• Cartridge Filter Unit

    NOV Water Services offers the BRANDT™ Cartridge Filter Unit, which is used globally for the treatment of completion fluids during wellbore clean-up, gravel pack operations, workovers, water injection operations, and general seawater (brine) filtration.

     

    Description

    The stainless steel filter pods can be fitted with nominal rated or absolute rated pleated cartridge elements or oil absorption filter elements. Each pod holds fifty, 39 in (1000 mm) cartridges. The design of the manifold allows the operator to choose between single, dual parallel or dual series vessel use. The dual series configuration is used with two stage filtration, using coarse filters in the first vessel and fine filters in the second. The Cartridge Filter Unit can be positioned as a polish filter downstream of the diatomaceous earth filter or as a stand-alone filtration unit. This filter unit is particularly effective for filtering seawater and treating produced water during well testing, when fitted with oil absorption filters.
