Wastewater Treatment - Zero Liquid Discharge (ZLD)
Zero Liquid Discharge is a process that is beneficial to industrial and municipal organizations as well  as the environment because money is being saved and no effluent, or discharge, is left over.  ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced. Siemens provides equipment for industrial and municipal plants to effectively reuse their wastewater effluent in order to achieve zero liquid discharge.

ZLD systems provide numerous economic and environmental advantages for plant managers—water is recycled and reused, saving on the cost and treatment of raw water.
Since all water is reclaimed, no effluent is discharged from the plant, avoiding the cost of environmental impact. The technology is particularly  appropriate in water-short areas.

Siemens has world-leading experience in supplying and installing ZLD systems. Our technologies include:

  • Biological treatment
  •  Physical treatment
  •  Filtration
  •  Membranes
  •  Disinfection

Siemens also provides pilot treatment systems and analytical testing to document the efficacy of treatment prior to installation. We also provide parts and service on all of our equipment, as well as equipment which may have been provided by other manufacturers.

 Water/Resource Recovery, Recycle, Reuse & Zero Liquid Discharge

Case Study: Zero Liquid Discharge Results in Recycling Success

High costs and declining reserves make water a valuable resource in Mexico. International Truck and Engine Corporation’s 1,080,000-sq. ft. assembly plant in Escobedo, Nuevo Leon, Mexico, is located in the middle of Mexico’s northern desert.  The plant requires several thousand gallons per day (gpd) of water to produce more than 200 medium and heavy trucks daily.  Using fresh water would place an inefficient cost burden on the plant while simultaneously straining the rapidly dwindling local drinking water supply.  Moreover, local discharge limits prohibited International from disposing of concentrated waste streams such as RO rejects and acid and caustic streams in local waterways
