Zero Liquid Discharge (ZLD)

Robust industrial treatment minimizes wastewater discharge and maximizes water recovery.

Manage regulatory pressures and meet water reuse goals with an effective ZLD wastewater treatment plan

GE offers complete thermal and non-thermal ZLD solutions to manage tough-to-treat wastewaters. GE’s proprietary evaporators, brine concentrators, and crystallizers can help recover more than 95% of your plant’s wastewater while reducing the remaining brine as a product or solid.

Industrial Wastewater Evaporators

Wastewater management to meet strict regulations and overcome environmental concerns

GE’s wastewater evaporators turn waste into clean water that can be reused or stored for ongoing industrial or drilling operations. Whether as a central site or mobile application, GE’s brine concentration equipment is designed to help plants meet stringent discharge regulations by recycling untreated waters back into their processes. This allows industry to reduce the need to draw fresh water from lakes, rivers, or aquifers.

GE offers fixed and mobile evaporators.

Purify chemicals and recover pure salts from waste streams

GE’s specialized evaporative and crystallizer technology is designed for the unique needs of manufacturing and industrial processes. From concentrating caustic soda to recovering sodium chloride, GE’s pure product equipment can help you deliver. The advanced technology features falling film and forced circulation evaporators and crystallizers, controlled suspension crystallizers, draft tube baffle crystallizers, and steam driven as well as mechanical vapor compression systems.

Pure Product Concentrator and Crystallizer Features

GE’s advanced technology is designed to help you:

  • Generate valuable K2SO4 fertilizer from a salt mine
  • Concentrate caustic soda (NaOH) to 50 and 99% purity
  • Recover pure, saleable NaSO4 from a battery manufacturing facility
  • Reduce coal mine wastewater treatment costs by recovering pure NaCl which can be sold as road salt

GE's pure product evaporators and crystallizers specialize in pure salt crystallization:

  • Caustic (NaOH) concentration and flaking
  • Pure salts – NaCl, CaCl2, Na2SO4
  • Potash salts/fertilizers - K2SO4, KCl, K2CO3, KOH

Reduce wastewater streams to dry solids

In order to meet stringent zero liquid discharge (ZLD) requirements, environmentally conscience companies are turning to advanced technologies that eliminate wastewater streams and leave behind clean water and solid salt crystals.

Combined with other brine concentration technologies such as evaporators, crystallizers concentrate the wastewater to a solid that can be safely disposed of in a landfill or recovered as a valuable by-product for use.

ZLD Crystallizers Features:

GE’s patented produced water evaporators are effective in treating SAGD produced water as well as once-through steam generator (OTSG) blowdown.

  • Skid-mounted, fully packaged systems that include auxiliary equipment and controls for ease of installation
  • Designed to recover specific waste stream salts for valuable product recovery
  • Simple color graphic controls and an automatic wash system to ensure ease of operation
  • Minimal energy consumption with mechanical vapor recompression (MVR) technology for steam vapor recycling

Reduce fresh water intake by recycling up to 98% of your SAGD-produced water

GE offers a steam assisted gravity drainage (SAGD) produced water evaporator system with high on-stream availability that reduces downtime and is robust enough to handle upsets.

GE’s SAGD patented evaporator technology offers advantages in cost, reliability, and scheduling. By reducing capital spend and addressing environmental goals, GE’s team has built a vast number of successful SAGD evaporators over the last 15 years.

SAGD Produced Water Evaporator Features

GE’s patented produced water evaporators are effective in treating SAGD produced water as well as once-through steam generator (OTSG) blowdown.

  • GE pioneered a non-seeded approach for its produced water evaporators, thus reducing risk to the operating unit while still creating high quality distillate water
  • Evaporation versus warm-lime softening helps customers achieve 98% or more recovery, increasing reuse potential and limiting fresh water consumption
  • Robust design allows the evaporator to handle source water upsets
  • Maximize on-stream availability, which lowers overall operating costs and capital spend
  • Reduces or eliminates the need to draw fresh water from lakes, rivers, or aquifers
