POLYDEX is a unique solution containing electrostatically charged natural mineral ions. These ions attract and bond to negatively charged organisms stopping metabolism, causing death.POLYDEX is a sensible alternative to synthetic compounds that negatively impact our environment. Equally important these minerals are essential micronutrients to plants, livestock and humans.

Use POLYDEX in ponds, potable water tanks, lagoons, canals, dugouts, waterscapes, etc, in minute concentrations (1:30,000 to 1:600,000) depending on the application.

What does POLYDEX do?

POLYDEX works! It controls micro-organisms while being user safe and environmentally responsible (i.e.: safe with fish and frogs). Performance is guaranteed when used according to directions.

POLYDEX is selfmixing and does not evaporate or lose efficacy due to instability. The biological efficacy of POLYDEX remains to provide residual protection for extended periods. POLYDEX is consumed only in the process of killing target microorganisms in treated water. Unlike chlorine and other popular oxidants, POLYDEX is not affected by UV rays. 

POLYDEX is proven in municipal, agricultural and commercial applications where natural methods of biological protection of water are desired. Developers, hotel engineers, landscape and waterscape service companies, municipalities, livestock managers and farmers use POLYDEX to protect drinking, service and recreational water.

POLYDEX can maintain water lines, tanks and other containments free of algae, their toxins (which can effect color, taste and odour), suppress bacteria (including odour producing bacteria) as well as control biofilm and mineral scaling.

POLYDEX provides a proprietary ionized mineral matrix that effectively captures and carries copper ions (Cu++) evenly and in greater concentrations throughout a water environment for prolonged periods. Therefore control of micro-organisms is quicker, safer, less costly, and longer lasting under a wider variety of water conditions.

A British Columbia Research Corporation report on the bacteriostatic efficacy of POLYDEX against E.coli and Strep.faecalis , dated February 1993, concludes that, “In a hard water environment, the test results show that POLYDEX will be bacteriostatically active against the test organisms at temperatures of 20 o C and 35 o C, up to a dilution of 1:600,000 (0.1 mg Cu/L)”. In soft water dilutions must be somewhat less in order to achieve the same efficacy.

The Establishment Public Des Laboratoires Departmentaux, an independent testing laboratory in France tested and reported the bacteriostatic effectiveness of POLYDEX against 6 bacteria groups commonly used to evaluate drinking water quality using internationally recognized ISO test procedures. These tests confirmed that POLYDEX water treatment properly applied can reduce indicator bacteria (i.e. E.coli, Coliform, others) counts to zero.

In South Africa the University of Fort Hare concluded from a test program that the study gave conclusive evidence that POLYDEX is effective for the removal of indicator organisms ….. within the recommended limits of South African Water Quality Guidelines.

POLYDEX is registered by the Canadian Pest Management Regulatory Agency (an agency of Health Canada) as a bacteriostatic algaecide and Certified by NSF International per Standard 60 for use in drinking water.

POLYDEX is a user-friendly method of controlling microorganisms which can make humans ill or are commonly known to cause unsightliness, bad odor, and off taste in water storage containments, including potable water systems. NOTE: For algae control in ponds containing fish, consult EnvirEau for the proper fish-compatible application rates.

POLYDEX is a responsible product used for drinking water applications. Chlorine-based algaecides kill microorganisms by oxidation.  When POLYDEX is assimilated by specific microorganisms, natural metabolic processes cease resulting in death of the organism.

Opflow, Vol. 28, No. 3, March 2002 , a publication of the American Water Works Association, presented an informative article by Gayle Newcombe and David Cook. The focus was a cost comparison of different types of powdered activated carbon (PAC) as a method of removing fifty percent of MIB and geosmin from water in the treatment process of municipal water treatment plants.

The article describes the PAC treatment as a “steam activated coconut carbon, with a high level of activation” at a cost of $12,850 USD per 10 days dosing at 31 mg/L to reduce MIB from 20 to 10 mg/L concentrations in the process stream.

POLYDEX, a bacteriostatic algaecide, is less costly and more efficient than PAC for reducing algae-produced toxins and related odour, taste and colour.POLYDEX is a highly efficient, self-mixing liquid concentrate that stops algae in stored water. MIB and geosmin are compounds that are by-products of algae in water. POLYDEX kills algae and prevents its regrowth, thereby stopping MIB, geosmin, and any other algae-produced toxins and odourous gases at the source - in the water reservoir.

A testimonial regarding use of POLYDEX

Town of Oliver

The Town of Oliver owns and operates a 20 km long gravity, concrete lined canal that is one of the sources of water for irrigation and domestic water in this area. The growth of algae in the canal during mid summer when the water demand is high was the cause of numerous complaints from water users. Filters for irrigation systems, and screens for pump intakes were plugging up with algae as often as every 2 hours between cleanings. Normally at peak times 1 or 2 times a day cleaning the screens and intakes would be adequate, and a part of routine daily checks and maintenance.

After receiving approval from the Interior Health Authority for the use of Polydex in treating the water for algae, it was applied with a metering pump at a rate of 1 litre Polydex to 120,000 litres water for 1-1/2 hours. Test results from a point close to application to the end of the canal revealed a copper content in the water from .75 mg/L to .42 mg/L, below Canadian Drinking water Quality Guidelines, which allow up to 1.0 mg/L. Precautions were taken not to allow treated water to flow into fish bearing receiving waters.

Dramatically within a day almost all algae was gone or dying. Filters and screens had stopped plugging up with algae, and there were no more complaints from water users. For preventative measures an application a week later was done. No more algae have reappeared since applications 8 weeks ago. Polydex is the best product that we have ever used in treating algae growth; it has saved the Town labour costs and has delivered better quality water to our users.
