Effluent Treatment Plant for Textile Industry

The textile industry is one of the most water-consuming industries and also generates a large amount of wastewater. Textile production processes release toxic chemicals, dyes, and starches into the water. This sector generates effluent of diverse compositions that could cause significant water pollution, threatening human health and environmental damage. This is why limiting hazardous wastewater discharge from the textile industry is mandatory by setting up an effluent treatment plant. ETP plants play a pivotal role in the textile industry. It is a multi-step treatment system designed to effectively treat textile effluents generated using manufacturing processes. In this blog, we discuss the importance of effluent treatment plants for the textile industry, highlighting their role in helping companies comply with environmental regulations and safeguard public health. 

Sources & Processes that Generate Textile Effluents 

Textile production involves wet and dry processes. In the wet process, clean portable water is used, releasing wastewater that needs to be treated before disposing of. The main cause of the generation of textile effluents is the use of large volumes of water in chemical processing, dyeing, printing, bleaching, mercerizing, and finishing. 

Ravi Enviro Industries Private Limited is one of the industry-leading ETP manufacturers in India. We provide efficient ETP plants for the textile industry. Powered by MBBR technology for unparalleled results to help textile manufacturing companies effectively treat wastewater and comply with environmental regulations. 

Importance of Effluent Treatment Plant for Textile Industry 

ETP plants are the most effective wastewater treatment systems, and they are designed to treat effluent from different industrial establishments like the textile sector. Apart from effluent from wet processing procedures, textile facilities also generate wastewater from other processes. This includes humidification in spinning, cooling water from towers, steam generation from boiler feed water, softener plants, ion exchange, and other wet processes. ETP plants eliminate the contaminants and improve water quality on an accepted standard for safe disposal. 

Benefits of ETP Plants in Textile Facilities 

• Environmental Protection: Textile effluents like dyes, chemicals, and other contaminants are treated that could otherwise cause a negative impact on human health and the environment. 
• Regulatory Compliance: By employing effluent treatment plants, textile facilities comply with environmental regulations regarding wastewater discharge to avoid penalties & legal scrutiny. 
• Preserving Resources:  Treating effluent water allows for the reuse of precious water, reducing the reliance on freshwater sources.

ETP Plant Process for Textile Industry 

• Screening & Pretreatment

Raw effluent wastewater from the textile production process goes first through screening to get rid of large debris and solid particles. After that, the pretreatment process takes place, where processes like sedimentation and equalization are used to adjust pH levels and remove suspended solids. 

• Primary Treatment 

In this stage, the wastewater enters the primary tank for a prolonged period of time for the heavier particles to settle down at the bottom and the lighter particles to float above. The floated and settled particles are removed using flocculation and coagulation and passed to the secondary treatment process. 

• Secondary Treatment 

Following primary treatment, the effluent water enters the secondary treatment, where the biological process takes place. Aerobics and anaerobic reactors foster the growth of microorganisms that break down organic pollutants, minimizing the BOD (biochemical oxygen demand) and COD (chemical oxygen demand). 

• Tertiary Treatment 

In the tertiary treatment stage, advanced treatment technologies and processes like filtration, membrane separation, and chemical coagulation are used to eliminate residual solids, dissolved solids,  colourants, and other effluents. 

Before disposal, the treated effluent wastewater undergoes disinfection using UV radiation, chlorination, and ozonation. After treatment, the wastewater is ready for safe disposal.  As one of the most renowned effluent treatment plant suppliers in India, we design ETP plants with consideration of the textile industry’s needs.
