Hydraulic Loading and Effluent Quality
CE Commercial System is designed to treat the commercial wastewater from the kitchen, bathroom,
toilet and laundry and capable of producing Advanced Secondary Quality Effluent as specified below.
The daily design flow rate of CE-4200 is 4,200L/day and CE6000 is 6,000L/day.
o
BOD equal to or less than 10mg/L
o
Suspended Solids equal to or less than 10mg/L
o
Total Nitrogen equal to or less than 20mg/L
o
Total Phosphorus equal to or less than 2mg/L
o
Thermotolerant coliforms less than 10cfu/100ml
Treatment Flow
Peak-cut System
Despite its compact size, CE Commercial System can effectively cope with shock loading. The
system has a buffer capacity of 252L for CE4200 and 301L for CE6000. The water level in the system
varies whether there is any inflow or not.
When the water level exceeds the Low Water Level (LWL), the treated water is pumped out to the
pump chamber through the chlorinator by the effluent airlift pump. If the water level exceeds the High
Water Level (HWL), the treated water overflows through the effluent weir to the pump chamber. When
there is no inflow, it takes 15 - 30 minutes for the water level to drop from HWL to LWL.
