    Abstract - (Show below) - (Hide below)

    CONTAINED IN VOL. 11.02, 2015 Defines the calculation and adjustment of silica (SiO[2]) for the concentrate stream of a reverse osmosis system.

    Scope - (Show below) - (Hide below)

    1.1This practice covers the calculation and adjustment of silica (SiO2) for the concentrate stream of a reverse osmosis system. The calculations are used to determine the need for scale control in the operation and design of reverse osmosis installations. This practice is applicable for all types of reverse osmosis devices (tubular, spiral wound, and hollow fiber).

    1.2This practice is applicable to both brackish waters and seawaters.

    1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
