each process operation of adding chemicals, dyes, additives, analysis of the characteristics of wastewater components, through technical and economic comparison, the choice of the most advanced filtration treatment technology.

Biofilm method

The main categories of biofilm method are biofilter, bio-rotary, bio-contact oxidation, biofluidized bed and so on. Among them, the principle of aeration biofilm treatment is to use the oxidation and decomposition of microorganisms in the biofilm growing on the filter media in the reactor, the adsorption and retention of the filter and biofilm and the graded predation of the food chain formed along the direction of water flow and the denitrification of the internal environment of the biofilm and the anoxic environment. The main process features of the aeration biofilter include high impact load resistance, large treatment capacity, high decontamination capacity, high effluent quality, high oxygen utilization rate, short process flow, elimination of secondary sedimentation tank, low operating cost, fast start-up, and high environmental quality.

Water Treatment Procedure

Textile wastewater enters the collection pond through the pipeline to adjust the water quality, the water from the adjustment pond is lifted to the coagulation pond by the pump, PH adjustment is made by adding alkali in the pond to control the PH value at 7-9, then flocculant is added in the pond, and the wastewater enters the sedimentation pond after flocculation, the effluent enters the anaerobic pond to improve the biochemical properties of the wastewater, the effluent enters the contact oxidation pond/MBR pond, and the MBR treated water enters the intermediate pond for subsequent use The treated water after reverse osmosis membrane treatment is reused to the production line, the thick water produced is collected by the thick pool and then enters the intermediate pool, the sludge from the sedimentation tank is discharged into the sludge thickening tank regularly to concentrate and dewater through the equipment, the leachate from the filter press is returned to the regulating tank and re-entered into the system for treatment, and the mud cake after dewatering is transported out for treatment regularly.

Water Treatment Objectives

1. Protecting the environment is a key performance guideline for many major fashion brands, and the formation of groups such as ZDHC (Zero Discharge of Hazardous Chemicals) is a testament to the industry's commitment to corporate social responsibility.
2. Helping our clients meet ZDHC guidelines and avoid discharge fines and bad press is where we can help you. We also help them achieve their zero liquid discharge goals by achieving greater water reuse.
3. Achieving water recycling and reuse improves the overall water footprint to support environmental strategies and sustainable manufacturing production.
