Note:
Additional floor space will be required for an oxidant storage tank, brine generator, water
softener, brine pressure boost system, and depending on the installation, salt storage. Additional
floor space will also be required for the injection system and additional booster pumps
Security
MIOX equipment must be installed in a building or protected structure that provide shelter
from the weather and extreme temperature variances, and which can be locked or
otherwise secured. Physical security is required to ensure that unauthorized persons
cannot access the unit
RIO Series OSG System and Ancillary Components
Electrolytic Cell
The proprietary membrane-less electrolytic cell produces a mixture of oxidants and is
manufactured by MIOX. The RIO Series cell is configured to provide modular cell capacity
depending on the disinfectant requirement. Each MIOX cell module is configured to provide
60 lb/day Free Available Chlorine (FAC), while each HYPO cell module is rated to provide
100 lb/day FAC. Each cell can be configured from a single cell module (60 or 100 lb/day
FAC) up to a 5-module (300 or 500 lb/day FAC) cell.
The electrolytic reaction that takes place within the cell occurs under pressure (5-25 psi, 34-
172 kPa). The cell is equipped with a rupture disc (pressure relief port) that is designed to
rupture in the event of over-pressurization within the cell.
Water Softener
All MIOX equipment requires soft water. Hard water will cause severe damage to the cell.
Water hardness must be maintained at
less than one grain/gallon (17.1 mg/L of CaCo
3
).
The softener resin is recharged with brine from the brine generator. The correct sized
recharge meter disc is determined by water hardness.
Brine Generator
The capacity of brine generators ranges from 500 lb., manually loaded systems, to 160,000
lb. systems, pneumatically loaded from a transport truck. A mechanical float valve assembly
which monitors the brine level is included with the brine generator.
Oxidant Storage Tank
The oxidant storage tank is an integral part of an on-site generator, and is sized to meet the
injection demand at the peak hourly flow. The oxidant tank must be vented directly to the
atmosphere outside the facility.
Brine Pressure Boost System
A brine pressure boost system insures that sufficient brine pressure is supplied to the brine
metering pump to maintain optimal cell operation amperage. A separate electrical circuit is
required for the brine boost system.
