The Aqua Pure Water Treatment Technology System:

   Everything that goes around, comes around.

   In the past, efforts to develop large-scale distillation facilities have been, at best, only marginally successful, primarily due to the energy costs required to produce a finished product.

   The Aqua Pure System takes this old idea and revisits it with modern engineering, duplicating the important role distillation plays in nature. The Aqua Pure System's modular design means it can be tailored to satisfy a wide range of applications and treatments.

   Here, simply stated, is how the Aqua Pure System works. Wastewater is pumped in and suspended solids are immediately removed via sand filters. Water then flows through an initial heat exchanger, where the liquid temperature is to raised about 200 Deg. F.

   Prior to entering the evaporator, any non-condensable gases and V.O.C.s are separated from the water utilizing a flash tank. Once in the evaporator, the liquid is further heated to boiling, creating a head of saturated vapor.

   Mechanical vapor compression will now increase the temperature of the saturated vapor to approximately 225 Deg. F. The heated vapor returns to the condensing chamber to give up its latent heat of vaporization (via Aqua Pure's heat exchanger) to the incoming feed water. Concentrated inorganics and other foreign matter drop to the bottom of the evaporation chamber and are automatically removed for disposal.

   In the final stage of the process, the pure distillate moves back through the initial heat exchanger which transfers its acquired energy to the incoming waste water. The net result being a distillate that will pass the most stringent standards, with total energy loss not exceeding five percent.

The following is a summary of some of the more obvious applications:

   Wastewater Disposal

   Landfill leachate: At the present time there are numerous projects under way, especially in North America, to provide treatment of the leachate from various landfills to comply with environmental guidelines. These projects involve the remediation of existing sites as well as the construction of new landfill facilities. In recent years the protection of groundwater has become of major concern as the depletion of water resources continues.

   Hazardous wastes: There are various hazardous wastes generated by industry which at present require long-term storage or disposal at specialized facilities. Treatment of these wastes to reduce waste volumes can reduce storage, transportation and/or disposal costs significantly.

   Industrial wastes: Many industrial wastes are suitable for treatment by evaporation. In many cases the costs associated with disposal are extremely high because of the nature of the wastes and in some applications the use of evaporation could be cost-effective.

Potable and Process Water Production

   Seawater: The production of potable water from seawater is the most common application for evaporation technologies. There are many units in operation, especially on offshore applications, where portability and compactness are important.

   Brackish water: In many areas of the world the available groundwater supplies are not suitable for human consumption due to high dissolved mineral concentrations. In these cases distillation is normally a viable method of treatment and can be cost-effective.

   Process water: Various industries require process water supplies of varying qualities for different applications. Where distilled water quality is required the Mechanical Vapor Compression process can be cost-competitive with alternative technologies where energy costs are of concern.

   Wastewater recycling: Because virtually all contaminants are removed by the distillation process, various wastes, when distilled, are suitable for reuse, either as process, irrigation, or potable water. Where waste resources are limited or expensive, the Mechanical Vapor Compression process can result in significant cost savings by recycling the treated water. Recycling domestic sewage for reuse as potable water is a possible application for municipalities, camps, etc. with limited water supplies.

   Emergency units: The portability and compactness of vapor compression equipment make it suitable for the production of potable water in emergency situations (e.g.: floods, earthquakes, etc.) when normal water supplies become contaminated.

   A unit can operate as a stand alone module or can be paralleled as necessary to satisfy most throughput requirements. The 'unit' has the flexibility to operate from various power sources and can be readily adapted to portable service or augment, as necessary, existing less efficient equipment.

   Through our strategic alliance with Colt Engineering Corporation of Calgary (one of Canada's largest engineering companies) we can now offer a complete turn-key plant on a wide variety of water/waste water projects. Our unique process (patent pending) conceived in 1991 is continually evolving.

The Industry

   The water/waste water industry is a multifarious market that calls on numerous technologies to cope with an ever-increasing list of polluting contaminates in our environment. Distillation is a one step process that can remove the water molecule only, from a variety of pollutants in a solution, and subsequently produce a quality end product that no other process can match. These facts have been know to the industry for years, however, most attempts to produce a cost effective process have failed due to the high capital costs and energy required to produce a quality distillate.

   Aqua Pure's unique process addresses both of these concerns with confirmed efficiencies approaching 98% recovery of the energy used in the distillation process. This has resulted in energy costs that are only a fraction of a penny/gal for produced distillate. Capital costs are also very competitive with other processes due to its simplified process and small footprint (as compared to typical biological processes). The unit can be shop assembled with minimal on site infrastructure to build.

   The industries in general that Aqua Pure's process could operate in can be classified as follows:

Municipal process -

A) Water (salt, fresh or brackish for potable consumption),

B) Landfill Leachate (in compliance with the strictest Government regulations for discharge to the Environment).

C) Aquifer Regeneration (various waste waters can now be used for this purpose)

Treating Industrial Wastes - In the following fields-

A) Petrochemical - high volumes of water are produced and consumed in this industry, cost of treatment is becoming a very significant part of various processes.

B) Pulp and Paper - many plants in this field are considered serious polluters.

C) Mining - this industry creates huge tailing ponds, which require treatment prior to discharge into the environment.

D) Industrial Processes in General - many industrial processes rely on quality water for boiler feed, product washing and many other functions where water availability is key to staying in business or not.

The Aqua Pure Process

   The Aqua Pure technology (Patents Issued and Pending) process is a proven energy efficient method that will remediate wastewater containing high levels of total dissolved solids in a cost-effective manner.

Strategic Partner

   Colt Engineering Corporation, one of Canada’s largest engineering firms, has now taken over the engineering duties associated with the Aqua Pure Process. The Colt Companies also include a fabrication division (Cord Projects Ltd.) which allows Aqua Pure to provide a complete turn-key service for their customers.

Developments

   Aqua Pure has recently financed, managed and commissioned a 76,000 usgpd produced water desalination plant presently located in Bonneyville, Alberta. The APV unit is currently processing oil-produced water containing 45,000 parts per million of total dissolved solids, the distillate is then pumped out at a rate of 8m3/hr, this distillate is then used in a sand cleaning process as well as providing boiler feed water make-up.

Marketing    The Aqua Pure technology is currently marketing its technology in Canada, Poland and the United States. Several niches have been identified for the APV technology which has resulted in the Company preparing a total of eight proposals with a total approximate aggregate value of $53,000,000.
