Abstract

Methods and systems for enhancing of quality of liquid by treating a source liquid to enhance the concentration of low zeta potential crystals and produce a treated liquid having a higher concentration of low zeta potential crystals than that of the source liquid. The inventive system comprises an aqueous liquid source having a threshold concentration of selected minerals and a low zeta potential crystal generator for treating the aqueous source liquid to produce treated liquid having an enhanced concentration of low zeta potential crystals.

Claims (13)

1. A method for reducing the growth of bacteria and reversing the growth of biofilm in a water system, comprising:

passing source water through a low zeta potential crystal generator and changing the crystalline structure of minerals in the source water to produce treated water having an enhanced concentration of low zeta potential crystal;

passing the treated water through at least one filtration system capable of substantially removing bacteria, viruses, and cysts from the treated water wherein the at least one filtration system is selected from the group consisting of: reverse osmosis filters, microfiltration membrane filters, cellulose nitrate membrane filters and combinations thereof; and

reducing the microbial growth and inhibiting biofilm growth in the water system without the addition of additives by distributing the treated water, filtered source water to the water system.

2. The method of claim 1 , wherein the zeta potential of mineral crystals in the treated water after passage through the low zeta potential crystal generator is at least 25% less than the zeta potential of mineral particles in the source water.

3. The method of claim 1 , wherein the zeta potential of mineral crystals in the treated water after passage through the low zeta potential crystal generator is at least 50% less than the zeta potential of mineral particles in the source water.

4. The method of claim 1 , wherein the zeta potential of mineral crystals in the treated water after passage through the low zeta potential crystal generator is between about ˜5 mV and ˜9 mV.

5. The method of claim 1 , further comprising passing the treated water through a high zeta potential crystal generator prior to passing the treated water through the at least one filtration system.

6. The method of claim 1 , further comprising passing the treated source water through a second low zeta potential crystal generator after the filtration step.

7. The method of claim 1 , further comprising passing the treated water through a pre-filtration system for substantially removing at least one mineral from the treated water prior to treatment in the filtration device.

8. The method of claim 7 , wherein the mineral is selected from the group consisting of: iron; sulfur; manganese; and combinations thereof.

9. The method of claim 1 , further comprising passing the source water through a pre-treatment system for substantially removing at least one contaminant from the source water prior to treatment in the low zeta potential crystal generator.

10. The method of claim 9 , wherein the at least one contaminant is selected from the group consisting of: debris, oils and substances that would interfere with crystallization treatment.
