  • Page 6: Receiving

    RECEIVING The System is shipped with all major components in place. Each unit is inspected, tested and calibrated at EcoWater CHC before being shipped. CAUTION Upon arrival, inspect the unit for damage. If damage is evident, notify the freight company immediately and file a damage report.

  • Page 7: Warnings And Precautions

    MSDS sheets for each chemical. Shutting Down the CHC System Skids upon an EMERGENCY. 1. Turn the power disconnect OFF on the CHC’s Motor Controller. Verify the pump has stopped operation (look for motor rotation, and listen for the discontinuation of the standard CHC operational sound and loss of filtration pressures).

  • Page 8: Service Requirements

    CAUTION The use of the CHC Treatment system is in no way intended, to replace or diminish your required service as specified by the manufacturer of your tower or heat exchanger. Please refer to the appropriate manuals and continue the required maintenance as specified therein.

  • Page 9: Installation

    EcoWater CHC recommends the use of Schedule 80 PVC or metal, and does not recommend the use of Schedule 40 PVC. If the customer has specified the use of piping other than Schedule 80 PVC, this will be noted in the installation drawings.

  • Page 10: Initial Start-Up

    Turn ON the system again, and verify and adjust any required flows or pressures. a. The CHC pressure should indicate 84 PSI-100PSI. b. Close down the CHC discharge so that 3-5 psi back pressure is found on the discharge gauge.
  • Page 11 All data should be entered into Ulysses at this point and call made to EcoWater CHC engineering to notify them of the Start Up CSR being created for their approval and processing.
  • Page 12 Complete the Installation Certificate and have it signed by the customer. Conduct all required training sessions for the local EcoWater CHC representative as well as any service personnel specified by the customer. (Pass out and discuss Operation Manual, Instruct Personnel on Service Requirements, Instruct Personnel on required troubleshooting as shown in manual.

    The basket strainer is designed to remove any large particles from the water before it enters the CHC pump. Isolation valves are located at both the inlet and outlet of the basket strainer and are used to isolate the basket strainer from the water flow during servicing.
  • Page 14 Discharge Assembly Toroidal Conductivity- EcoWater has chosen to utilize a Toroidal Conductivity Sensor. Conductivity is a measurement of the dissolved solids within water. This sensor is utilized to help control the overall maximum conductivity of the system water. The advantage of this technology is measurement without any electrical contact between the electrode and the process fluid.
  • Page 15 The probe produces a small voltage (about 0.06 volt per pH unit) that is measured and displayed as pH units by the CHC Control Station (CHCCS). The pH probe is a combination electrode, which combines both the glass and reference electrodes into one body.

    2. Verify that the CHC Chamber and Filtration Discharge Valves (at Skid and Tower) are open. 3. Turn ON the power of the CHC unit, by rotating the pump switch(s) into the “Auto or ON” position. As the controller is activated, the corresponding pump should start.
  • Page 17 5. Verify that the float will move from one extreme of the flowmeter to the other, this step verifies that the float and rod have been relocated correctly. 6. If the Flowmeter does not have a cover to prevent Algae growth, order a cover from CHC. (PN # 100000020) Installing the Corrosion Coupons (Optional) Most systems includes the provision for conducting Corrosion Coupon Testing.
  • Page 18 10. Open the isolation valves and make sure no leaks are present. 11. Adjust the flow meter until the five to eight GPM flow rate is achieved. 12. Return the coupons to EcoWater CHC for examination and analysis. 13. A report will be generated and returned to you with the results.

    CHC Control Station Theory of Operation The Control Station has been designed to monitor and control the CHC treatment system. Its screen layout has been designed to minimize the need for customer interaction as well as minimize confusion in screen function and layout. There are User Screens as well as Set Up screens. The Set Up screens will be configured at the installation and do not require configuration by the user, for this reason, the Set Up screens are Password protected.

  • Page 25 This keeps the harder layered scale from forming. It is normal to see a cotton like build up on the fill of a tower when treated by the CHC system, however, it is formed in a manner that allows it to be easily removed with a light touch. Normal cleaning of the CHC treated towers is still required as specified by your tower manufacturer.

  • Page 29: Cycles Of Concentration

    TDS, such as water from the Pacific North West, the contribution could be noticeable. When water is treated by CHC, reactions in the CHC chamber will force some dissolved Calcium and bicarbonate to form CaCO colloids.
  • Page 30 So everything is increased 3 times, including TDS: TDS = 267 ppm. However, when one uses CHC treatment, some Calcium and bicarbonate are converted to CaCO colloids, so at a cycles of 3, the water chemistry will be the same except Calcium will be ~ 150 ppm as...
  • Page 31 Basic Water Chemistry and Understanding the Water Analysis Results The water analysis provided by EcoWater can be difficult to understand. However, by understanding the terms shown in that analysis, you can make sense of your water analysis. Example of Water Analysis provided by EcoWater A standard water analysis includes pH, alkalinity, total hardness, calcium hardness, magnesium hardness, chloride, TDS, conductivity, cycles of concentration and bacteria population.
  • Page 32 Terminology pH: The pH is a measure of acidity or alkalinity of water. pH < 7 is acidic, pH > 7 is alkaline and pH of 7 is neutral. As pH increases, water becomes less corrosive but the scaling tendency of some insoluble salts, such as calcium carbonate and calcium phosphate, increases.
  • Page 33 Magnesium hardness (Mg): Mg, like Ca, is leached from the soil by rainwater. It contributes to the total hardness but is generally present at much lower levels than Ca. Magnesium hardness is a calculated number based on measured total hardness and calcium hardness: Magnesium hardness = Total hardness - Calcium hardness Total hardness: This is the sum of Ca and Mg hardness.
  • Page 34 Waters are commonly classified in terms of the degree of hardness. There are different standards, as listed in the following Table: Table: Water hardness Classification Developed by Water Quality Association Term ppm as CaCO Soft < 17.1 Slightly hard 17.1 – 60 Moderately hard 60 –...
  • Page 35 Chloride (Cl ): Like Sodium (Na), most chloride salts are very soluble in water. They can cause corrosion at high levels. Chloride is used to calculated cycles of concentration because it is stable in cooling water systems. Total Dissolved Solid (TDS): TDS is the total concentration of dissolved components, such as salts and sugar.
  • Page 36 If cycles are too low, there will be too much blow down, thus reduced water saving. Also, cooling water may not get enough CHC treatment at low cycles. Examples of causes for changes in cycles of concentration: a). Conductivity meter is out of calibration and not working properly.
