Menu 7/8: Start time T1/T2
(Starting time point T1 and T2 for filtration cycle)
Note for selection of start times:
The pump starting times are primarily set according to the times of incoming greywater being
processed in the bioreactor with MBR filtration. It is recommended to have two - three hours for
biological treatment before starting with the filtration process.
Example:
If showers are taken mostly in the morning between 07:00-08:00, then the previous filtration
cycle is recommended to be finished before 07:00. T1 or T2 set to 10:00.
It is important that the filtration cycles, A1/A2, running time (T1 or T2) does not overlap with
next start time (T2 or T1). If this is the case, then the second time start will not occur as
required. (Example: With T1/T2 12 hours apart we recommend an A1/A2 of 43/43)
Menu 9: not activated
Menu 10: Number of pump cycles A1/A2
The intervals A1 and A2 determine how many pump cycles, A (incl. 15 min filtration time/15 sec
backwash/17 sec break), will occur after start times T1 and T2.
The number of pump cycles is adjustable from A=0 to A= 60.
The pump cycles start when the starting time point T1 or T2 is reached.
Fig.: Example illustration of start times and pump cycles
The pump cycle can be interrupted by the float switch "BRmin –" (when the water level for the
membrane falls below the minimum allowed level) and "CLmax +" (when the treated water tank
is full).
Note/Example:
A2 = 0, no filtration cycle when T2 is reached
From our example above, T1 starting at 10:00 and T2 starting at 20:00 (after evening water
usage between 17:00-18:00), we have 7 hours available for pump cycles (10:00-17:00).
It is easiest to convert to seconds, 1 hr = 3600 sec, so 7 hours is 25200 sec.
A single pump cycle is 932 sec. long (incl. 15 min run time/15 sec backwash/17 sec break).
Ncycles = 25200 sec/932 sec = ca. 27 for A1
For the evening treatment, we have available 11 hours (20:00-07:00) or 39600 sec.
Ncycles = 39600 sec/932 sec = ca. 43 for A2
