Description

PENTAIR OSMOTIC MEMBRANE 100 + FR-FLUSH SET is a practical kit for RO systems, designed for effective water purification in installations such as reverse osmosis, an osmotic filter, or a home reverse osmosis system. The set includes a Pentair 100 GPD osmotic membrane, a properly matched flow restrictor, and FR-FLUSH with a bypass for periodic membrane flushing. The solution supports efficient water treatment, helps maintain the performance of the water filter, and makes regular operation of the entire water filtration system easier.

The membrane retains 96-99% of dissolved organic and inorganic contaminants, heavy metals, and selected bacteria and viruses with a size of no less than 0.001 micron. Thanks to the FR-FLUSH set, sediments can be periodically flushed from the membrane, which supports longer and more stable RO system operation.

Effective water filtration in RO systems

The Pentair 100 GPD membrane has been designed for use in reverse osmosis systems. During the filtration process, it retains 96-99% of dissolved organic and inorganic contaminants in water, heavy metals, and some bacteria and viruses with a size of no less than 0.001 micron.

Contaminants are separated from the water stream and discharged to the drain. The purified water passes through the openings to the central spindle, and then, under pressure, flows out of the membrane.

Key advantages of the set

  • membrane capacity is 100 GPD, i.e. about 380 liters per 24 hours,

  • removal of contaminants from water down to 0.001 micron,

  • retention of some bacteria and viruses as well,

  • fits most RO reverse osmosis systems available on the market, including aquarium systems,

  • the FR-FLUSH set enables periodic membrane flushing,

  • the properly matched flow restrictor is included.

FR-FLUSH – membrane flushing set

FR-FLUSH is a membrane flushing set for reverse osmosis systems. It includes a bypass and is mounted to the flow restrictor.

The solution makes it possible to flush deposits from the RO membrane, which helps extend its service life by even several years. This is especially important where the reverse osmosis filter operates regularly and is exposed to gradual buildup of contaminants on the membrane surface.

Installation method

Installing the FR-FLUSH set is simple, but it requires maintaining the correct direction of water flow.

  1. Disconnect the water supply to the system.

  2. Detach the flow restrictor from the membrane housing.

  3. Cut the red hose from the FR-FLUSH set to the appropriate length.

  4. Install the existing restrictor on the red hose.

When connecting the set, pay attention to the direction of flow. The markings in the form of a small arrow on the ball valve and the arrow on the restrictor help with this.

Operation and periodic membrane flushing

To maintain high membrane efficiency, it is recommended to flush it 1 to 2 times a month during system operation.

Flow direction markings beside the valve and restrictor

During flushing, the bypass valve should be opened so that water can flow freely to the drain. After about 2 minutes, the valve should be closed. This allows the RO membrane to be flushed under high pressure.

The membrane should not be used with microbiologically contaminated water or water of unknown origin.

FAQ

What is this set used for?

The set is designed for use in RO reverse osmosis systems. It combines a Pentair 100 GPD osmotic membrane, a flow restrictor, and FR-FLUSH, a system for periodic membrane flushing.

What contaminants does the membrane remove?

The membrane retains 96-99% of dissolved organic and inorganic contaminants, heavy metals, and some bacteria and viruses with a size of no less than 0.001 micron.

What is the capacity of the Pentair 100 GPD membrane?

The membrane capacity is 100 GPD, which is about 380 liters of water per 24 hours.

Does the set fit most RO systems?

Yes, the membrane fits most RO reverse osmosis systems available on the market, including aquarium applications.

What is FR-FLUSH used for?

FR-FLUSH enables flushing deposits from the RO membrane. Regular flushing helps maintain system efficiency and may extend the membrane's service life by several years.

How often should the membrane be flushed?

It is recommended to flush the membrane 1 to 2 times a month during system operation. The bypass valve should be opened for about 2 minutes so that water can flow freely to the drain, and then the valve should be closed.

What are the required operating conditions of the membrane?

The membrane operates in a temperature range from 2 to 45°C and at a pressure from 2.8 to 6 bar.

Can the membrane be used with any water?

No. The membrane should not be used with microbiologically contaminated water or water of unknown origin.

What is included in the set?

The комплект includes: Pentair 100 osmotic membrane, flow restrictor, FR-FLUSH, securing clips, and instructions.
