Benefits of technology

[0016]In a water treatment system in accordance with the invention a small amount of dry chemical is used to generate a concentrated liquid solution in an enclosed environment, thereby greatly reducing environmental risk. Further, the invention minimizes chemical usage and greatly reduces trihalomethane formation during well rehabilitation.
[0059]Direct or indirect slime formation is a property of many types of nuisance bacteria found in well water systems. Once a film is formed, growths and absorption of suspended and colloidal materials increases the rate of accumulation.

Problems solved by technology

Typical wellfields, whether involving single or multiple wells, are highly susceptible to bacterial invasion during use.
Bacteria causes biofouling of the well screen and / or the well formation, decreasing well efficiencies and creating treatment problems for the water obtained.
Also, high bacteria levels in groundwater and raw water pipelines create problems with the more advanced treatment methods.
Conventional means of groundwater bacteria control using gross quantities of chlorine and acid based chemicals may be damaging to the wells in the long-term.
Further, conventional means may also jeopardize advanced treatment methods, for example methods utilizing membranes.
Such liquid state chemicals pose an increased the risk to the environment.
In many areas chlorine combined with naturally occurring organics in the groundwater create carcinogenic by-products such as trihalomethanes, which poses a human health risk.
The use of calcium hypochlorite alone may cause plugging of the well.

Embodiment Construction

[0069]The water treatment system may be a stationary unit (FIG. 1) mounted at the wellhead (FIGS. 3 and 4) or mobilized to the site as a portable unit (FIG. 2). The water used to prepare the treatment solution may be obtained from any water source. Usually it is most convenient to use water directly from the well to be treated.

[0070]Referring to FIG. 1, a stationary unit 101 is shown. The stationary unit is approximately 24″×24″×15″ in size and can be easily mounted in the area of the wellhead.

[0071]Water flows through the input line 113 to the sediment primary filter 102 to remove debris. The water then flows through the surface tension control 103 which directs polarities of water molecules in one direction in order to soften the water. The water then flows through the fluid control panel 104, the batch totalizer 105, the temperature gauge 106 and the pH adjuster 107. The water then flows into the calcium hypochlorite (lime ion) canister 108 where a calcium hypochlorite solution i...

Abstract

A water treatment system for producing a sodium hypochlorite solution to control bacteria levels in well water containing: a pH adjuster; a container containing solid calcium hypochlorite for producing a calcium hypochlorite solution; and a container containing solid sodium carbonate for producing the sodium hypochlorite solution and a method of controlling bacteria levels in well water by using intermittent injections of a sodium hypochlorite solution with alternating pH values.

Description

PRIORITY CLAIM[0001]This application claims priority to U.S. Provisional Application No. 61 / 154,840, filed Feb. 24, 2009, the contents of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]This invention relates to a system and method for the treatment of water systems. The invention more particularly relates to the control of subsurface bacteria associated with groundwater wells.BACKGROUND OF THE INVENTION[0003]The environmentally safe and economical production of clean drinking water continues to be a source of concern throughout the world. Typically, where the primary source of drinking water lies just under the ground surface, wells are used to obtain the water. Typical wellfields, whether involving single or multiple wells, are highly susceptible to bacterial invasion during use. Bacteria causes biofouling of the well screen and / or the well formation, decreasing well efficiencies and creating treatment problems for the water obtained. There...
