Purity Systems Inc, in association with it’s Asia Pacific Distributors Ammtec Limited, offer complimentary conceptual capital and operating cost estimates as part of the comprehensive Purity Systems Inc. client support services.

Ammtec Limited ( www.ammtec.com.au ) is a worldwide recognized and respected metallurgical consultancy specializing in extractive metallurgy, hydrometallurgical research and treatment of environmental waste streams.

The process of obtaining a conceptual capital and operating cost estimate is as follows:

• The client provides Purity Systems Inc. a liquor analysis, flow rate and process objectives.
  
• This information is then forwarded, in confidence, to Ammtec Limited for evaluation.
  
• Ammtec Limited conducts a theoretical technical assessment based on in-house ion exchange models to predict resin suitability to the particular application.
  
• At this point if the Purity Systems Inc. ion exchange resins are thought not suitable for the particular client application then the client will be advised and no further work conducted.
  
• If the Purity Systems Inc. ion exchange resins are suitable for the client application then a conceptual capital cost estimate will be provided for a commercial ion exchange plant with the battery limit restricted to the ion exchange plant itself.
  
• Such conceptual capital cost estimates are supplied on the understanding that ion exchange resins may behave differently according to the process liquor being treated, specifically pH and elemental concentrations in a mixed metals environment. The theoretical models used to calculate selectivity, loading capacity, wash and rinse efficiencies may not adequately mirror the resin behavior in a mixed metals stream and as such the resin inventory determined from such modeling should be viewed as indicative only.
  
• Ammtec Limited will include, as part of the capital cost estimate, the cheapest capital equipment outcome on the ion exchange equipment for the particular application and may include technologies other then fixed beds, for example carrousels and other commercially proven technologies.
  
• Where it is determined that up-front treatment of the process liquor, for example by membranes, may reduce the total capital cost then Ammtec Limited will advise the client of such an outcome and will make recommendations and provide comparative capital and operating costs on these recommendations. In such cases the battery limit will be extended to include any such recommendations.
  
• In obtaining equipment quotations from third parties Ammtec Limited may release specific information on the client process to such parties and if so done Ammtec Limited will ensure through confidentiality deeds that all information supplied to third parties is held in confidence.
  
• At the completion of the capital and operating conceptual estimate a short report will be issued to the client for their review. If Ammtec Limited are aware that a cheaper non-ion exchange option may be available to achieve the client objectives Ammtec Limited will advise the client of the availability of such options.
