Abstract
A filtration apparatus for separating filtrate and concentrate from a liquid solution is disclosed. The filtration apparatus contains a housing having a discharge opening therein and being capable of containing a liquid solution to be filtered therein. A filter unit is insertable within the housing such that a first side faces the discharge opening of the housing. The filter unit contains a semipermeable membrane located thereon and capable of separating filtrate and concentrate. At least one inlet is located within the first side so that the semipermeable membrane covers the inlets.
Claims20
A filtration apparatus for separating filtrate and concentrate from a solution comprising;
- a housing having a discharge opening therein and being capable of containing a liquid solution therein;
- a filter unit insertable within the housing having a first side and an opposing second side, wherein the first side of the filter unit faces in the same direction as the discharge opening of the housing, the filter unit comprising,
- a semipermeable membrane located on the first side and capable of separating filtrate and retentate,
- a gap between the filter unit and the housing wall to allow passage of the solution to be filtered,
- at least one filtrate inlet to said discharge opening located on the first side, wherein the semipermeable membrane covers the at least one inlet,
- a filtrate port located on the first side and being in fluid flow relationship with the at least one inlet, wherein the filtrate port is oriented to allow filtrate flowing therethrough to flow into the discharge opening of the housing;
- and
- means for sealing the filter unit to the housing for preventing concentrate within the housing from flowing within the discharge opening.
The apparatus of claim 2 wherein said filter unit comprises a neck protruding from the first side thereof, the neck having the filtrate port therein and being insertable into the discharge opening of the housing.
A filter unit for a filtration apparatus including a housing having a discharge opening therein, the filter unit comprising:
- a first side opposing to a second side, said first side having a semipermeable membrane located thereon capable of separating filtrate and concentrate, wherein said semipermeable membrane and said first side are disposed to face the same direction as the discharge opening;
- a gap between the filter unit and the housing wall, to allow passage of the solution to be filtered,
- at least one filtrate inlet to said discharge opening located on the first side, wherein said semipermeable membrane covers the at least one inlet;
- a filtrate port located on the first side and being in fluid flow relationship with the at least one inlet, wherein the filtrate port is oriented to allow filtrate flowing therethrough to flow into the discharge opening of the filtration apparatus.
