This plant will start up at partial capacity on 1 June 2007, and then build up to full-capacity operation by 1 November 2008.

Veolia Water Solutions & Technologies` subsidiaries, present in more than 50 countries, offer local support networks for their industrial and municipal customers. The geographical distribution of their revenue in North America is 8% with 6 different business units.

Water Treatment Chemicals

The 3 main goals of a WTC program

  • Improve or restore the performance
  • Protect the equipment
  • Reduce the operating expenses

Hydrex range

The Hydrex range of water treatment chemicals are used in the following areas

  • Clarifiers and filters (pre-treatment)
  • Reverse Osmosis and Ion Exchange systems
  • Cooling towers and boilers (utilities)
  • Process
  • Wastewater treatment

The Hydrex range is divided into two product families

  • Technical products
  • Speciality chemicals

Water Treatment Chemicals are an essential part of the Water Solutions offer, because they guarantee the reliability of the equipment, the process and are one of the significant service elements.

Applications

  • The water pH is sometimes adjusted to meet the operating specifications required by certain membranes or ion exchange resins. This is accomplished by adding caustic soda to raise the pH, or acid to reduce the pH.
  • Dispersants or scale inhibitors are sometimes added to prevent scaling caused by a concentration of specific ions in the water.
  • Oxidizing agents are used to prevent microbial growth.
  • Sequestering agents help prevent minerals such as calcium and magnesium from depositing on the surface of water systems, system piping and tanks.
  • Reducing agents, such as sodium sulphites, are added to neutralize oxidizing agents like ozone or chlorine, or to remove oxygen.

Water Recycle & Reuse

,

Water Recycling & Reuse for industries

Water is an essential production material for most industrial sites. In some industries, such as the microelectronics production, it is one the most significant expenses. Increasing droughts, floods, regulation, competition over abstraction, change the water availability and quality, and lead many industries to look for alternative resources.

Specific issues to consider for industrial sites

  • Ensure an uninterrupted and constant quality water supply, and avoid risks of plant shutdown due to water shortage
  • Reduce your cost of water consumption and wastewater management Integrate into future changes in local regulation and national policy
  • Take advantage of best practice and regulation such as the BREF
  • Improve your Corporate Responsibility report through the reduction of environmental impacts

Veolia Water Solutions & Technologies have proven experience of industrial water production through recycling, in most industries and provide adaptive and high performance technological solutions and associated services in the design, build and commissioning of water treatment plants.

Various configurations and cases

  • On-site water recycling
  • Cascade recycling of at the point-of-use
  • Reuse of treated municipal wastewater and storm water
  • Zero Liquid Discharge

Recycled water can respond to most industrial water needs from utility water (washing, cleaning, fire fighting, irrigation) to boiler feed water, process water and ultra-pure water.

Specific water treatment technologies and processes also respond to the diversity of industrial applications.

  • White water and condensates recycling in the Pulp & Paper industry
  • Recycling of produced water in the Oil & Gas industry
  • Loop-recycling of chemical baths
  • Rinsing baths, solutions, metal recovery

Main technologies and solutions for recycling and reuse

  • Suspended solids removal
  • Fine screening
  • Coagulation / Flocculation
  • Clarification
  • Filtration
  • Membrane Bio-reactors (MBR) : Aerobic treatment combined with membrane filtratrion
