Ogo Cartridge Filter 03002734871

Cartridge filtration units generally operate most effectively and economically on applications having contamination levels of less than 100 ppm. For heavier contamination applications, cartridges are normally used as final polishing filters.

Pre RO water
Compressed air
OGO Services can provide any replacement cartridge filters for retrofitting or improvement

In the following the basic systems of cartridge filters are listed
Wound cartridge filters:– Material: natural or synthetic yards, which are wounded around a central tube or former.
– Filtration of: sand, scale, lime, rust, fine particles.
– Applications: drinking water, boilers, washing machines, pre- filtration in water treatment, sea water desalination, process
water, chemical processes…
– Filtration range: 0.5 – 150 micron
– Length: 5-10-20-30-40?
Melt-Blown cartridge filters:
– Material: one-piece cordless construction, consisting of pure polypropylene micro fibers, thermally bonded to prevent any
fiber migration.
– Filtration of: sand, scale, lime, rust, fine particles.
– Applications: Water treatment, pure water pre-filtration, fine chemicals, reverse osmosis, sea water desalination, beverages,
solvents, cosmetics…

Filtration range: 1-75 micron
– Length: 5-10-20-30-40?
Activated carbon cartridge filters:
– Material: Polypropylene fleece and net, or washed polypropylene yarn or polyester felt filtering medium and granular activated carbon
– Removal of: color, smell, taste contamination, pesticides, chlorine, organic substances.
– Applications: Potable water, washing machines, anti-chlorine treatment in alimentary, chemical and pharmaceutical industry, pre-treatment for reverse
osmosis units…
– Filtration range: 1-25 micron
– Length: 10-20-30?
Stainless steel cartridge filters:
– Material: stainless steel filtering net with a polypropylene inner core.
– Filtration of: sand, scales, rust.
– Applications: drinking water, washing machines, boilers, pre-filtration for pumps, irrigation systems, protection of industrial systems…
– Filtration range: 70 micron
– Length: 4-5-7-10-20?
Pleated cartridge filters:
– Material: Pleated polypropylene or stainless steel filtering net with a polypropylene inner core.
– Filtration of: Sand, scales, rust.
– Applications: Drinking water, boilers, washing machines, pre-filtration of water pumps, irrigation systems, protection of industrial installations…
– Filtration range: 50 micron
– Length: 10-20?

Sediment filter
Dirt holding capacity (DHC) of filters
Dirt holding capacity of filters in liquid filtration
Definition of dirt holding capacity: The quantity of contaminant a filter element can trap and hold before the maximum allowable back pressure or delta P level is reached.
Values for filters:Sand filtration: 3 to 6 kg of suspended solids (SS) for m2 of filter surface
Anthracite: 7-10 kg of SS for m3 of filter
Bag filter: 2 kg of SS for size 1 (810 x 430 mm)
Drum filter and Disc filter: 0.8 kg of SS for m2/h
Cartridge filter: 0.45 kg for 10 inch cartridge 100 mm retention rating
0.15 kg for 10 inch cartridge 15 mm retention rating
0.54 kg/m2 for 3M Cartridge
0.48 kg/m2 for string wound cartridge
0.19 kg/m2 for pleated cartridge
The following picture show data for the DHC of fine test dust by different media. The data re shown on semi-log coordinates since the relative DHC of nano alumina medium is so great that the data for meltbrown and membrane media would not be discernable. The data demonstrate that the nano alumina medium is capable of extraordinary capacity for adsorbing particles while achieving high retention efficiency. The filter achieves such performance at a water flux equivalent to or greater than other filter media intended for filtering sub-micron particles.
Particle sizes
Techniques based on the sizes of the particles
There are many techniques developed to separate substances based on the sizes of the particles. Some of these techniques are widely applicable. Some of them are only applicable for a particular size. An incomplete list is shown below for different particle sizes with their applicable technique.
Diameter between 1 µm and 1 mm
~ Drum filter
~ Sand filter
~ cartridge filter
~ Bag filter
Diameter between 100 nm – 1000 nm (0,1 µm – 1,0 µm)
~ Microfiltration
~ Ultra filtration
Diameter between 1 nm – 100 nm
~ Ultra filtration
Diameter smaller than 1 nm ( 0,001 µm)
~ Reverse Osmosis
~ Ion exchange
The choice between different techniques depends on several factors like;
~ The amount of pollution
~ The amount of fluid to be treated
~ The properties of the substance which is to be removed this in order of the damage and the choking of the filter
~ Quality of the filtration
~ Investment
Some of the techniques are only suitable for one time. Other techniques the filter will be cleaned and used again, after a while (this can be several years) the filter eventually should be replaced.
