The systems and methods herein are directed a wastewater management system which can be used on a housing unit. The wastewater management system includes a septic tank, pump tank, pressure tank, and pods residing within a drainfield.

A method and apparatus for extracting botanical oil from botanical mass includes milling the biomass and chilling the milled biomass. The biomass is then exposed to a chilled ethanol solvent. Water is added and the solution introduced into a first centrifuge. The clean ethanol slurry is then introduced into an evaporator leaving a two-phase mixture which is introduced into a second centrifuge which separates the water from the pure botanical oil.

A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The outer wall has a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, and the lower collar comprises at least one lock notch spaced around an exterior surface thereof. The lid assembly is configured to couple to the lower collar of the outer wall. The lid assembly has an upper collar configured to threadedly mate with the lower collar. The upper collar has at least one housing that projects from the upper collar, the housing having an interior surface, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch. A pair of pipeline filter assemblies, wherein at least one connection plate is used.

A fuel filter for an internal combustion engine may include a filter housing, a filter housing cover detachably connected to the filter housing, a filter space delimited by the filter housing cover and the filter housing, and a ring filter element arranged in the filter space. The filter housing cover may include a head portion and a foot portion. The filter housing cover may have at least one foot inner diameter and at least one head inner diameter that extend transversely to an axial direction. The ring filter element may have at least one outer diameter that corresponds to the at least one foot inner diameter. The at least one head inner diameter may be smaller than the at least one foot inner diameter. The ring filter element may form a venting device, which may form at least one venting channel that leads into the head portion.

A filter assembly comprises a filter housing defining an internal volume having an inner cross-section defining an inner cross-sectional distance, the filter housing having a base and a sidewall. A filter element is disposed within the internal volume. The filter element comprises a filter media pack at least a portion of which has an outer cross-section defining an outer cross-sectional distance that is substantially equal to the inner cross-sectional distance of the internal volume of the filter housing. A support structure is coupled to at least one longitudinal end of the filter media pack.

A method of filtering a large volume of a medium using a pre-sterilizable, at least partially automated single-use filtration device which includes an unfiltrate inlet, a filtrate outlet, a main line running between the unfiltrate inlet and the filtrate outlet, filter elements arranged in the main line, a venting line and sensors for detecting specific process parameters and regulating means for adjusting specific process parameters, wherein the sensors and regulating means are connected to an external monitoring and control system which is adapted for evaluating and processing sensor data and for piloting the regulating means based on one or more control algorithms, comprises the following process steps: a) filling the single-use filtration device with medium with low flow; b) venting the single-use filtration device through the venting line; c) closing the venting line; d) rinsing the single-use filtration device, in particular the filter elements; e) filtering the medium by means of the filter elements; f) re-rinsing with high flow; and g) closing the main line; wherein the process steps f) and g) are optional.

A filter element for liquid filtration has a hollow-cylindrical filter medium body and an end disk covering an end face of the filter medium body. A central cutout axially penetrates the end disk. An outflow channel for liquid to be filtered or filtered liquid is arranged at the end disk and connects to a liquid collecting space. The outflow channel extends from a radially outward wall surface of the filter medium body to the central cutout of the end disk. The outflow channel is controlled by a drainage device. A filter device with a filter housing provided with such a filter element has a drainage device that controls the outflow channel. A filter device with a drainage device having a first drainage position for draining only water and a second drainage position draining water from a water collecting space and liquid from a liquid collecting space is provided.

An oil filtration unit having an inlet adapted to receive contaminated oil from the surroundings and to release the contaminated oil to an inner opening of the unit, and an outlet adapted to release filtered oil to the surroundings. The inner opening has therein an oil filter for filtering the contaminated oil. The oil filter has a filter inlet defined by an outer surface of the oil filter, an inner filter volume adapted to receive filtered oil, and a filter that provides fluid/liquid communication between the inner filter volume and the outlet of the unit in order to release filtered oil from the inner filter volume. The oil filter has a top and a bottom end surface, where the top end surface of the oil filter has an aperture for providing fluid/liquid communication between the inner opening of the unit and the inner filter volume.

A filter element includes a first end cap, a second end cap, and an intermediate end cap disposed between the first end cap and the second end cap. A ring of first filter media circumscribing a first central cavity is disposed between the first end cap and the intermediate end cap. A ring of second filter media is disposed between the intermediate end cap and the second end cap. The filter element also includes an air-bleed conduit axially extending through the first central cavity and comprising a first portion integrally formed with the first end cap and a second portion integrally formed with the intermediate end cap and configured to connect to the first portion thereby forming a conduit for transmitting fluid.

Removing sediment from storage tanks without physically entering the tanks. More specifically, embodiments are directed towards inserting fluid into the storage tank via a liquid return line and injecting air into the storage tank via an air injection line to suspend sediment, draining and filtering the sediment, and returning the filtered fluid back into the tank via the liquid return line.
