Abstract: An inlet filter includes a cap and a body that are securely connectable to one another. Once connected, these elements form the structural backbone of the filter. Disposed between the cap and body is a transparent cover that allows one to view a filtering screen located within.

The biofiltering system comprises a bed of peat overlying the effluent absorption area, the peat defining a biofiltering medium having a predetermined biofiltering capacity, and a fluid flow regulator for allowing to the wastewater effluent to be treated to flow at a flow rate greater than the biofiltering capacity of the peat, while not exceeding a predetermined threshold value.

Abstract: Liquid components are separated from a liquid using separation devices, such as filters and membranes, in which capillary forces, which retain the liquid component to be separated in the separation device, are effective. If the amount of liquid is very small, it can be very difficult to remove the liquid component to be separated in the separation device in a free and unchanged form. This process step is simplified or facilitated by a wedge-shaped cut-out at an exit end of the capillary or in a columnar body which is in contact with an exit end of the capillary. A radius of curvature of a wedge edge is smaller than a radius of the capillary. A base side of the wedge-shaped cut-out is adjacent to a collecting chamber in which the separated-off liquid component is collected, and in which the capillary forces are smaller than interfering forces in the capillary itself.
