Abstract
A water treatment system includes a filter module and a reverse osmosis module secured to the filter module. The filter module contains two filter cartridges. The modular structure of the components enables the filter module to have the two filter cartridges connected as separate pre and post filters or connected in series as a single two-stage filter. Similarly the modularity permits multiple reverse osmosis modules to be connected is a daisy chain manner for increased treatment capacity. A novel bracket structure aligns ports of the filter module with corresponding ports on the reverse osmosis module.
Claims21
A water treatment system comprising:
- a filter module with a first manifold with a first filter cartridge and second filter cartridge mounted thereto, the first manifold includes a filter inlet port and a filter outlet port, the first filter cartridge has a first inlet connected to the filter inlet port and has a first outlet, and the second filter cartridge has a second inlet and a second outlet that is connected to the filter outlet port;
- and
- a first reverse osmosis module secured to the filter module and includes a second manifold with a first RO inlet port, a first RO outlet port and a first drain port, the first RO inlet port being connected to the filter module and receiving water therefrom.
A water treatment system comprising:
- a filter module with a first manifold having an inlet port, an outlet port, and a first filter cartridge containing a filter medium and connected between the inlet port and the outlet port;
- and
- a first reverse osmosis module secured to the filter module and including a second manifold with a first RO inlet port and a RO second inlet port in direct fluid connection, a first RO outlet port and a second RO outlet port in direct fluid connection, and a first drain port and a second drain port in direct fluid connection, the first reverse osmosis module having a first reverse osmosis cartridge attached to the second manifold between the first RO inlet port and the first RO outlet port;
- wherein the outlet port of the filter module is aligned with and fluidly connected to the first RO inlet port of the first reverse osmosis module.
A water treatment system comprising:
- a filter module with including a first manifold having an inlet port, a first intermediate port, a second intermediate port, and an outlet port, the filter module having first filter cartridge fluidly connected between the inlet port and the first intermediate port, and having a second filter cartridge fluidly connected between the second intermediate port and the outlet port;
- and
- a first reverse osmosis module secured to the filter module and including a second manifold with a first RO inlet port and a RO second inlet port in direct fluid connection, a first RO outlet port and a second RO outlet port in direct fluid connection, and a first drain port and a second drain port in direct fluid connection, the first reverse osmosis module having a first reverse osmosis cartridge mounted to the second manifold and fluidly connected between the first RO inlet port and the first RO outlet port;
- wherein the first intermediate port of the filter module is aligned with and fluidly connected to the first RO inlet port of the first reverse osmosis module, and the first RO outlet port of the first reverse osmosis module is aligned with and fluidly connected to the second intermediate port of the filter module.
