About Polydex: A Bacteriostatic Algaecide for Potable Water

POLYDEX is the result of extensive research to develop an environmentally responsible mineral-based bacteriostatic algaecide. This innovative formula uses natural minerals to provide excellent control of algae and suppression of bacteria in ponds, dugouts, lagoons, potable water storage tanks, etcetera.
POLYDEX provides a proprietary ionized mineral matrix, which effectively captures and carries copper ions (Cu++) evenly throughout a water environment and in greater concentrations and for longer periods than competitive copper based products. 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°C and 35°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 bacteria 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 micro-organisms 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 micro-organisms by oxidation. When POLYDEX is assimilated by specific micro-organisms, natural metabolic processes cease resulting in death of the organism.

Unlike copper sulphate, POLYDEX does not precipitate or stratify. It stays evenly dispersed in water over a longer period providing continuous protection from micro-organisms when proper concentrations are maintained. POLYDEX uses the most biologically active species of copper – but in minute quantities, to achieve cost-effective results from low application rates. Typically copper sulphate is effective only on the day it is applied and chelated copper products may be effective for up to 14 days whereas POLYDEX remains bio-available until assimilated by a micro-organism.

POLYDEX is registered under the PCP Act for use “in Municipal water supplies used as a source of potable water before it is purified for drinking purposes”.
