TERI CBS Thought Leadership Webinar: ‘When Zero is the Ambition: the business case for ZLD in the Indian context’
18th July 2019 | 03:30-04:30 PM

TERI Council for Business Sustainability (TERI CBS) is delighted to host the next webinar in the series of 'Thought Leadership Webinar' for Indian companies and businesses.

The Central Pollution Control Board refers Zero Liquid Discharge (ZLD) to installation of facilities and system which will enable industrial effluent for absolute recycling of permeate and converting solute (dissolved organic and in-organic compounds/salts) into residue in the solid form by adopting method of concentration and thermal evaporation. ZLD will be recognized and certified based on two broad parameters that is, water consumption versus waste water re-used or recycled (permeate) and corresponding solids recovered (percent total dissolved /suspended solids in effluents).

Adoption of Zero Liquid Discharge system will be applicable to zero-down organic load, recover metals and other constituents. Success of ZLD involves treatment of different streams after knowing their nature, constitution, composition and compatibility. Implementation of Zero Liquid Discharge (ZLD) in all types of industrial sectors is gaining importance and in many sectors it is possible to achieve ZLD based on appropriate technology implementation.

The upcoming TERI- CBS Webinar will delve into the challenges and opportunities of implementing ZLD projects along with introduction of a TERI technology for Wastewater Treatment, which is novel, clean, green, sludge free, highly cost effective and enables ZLD.

Focus Issues

  • Does direct installation of ZLD facilities pose technical constraints to operate the specialized system?
  • What are the Technical Routes for Achieving ZLD?
  • How can Common Effluent Treatment Plants (CETPs) implement ZLD systems?
