M900 - AquaClave RO P5

The AquaClave M900 Series remains the proven 5 stage AQUALIFE RO system but with an enhanced production capacity.  Sufficient water to feed thermal washer disinfection and steam sterilisation equipment.

The M900 includes a larger capacity membrane, double ended high flow pump, a 40 litre storage tank or with an 80 litre tank option plus all the enhanced features of the standard AquaClave system.

The AquaClave M900 series model has a high capacity membrane with excellent abrasive resistance.  The membrane will remove approximately 95% of all dissolved minerals and salts.  The two-stage polishing system feeding the AutoClave will remove remaining organic and non-organic residues thereby finishing the water quality to meet all AutoClave operating standards.  The water for the thermal washer by-passes this final treatment and is supplied direct from the membrane.

The availability of this volume of water enhances the economics of your investment and makes your choice of an AquaClave M900 series an intelligent decision.

What is Reverse Osmosis? Reverse Osmosis was originally designed to make sea water drinkable for the US Navy. Reverse osmosis is the reversal of the natural flow of osmosis. In a water purification system, the goal is not to dilute the salt solution, but to separate the pure water from the dissolved salts and other contaminants. When the natural osmotic flow is reversed, water from the salt solution is forced to pass through the membrane in the opposite direction by application of pressure, thus the term REVERSE OSMOSIS. Through this process, we are able to produce pure water by screening out the salts and other contaminants.

The other important function is to reduce the chlorine and organic content of the feed water. 6 Months STAGE 2 P/N WC 1025Q PRETREATMENT The purpose of this high performance carbon filter is to further remove free chlorine and organic content of the water. It completes the 2 stage pre-treatment of the feed water supply. 6 Months STAGE 3 P/N WC 1016DD RO TFC MEMBRANE This specifically engineered high volume production capacity with high rejection TFC membrane is manufactured in the USA. The membrane removes approximately 99.99% of all dissolved minerals and salts present in the feed water supply. Production and performance will be influenced by the chemical analysis of the water supply. 2 - 3 years STAGE 4 P/N WC1011A POST CARBON FILTER: ORGANIC ZAPPER NSF approved. This post membrane carbon filter is designed to remove organic residue. It removes residual impurities and odours from the tank and provides a finer conditioning of pure water. 6 Months STAGE 5 P/N WC 1025C NON-ORGANIC POLISHING CARTRIDGE This final process addresses all non-organic residue leaving a quality of water that complies with AS 2182 1998 Appenix C Quality of Feed Water for Steam Generation when the system is operated in accordance with this manual. 6 Months 1 2 5 9 Parts Identification 1st Pre-Filter Housing 2nd Pre-Filter Housing 5th Final Polishing Filter RO Membrane Pump Inlet Feed Water Auto Flush Panel To Faucet 1 1 1 6 6 2 2 7 8 8 5 5 RO Membrane Housing Post Carbon Filter RO Membrane Pump Auto Flush Panel To Tank 6 3 8 4 9 10 5 2 6 4 8 3 9 10 7 10 Steam Steriliser Operation; AquaClave® Plumbing Diagram When the RO system is installed a 1/2” brass tee is cut into the water supply line and a 1/2” to 1/4” 500kPA Pressure Limiting Valve and a 1/4” stop tap fitted. The 1/4” plastic hose is connected and leads to the inlet on the front of the 1st Housing which has a plastic tee with the other side of the tee going to a low pressure switch. The hose from the elbow at the rear of this housing runs from the inlet solenoid to the pump. The outlet of the pump is attached to the elbow at the rear of the 2nd housing with the outlet from this housing going to the elbow on the inlet of the membrane housing (the end with the cap). Water passes through the membrane to 2 outlets in the housing. 1. One leads to a tee and through a High Pressure Switch to the inlet of the Zapper and the other side of the tee goes to the tank. 2. The other outlet is the reject water to the drain via a 400 Flow Restrictor. The Flush Solenoid allows a diversion around this Flow Restrictor when the system is in flush mode. The Product Water passes through the Zapper to the inlet at the front of the 3rd housing. From the elbow at the rear of this housing, Product Water goes to the Faucet and/or Autoclave. When the tank is full, the system automatically shuts down until Product Water is required and first flushes to the drain thus clearing the membrane of fouling material.
