Sanitizing Testing Frequency :
Physical / Environmental / Operational : 1. Air Quality (A specific System shall be added According to ANSI/ASHRAE 62.1 for example ) 2. Clarity (The Drains in the lowest points shall be sharply visible) 3. Cyanuric Acid (Shall Not Exceed 100 ppm) 4. Enzymes 5. Oxidation Reduction Potential (ORP) 6. Temperature (Shall Never Exceed 40c) 7. Replacement
Physical / Environmental / Operational : 6. Temperature (Shall Never Exceed 40c)
Physical / Environmental / Operational : 6. Temperature (Shall Never Exceed 40c)
Physical / Environmental / Operational : 6. Temperature (Shall Never Exceed 40c)
Physical / Environmental / Operational : 7. Replacement : Water Replacement shall be done when the TDS of water exceeds 1500 ppm. Water Replacement shall be done as a seasonal regular application. To calculate the Water Replacement Interval (in days): (Rule of thump) WRI (days) = Volume (m3) X 88 No. of Swimmers per day
Pool Water Heating Calculations
Pool Water Heating Calculations : Water Temperature is a very important parameter for bathers comfort. There are Two Major Heating Loss Types in Pools Pool Heat-Up Pool Surface Load vaporization Load
Pool Water Heating Calculations : Pool Heat-Up Load (q1): q1 = [ρ X cp X V X (tf - ti)] / t X 3600 where q1 : pool heat-up rate, (watt) ρ : density of water = 1000 kg / m3 cp : specific heat of water = 4180 J/kg°k V : pool volume ,(m3) tf : desired temperature, (usually 28°C) ti : initial temperature of pool, (10°C) t : pool heat-up time, (Hr) q1 = [1160 X V X (tf-ti)] / t Example : Volume =86m3 , (Tf – Ti) = 18 , time = 12hr Q1 = 1.16 x 86x 18 / 12 = 149.64 KW ~ 150 KW
Pool Water Heating Calculations : Pool Surface Losses Load (q2): q2 = U * A * (tp-ta) where q2 : heat loss from pool surface, (KW) K(U) : surface area transfer coefficient Recommended K= 25 - 60 W/m2.°K in wind speed 5-10Km/Hr A : pool surface area, (m2) tp : pool temperature, (°c) ta : ambient temperature of pool, (°c) A= 12 x 6 = 72 m2 Tp = 29 , Ta = 35 Delta T = 6 Q2 = 60 x 72 x 6 = 25’9820 W = ~26 KW
Pool Water Heating Calculations : Total Load : Q (Total) = Q 1 + Q 2 Q (Total) = 150 kw + 26 kw = 176 kw OR .. We Can Do it in another way !!

Try it ? Assume a swimming pool with : Main pool Surface area : 50 m2 Average height : 1.3m Lower pool area : 12m Lower pool height : 0.5m Jacuzzi volume : 10 m3 Determine : •The filtration rate if you know that the pool is residential . •The head of the pump . Assuming that the Pressure Drop in Piping (6m) and the Filter Pressure drop (10m), the Return inlet Pressure Drop (5m) and the Heat Exchanger Drop (10m) •The boiler capacity of the boiler required to heat the pool and the Jacuzzi .
