Tiaano ElSr (Scale Remover - No Chemicals)

About Us

Water evaporation leads constant increasing of salt concentration in the

cooling tower water. Wherever there is a use of cooling water; Scale,

Corrosion, Bio-fouling and Algae are the cause concern for engineers &

management. Together they create major problems including...

• Health hazards,

• Increase in power consumption,

• Increase in water consumption,

• Reduction / poor in cooling efficiency,

• Life expectancy of equipment is less.

• Increasing the manpower dedication.

Conventionally, cooling tower water is treated by the method of addition of chemicals or by water

softening. Both inhibit scale deposition but have number of disadvantages like… water bleeding in

cooling tower, high operating cost, not an environment friendly and corrosive nature.

Tiaano-ElSr, an Electrolytic Scale Remover:

In order to overcome the limitations of conventional cooling water treatment, Tiaano developed a new

concept in this field, removal of scale (both calcium & magnesium carbonate) by electrolytic

operation, by using ‘Tiaano-ElSr’. Tiaano, India an ‘ISO 9000-2008’ and ‘CE mark’ certified

company, incepted on 1992 with well-equipped in-plant facilities and qualified engineers for

designing, manufacturing, testing, supplying & installing the electrochemical water treatment

equipments including Tiaano-ElSr, an electrolytic scale remover.

However, state of art electrolytic scale remover Tiaano-ElSr produces Oxidants in the water. Oxidants

prevents the corrosion, Bio-fouling, Scaling, Micro-organism growth and spread of airborne bacteria.

Tiaano-ElSr consists of reactors. Reactor-SR removes the scale from the raw water and control the

TDS available in the water. Reactor-EC generates Sodium hypochlorite for the removal of airborne

bacteria, bio-fouling and algae.

Tiaano-ElSr is an independent equipment, getting installed separately out of the Heat exchanger’s

cooling water circuit. Water from the cooling tower pond is continuously circulated through the Tiaano-

ElSr via circulation pump

Process of scale removal is getting carried out, when the Tiaano-ElSr is connected to power and

water flow through it. Its construction is purely by using corrosion resistant materials of GRP, UPVC

& Platinum group precious metal oxide coated titanium.

Construction & Operation of Tiaano-ElSr



Electrolytic action in Reactor-SR: DC current passes from the cathode, through the electrolyte

(water) in the reaction tank, to the anodes. Due to the electrolysis process, the floating calcium

molecules are deposited on the cathode and the water is returned to the cooling tower free of calcium.

The chemical reaction on reactor-SR cathode is as follows:

Ca(HCO3)2+2OH CaCO3 + 2H2O + CO3 - 2

Mg(HCO3)2+4OH MgCO3 + 2H2O + CO3 - 2

Mg(HCO3)2+2OH MgCO3 + 2H2O + CO3

Electrochemical reaction produces OH ions, which causes scale to sink to the bottom of the tank, produces

corrosion preventing copper and iron ions and creates an environment that prevents the development of

harmful micro-organisms. Scale that accumulates on the bottom of the reaction tank is extracted by drain

valve.

Reactor-EC increases the pH of the water to 8.2~8.7, and uses the chemical reactions caused by

electrolysis to produce oxidants with powerful bactericide effect, preventing corrosion and eliminating

bacteria. OH+ ions that remain near the anodes cause a decrease of pH levels and produce oxidants

which disinfect the water.

Electrolytic action in Reactor-EC:

Salt available in the pond water is composed of sodium and chloride. When DC is passed through the

reactor to the electrolyte (water), the chlorides will disassociate and form chlorine. The basic process

is as follows:

Electrolysis occur in an undivided cell when a DC current is passed through a saline water solution

(e.g. seawater or brine solution). At the anode; oxidation of chloride ions to produce chlorine (Cl2).

At the cathode; reduction of water to produce sodium hydroxide (NaOH) and hydrogen (H2).

Liberated chlorine reacts with the sodium hydroxide to produce sodium hypochlorite (NaOCl)

instantaneously. The overall reaction, sustained by electrical energy, is as

2NaCl (salt) + H2O (water) ---> NaOCl (hypo) + NaCl (salt) + H2 (hydrogen).

Sodium hypochlorite, NaOCl is the powerful oxidant that is used world-wide for the chlorination

of the water for Anti-fouling (prevent sliming, mussel / barnacle growth etc.); Disinfection (for

drinking water, general anti-bacterial purposes in process water, etc.); Chemical

treatment (bleaching, removal of iron, manganese.

High performance Sand filter:

Dirt, algae and sediment gather in the tower basin / pond together with the remaining mineral from

the evaporated water, and travel through the cooling water circuit creating deposits an even clogging

the spray nozzles. This cause uneven water distribution over the filling, resulting in uneven air flow

and reduced heat transfer area.

Reduction in heat transfer capacity reduces the working efficiency of the towers and the energy

efficiency of the condensing system. To overcome this inefficiency, on completion of electrochemical

reaction (electrolytic / electrolysis) the water is passing through the high performance sand filter to

cleans water and capture solids.

What is TR:

“Tons of Refrigeration”

Tons of TR means:

One Ton (1000 kilo grams) heat recovered by an air conditioning system that would melt

one Ton of ICE in 24 Hours.

How to calculate the capacity of cooling tower:

Flow rate x Density x Specific heat x Temperature difference / 3024

• Cooling tower Water flow rate per hour in M3 : 120 • Density of water : 1000• Specific Heat in KACL/ Kg 0 C : 1• Temperature difference in 0 C : 5 • Ambient WBT - 29 0 C
