Dear All,
Can anyone help me with a design question. We are looking to pump Storm Water which has large quantities of road grit (varies from sand to granite chips upto 15mm diameter).

Hi All,
Here's one for you UK based wastewater engineers.
Can anyone give me some feedback, good or bad about Hidrostal sludge tank mixers.

We are considering using...
Hi All,
Does anyone have experience of Vaughan Chopper pumps.
How do they cope with rag laden sewage/wastewater ?
How well do they chop solids once wear takes place at the cutters ?
Any feedback on these pumps good or bad would be appreciated.

Dear All,
I had a recent discussion with an end user regarding operating a Rotary Lobe pump at Shut Off Head.
The pump is a 4" model & is pumping 6-9% Primary Sewage Sludge (with the possibility of fine sand entrained that gets through the de-gritting process).
Power at shut off head is...
Dear All,
Can anyone advise me of the pros & cons of using Mechanical (Surface Mounted) Aerators vs Venturi Aerators (powered by a solids handling pump) for Waste Water applications.
My only (limited) experience of aerators has been with Venturi aerators which I believe are...
