Plant Initial Testing
The newterra MicroClear
and leakage tests in our manufacturing facility prior to shipment; however, fittings could shift
during shipment, so it is our standard practice to perform initial testing on the plant after
installation, including dry and hydraulic tests.
The following subsection is presented for one single process train; if multiple trains are
provided, performing the dry test and hydraulic test for each train is identical.
4.5.1 Dry Test
The following tasks have to be performed before potable water is introduced into the system:
Ensure that all tanks are clean and free of any dirt or debris (this is to prevent obstruction
or damage to the piping, pumps, and membranes).
Ensure that all connections have been provided and joints have been tightened.
Check the placement of the air diffusers in the equalization tank(s) and the aeration tank(s)
if incorrectly positioned, proper adjustment has to be performed.
Ensure that a functional check of the electrical and control system has been performed
(please refer to the newterra Commissioning Checklist presented in Appendix H).
Confirm heater/fan and air conditioner operations
4.5.2 Hydraulic Test
The hydraulic test is performed using potable water to:
Check for and fix any leakage;
Check the setting of level switches/transmitters;
Check the hydraulic flow through the plant;
Check if all the ancillary equipment and controls of the plant function as per design;
Recalibrate instruments (if applicable);
Perform clean water test on membranes.
Perform clean water test on the chemical distribution system.
