Benefits of ZLD plant

Zero liquid discharge plant technology is growing globally as an important wastewater management strategy to reduce water pollution and extend water supply. The main benefits of ZLD are:

  • Minimizes wastewater discharge
  • Maximizes water recovery
  • Create a valuable product for sale
  • Removing environmental issues
  • Reduction of dependence on local water sources and local legislation

Lodz Denim Private Limited is well concerned with health and safety and therefore strictly adheres to safety norms in its premises. Its aims at being more and more innovative thinking and bring about the vibrant and dynamic approach in a paradigm change of a long-term nature. In line with the administrative controls that are necessary to ensure quality and promptness with which the service is to be delivered to the customer, a voluntary code of conduct will go a long way to secure the required commitment to the environment and Mother Nature.
The company has been set up a Multiple Effect Evaporator (MEE) plant, which is part of the project, and has been fully recycling the water used in the various production processes.

The plant is aimed to set an example for the protection of environmental norms and emerge as a role model for pollution control agencies like GPCB and CPCB.

Zero Liquid Discharge (ZLD) Plant

Zero Liquid Discharge (ZLD) is a water treatment process with a goal of recirculation of all of the possible water back to the process with zero liquid waste. The ultimate treatment process has zero or nearly zero impact on the environment.

Pre-treatment – reducing TSS, COD, Turbidity to filter out particle impurities or precipitation of sparingly soluble compounds to allow additional treatment.

Concentration of dissolved solids – by membrane technologies, either by a combination of reverse osmosis (RO) with electrodialysis (EDR). The way of concentrating RO brine by EDR. Or single step electrodialysis. Using these technologies to concentrate the stream we can achieve more than 98 % of recovery.

Thermal treatment – the last step is usually consisting of Evaporator/Crystallizer to generate solids. Final evaporation of remaining water for re-use together with precipitation of solid waste for disposal in a controlled landfill or to be sold as a valuable product (pure NaCl Na2SO4 etc.)
