thread164-41936: PAC slurry pumping
Hi I need some basic design information on PAC slurry dosing systems, capable of achieving 30-50mg/l for pesticide removal as part of a drinking water treatment process stream.
What does the system comprise of - ie bulk PAC storage tank, day tank, pumps?
How is PAC to be dosed - eg concentrations in the day tank, carrier water requirements, wetting and mixing of PAC etc
kind regards

RE: PAC Slurry Dosing Suytems
On smaller systems, feed control is achieved by regulating the flow of dry carbon through a dry feeder equipped with a slurry pot.
Carbon slurry piping systems are designed to provide approximately 1 gal/lb of carbon. Velocities 3.5 to 5 ft/sec are best.

Talk to your metering pump supplier but they usually have stainless steel bodies.
Dust can be an issue when you are batching up the slurry.
I assume you have done the labwork on the pesticide removal because some pesticides like atrazine are not removed very effectively with PAC.
