To select the module that is right for you, start by answering the following basic questions:
1) What is the average flow rate of the influent to the PHX module?_______(GPM)
Maximum flow?______(GPM)
Minimum flow?______(GPM)
2) What is the pH range of the influent to the PHX module? Max.___(pH) Min.___(pH)
3) What is the desired effluent pH range? Max.___(pH) Min.___(pH)
4) What is the desired maximum change in pH? pH =_____

Batch Treatment should be considered if the average flow is
below 5 gpm. If the desired pH change is greater than 7 pH units,
or if the system is to be used for concentrated dumps, a batch system may
be the best choice. Finally, if local regulations require the inherent
safety of a batch system, choose PHX Batch Module or consult our System
Engineers for a custom batch system.

Continuous Flow systems generally require less space for equivalent
flow rates, making them the preferred choice for higher flow conditions.
The PHX Continuous Flow systems handle average flows up to 50 gpm.
Continuous flow systems can require ;less operator attention and are widely
accepted in many pH adjustment applications. However, the influent
pH variability must be considered when sizing a continuous flow system.
Consult our office for design of systems with concentrated dumps.

| Batch Mode Sizing:
To size a batch module, determine the total accumulated daily flow and divide by the number of batch treatments per day. The holding tank should be sized based on the flow rate, treatment time and safety factor. Refer to the performance and specifications table to select your pH Plus model. If your required volume exceeds the capacity of the ph Plus Batch Systems, consider a Continuous Flow module or consult our engineers for a custom batch system.

Continuous Flow Sizing:
To size a continuous flow model, use the graph below. Find the intersection of the maximum flow rate and change in pH units. This point will indicate the correct pH Plus model for your application.  |
