DESCRIPTION AND THEORY OF OPERATION
EQUIPMENT DESCRIPTION AND DATA
Micro-Filtration System
The micro-filtration system filters the raw water to remove suspended solids and micro-organisms. At
regular intervals the filter portion of the micro-filtration system is automatically backwashed to remove the
solids and micro-organisms from the filter and discharge it through a waste out hose back to the raw
water source. The micro-filtration system includes the following major components (listed in the general
flow sequence through the system):
MF System: MF Feed Tank to TWPS Skid (see Figure 8)
MF Feed Tank T-1. A 1000-gallon collapsible tank to hold a sufficient reserve of raw water to
support regular, automatic filter backwash operations.
MF Feed Tank Bag Filter S-1. A cloth mesh filter bag that fits inside the MF feed tank and
prevents seaweed, algae and other larger material from being drawn out of the tank with the raw
water. Two spare filters are provided in the BII. Water drawn from the MF feed tank is referred to
as "MF feed water".
Tripod Assembly. Supports the 2x10 hose that delivers water to the MF feed tank so that the
hose does not push down on and collapse the tank.
MF Feed Pump P-3. An electric motor-driven pump that is used to draw water from the MF feed
tank and deliver it to the TWPS skid. The pump is deployed off of the TWPS skid near the MF
feed tank.
One 3-in., 3-ft. long suction hose. Connects the MF feed tank to the MF Feed Pump P-3.
Two 3-in., 10-ft. long discharge hose. Connect the MF Feed Pump P-3 discharge to the TWPS
skid connection at Basket Strainer S-2 (see Figure 9 for Basket Strainer S-2).
