PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS
OTHER SET-UPS - OPERATION UNDER UNUSUAL CONDITIONS
INITIAL SETUP:
Materials/Parts:
Teflon tape
Personnel Required
Three Operator/Crew
Equipment Condition
TWPS skid removed from transport vehicle and set on level ground.
Loose items unpacked (off-loaded) from the TWPS skid and placed in their general operational position.
GENERAL:
This work package contains the procedures to set up the TWPS for initial operation if the TWPS is
deployed on a mission with any of the following unusual conditions:
- Chlorinated raw water source
- NBC decontamination mission
- Existing temperatures are above 90 degrees F or expected to go above 90 degrees F within the
next 24 hours
- Sandy or dusty environment
Refer to WP 0009, Cold Weather Set-Up, if the existing outdoor temperature is below 32 degrees F or
expected to be below 32 degrees F within the next 24 hours.
The procedures covered in this work package include:
Sodium Bisulfite System Deployment
Contamination Avoidance Cover (CAC) Deployment
NBC System Deployment
Hot Weather Condition Set-Up
Sandy / Dusty Condition Set-Up
SODIUM BISULFITE SYSTEM DEPLOYMENT
CAUTION
Chlorinated water will rapidly destroy the fibers in the micro-filter elements and
damage the membranes in the RO elements.
If the raw water source is chlorinated, the water must be treated to neutralize the chlorine before the raw
water is discharged into the MF feed tank. The sodium bisulfite chemical injection system is used to inject
sodium bisulfite in the raw water just before the raw water discharges into the MF feed tank. The sodium
bisulfite neutralizes the chlorine in the raw water.
The sodium bisulfite system includes dry sodium bisulfite chemical packages, a five-gallon bucket in
which the sodium bisulfite is mixed with water, a chemical pump with a suction tube, strainer, and ceramic
weight, 3/8-in. tubing, and Adaptor A-11. Adaptor A-11 contains Chemical Injection Check Valve V-613
and a static mixer.
