Dear Kattrina

There are a few questions clarifications required 

1) Source of wastewater and incoming pollution load and flow rate

2) Process scheme or process flow chart

3) is it a new phenomena occurring now or since the beginning of your wastewater treatment plant? If this is a new phenomena then you need to look into what cha fed in the factory processing has been done causing the wastewater characteristic changes. Either to eliminate that change or review the scheme...

4) we could then realise the main reasons for excess foaming matter once we know the answers above.
