Causes of Scale Fouling:

Even in hard water areas, pipes will not scale unless the saturation index of the water is exceeded. If the water is under-saturated or at equilibrium saturation, there will be no scale. Conversely, "soft water" can scale if it becomes over saturated. The saturation index of water is controlled by it's acidity (or alkalinity which is the reverse) which we establish by pH measurement. The lower the pH, the more acid the water and the more it can hold in solution. The higher the pH, the less acid the water, the lower the saturation index, and the less the water can hold dissolved minerals. We raise the pH by heating the water, causing pressure drops (eg taps) and adding chemicals. By raising the pH, we are reducing the ability of the water to hold minerals in solution and these minerals are forced to precipitate and cause scale fouling. Recirculating systems (eg cooling towers, steam generators, water recovery systems) operate at cycles of concentration with pressure drops and temperature variances causing both supersaturation and pH increases simultaneously. In addition, Industry, for process reasons, will add lime or an alkali to their liquors which i) raise the pH and/or ii) oversaturate the liquor. All these are called "Scaling Events"

Mechanism:

The AquaVantage Sender/Control Unit sends an electronic "message" to a double coil assembly wrapped about the exterior of the pipe. The "message" is within a broad band of discreet frequencies covering over 20kHz and powered many times a second. The current through the coils is alternating, thus we have an oscillating magnetic field. The result is Induced Digitally Pulsed Transverse Electromagnetic Frequency Fields from low frequencies and extending through to Ultrasonic frequencies which are constantly varying in strength, intensity, frequency, and indeed, ultra-sonic power. The AquaVantage field is quite unique and not duplicated by any other product or system. The Induced Transverse Electromagnetic Multi-Frequency Field uniquely created by the AquaVantage System strips the scaling minerals ions off the water molecules, creates sites of nucleation and forces the oppositely charged ions to combine. The result is inert and non-scaling crystals of Calcium Carbonate which simply wash through to waste or settle out in time vessels such as clarifiers. We call this mechanism "Crystallization Dynamics and Induced Fields" or CDIF for short.

After treatment, the water molecules and specifically the H2 component will seek to react with and pick up ions from existing fouling. This increased solubility + flow will erode the existing scale. The Ultrasonic frequencies, unique to AquaVantage Systems, also act, and are crucial, to clean the pipes and keep them clean. The Ultrasonics have proven successful especially on the most demanding applications.



Types of Scale Fouling Prevented:

We will normally refer to Limescale or Calcium Carbonate fouling but this mechanism remains effective for other mineral scales as will such as Sulphates and other less well known types of fouling.

The results by my final year students in their reports are indicative of the performance of the AquaVantage System. The system can prevent build-up of scale and also reduce existing scale in flow through hot water systems. The unit does not soften water, it prevents scale formation and reduces already existing scale.

The Faces of Softener Bans

Dealers tell how profits can be threatened and frustions mount due to water softener and discharge bans.
by Tricia E. Cupp

In recent years, water treatment dealers nationwide have inevitably heard the news no POU/POE dealers ever hopes to hear -- regulators have passed a softner discharge ban in their community or a community they service.

So far, the softener and discharge bans have taken on a wide range of appearances nationwide. From Texas, where a 2001 statewide regulation bannes discharge of softener waste into septic systems, to the Midwest where some Michigan communities have banned brine discharge into the municipal sewage system, and California, where just last month the city of Fillmore became the second California city to prohibit any new water softener installations -- period.

The following pages detail the measures the POU/POE industry is taking to overcome these bans and offer a small sampling of the hardships endured by the many water treatment dealser affected throughout the country.

Water softener ban shackes up Souther Cal

On June 11, the water treatment industry turened its attention to the West Coast when Fillmore, CA became the second Southern California city in three months to declare a ban on all new automatic water softener installations.

At issue is brine discharge from softeners into the Santa Clara River, which covers a 100-mile watershed. The federal goverment deemed part of the river "chloride-impaired" and the city was forced to lower the chloride level in the water, targeting softeners.

As a provider of water treatment products and services, the ban has impacted the way GoWater, Inc. (Kinetico), Santa Barbara, CA, does business.

However, as a water treatment professional and a member of the Fillmore City Council, Ken Smedly, GoWater's vice president, was able to plan for potential problems early on.

Changing Gears

According to a city-wide survey, about 80 percent of residents did not know about the ban before it went into effect.

"As a licensed dealer, we try to educate customers about the ban," he said.

GoWater started alerting customers prior to the ban that it was coming, and that it impacted only installations. The dealership also began pushing rentals instead of sales, to prevent future complications with customers.

"People wanted to act right away to get theit systems installed before the ban," said Smedley.

Water softeners for residential and commercial use that were in existence prior to the ban are not affected -- at least , not yet.

Dealers, however, fear the city's next step may be to ban existing softeners. The city has discussed a disincentive for people to not use softener and has talked about imposing a significant penalty on residential wastewater bill, according to Smedly.

July 2004



Controversial California Water Softening Bill Signed Into Law

SACRAMENTO, CA - Assembly Bill 334, which could affect restrictions on residential water softening and has been the subject of much controversy in California during the last several months, has been signed into law by Gov. Gray Davis (D-CA).

The governor's office did not publicize the signing to a great extent - rather, it released a few short sentences to the public:

"AB 334 by Assemblymember Jackie Goldberg (D-Los Angeles) authorizes a local agency to regulate the use and availability of self-regenerative water softening appliances that discharge to the community sewer system," the news release said.

The bill had been sitting idle since its July 21 certification following approval by the California Senate on July 17 by a 22 to 13 vote.

AB 334 will now become law effective Jan. 1 2004.

As previously reported, it lays a foundation for California communities to ban or restrict water softeners because of salinity issues. The provisions of AB 334 which affect the previous industry effort, SB 1006, will be the law of the land in California starting next year.

Water Softener Ban Mulled

TUSTIN, CA - The city of Fillmore is one step closer to enacting a ban on new automatic softeners, the Pacific Water Quality Association reported.

The city engineer presented a revised chlorine study report to the city council May 4. Based on the report's recommendations, the city has drafted a ban on new installation of automatic water softeners within city limits.

The ordinance will be law if no successful challenge can be mounted, the PWQA said.

The next step is a "second reading" of the ordinance tomorrow, May 11. Industry representatives will be present at the meeting to express their concerns over the proposed ordinance, the PWQA reported.

Fillmore is also poised to place a ballot measure aimed at forcing local residents to remove their existing automatic units, according to the PWQA.



AUSTRALIA: Salinity an issue `bigger than terror'

DEGRADED water would become a bigger global problem than terrorism, Governor-General Michael Jeffery has said.

In a presentation of the National Salinity Prize to Engineers Australia yesterday Major-General Jeffery said water problems such as salinity would have a serious impact on the world.

"Water, in my view, will be the next great global problem," he said. "Terrorism will be with us for 30 or 40 years I guess, but water is the really big one."

Many countries were suffering from poor quality water resources, and some supplies were barely drinkable, he said, adding the problem of salinity was "arguably at its worst in Western Australia, South Australia and the Murray-Darling Basin".

"In South Australia, at least 20 per cent of surface-water resources are above desirable salinity limits for human consumption," he said.

This water warning follows that of Adelaide Thinker in Residence Professor Peter Cullen, who has told Adelaide to stop being complacent.

"The ways we think about and use our water resources are the key to the future of our country and to the state of South Australia," he said.

As part of his 10-point action plan for South Australia, Prof Cullen urged the state to take better care of its catchments and lead the way in water management.

"There is economic, social and environmental success for communities that can show the way in the 21st Century," he said.

Conservation Council of South Australia chief executive officer Simon Divecha said "the problem is going to be made worse by climate change".

For example, CSIRO modelling predicted less rain and higher evaporation in the River Murray, which would affect all of South Australia.

"It's really what we have got to start planning for so we are thinking of the future for the next generation," he said.

At yesterday's event, Major General Jeffery said Engineers Australia, together with the Murray-Darling Basin Commission and the National Action Plan for Salinity and Water Quality, had shown great initiative and foresight.

The salinity prize encouraged people to share ideas and practical solutions - even if they did not have a formal engineering background.

"My hope is that many of the ideas arising from the National Salinity Prize will, indeed, become more than just ideas," he said. A $30,000 prize for innovation in dealing with salinity was jointly won by SunSalt, who used inland salt to produce a number of products, and the Australian National Committee on Irrigation and Drainage, for their channel seepage and control project.
