Bacterial control is accomplished ^vitll a 10 lain]) ultraviolet (UV) unit (Steri-Tronics International, IModel SWIj 80/120), rated at 997o bacterial removal for 303 to 454 liters/min (80 to 120 gpm) water flows. The UV unit is positioned in the filtered water system just inside the laboratory (Figure 5). A secondary, two-tube UV unit (A(iuafine Corporation, *]\Iodel ]\IP-2—PVC) is connected to a l^i filtered sea-water line and used in forage culture operations where bacterial control is extremely critical. HEATING AND CHILLING SEA-WATER A check valve arrangement allows passage of filtered sea-water, on demand, into the heated sea-water system. This system is comprised of a PYREX brand modular heat exchanger (Model (iOO GNB), a 500,000 BTU freshwater boiler, and a 'rhii plastic lined jnimp (Vanton, Chem-Gard, Model CG-PY200). This pump operates eontinuoiusly to circulate the warmed water and insure uniform temperatures through- out the system. Sea-water temperature is controlled automatically by a pneumatic valve positioned in the freshwater ])ipe, between the boiler and heat exchanger. This pneimiatic valve is connected to, and actuated through a control panel. A temperature sensor, positioned in the heated sea-water pipe, is also connected 1o this panel. The control panel records heated and ambient sea-water temperatures, and contains a salinometer (Beckman Model RA5)..
