The approximate dosages / flow rate for Excelight units, with clear water are:
EL411AK:
11GPM@16mj/cm² 6GPM@30mj/ cm² 4GPM@40mj/ cm²
EL720AK:
15GPM@16mj/cm² 8GPM@30mj/ cm² 6GPM@40mj/ cm²
EL1129AK:
22GPM@16mj/ cm² 12GPM@30mj/ cm² 9GPM@40mj/ cm²
Disinfection chamber hydraulic performance may limit maximum flow rate. Flow
restrictors may be used to limit flow rate through chamber to ensure dosage.
A 16mj/cm²
dose is suitable for reducing non-pathogenic nuisance organisms only.
A 30mj/cm²
Industry Standard Dose - This is the dosage produced by 2.5"
diameter disinfection chambers when designed using the 1966 US Department of
Health UV disinfection Policy Statement.
A 40mj/cm²
dosage is now required in NSF/ANSI Standard 55.
