Textile Wastewater Treatment Plant

stylish_lining

 

  • 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.
