Hi ,
I am working on a project which has a Twin Lobe GAs Blowers. I've been asked to calculate the discharge temperature at lower flow rate. Vendor has already specified the temperature rise at max flow. I assume the capacity won't remarkably affect the temperature as it's variable speed.
and...
Hi ,
I am working on a waste water treatment project, we have a Grit Chamber at higher level comparing the downstream Grit classifier , the Grit pumps to push the grit from chamber to classifier is located at the bottom of Grit chamber. in our P&ID , there is a barometric loop that raises up...
Hi all,
I am working on a wastewater plant and there are a few mixing pumps e.g. primary sludge tank mixing pump , digested sludge tank mixing pump and Anaerobic digester mixing pumps.
some vendor offered Fixed speed while the preference is VSD.
Can you please let me know for these specific...
Hi everyone,
I have some PC pumps at the sludge lines of a waste water treatment plant, we are preparing data sheets for vendor.
the pumps mainly have VSDs. the material balance table shows a few different flow conditions.
I am mentioning the design data based on the maximum flow. just...
Hi there ,
I have an aeration system that consists of a 6 meter tall aeration tank with approx. 5 m of liquid. The PD blowers are in a nearby building at ground level. The piping goes up and over the wall of the aeration tank to the bottom of the tank where the aeration diffusers are. I am going...
Hi There ;
I have a question about the vacuum relief valve on digester .
from one side any pressure reduction inside the tank increases the possibility of vacuum and the vacuum relief valve prevents it but from the other side the mixture of air with gas inside the digester is explosive .
please...
