A one cubic ft GAC filter is 7.5 gallons of GAC. A flow of water through that filter at 2.5 gpm has an EBCT of (7.5/2.5) = 3 minutes. Just make sure you use the same volume units to do the calculation. A GAC filter must have sufficient EBCT to do the job plus enough safety margin to cover variations in the quality of the water being treated.

Most cement plants today use coal as fuel for the pyroprocessing. It takes 200-450 kg of coal to produce 1 tonne of cement; The cement industry is the largest source of PM (particulate matter) emissions, accounting for 40 percent of …
The formation and emission of sulfur xide (SO 3) in coal-fired power plants has received increasing attention due to its adverse effects on the operation of plant and environment.With the wide application of selective catalytic reduction (SCR) systems, the problem caused by SO 3 has become severe, especially when high sulfur coal is …
The characterization and optimization of the performance of three types of bag filters has been performed in a hot gas filtration facility. The tests results show that bag filters are a suitable alternative for industrial applications operating under high temperature and high …
A new technical route is explored to realize the integrated design of dry gas desulfurization and dust collection, combining dry duct injection technology with bag filter technology.
Our bag filters, designed for dust extraction and product recovery, are tailored to any flow rate. Enhanced with electronic controls and versatile design options, we create the ideal filtration solution for your specific needs. Our advanced bag filter technology adeptly prohibits dust emission in multiple industries.
Filtration is a critical element in power generation systems. Whether maintaining the performance of gas-fired turbines or preventing the discharge of fly ash from the chimneys of coal or other sources of solid fuels, proper filtration is key to achieving environmental performance, writes David Appleyard. One characteristic of thermal …
plant or $2 X 106 (1981 dollars) over a 30-yr life. Factors in-fluencing pressure drop include flue gas and fly ash distribu-tion, bag cleaning techniques and frequency, ash composition, bag material, and air-to-cloth ratio. Bag Design and Specifications The most critical element in fabric filter technology is the bag itself.
