    Abstract: Methods of operating candle filter systems for removing solids from MEG recovered from drilling fluids include passing an MEG rich stream to a candle filter system comprising a plurality of candle filter units in parallel, determining a concentration of TDS in the MEG rich stream, determining whether to operate the candle filter system in a low TDS mode or a high TDS mode based on the concentration of TDS the MEG rich stream, filtering the MEG rich stream in the plurality of candle filter units to produce a filtrate and a filter cake, determining to conduct a cleaning cycle of the candle filter units based on a pressure differential, and conducting a cleaning cycle to remove the filter cake from the outer surfaces of the filter candles. The cleaning cycle is modified to improve removal of solids from the filter candles of the candle filter units.

    Abstract: A method for recycling and filtering rolling oil implemented for a rolling mill M requiring a rolling oil nominal flow rate comprised between 4000 l/min and 30000 l/min in an oil recycling and filtering plant having a circuit including, successively, according to the flow direction of the oil: a dirty oil tank, collecting the rolling oils coming from the rolling mill, a filtering system including several oil filtering devices configured to perform an oil filtering in parallel, a clean oil tank from which the rolling mill is fed with rolling oil at the nominal flow rate. The unclogged muds undergo a secondary treatment by continuous and turbulence-free decantation, thanks to a feed-in of the decanter with mud regulated by a pump.

    Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid. Additional aspects include exchangeable filter cartridges or filter elements in single and multi-round configurations, embodiments with aspiration tubes and dip tubes and still others with hydrophilic/hydrophobic recovery filters that function as filters and as valves for the recovery port.

    Abstract: An oil separator is provided and includes an exterior shell defining a first interior and first and second openings fluidly communicative with the first interior, a distributor and first and second filter media cartridges. The distributor is integrated within the exterior shell to define a second interior within the first interior, has a length, which is slightly less than that of the exterior shell, being disposed to define opposite spaces between opposites ends thereof and opposite ends of the exterior shell and is sealed to the exterior shell along the length to form first and second passageways from the first opening to the opposite spaces. The first and second filter media cartridges are disposed within the first interior between the opposite spaces and the second opening.

    Abstract: A filter assembly including a filter housing having a longitudinal axis, the filter housing divided into a first filter chamber and a second filter chamber. The filter assembly further includes a first filter element and a second filter element. The first filter element includes a first element top endplate, a first element bottom endplate, and a first filter media positioned between the first element top endplate and the first element bottom endplate. The second filter element includes a second element top endplate, a second element bottom endplate, and a second filter media positioned between the second element top endplate and the second element bottom endplate. The filter assembly further includes a solid tube positioned between the first element top endplate and the second element bottom endplate.
