Project Description

Prestige Descale

A compact RO unit with integrated pre-filtration that accommodates a higher level of output.

The Prestige Descale is combined with pre-treatment and feed water break tank, as appropriate to the needs of the customer.

5μm pre-filter: Protects reverse osmosis (RO) membrane from fouling by particulates and colloidal contaminants found in mains water.

Internal break tank: Protects against feedwater pressure fluctuations and allows easy cleaning.

Integral boost pump: Enables RO membranes to operate at optimum performance.

Permeate divert: Ensures consistent permeate quality.

RO membrane: Removes up to 98% of dissolved minerals, and up to 99% of organic, bacterial and particulate contaminants.

Automatic membrane concentrate flush: Extends membrane life.

Product control selection: Allows continuous running or control via external tank level sensors.
