With regard to the MBR tank high level, I understand why you stop EQ feed when this occurs. In order to design, we will need to know how much wastewater was fed from the EQ each day. If the EQ feed is off while MBR tank level is high, this is ok as long as we know how long feed is off.
Can we record length of feed-off time each day?
Also, is the feed off time significant? If it is only 10 minutes per day, for example, this is not a concern. If it is an hour or more, we need to know
