POTABLE WATER

PRE-TREATMENT PROCESS

Something in your water may be  creating taste and odor problems  while elevating THM and HAA  levels.

Take control in your pre- treatment process with  EarthTec®, an innovative low pH algicide and bactericide solution containing 99.99% biologically active cupric ions (Cu++).

Unlike other copper sulfate products on the market today, the active ingredient in EarthTec® (Cu++) is fully dissolved and stays soluble in water. This means dosage rates are dependent on biological demand rather than water conditions. These characteristics allow you to control TOCs without overtreatment resulting in less copper being added to the environment.

The low pH of EarthTec® aids in assimilability of organic matter to bacteria. The low acidity also decreases solubility of organic matter allowing humic substances to precipitate out.

Controlling natural organic matter (NOMs) with EarthTec® yields many benefits:

• Reduces TOCs, both particulate and dissolved
• Removes taste and odor from the water
• Lowers THM and HAA levels
• Reduces need for other chemicals
• Creates no known carcinogenic disinfection by-products (DBPs)

EarthTec® is a liquid copper water treatment product registered with the US EPA as an algicide and bactericide and Certified to NSF/ANSI Standard 60 as a drinking water additive.

EarthTec® Dosage Rates for Pre-Treatment Process

Dosage rates for the Pre-Treatment Process start at 1 gallon of EarthTec® per 1,000,000 gallons of raw water. This rate is equivalent to .06 ppm of copper. Higher dosage rates may be necessary with high levels of organic load in the source water.

EarthTec® should be injected into the raw water pipe as close to the source as possible. Use a properly sized chemical metering pump with a corp stop and solution tube. Solution tube should be inserted between one-third and one-half way into the pipe.

To insure enough EarthTec® has been added to meet organic demand, take a water sample at the influent of the plant and make sure there is a free copper residual (Cu++).

Note: When initially feeding EarthTec® into an intake line, any bio-film buildup in the line will flake off. This can cause an increase in suspended solids in the settling basins or clarifiers for a few days.

RESERVOIRS

EarthTec® is registered as an algicide and bactericide with the US EPA and Certified to NSF/ANSI Standard 60 as a drinking water additive. This environmentally responsible product is non-toxic to humans and fish when used as directed.

Less Algae
EarthTec® is an innovative low pH algicide and bactericide containing a very high concentration of biologically active cupric ions (Cu++). Conventional methods involve treating for algae after a bloom occurs, resulting in the need for high treatment levels and damage to non-target species. EarthTec® allows long term control and will prevent blooms from reoccurring without buildup of copper on the bottom.

Control of algae and reduction of bacteria yield several benefits:

• Elimination of taste and odor in drinking water due to algae blooms

• Reduction in THM and HAA precursors

• Creates no disinfection-by-products

• Reduces or eliminates need for other water treatment chemicals

Less Work
The dark blue liquid solution of EarthTec® self-disperses, allowing even distribution without spraying or mixing.  Labor costs are greatly reduced.

Less Copper
The active ingredient in EarthTec® is a biologically active cupric ion (Cu++), which is the only form of copper that is useful in controlling algae and bacteria. EarthTec® contains a unique hydrotrope which allows a greater concentration under varying water conditions. The high content of biologically active copper in EarthTec® results in less total copper being added to the environment. The release of copper in EarthTec® is controlled by biological demand (such as an algae bloom) instead of by water conditions. This allows you to treat prior to an algae bloom. The copper will not precipitate out of solution, but will remain fully dissolved indefinitely, thereby insuring long-term algae control without overtreatment.
