The Aquamarine range of Reverse Os-mosis systems is a comprehensive range of standard and customised products developed and manufactured in South Africa on the basis of the well-known process of Reverse Osmosis which has been under constant development since the first experimental systems were introduced in the 1950’s. In general terms the process is a “reverse process” based on the natural osmotic pressure difference between two salt solutions on either side of a membrane, in which mechanical pressure is applied to the side with higher salinity.

The membranes through which the salt passes at relatively high pressure are a vital part of the system, separating the fresh water from the “salty” or undesired water.

All Aquamarine systems use high qual-ity “thin film composite” spiral wound membranes housed in fibreglass rein-forced plastic or FRP pressure vessels. The operating processes are continually monitored and controlled by sophisti-cated PLC and microprocessor control-lers which will give immediate warning and possible shut down if any of the vital process parameters are not within ac-ceptable limits.

All systems have the option of a dosing pump to dose one of the many AQM membrane anti-scaling chemicals that will be customised as per the feed wa-ter conditions.

All pumps and instrumentation is of top quality which is vital to ensure reliability and long service life, with a minimum of maintenance required. The electrical and control logic is an inte-gral part of the system which will ensure long, trouble free operation of the sys-tem. The system includes all necessary instru-mentation including: • Flow meters for indication of fresh water and brine water outlet flows. • Glycerol filled pressure gauges for pressure indication. • Conductivity monitoring with warning and optional shut down for water quality management. • Pressure switches for protection against over and under pressure. • Float switches for system automa tion in relation to tank levels.

All frame work is epoxy coated mild steel and interconnecting pipework and fit-tings are either CL16 PVC or stainless steel for corrosion resistance.
