A brief réumé with particular reference to the types of deck level overflow
system most commonly used: the hydraulics differ totally from those for a typical
freeboard type of pool where skimmer weirs are directly connected to the pump
suction point. The surface draw-off offers total pool perimeter overflow
channelling for efficient, uniform surface extraction. A good design extracts 30 to
90 per cent of the total circulation flow capacity of the filtration plant via the
overflow system. |
