Micro-Pac (Patent No. 2007/06988)

TheMicro-Pac is fitted with a 12 V DC pump which enables the Micro-Pac todeliver on average a flow rate of 2 litres per minute. The pump isfitted with a high pressure cut off switch to protect the motor. Thiswill make the pump cut out if the pressure in the system reaches 250kPa. . A pressure gauge is fitted to the unit in order to assist theuser in determining when the cartridges need to be either replaced orcleaned.

Thesecond cartridge that is used is a sliver impregnated ceramic microfilter. This is the sterilizing component of the unit. This filterremoves particles down to 0.8?m, 99.99% of bacteria are eradicated oncethey come in contact with the silver that is locked into the ceramic.Examples of these bacteria are E-Coli, Cholera, Shigella, Typhoid andKlebsella. Other harmful cysts are removed, like Cryptosporidium andGiardia, these are the generally the cause of the tummy bug or betterknown as travellers diarrhoea. This cartridges recommended lifespan is10 000 litres, it will however need a clean from time to time dependingon the water source. 

The unit comprises of two filters, the first being an activated carboncartridge. This cartridge has a pre-filtering property to remove allsuspended solids bigger than 5?m (5x10-6mm). The second property ofthis initial cartridge is the carbon block situated in the core.Activated carbon is used to remove the traces of organic odours andtastes from surface water and chlorine from municipal supply. Thisfilter is estimated to have a life span of 10 000 litres if thechlorine content of the water is 2 ppm maximum, the figure of 10 000 lis relative to the quality of the source water.

TheMicro-Pac is a mini, transportable water purification unit. It is achemical free process using proven technology to purify any surface andtap water. The unit is housed in a standard ammo box, roughly 500mm x400mm x 230mm and weighing approximately 8kg.
