High throughput nut shell filters for purification of oily process water and industrial wastewater.
Operating Principle
In oil fields, Petreco Hydromation Nut Shell Filters are used to removed suspended solids and insoluble hydrocarbons from produced water, surface water, sea water, river, lake, and well water. In metalworking, power generation, municipal, chemical, and petrochemical applications they treat and remove suspended solids, oilu residues, ash, and metallic hydroxides from industrial liquids.
Hydromation nut shell filtration systems five you double the throughput efficiency of conventional deep bed sand or graded mixed-media filters to filter our suspended solids and hydrocarbons. Under normal operating conditions, they remove 95-99% of suspended solids, and 90-99% of insoluble hydrocarbons, without use of chemicals.
The media scrubbing cycle prevents filter bed fouling. Unique Hydromation nut shell filters is a patented media scrubbing cycle that fully reconditions the filter media during each backwash cycle. This scrubbing cycle is initiated automatically, whenever the filter bed becomes dirt-laden. A change in pressure differential across the filter bed, or an automatic preset time signal, activates backwashing.
The current design incorporates the high intensity of a mixer to vigorously agitate the media bed during the scrubbing cycle. The mixer is combined with the separating efficiency of a rotating backwash scrubber screen to produce the optimum separation of the scrubbed media from the concentrated backwash fluids.
Key Features
Oil Bath Filters
Original air filters were a paper thing that allowed air to pass while trapping dirt particles of a certain size. If you looked inside an old tractor's air filter case it appears that they were filled with the scrap metal swept from around a machine shop metal lathe. You also have a cup with oil in it (this is a pretty ingenious method of cleaning the air in the tractor's intake tract).
Ultrafit Cartridges
You can now have OEM performance without the high cost of filter housing retrofit.
The Story of Hydraulic Fluids
The original hydraulic fluid, dating back to the time of ancient Egypt, was water. In today's applications synthetic hydraulic fluid has been specifically designed to help improve the energy efficiency of the machinery in which it is used. Its primary function is to convey power. Hydraulic systems will work most efficiently if the hydraulic fluid used has low compressibility. Other important functions of hydraulic fluid include protection of the hydraulic machine components.
