Walnut Shell Filter for Oily Water Treatment

Application of walnut shell filter material in oilfield

Aug 06, 2021 · Walnut shell filter is the key equipment in oilfield water treatment system. Its structure affects the filtration process, filtration effect, evaporation and environmental pollution. The combination with the cleaning tank will also affect the filtration and cleaning effect, which determines the recovery and reuse of filter materials.

Experimental Study on Oil Removal in Nutshell Filters for

water treatment. Nutshell lters composed of black walnut or pecan granular media are an established produced water-treatment technology for tertiary oil removal. Guidelines for the size and operation of nut-shell lters have evolved mainly by trial and error, with limited published operating data. This laboratory-research program tested PETRECO HYDROMATION Nutshell Filter SchlumbergerPETRECO HYDROMATION filters use crushed black walnut shells, known for their strong affinity for oil, as the filter media. The filter bed is cleaned using a unique backwashing mechanism, which can typically use feedwater instead of filtered water. Compared with other technologies, nutshell filters can handle higher inlet solids and oil.
