EST Overview
EST Overview
EST all in one solution
How does it work?
The EST system connects to the cooling tower basin and circulates water therein. A controlled constant DC current is applied to the patented titanium nickel oxide anodes, generating the following efects.
Disinfection
1. An alkaline environment of pH 13 is created next to the reaction tank’s inner walls creating a strong disinfectant. 2. Near the anodes, 3-7% of the naturally present chlorides are converted to free chlorine or hypochlorite (OCl-). The OCl- level is programmable to automatically remain at ~0.1-0.2ppm, providing additional disinfection without the risk of corrosion. 3. Additionally, disinfecting radical oxygen, ozone and hydrogen peroxide are produced near the anode.
Scale removal:
The electrical current causes a dissociation of the salts in the water into ions, precipitating the calcium (and other cations) on the reaction tank wall. The EST is capable of precipitating > 30% calcium from the water before it crystallizes into scale, while the remaining calcium is kept dissolved in the water. The calcium precipitation percentage is programmable, automated and varies from project to project. The EST patented scraper system automatically scrapes and flushes the reaction tank to remove the precipitated scale.
Corrosion control:
The remaining Magnesium ions in the water prevent corrosion along with controlled operation >2 MPY.
1- Green Technology
- No chemical feeds or discharge
- Water can be recycled and reused for irrigation
- No discharge cost
- The drained water is re-usable for irrigation, toilets, street cleaning etc.
3- Longer system lifespan
- Cooling system works better and longer
- Low maintenance and low recurring cost
2- Scale, bacteria and Corrosion Control
- All precipitation of salts occurs in the reaction chamber
- No scale in the system heat exchangers, chillers, filler etc.
- Control over corrosion potential due to low aggression of water
- Bacterial growth control.
4 - Full control and supervision
- Performance is monitored with complete control of all parameters
- Fully automatic -self cleaning
- SCADA optional

Chemical pollution
Chemicals have enabled productivity and quality of life throughout the world and are integral to our everyday life. The current global annual chemical production stands at 2.3 billion tons and is projected to double by 2030, according the UN. Driven by economic development, population dynamics and other global megatrends, the chemicals market across a range of industry sectors is expanding. Though regulations have been implemented, experience teaches us that what we once thought was safe, often turns out to have effects that manifest themselves in the long run.

Fresh Water Scarcity
Fresh water is one of the worlds’ scarcest resources. Only 2.5% of the earth’s water is fresh water, of which 70% is frozen in icecaps. Most of the remaining fresh water is too deep underground to access; leaving only 1% of the earth’s fresh water available for human consumption. It’s estimated that 23% of all fresh water spent is utilized for industry, of which a staggering 70% is spent on utilities.
