Hose Connections During Operation. The operator must perform a number of hose hook-ups during operation of the ROWPU;
an understanding of the flow pattern for each of these hook-ups is essential to the operation of the ROWPU (see Figure 2-1).
Cleaning of filters and RO elements is par of the operation of the ROWPU. The in-operation
cleaning functions are media filter backwash (para. 2-21) and RO element cleaning
(para. 2-25), and changing basket strainer and cartridge filters (para. 2-24). Chemical tank
and system flushing procedures are part of shutdown. Hoses used for cleaning and
flushing are identified and illustrated in their appropriate procedures paragraphs.
