Abstract
A portable, non-filtering, microorganism deactivation device for treating water contaminated with harmful bacteria such as E. coli and fecal coliform, includes a housing, said housing containing a high porosity media saturated with an ionically charged material such as colloidal silver.
Claims4
A method for deactivating water-borne pathogens in drinking water, comprising:
- placing 50 mL of distilled water and AgNO3 in a receptacle;
- adding 18 g of spherical zeolite particles to the receptacle, the zeolite particles having a diameter of 4.75 mm, a pore size of 10 angstroms, and a density of 689 grams per liter (43 pounds per cubic foot);
- letting the receptacle sit for no more than 60 minutes to obtain treated zeolite particles;
- removing the treated zeolite particles from the receptacle;
- allowing the resulting quantity of treated zeolite particles to dry;
- retaining the resulting quantity of the treated zeolite particles in a perforated cylindrical canister;
- obtaining a drink container with no more than 500 mL of drinking water, the drinking water contaminated with between 3,100 to 10,000 Colony Forming Counts (CFU) of E.coli per 100 mL;
- disposing the perforated cylinder canister within the drink container and stirring for no more than 30 seconds,
- thereby allowing the drinking water to flow through the perforated cylinder and thus around the treated zeolite particles, to deactivate the E.coli without filtering the E.coli from the drinking water;
- removing the perforated cylindrical canister from the drink container in no more than 30 seconds;
- and
- further resulting in deactivation of at least 99.9% of the E.coli in no more than 30 seconds.
