Zero Liquid Discharge (ZLD) Plant in India
Sustainable and Energy-Efficient ZLD Systems
GPT provides complete system and solutions for ZLD. We are a water and wastewater treatment plant manufacturer and supplier providing advanced brine minimisation solutions for various industries.
Our proprietary Sustainable Brine Shrinker (SBS©) system based on hybrid Forward Osmosis Membrane (FO) technology is an advanced membrane-based system that effectively treats and recycles complex industrial wastewater for Zero Liquid Discharge (ZLD) applications.
We can custom-build and provide ZLD plant of capacities ranging from 5 to 500 m3/day capacity capable of treating high TDS, high COD and high turbidity wastewater effectively.
Conventional thermal technologies such as multi-stage evaporator (MEE) and crystallization system often require high capital investment, expensive equipment setup and increased operation and maintenance (O&M) costs.
The SBS© system offers economical and sustainable alternative over traditional route and it helps to achieve reduction in evaporation and drying load.
GPT has developed patented SBS© system offering multiple benefits. SBS© has been tested successfully and implemented commercially for effluent treatment plant in India in various industries.
Advantages of SBS©
- 70% water recovery
- >13% concentrate TDS
- excellent salt rejection with <1000 ppm of product water TDS
- 8 to 12 kWh/m3 of energy consumption
- 50% reduction in O&M costs and 30% reduction in capital investment due to reduced load on evaporator/dryer system
- less chemical use
- integrated and modular structure
GPT's typical ZLD system will consist of:
- Primary treatment
- Secondary treatment system involving advanced Membrane Bioreactor (MBR Technology)
- Optional Reverse Osmosis (RO) system to achieve desired brine concentration
- Forward Osmosis membrane system for tertiary treatment and enhanced brine recovery
- Compact and downsized evaporator/dryer system
