Sizing & Application

HydroBlend APPLICATION SIZING GUIDELINES

The HydroBlend Water Treatment Systems have a wide range of applications depending on many variables. These include: 1) Water Flow Rate, 2) Water Volume Treated, 3) Water Line Size, & 4) Application.

Although HydroBlend is very forgiving in its applications, correct sizing must occur, otherwise the possibility of over or under-feeding. The most critical factor in correct sizing is flow rate. This will most likely determine the correct unit to place. If the flow rate is too slow for the unit applied, then over-feeding will occur which will call for more frequent cartridge replacements. Too high a flow rate for a unit may restrict the water flow which is not desired.

The best way to determine the flow rate is to take the average water usage for the day and divide it by the hours of operation, and then by 60 minutes. If a monthly water bill is available, take the total water volume and use the following formula to determine the average flow rate:

Ex. 24,000 gallons per month / 20 days of operation = 1,200 gal/day

1,200 gal/day / 8 hours of operation = 150 gal/hour / 60 minutes = 2.5 gpm.

Using either of the 500,000 gallon units would not be a correct application of the product. This would result in high over-feeding. (Refer to the specification sheet for minimum flow rate required) The SC605 would be the correct application in this instance just as long as the peak flow rate did not exceed the 3/4" maximum flow rate (17.5gpm @ 50psi). If it does exceed the maximum flow rate, then the unit should be side streamed parallel to the main line.

Most plumbing designs are over sized to allow for peak flow rates or growth. Just because there is a 1 1/2" line does not mean that the unit has to be the SC1.5. The average flow rate will determine the size of the unit. If the water usage characteristic is on/off-on/off-on/off, then determine what the flow rate is during the time that the water is on to correctly size the unit.

The type of unit applied is determined by the flow rate and not the desired frequency of cartridge changes. Do not apply the 500,000 gallon units solely because they require less frequent cartridge replacements.

Unless the water chemistry is unusual, it should have no effect on the sizing of the unit.

Any low average water flow rate should always use a ScaleStick. This usually applies to flow rates of less than 1 gpm (coffee, espresso, ice machines, steam equipment, etc.).

Some applications are unique and require special consideration. Ensure that all the variables are taken into account when applying units, especially the flow rates.
