The Hydrokon system controls scaling by changing scale forming ions to neutral molecules with our positively charged electrode and ground.  These stable molecules stay in suspension rather than attaching to wetted surfaces as scale.  This is done on a continual basis during the normal recirculation of water past our electrodes.  Removing the ions from the water also allows the water to dissolve existing deposits.  The continual recirculation of the water also controls biological growth by raising the pH of the water and by the flow of water through our electrical fields. 

An electrostatic water treatment unit for use in any water circulating system where SCALE is a phenomena is now available from Baron Technologies, Hyderabad, Telangana, India.

Water when subjected to electrostatic field changes the characteristics if scale forming compounds and throws off their equilibrium. This change in water scale forming compounds incapacitates them from causing or forming scale. The compounds are converted to colloidal forms which are kept in suspension. These colloidal do not even adhere to metal surfaces.

These colloids or the accumulation of TDS gets out of the heat exchangers during blow down. In circulating systems, they tend to settle down at very low pressure zone in the tanks which need to be flushed out whenever the conductivity limit exceeds 2500. This occurs once in a month or it depends on the raw water condition.

The most important feature involved is producing the required electrostatic  charge. Experiments have been done with magnets, combination of metals and electricity. Only use of electricity in creating the electrostatic field has proved to be successful. This technology is proved to be the most powerful energy of the three. The power required is synchronized from the power pack to the electrode which is housed inside the water treatment chamber. The power is synchronized with the capacity, water conditions, water flow rate and pipe dimension

 

HOW ELECTROSTATIC HYDROKON WORKS

Electrostatic water treatment involves the passing of system water through an imposed d.c. or static electric field. Electrostatic water treatment has been proposed to operate as a dispersant to foulants, particularly calcium carbonate particles. It has been theorized that the electric field passing through the water will in effect induce a like surface charge on foulants and calcium carbonate particles. The similar charge on particles will prevent agglomeration and as a result deposition will be decreased. It has also been theorized that electrostatic water treatment can inhibit the growth of bacteria.

 

Typical Connection Fittings.

Typically, electrostatic water treatment devices are installed in cooling water systems either in a pipe bend configuration or a side stream configuration. An electrostatic water treatment device consists of a voltage supply, an electrostatic rod and a reaction chamber. The insulated electrode rod is placed inside of the reaction chamber and water is allowed to flow in the reaction chamber and around the electrode. The voltage supply delivers a DC voltage at a specified level and current limit to the electrode. Water Systems typical voltage and maximum current levels are 12,000 V and 0.02 - 0.45 mA.

Using ELECTROSTATIC HYDROKON no other water treatment equipment only of particles scale bleeding in cooling towers sump.

 

1. Due to the unique ELECTROSTATIC HYDROKON properties, there are not requirements for other forms of water treatment

2. Do not apply phosphate or any other anti-scalant either before or after ELECTROSTATIC HYDROKON.

 An important note about iron, manganese and copper in the water supply.

Iron and Manganese

Just as with conventional water softening media, HYDROKON needs to be protected from excess levels of certain metals that can easily coat the active surface, reducing its effectiveness over time. Public water supplies rarely, if ever, present a problem, but if the water supply is from a private well confirm that the levels of iron (Fe) and manganese (Mn) are less than 0.3 mg/L and 0.05 mg/L respectively. Copper should be less than 1.3 mg/L.

Copper

Copper usually originates from new copper plumbing upstream of the HYDROKON system. If this condition exists, we recommend waiting 3-4 weeks before placing the system in operation. This will allow the copper surfaces to be fully flushed and develop a natural protective surface. To further minimize any problem with excess copper the plumbers should be advised to avoid applying excess flux on the inner surfaces of the pipe and to use a low-corrosivity water soluble flux.

  

1. ELECTROSTATIC Hydrokon should be located in the position selected and agreed with our Technical Representative-AFTER THE PUMP AND BEFORE THE HEAT EXCHANGER, CHILING PLANTS and CONDENSER PLANTS.
2. ELECTROSTATIC Hydrokon must be installed by using pipe unions or flanges.
3. The flow rate required for ELECTROSTATIC Hydrokon of stated diameter are minimum flow rates to ensure proper functioning consistent with minimum head losses. It is essential that this flow rate or greater be maintained. It is advisable to check the flow after installation to ensure that:

(a) Sufficient water is being passed to fulfill process conditions.

(b) Flow requirement to enable ELECTROSTATIC Hydrokon to function efficiently are being achieved.

4. System which is already heavily scaled and on which ELECTROSTATIC Hydrokon descaling is taking place, should have all filters or areas of low flow checked to avoid the possibility of blockage with pieces of scale or sludge.
5. All chemical treatment must be discontinued, except the use of chlorine or chlorine dioxide as sterilent or for the prevention of algal growth. It is advisable, to flush the system with fresh water before installing the ELECTROSTATIC Hydrokon, in case if chemicals were being used.
6. On recirculating systems such as cooling towers, evaporative condenser or air conditioning plants, the level of concentration must not exceed 3000 ppm CaCo3.To maintain this level the amount of makeup water and bleed must be adjusted accordingly.
7. It essential that all queries should be cleared directly with the COMPANY’S TECHNICALREPRESENTATIVE BEFORE INSTALLATION. Problems arising after installation should be discussed with the Technical Representative before any remedial action is taken.

  

THE ELECTROSTATIC HYDROKON SYSTEM WILL WORK EFFICIENTLY WITH CORRECT WATER FLOW RATE & BLEED

FLOW RATE

A minimum flow rate is the most critical condition for effective operation.

The minimum flow rate required is 7 ft. per second over the system itself. The selection chart is shows the size of unit required to treat a particular flow rate.

In order to achieve a satisfactory flow rate it may be necessary to install a unit of as given in the selection chart and that of the circuit pipe. If the flow rate is too low, the Electrostatic Hydrokon systems will itself scale up, thus insulating it and rendering it ineffective.

DISSOLVED SOLIDS

For scaling to be prevented, the concentration of dissolved scaling salts must still be kept under control. In general a maximum TDS level of 3000 PPM is recommended, although higher levels may be found to be satisfactory in certain circumstances. A good bleed on the system is, therefore, essential to counteract the concentration of cooling towers base tank is also recommended particularly in the per/week of operation

MAINTENANCE

The ELECTROSTATIC HYDROKON SYSTEM is maintenance free, provided that it has been correctly installed and the simple operating instruction is followed. It may occasionally require cleaning of cooling towers base tank, but check the after water test report with computer simulation report doing so.

While it is possible to operate cooling towers at higher levels of conductivity, continued bleed of the system is necessary to keep concentrations of particulate matter at appropriate levels. Water use and discharge fees will be reduced as a result of operating at higher conductivity levels. Except in special conditions the normal and proper operation of a tower will involve bleeding or blow down to maintain the water conductivity at between 3200 and 3800 mS/cm of conductivity.

Bleed off in cooling tower bottom: A bleed is set for following months:

1. March- April -           1% of water flow rate twice in a week.
2. May – June -           2% of water flow rate twice in a week.
3. July – August-Sept. - 5% of water flow rate twice in a week.
4. Oct – Nov – Dec -           5% of water flow rate twice in a week.

 

Things to watch for: During the first 30-90 days:

• Drains may unplug occasionally from the cooling tower(s) as old scale is removed from your air-conditioning re circulating system
• You may also see milky water while the de-scaling is taking place. This is simply an increase

in the calcium in the water because HYDROKON is removing old scale deposits from  pipes & condensers.

 

Good practices:

The Electrostatic Hydrokon system before installation, we recommend that you clean by HCL Acid of  HEAT EXCHANGER / CONDENSER tube ,Cooling Towers etc.

We also recommend that you drain your water Cooling Towers sump. This should be done7 to 15 days after Electrostatic Hydrokon is installed, and again in one year. This is a good practice that can dramatically increase the life of your water cooled appliance.
