A septic tank filter system includes a tank. The tank includes an inlet and an outlet, wherein the outlet is disposed on the tank below the inlet to enable a flow of wastewater to be gravity fed from the inlet to the outlet. A filter is positioned in the tank. The filter includes a frame. A filter media is disposed on the frame. The filter media is operable to filter the wastewater of waste material as the wastewater passes therethrough. A top opening is disposed on a top portion of the frame. A bottom of the top opening is located above the tank outlet and below the tank inlet. When the filter media is not clogged, a level of the wastewater remains below the top opening. When the filter media is clogged, the level of the wastewater rises until the wastewater flows over the top opening.

The present disclosure provides a substrate processing apparatus capable of stabilizing the particle level when re-supplying a chemical solution. The substrate processing apparatus includes a circulation line connected to a chemical supply unit to circulate a chemical solution, a filter installed in the circulation line to filter particles in the chemical solution, a supply line connected to a first node of the circulation line and configured to supply the chemical solution to the chamber, and a drain line connected, in the circulation line, to a second node located between the filter and the first node, and configured to drain the chemical solution, the apparatus being configured to operate, during a first duration, from when a pump of the chemical supply unit is restarted after the pump had stopped, to drain the chemical solution that passes through the filter.

A filter assembly includes a canister housing closable by a lid and containing a removable and replaceable filter element cartridge. The lid is part of the filter element cartridge and a single unitary component therewith, such that removal of the filter element cartridge also removes the lid, and replacement of the filter element cartridge also replaces the lid.

A stripping-solution machine and working method thereof are provided. The stripping-solution machine includes: a plurality stages of chambers, which are arranged sequentially in order, wherein each stage of the chamber is correspondingly connected to a storage box; at least one filter device, wherein one end of the filter device is disposed to be connected to a storage box corresponding to a current stage chamber by a first pipe, and another end of the filter device is connected to a next stage chamber by a second pipe. Furthermore, a plurality of valve switches are at least disposed on the first pipe or the second pipe.

In one or more embodiments, a liquid filter 100 to filter fuel or lubricant is provided. The liquid filter 100 includes a housing 102 extending along the vertical axis XX′. The housing 102 has a cylindrical shape and includes a top end cap 104 and a bottom end cap 106 provided at both ends. The top end cap 104 and the bottom end cap 106 are integratedly formed in one piece with the housing 102. The top end cap 104 includes an outlet 108 for allowing outflow of filtered liquid from the housing 102. A hand priming pump 110 is functionally attached to the outlet 108 of the top end cap 104 for easing priming. The bottom end cap 106 includes an inlet 112 for allowing inflow of dirty liquid inside the housing 102.
