Dear All,

 

I'm looking to find out the capacity or dimensions of side launder of an Induced Gas floatator tank installed in our WTP plant. It is a Veolia supplied Whittier Autoflot model 55. Every model has a standard capacity and the capacity of this model is 364 m3/hr. But in the catalog, I could not find the launder capacity; I'm sure this would be a standard one.

I need this because the level switches are not working and in this case we need to set the pump operation at a fixed interval to empty the oil chamber. For this, I need to know the volume of this chamber to estimate the filling time.

I have the GA drawing but dimensions of this chamber can not be found.

Is there a ratio (of total capacity,i.e. 364 m3/hr) or something or some standard to know this in case we don't have the complete information?

 

Thanks in advance.

 

Regards

Yogesh

Hi Yogesh,

If its not too critical, next time you are at the plant use a tape measure to get some measurements, then do a simple estimate calculation.

You can then check the suitability of the estimate when the settings are programmed or configured and you commission the plant change.

You don't need to make such complicated calculations.

 

Just put two level switches.

The level switch setting should be for the oil density.

When the oil level reaches the high switch, turn on the pump.

When the oil level reaches the low switch, turn off the pump.

You can do this on simple electrical relays.

 

 

If you want more control,

install a radar level sensor at the chamber, tie it back to the PLC.

Then you can input setpoint levels for when to start and stop the pump.
