Activated alumina process is one of the most prevalently used adsorption methods for the defluoridation of drinking water.
Activated alumina was used of 3/8 inch (9.5 mm) diameter.
The removal efficiency with
activated alumina was found to be maximum up-to 98 percent and it required low operator skills.
Defluoridation of water with a
activated alumina: batch operations.
* Using
activated alumina technology, both community and domestic defluoridation can be carried out.
However, they are not cheap: Countertop water distillers go for $200 and up, and an
activated alumina defluoridation filter--most come in cartridge form and can be placed in-line under counters--are costly, too, and need to be changed out frequently.
If you wish to clear up your tap water from fluoride and chlorine, try reverse osmosis, distillation, or
activated alumina filtration system.
Calculation of the Required Rate of Pollutant Removal by Air Cleaner/Filter Compound [C.sub.eriterion], R, [mu]g/h Q, cfm [F.sub.required], Name [mu]g/[m.sup.3] [mu]g/h Formaldehyde 33 (27.0 ppb) 24125.3 62.5 20620.9 Toluene 300 (79.0 ppb) 56413.5 62.5 24555.9 Sorbent media of activated carbon is selected for toluene removal, and
activated alumina with potassium permanganate is selected for formaldehyde removal based on the sorption ability of the media.
Rigid cell filters are available utilizing granular activated carbon or a 50/50 blend of carbon and
activated alumina impregnated with 5% potassium permanganate (Kmn[O.sup.4]).
