How was KentGoldings sewer force main problem resolved.

I am interested in knowing if Kentgolding's force main/underperforming pump station issue was resolved. I have continued to experience similiar problems at a lower capacity facillity with similar force main characteristics. I found it interesting that kentgoldings facility has a 'bioxide' tank. We have correlated our poor performance directly to the application of this product. Increase dosage, force main appears to gas/air bind within a few days to the point of shutoff. Turn off feed, pump performance returns within several days. Changing existing air/vacuum valves to automatic air release valves brought no benefit (although we now have an excellent understanding of the different ARV types). Similar experiences and findings could be of value as we struggle with this problem.

I have other using bioxide with no issues.

Kentgolding made some interesting comments and there was quire a bit of posts in that forum. However, it was never clear at least to me what was the scope of his system. Seemed that most posters were guessing at solutions based on limited information.

Perhaps you can sketch up your force main/pump system showing velocity, pipe size, eleavations, variable speed pumps, constant speed pumps, etc.

Do you have a solids grinder? Is your application a prison? Prison's are not atypical as far a flow and solids.
