Cooling Tower Market Focus
Industry: Cooling Towers - oil refineries, chemical plants, power stations,food processing, building cooling etc.
Application: IVG- CT Treated Water for Cooling CircuitFeature: Lime/Calcium Prevention, Water SavingsBenefits: No Chemicals - Less Wear and Tear - Less Energy – Higher Electrical
Conductivity
Scale Formation
• Due to evaporation of water(impurities left behind)
• Acts as insulation – moredifficult for heat to transfer
• Every 1oF in Refrigerant Condensing Temperature requires compressorto consume 1.5% more energy
• Can lead to System Shut Down
Cooling Tower Water Treatment
Lower Temperature of Water through evaporation
Problem Statement:Water circulating is very corrosive and containsmicro organism and lime.Impurities picked up in cooling tower cause scale andlower thermal efficiency.Impurities also clog piping so that circulating pumpsneed to work harder and consume more power.
Typical Solution:Aggressive chemicals are used to control scaling andcorrosion, producing high amounts of chemicaldischarge.
H2O Vortex Solution:IVG-CT treated water grinds down lime impuritiessignificantly reducing scaling without hazardousdischarge.

Technology Overview
The design enables a consistent and low energy method to achieve physical water treatment(PWT) water treatment in a variety of end use applications.
Pre-former: Inlet of the vortex generator provides smooth outward direction of the flowthrough toroidal motion toward a set of well-defined channels.
Channels: The fluid is directed through a set of channels, each with vortex-forming geometry.Each channel delivers a very high velocity stream of vortex flow tangentially into a vortexchamber.
Vortex chamber: Vortices from the channels form a strong and stable vortex flow
Toroidal Preformer
Channels
Vortex Chamber
High Velocity Streamcausing a strongly reducedpressure along the vortex axiswith a very low central pressure.There is pressure of 5 bar at theperiphery and almost vacuum inthe center, indicating a pressuregradient of at least 6 bar ormore at higher startingpressures.

Micro-bubbles in water are pulled into the low-pressure chamber. Micro-bubblesthat are present migrate towards the center where the lowest pressure is andaccelerated due to the pressure gradient. The bubbles expand and combine in the center in the shape of a string of air
with a very low pressure. The strong hydrodynamic force creates cavitation changing the water balance
and affects the calcium crystals in the water. As bubbles are removed a decrease in viscosity of 5%-17% occurs.
Technology Overview
Heat capacity: + 5% for ice and + 3% for liquid water
Controlled Cavitation: Leads to the formation of lime particles in hard water. The process resultsin low pressure and high temperature micro-zone (solubility of CaCO3 decreases) causing thedissolved calcium and carbonate ions to react and form colloidal calcium carbonate crystals. Thisincreases pH and allows the particles to act as incubation sites for dissolved calcium andcarbonate ions to grow on, in lieu of, metal surfaces.
Fragmentation: Already formed lime particles fragment as they move through the pressuregradients and shear forces.
Precipitation - nuclei formation: Calcium bicarbonate (CaHCO3)2 in the water is forced to precipitate out in the form of
calcite (CaCO3) – primarily aragonite crystals which have minimal scaling properties –does not precipitate on warm surfaces
Such particles act as seeds (crystallization nuclei) for new lime growth. New limeformation will add to the lime particles rather than cause lime-scaling on the equipment.
For IVG-CT
Example based on the Barona Resort Hotel and Casino inCalifornia.
NOTE: Electric and water utilities will pay incentivesfor electric and water savings. Since they pumptheir own water and do not buy it there are noincentives. They still have a 2.5 year simple payback.
With full water and electric incentives the customer payback will be near 2 years.

A TECHNOLOGY ACCORDING TO GOVERNOR BROWN’SEXECUTIVE ORDER B-29-15
In 2015 Watreco together with its partner Cypress, concluded its first USA Water –Energy Nexus Pilot Project in California under the aegis of Southern California Edison(SCE).
SCE, the largest subsidiary of Edison International (NYSE:EIX), is the primaryelectricity supply company for much of Southern California, USA. It provides 14million people with electricity across a service territory of approximately 50,000 squaremiles.
The innovation developed by Watreco AB, Sweden, achieved reduced water and energyusage and lowered chemical usage in the cooling tower tested in accordancewith Governor Brown’s Executive Order B-29-15 to make California more drought-resilient.

Research Study - Cucumbers
A test was carried out in collaboration between the Advanced Horticulture Company (AlHayer, by Al Ain, UAE) and H2O Vortex, Luxemburg. The main objective was to study theeffect of using Vortex system on enhancing the productivity and other crop properties ofcucumbers under the local conditions of the United Arab Emirates.
Research Findings
• Vortex crop showed in general better results than the reference (control) crop withregard to all parameters tested.
• The growth of the Vortex crop was slightly faster than that of the reference crop.• The total yield expressed in kilograms was higher by 6.35 %.• The sub-optimal or reject cucumbers using Vortex system was less by 19.75%.• The shelf life of cucumbers from the Vortex crop was much better than that of the
reference crop when stored at low temperature.• Vortex system has positive effects not only on the plant growth and yield, but also on
product quality and shelf life as well as on product consistency and taste.
Improvement Centre, Netherlandsstudy provided the similar success.

Case Study – Tomato early plant growth
• Pilot study examined whethertreatment with Vortex ProcessTechnology of the irrigation waterused on tomato plants had any affecton plant growth.
• Plant height, stem, width andinternodal length were significantlydifferent in tomato plants grown inVortex-process water comparedwith the untreated control.
• This study focused ONLY on earlyplant growth phase and no otherinfluencing factors were studied.
• In other studies where full cropswere grown, results were similar tothat found in cucumbers.
In 2009/10 the Vortex was used to grow grapes inAudrey Wilkinson Vineyard, Newcastle AUST
Fertlizer and Water useYield
Water quality was improvedproducing grapes for the first time
on clay soil.
Due to the soil’s inability to absorb water, the vines in the test has never previouslyyield grapes. With use of Vortex Treated water – these vines grew plentiful, highquality grapes. Unfortunately the volume was never measured.

In the desert and in space,the vortex is being used tospray water and fertilizer togrow crops known as AeroPonics. Yields are similar tothat of the cucumbers grownusing vortex treated water.
It’s application is being usedas an aerator to treat sludgeand bio-logical waste as wellas aerate and clean ponds,water ways and fish/shrimpfarms.
It’s also cleaning pollutedrivers and treating waste-water.
