CHAPTER 1 INTRODUCTION
Section I. General information
1-1 Purpose. This Technical Manual (TM) describes the operation and maintenance of the water purification system
Installed onboard Water Purification Barges Information on other systems and equipment Installed onboard is in TM 55-
1930-209-14 & P-1 and P-2, and P-4 thru P-17 TM 55-1930-209-14 & P-1 8 contains appendices common to all TM's.
Location of major barge components is shown in Figure NO TAG.

Scope. The Reverse Osmosis Water Purification Unit (ROWPU) system processes seawater or brackish water
into drinking water Normally, this system processes seawater supplied by the seawater system (TM 55-1930-209-14 & P-
2), and creates product water Chlorine Is then added to this product water by the chlorination system (TM 55-1930-209-
14 & P-4) The resultant drinking water is discharged into four storage tanks that are part of the drinking water system (TM
55-1930-209-14 & P-5)

Warranties and guarantees The ROWPU system is government furnished equipment. This TM, therefore,
contains no applicable warranty/guarantee Information

System description. The ROWPU system has two identical units, ROWPU 1 and ROWPU 2, that process
feedwater (seawater or brackish water from a river or lake) provided by the seawater system (TM 55-1930-209-1 4&P-2).
This ROWPU system produces two products through reverse osmosis (RO). brine water or dirty water that Is dumped
overboard and highly filtered non-saltwater called product water. The product water, with the addition of chlorine from the
chlorination system (TM 55-1930-209-14 & P-4), becomes drinking water. Drinking water is pumped into the drinking
water system's four drinking water storage tanks or directly overboard (TM 55-1930-209-14 & P-5)
Components of the ROWPU system are listed in Table 1-1. Location of ROWPU 1 components is shown in Figure
NOTAG and ROWPU 2 components In Figure NOTAG A block diagram of the ROWPU system is shown In Figure NO
TAG ROWPU system installation Is shown on drawings referenced In Appendix A
