냉각수관리포인트 : 1) 공급수질관리. 2) 냉각탑관리 전기전도도상시점검하고용존이온농도관리위해배수제어를한다. 3) 살균, 부식방지제와같은약품을적절히투입한다. Note: 물리적처리방법으로약품을대체하는기술도많이발전되어 Non- Chemical Solution 으로환경오염이없는방법으로선호되고있다. 여과장치 (Filtration) 는 ; 매일시스템내로유입되는현탁물질 (suspended solids) 과미세오염물질 (airborne contaminants) 을적절히관리하기위한장치. 여과장치의투자대비회수산출은 ; 설비의수명연장. ( 즉- 펌프씰, 밸브 Seat, 열교환기튜브등의마모를줄여 ) 냉각탑수조의퇴적물쌓임을방지. 열교환효율을개선하여년간 10% 정도의에너지절감효과. 수처리약품의효과를높이고약품투입량을줄여년간투입되는약품비의 15% ~ 20% 를절감. 청소, 세관비용절감 ( 수조, Sump, 열교환기 ). 수질개선으로레지오넬라균의서식여건을차단시킴. 8

Side-Stream Filtration 휠터용량선정방법 - Side Stream Filtration - (1) 순환유량의 5% ~ 10% 기준, or 냉각용량기준 - 3 GPM/Ton: 예 : 800 Ton x 3 GPM/Ton = 2400 GPM 5% to 10% x 2400 GPM = 120 GPM(27 m3 /h) ~ 240 GPM(54 m3 /h) side stream flow rate OR (2) 시스템내총보유수량을매시간처리할수있는용량으로 (1 Turn per Hr Rule); 예 : 총보유수량 = 12000 gallons( 45 m3 ) = 12000 gallons/60 min. = 200 GPM(45 m3 /h) side stream flow rate OR (3) 수조규격을기준하여 (1 GPM/Sq.Ft. Rule) Based on Sump Dimensions for Sweeping: 예 : 수조규격 - 12 W x 24 L W x L = Filter Flow Rate needed to Sweep Sump 12 x 24 = 288 GPM side stream flow rate 11
