F-801 Internal RO System by GE Osmonics

1.9Optional Equipment

GE Osmonics offers a number of optional items to adapt the equipment to meet specific needs. Options are available to improve the quality of the feedwater to the RO. Frequently requested options are briefly described in the following paragraphs. If more information is needed, or if other options are desired, please consult the factory. Refer to Chapter xx for catalog part numbers.

Carbon Filter Tanks remove chlorine/chloramine from the feed water, preventing damage to the RO membrane and injury to patients. The filter incorporates a bed of granular activated carbon. Two sizes of carbon tanks come in semi-automatic control valve and exchange head styles.

WARNING:

Carbon is not regenerated and must be replaced when exhausted.

WARNING:

A suitable carbon filter should always be present as pretreatment for the RO unit in order to prevent chlorine/chloramine damage to the thin film RO membrane and harm to the patient. GE Osmonics strongly recommends the use of two carbon tanks, used in a series configuration.

Softeners remove calcium, magnesium, and other scale producing contaminants from the feed water. Their removal prevents the build-up of scale on the membrane surface. A control valve drives the regeneration of the softener, and will remove the hardness ions with a brine solution and rinse the ion exchange bed afterwards. The control valve is normally governed by a semi-automatic time clock. There are two sizes of softener tanks available.

Multi-Media Filter Tanks are a multi layered filtration system that consists of various sized rocks as the media layers. The media are selected on the basis of their size and specific gravities. Capable of removing ninety-eight percent of all particles greater than ten microns, the multi-media filter is employed to remove suspended solids and particulates from the water. The use of the multi-media filter will extend the life of the pre-filter and RO membrane. Multi-media filters are not portable and not commonly used with portable RO systems.

Dealkalizers are used to lower the pH of alkaline feed water. Water with pH levels above 8.5 with chloramines present can reduce the performance of the carbon filters and thin-film membranes. A control valve drives the regeneration rinsing of the dealkalizer. The control valve is normally governed by a semi-automatic time clock. There are two sizes of dealkalizer tanks available.
