An Anglian Water waste water treatment works was suffering from system downtime due to a number of problems. The system originally consisted of a progressive cavity pump and integral macerator. These units were not fit for purpose and frequently caused blockages in the system.
The System
The system itself contains a raw sewage wet well at the inlet with the medium then drawn through the Pipeliner for treatment to 10mm in particle size. The sewage is then pumped out for further treatment using an Energy Maxi diaphragm pump at 1l/s. The medium is pumped into a rotating biological contactor (RBC) to be treated.
The Problem
Rag and debris would often find themselves getting into the wet well at the start of the system which meant it was being drawn through the pumping system and making its way into the RBC. This often led to expensive repairs and downtime of the equipment. Occasionally, the buildup of rag and debris would be so large it would get stuck in the pumping system itself, due to the macerator not being fit for purpose.
The Outcome
With the Haigh Pipeliner successfully protecting the diaphragm pump, and the system as a whole, it means there will be no expensive unplanned maintenance or system downtime that operators and maintenance teams will have to deal with.
