Oil filtration and Oil Block filters

Definitions

The term Oil and Grease includes fats, oils, waxes, and other related constituents found in wastewater. Oil and grease are quite similar chemically; they are compound (esters) of alcohol or glycerol (glycerin) with fatty acids. The glycerdes or fatty acids that are liquid at ordinary temperatures are called oils and those that are solids are called grease (or fats).

Oils and fats in wastewater

Fats and oils are contributed in domestic wastewater in butter, lard, margarine, they are commonly found in meats, cereals, seeds, nuts and in certain fruits. Kerosene, lubrificating and roads oils are derived from petroleum and coal tar and contain essentially carbon and hydrogen.
These oils sometimes reach the sewage in considerable volumes.
For the disposal of mineral oil on surface water and sewage systems, most governments have special requirements on the quality of wastewater.

Oil Block filters: 99% removal of free, dispersed and emulsified oils

Filter Oil-Block absorption cartridge are specifically designed and manufactured for high efficiency removal of free, dispersed and emulsified oils from water.

The Oil-Block absorption cartridge is filled with an unique co-polymer. This element absorb the hydrocarbons and actual bonds the oil in a very short time. The water flows radial into the cartridge and the adsorption media instantly encapsulate the oil and solidify.

Capacity

The standard Oil-block cartridges will absorb 2 liters of Oil before the differential pressure of 2.5 Bar is reached. After saturation the filter blocks and can be easily removed. The blockage prevent any bypass of oil.

Applications

Water treatment
Mud pit cleaning
Clean-up of displacement water
Acid flow back
Completition fluids
Pipeline/systems purge/clean-up hydro test discharges
Ballast and bilge water clean-up
Run-off surface water

Benefits

99.9% removal of all oils in one single pass
Cartridge block after saturation, so no pass of hydrocarbons is possible
Removal of all strong emulsified in a single pass
The absorption capacity is more than 2 times its own weight (up 8 times)
No realased adsorbed hydrocarbons
No direct contact with saturated media during handling
High flow rates
Reliable and simple solution
Easy handling and operation
Fit into existing cartridge units
