environment that does not promote bacterial growth. However, high feed water bacterial counts may
necessitate sanitization.
4.2.3 Required Cleaning and Sanitizing Equipment
The following cleaning equipment and descriptions must be constructed of
materials compatible with the recommended cleaning solutions.
During cleaning, the following equipment is required:
Tank
Connect a 50-gallon (190-liter) or larger tank to IT-DS system. The tank should be large enough to
accommodate solution volumes as shown in this section. The cleaning solution will be prepared in
this tank. It should be possible to completely drain the cleaning tank. Conical-bottom tanks are ideal.
Pump
Install a cleaning pump between the system and the cleaning tank. The pump must provide a
minimum discharge pressure of at least 30 psig (2 bar) at the flow rate given in Table 4-1.
The construction materials of the wetted surfaces in the pump must be compatible with the
cleaning solutions. Plastics generally work well with most cleaning chemicals.
During cleaning or chemical sanitization, adjust flow rates as follows (use the highest flow rate
possible per Table 4-1 below):
Filtration
Particulate filtration is required equipment on the cleaning skid to ensure that any solids or
foulants that are removed from the IT-DS module during cleaning or sanitization are not recycled
back into the feed ports of the IT-DS EDI module. The internal IT-DS cell distribution contains small
channels and can become blocked if particulates are not removed from the cleaning/sanitization fluid.
IONTECH recommends a polypropylene high quality 5 micron nominal (90% efficiency) depth
filter cartridge for the cleaning skid arrangement. Filter materials must be compatible with the
cleaning and sanitization fluids.
