Ovivo® Media Filtration technology comprises of a pressure vessel, media, distribution and collection headers. Typicall filtration flow is down through the media bed, but Ovivo can offer other configurations, given the applciation. We offer a complete line of robust, industry standard, proven equipment. Multi-media filtration delivers high quality water at higher flowrates,when compared to a traditional sand filter.
  • Typically 98% removal of particles > 2 microns
  • Fully Automatic operation
  • Motion-sensitive on offshore application

Ovivo media systems are ideal for customers looking for fully automatic systems, requiring little operator intervention and maintenance. Characterized by consistent high quality effluent, media filters are capable of handling inlet solids content up 20 - 50 mg/l. Higher loading is capable with increased backwash frequency.

Ovivo media filtration uses a 3 (three) or 4 (four) media layered system depending on the quality requirements for the effluent water. Use of the different grades of filtration media allows for a gradual coarse-to-fine media size and therefore, higher particle capture. An air-scouring device is part of the media cleaning system, which ensures that the media bed is fluidized to the optimum amount, effectively removing all trapped solids.

Process operation consists of down-flow influent across a multilayer media bed. Varying the media layers help contain different sized contaminants, resulting in 98% removal of particles < 2 microns. These filters generally run in parallel with all on-line filters so when contaminants begin to accumulate, individual vessels undergo media cleaning by backwash. This provides uninterrupted flow-through to a system. 

Standard single vessel capacities available range from 5,000 to 53,000 BWPD.

Can multimedia filter remove oil?

Although oil removal is possible, efforts should be taken to remove free oil upstream of the media filter.

What are the different materials of construction available?

Available construction materials are carbon steel, stainless or duplex stainless steels for the vessel. Distribution and collection headers are available in a wide variety of materials including stainless, duplex stainless steel, titanium and others.
