A "fresh approach"

to industrial water utilization


In today’s fast paced, competitive environment, industrial manufacturers need to react quickly and efficiently to changing marketplace conditions with an “out of the box” mentality. Those that don’t often find themselves falling behind their competitors in the rush for growth.
With limited resources, more and more manufacturers are realizing they cannot maintain the focus needed to operate their own production processes efficiently while also operating their utility and process water systems. Therefore, they are leaving the retrofit and/ or operation of these systems to trusted suppliers who can provide the quality and quantity of water they require to meet their changing needs in a safe, cost-effective and compliant manner.
Recognizing that clients across all industry segments and geographies are having to react to increasing costs for influent water and wastewater discharge, Veolia Water Technologies has developed an integrated approach to water management using their comprehensive technology and service portfolio.
By developing an overall understanding of a client’s water balance and its economics through their ‘‘ Best Practice Evaluation ’’, Veolia develops innovative water Conservation, Reclaim & Reuse programs to drive efficiency, reliability and overall cost reduction in the water systems they manage. The objectives of these integrated programs are quite simple:
  • To improve the utilization of waterin a client’s operation,
  • To minimize the amount of influent to and effluent from the facility, utilizing technology to reclaim and reuse water wherepossible,
  • To effectively minimize water problems related to scale, corrosion and fouling which might hamper production efficiency or reliability,
  • To minimize the client’s water footprint, reduce their environmental impact, and optimize their total costs of ownership related to the water they utilize.
At the foundation of an integrated Veolia Conservation, Reclaim & Reuse program are over 350 water treatment equipment technologies, a complete line of Hydrex® water treatment chemicals, and a bevy of consultative and on-site operational services. No matter what issues an individual plant may be facing, this comprehensive quiver of products and services allows Veolia to develop innovative and technically sound solutions for even the most demanding of industrial water applications.
Opportunities for manufacturers to improve and impact their water footprint can only be uncovered by first understanding the “True Costs of Water” and its utilization in their plant. This entails a detailed technical and economic audit of every water stream entering a plant, the water being used in a process, and the water being discharged back to the environment.
TCW Wave
Once the water balance at a plant has been outlined and documented, Veolia then develops a specific, prioritized summary of potential opportunities by applying its engineering resources to look at the water quantities and qualities as well as all treatment, production, environmental and manpower costs associated with it. This priority involves looking for improvements in the following areas:
  • CONSERVATION – Where can water utilization or performance results be improved, with the assistance of improved chemical treatment, standardized equipment technology, or on-site services?
  • REUSE – Where is water being either blended with other waste streams or discharged to wastewater treatment or to the municipal POTW where its quality can provide value back in the plant with little or no investment?
  • RECLAIM – Where are there large volumes of water being used and discharged, where an investment in technology could improve the water’s quality enough to be used in other applications and eliminate discharge?
Once the list of potential opportunities has been identified and discussed with the client, a full economic assessment is developed to include all factors that will influence the return on investment or payback each will provide the facility. The economic assessment will help to identify which projects stand out as the vital few that will have the largest impact.

Water has become a very precious commodity. The quality and quantity of available fresh water can influence where a production plant is located, due to the importance water plays in manufacturing processes. The proper utilization of this water can also influence a plant’s longterm reliability and efficiency. Only through a complete understanding of a plant’s water balance can a manufacturer be aware of water conservation, reclaim and reuse opportunities that can influence its top and bottom lines. At Veolia, this is our responsibility to our clients, which we call integrated water management. Some might just call it “A Fresh Approach.”

Case Studies
In one such example, a large Midwestern chemical manufacturer was dealing with changing river water quality to its plant, and could not develop a sustainable water plan to enable its 10-year growth plan.
Over an 18 month period, in 6 distinct project phases, Veolia utilized its Actiflo® mobile clarification technology, Filtraflo™ multimedia filtration technology, Sirion™ reverse osmosis technology, Hydrex® chemical treatment technology and Aquaservice™ on-site consultative engineering resources to help the client conserve, reclaim and reuse over 138M gal/yr, with an 11-month payback on its investment.
In another example, an automotive parts manufacturer was using reverse osmosis to pretreat water and heating it for use in cleaning its finished products. The water was then discharged and replaced with fresh city water.
Veolia retrofitted the process by simply installing a UFlex™ ultrafiltration unit on the discharge line from the process. By removing the high molecular weight solids from the discharge stream, it was able to be reclaimed and reused as makeup to the cleaning process. By recovering the water, which had already been processed through a reverse osmosis unit, and the BTUs contained in it, the payback on the UFlex™ unit, the Aquaservice™ operational contract and the Hydrex® chemical treatment program was 73 days!
