New, inexpensive method that significantly decreases textile effluent pollution has been developed by NIT Warangal.
In an effort to treat wastewater in the textile and apparel industry located in the Hanumakonda area of Telangana in an environmentally responsible manner, NIT Warangal, Prime Textiles, and IMPRINT have created a pilot-scale textile effluent treatment facility.
About Textile effluent
Pollutants include hazardous metals, dissolved solids, suspended particles, and colours are substantially present in textile effluent.
Total dissolved solids (TDS) should be the primary consideration in textile effluent.
Common salt and Glauber salt usage causes an increase in TDS in textile wastewater.
The direct discharge of textile effluents may raise the TDS concentration in both surface and ground water.
Water with TDS (high or low concentration) may change in flavour and cause aquatic creatures to swell or become dehydrated by disrupting the osmotic balance.
The salt content affects the irrigation water's quality. The water becomes contaminated and unfit for use in agriculture, industry, or home settings when the salt content rises.
About Research
In addition to providing a sustainable alternative to current treatment techniques, this ground-breaking technology has the enormous potential to turn hazardous wastewater into a beneficial source of irrigation for nearby agricultural areas.
A pilot-scale textile effluent treatment facility has been created by NIT Warangal employing biosurfactants (BS), cavitation (a process in which pressure changes in a liquid can quickly cause a great number of tiny cavities to form and subsequently implode-C), and membrane (M) technology.
The system effectively removes contaminants from the effluent by combining biosurfactants, cavitation, and membrane processes.
Coagulation is used to reduce the turbidity of suspended solids, biofilm development in MBBR reduces heavy metals and breaks down biodegradable pollutants, cavitation creates energy, and surface-modified membranes are used to effectively separate pollutants.
The pilot plant successfully processes the effluent for cleaning and agricultural use, with a capacity of 200 litres per day.
About IMPRINT (Impacting Research Innovation and Technology) India
It is a cooperative effort of the Indian Institutes of Technology (IITs) and the Indian Institute of Science (IISc), which was started in 2015.
Its objective is to advance research and innovation in ten technology-related fields that are important to India, including manufacturing, energy, and healthcare. Additionally, it seeks to lessen reliance on imported technology and gauge how research activities affect people's lives.
Process: The programme offers money and assistance for research initiatives that aim to solve significant engineering and technological problems.
