The Problem

  • lDue to evaporation, concentration of salts in the  cooling tower water increases constantly.
  • lThis is the main reason for the deposition and scaling  on cooling tower’s elements and inside the CW pipes.
  • lCooling tower’s scaling causes a diminution of the efficiency of the cooling tower’s efficiency.
  • lCooling tower’s scaling is a natural habitat of  legionella bacteria.

Conventional CW Treatment

lMainly by means of addition of chemicals or by water  softening.

lBoth inhibit scale deposition but have disadvantages:

  • High operating and maintenance costs
  • Large quantities of cooling tower’s water bleeding.
  • Soft water are very corrosive and damage the  cooling tower’s metal parts and CW pipes.
  • Both of them are not environment friendly process.

Our Solution is the Scale Remover

In order to overcome the  disadvantages of  conventional cooling water  treatment we have  developed a totally new  concept in this field., The Scale Remover based on electrolysis process.

The main advantages of our system are:

  • The electrolysis scale remover replaces and eliminates  chemical water treatment.
  • The electrolysis scale remover SR fight bio life and alga by the power of chlorine produced next to its anode.
  • The electrolysis scale remover SR collect all free calcium carbonate and magnesium carbonate from the water and prevents any scale deposits on the cooling tower elements
  • The electrolysis scale remover SR reduces water bleeding and total water consumption to 2/3 of conventional consumption.
  • The electrolysis scale remover SR is controlled by a  microprocessor based PLC and its valves are  electrically activated 
  • The electrolysis scale remover SR is ecologically safe and environmentally friendly.
  • The electrolysis scale remover SR extend the  cooling tower life.
  • Electrolytic chamber made  carbon steel, coated by  backed epoxy.
  • Made of titanium mesh  with MMO coating.
  • Has an operating life of  8-10 years.
  • Made of stainless steel.
  • Does not release iron ions  into the water.
  • Elecrically isolated from  the enclosure

The chemistry of the process

  • By applying electrical power between the anode and the  cathode , a chemical reaction is activated and electrolysis  process takes place. Water from the cooling tower pond is  circulated throght the electrolysis scale remover SR
  • 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 SR cathode is as follow:

                     Ca(HCO3)2+2OH’ >>>>> CaCO3 + 2H2O + CO3¯²  

                     Mg(HCO3)2+2OH’ >>>>> Mg(OH)2 + 2H2O + CO3¯²

  • The electro-chemical process counteracts the cooling tower  water concentration due to evaporation and to intake of dust  and gases from the surrounding air.
  • On the cathode surface a high pH and alkaline environment, is  created . This alkaline environment causes the settling of  hydroxides and minerals of low solubility, enhancing formation  of less soluble carbonate and hydroxides.
  • The anode, made of catalytic metal, frees electrons from its  surface and thus, oxygen and carbon dioxide gas is evolved,  producing disinfecting conditions which act against the growth  of microorganisms.
