Did you Select, correct Capacity Air blower for your aeration Tank/Basin ? Any water and wastewater treatment process Air Requirement is inevitable for clear process. many engineer is is still confusing and trouble to choose exact capacity for that application,
for your easy understand we given simple solution with example.
HP of the Blower / Fan = ( CFM X [....]
Why Fine Bubble is better then Coarse Bubble? Generally the volume of air here we are taking about in size of bubble diameter, suppose if bigger say 2 inch roughly , the bubble travel time is quickly reach to the upper surface of the liquid medium from the bottom, which deliver might be Diffusers or Jet aerators.

A Ton of refrigeration (TR), Amount of heat require to melt a ton of Ice over 24 Hr period, that much of energy is called ton of refrigeration
A Refrigeration Ton is approximately equivalent to 12,000 BTU/Hr British thermal unit / Hour
one ton of refrigeration capacity can freeze one short ton of water at 0°C (32°F) in 24 hours. [....]
Lime dosage requirement is most important process in Sedimentation Process, to separate the solids from liquid by gravity. Sedimentation is the basic process, whether water and wastewater treatment,
In water treatment process, first remove Girt / fine fibers in presedimentation basin and follows coagulation–flocculation is most commonly used.
We find adequate /require amount of alkalinity (HCO3) first,which will help to [....]
Normally, the filter backwash water sludge very tough to remove or separate that one, generally in many plants that will have design the back wash water pipe line laid into main effluent collection tank. But this is not a right method.
Instead of that, try this method, though which has bit of cost investment involve, this is only an perfect [....]
