HYDRAcap
Module Installation Instructions and Rack Design
This Technical Service Bulletin provides information required to install HYDRAcap
Ultrafiltration modules and to demonstrate a sample support rack assembly.
General Guidelines/Rack Design
HYDRAcap
is a stand-alone module capable of withstanding a pressure of 73 psig (5bar)
at 20°C. The following rules are applicable to its installation:
1. The modules should be installed vertically with the filtrate connection at the top
(see figure 1). Vertical installation is highly recommended. If horizontal orientation
is the only choice, the modules should be placed with the feed and concentrate
ports facing upwards to avoid air entrapment.

2. Feed water should enter the bottom of the module. Under certain conditions such
as high solid loading, it may be necessary to alternate the feed direction from
bottom-to-top to top-to-bottom.
