It removes the scale which is fixed to the equipment of the cooling
water system by using the principle of electrolytic method.
(Removes solid scales by using " Electrolytic Technology")
This is Cooling Water Cleaning System which prevents scales from
being generated at Cooling tower filter, circulation piping, Evacon
tube, etc, (Prevents re-gaining Scales on Pipes, Filter, Tubes
etc)
It removes the scale which is fixed in cooling towers and heat
exchangers while preserving water quality and atmosphere. (Saving
and improving the quality of water while it removes scale)
It kills bacteria and microorganisms such as legionella and
salmonella in cooling water, and removes green algea. (Reduces
Bacteria and microorganisms (i.e as legionella and salmonel)
and removes green algae)
Using environmentally friendly products (DaJaBaRa), which has
caused water pollution and environmental pollution by using
existing high-risk chemicals. It excelled in environmental
protection and energy saving after installation. (Eco-Friendly by
reduces using chemicals)
B. Installation Location
CW Supply piping between cooling tower and heat exchanger
C. Processing Capacity (RT : Ton of Refrigeration)
The processing capacity per unit of cooling water cleaning system
should be greater than the replenishing volume of the cooling
tower.
In the case of 500RT, the circulation volume of the cooling
water is 390ton/hr, so 390ton/hr x 0.012=4.68ton/hr (replenishment
amount of the cooling tower).
The standard processing capacity per unit of 500RT is 5.0ton/hr and
this is greater than 4.68ton/hr which is the replenishment amount
of the cooling tower and so, install 1 unit of 500RT.
D. DaJaBaRa Installation Effect 1.
Arresting Ca²+ (calcium ion), Mg²+(magnesium ion), such as scale
generating ions dissolved in water onto
cathode surface -
Maintaining the concentration to below the
solubility -
Preventing scale generation 2.
Inhibits generation of microorganisms productioin by radical
bydroxyl and chlorine -
Inhibiting Slime -
Inhibiting green algae ※
Radical hydroxyl group : Strong chemicals for oxidizing with
non-toxic character froim the known
substances (fluorine, ozone, chlorine) 3.
Anti-Corrosion -
Prevents corrosion by changing cooling water into alkaescent
water

Electrolysis Chemical
Process
-Water flows between the anode (+) and the
cathode (-) through the electrolytic water
bath.
In this process, basic Ph is
formed on the cathode surface and acidic Ph is formed on the anode
surface.
- Separation and removal of precipitates such
as CaCo2, MgCO3 through chemical reaction on the cathode
surface.
•Ca(HCO₃)₂+20Hˉ→CaCO₃ ↓ + 2H₂O +
CO₂ˉ²
•Mg(HCO₃)₂→MgCo₃ ↓ + 2H₂O +
CO₂¯²
-Trough the chemical reaction of the surface of
the anode, it changes the part of the chloride into a small amount
active
chlorine and acts as a
sterilizer. •HOˉ- e OH°(Radical ), CIˉ→ CI°(Radical
