Abstract
The disclosed ion exchange media filter system is designed to remove NaCl (salt) from brackish water with a total dissolved solid level of not more than 3,000 parts per million. The system relies on 5 distinct zeolite and chitin Medias which are plumed so that the influent passes from the bottom of the filter to the top. The influent must be in contact with each Column of media for at least 20 minutes. The total contact time is 100 minutes. The 5 medias are as follows: 1: Column 1 & 2 are the BTEX extraction SMZ 2: Column 3 is the Chitin & Pearlite column 3: Column 4 is the Clinoptilolite Zeolite treated with HCL 4: Column 5 is the Mordinite Zeolite treated with Ammonium Hydroxide 5: Column 6 is the Clinoptilolite Zeolite treated with Fulvic Acid nI A ~ anI-eu 2?riAAcbic___ ch~ I CL(7 1iiu I I f~ g I___________chi__en {I 1 It> 3M z4oLI - -5 I ii I
Description
AUSTRALIA Patents Act 1990 Provisional Specification Improved Ion Exchange Demineralisation of Brackish Water The invention is described in the following statement Inventors: Guy Raymond Berthold David Carmody 1 Improved Ion Exchange Demineralisation of Brackish Water For many years ion exchange demineralisation systems have deionised water using various types of media contained in filter vessels, with the directional flow of water going from top to bottom. This invention has been specifically designed to employ a 5 stage in series ion exchange procedure with the influent directional flow travelling through the filter vessels from the bottom to the top. The filter vessels will be made of various readily available materials, fibreglass, fabricated steel or plastic materials. The depth of the ion exchange media has to have a minimum of 1.2 metres per column. The influent which can be demineralised has a TDS NaCl of less than 3,000 ppm. The influent must travel through the media at a velocity determined by the bed volume of media and be in contact with the ion exchange media for at least 20 minutes per column. The influent will be in contact with the 5 in series ion exchange columns for a minimum of 100 minutes enabling the ion exchange process to complete.
The media to be employed in series will be the following 1: Surfactant Modified Clinoptilolite Zeolite which will extract BTEX chemicals from the influent. 2: Chitin & pearlite media which will attract anions from the influent. 3: Clinoptilolite Zeolite treated with HCL to attract cations from the influent. 4: Mordinite Zeolite treated with Ammonium Hydroxide to attract any remaining anions within the influent. 5: Clinoptilolite Zeolite treated with Fulvic Acid which complexates with any remaining cations or anions resulting in demineralised effluent.
2 The Invention may be better understood by with reference to the illustrations of the embodiment of the invention which shows the directional flow of the influent and the valving arrangement allows for backwashing and recharging: 1: Column 1 & 2 are the BTEX extraction SMZ 2: Column 3 is the Chitin & Pearlite column 3: Column 4 is the Clinoptilolite Zeolite treated with HCL 4: Column 5 is the Mordinite Zeolite treated with Ammonium Hydroxide 5: Column 6 is the Clinoptilolite Zeolite treated with Fulvic Acid
