ENVirol™ is AFL’s efficient and economical oil removal cartridge range which effectively takes total oils from oilfield-produced and industrial waters.
The range now includes ENVirol™ Original, ENVirol™ Plus and ENVirol™ Block.
The polishing out of trace hydrocarbons from partially processed water prior to discharge has always proved a difficult and costly exercise. Emulsions and the dissolved fraction can now be economically removed using ENVirol™ filter cartridges as a polishing phase after existing oil removal technologies.
The ENVirol™ media is surface-modified substrate composed of selected fibres which are chemically modified to have a high affinity to forming a powerful electro-chemical bond with hydrocarbons.
ENVirol™ has been designed to provide high efficiency and take up of all types of hydrocarbon with exceptional holding capacity.
An instant and irreversible bond is formed with the ENVirol™ media technology as hydrocarbons pass through the filter cartridge.
The ENVirol™ Original cartridge will adsorb up to 300% of its own weight and remove 99% of all oils present in a single pass.
Very high flow rates are achievable with ENVirol™ Original without any increase in pressure or loss of flow rate.
Benefits of ENVirol™ Original
ENVirol™ Plus technology shows a reliable and steady increase in diiferential pressure. Flow rate is reduced as the cartridge reaches saturation, giving a simple and safe signal of the cartridge change-out point.
Benefits of ENVirol™ Plus
In the ENVirol™ Block cartridge polymer media technology instantly forms a barrier when in contact with hydrocarbons. This gives ultimate protection in downstream processes of discharges.
