International Classification:

B01D 35/14

US Classification:

210110, 210117, 210136, 2101952, 2102572

Abstract:

A home RO filtration system includes a membrane module having an inlet connected to a feed line, the membrane module also having a concentrate outlet coupled to a concentrate line, and a permeate outlet coupled to a permeate line. The permeate line communicates with a faucet. The system includes a flush reservoir communicatively coupled between the permeate line and the feed line. The system is configured such that after the faucet is turned off, a portion of permeate is delivered to the reservoir and then delivered to the inlet of the module to flush the module.

Abstract:

A reverse osmosis system that includes a housing which receives feed water and a membrane element within the housing to filter the feed water. The membrane element includes a permeate outlet and a concentrate outlet. The reverse osmosis system further includes a sensor that monitors the condition of the water that exits from the membrane element. The reverse osmosis system further includes a first set of indicators that are located remotely from the housing. The first set of indicators showing a condition of the system based on data obtained from the sensor. The reverse osmosis system further includes a second set of indicators that are located near the housing to show a condition of the system based on data obtained from the sensor.

Abstract:

A reverse osmosis system that includes a housing having an inlet port, a permeate port and a concentrate port. A membrane element is within the housing. The reverse osmosis system further includes (i) a first connector that is connected to the inlet port; (ii) a second connector that is connected to the permeate port; and (iii) a third connector that is connected to the concentrate port. A key is inserted between each of the first, second and third connectors. The key is configured such that the key cannot be inserted between the first, second and third connectors unless each of the first, second and third connectors is properly connected to the respective inlet, permeate and concentrate ports. In some embodiments, the key is configured such that the key cannot be removed from between each of the first, second and third connectors when there is pressure at the inlet port.

Abstract:

Some embodiments of the present invention relate to a reverse osmosis (RO) system that includes a housing and a pre-filter within the housing such that feed water flows into the housing and enters the pre-filter. The reverse osmosis (RO) system further includes a membrane element within the housing such that the pre-filtered water flows from the pre-filter and enters the membrane element and permeate exits the membrane element through the housing. In some embodiments, the housing includes a first end cap at one end and a second end cap at an opposing end such that feed water flows through the first end cap into the pre-filter and pre-filtered water flows from the pre-filter into the first end cap. In addition, the pre-filtered water may flow from the first end cap to the membrane element such that permeate exits the membrane element through the first end cap in order exit the housing.
