Opportunity : Further to as illustrated in 276) and 307)

              innovative way of designing water filter or bed is

              a concentric twin Hallow drums (refer to any standard candle based
              water purifiers available in the market) ...fill rather stuff
              one layer with ash from dung and one layer with sand ...wrap the
              candle with a disposable cloth  ....pump water into the center of the
              candle ....boil or treat with UV  

              [in the above the bed can also be manufacture by using ....layers of
               ...sewerage  containers (in telugu refer to water are termed as jalleyda
               viz. or sewer's(containerr) sewing atta to obtain finely grained poweder,
               filled with above material ]
               

              ....a highly safe consumable water.


              Also ....if one understands how traditionally water stored in earthen
              pots (mud (pottery)  gets cooled [....by making the earthen ware a 
              little bit more porous]
              or developing a candle using a mud ...and pumping water into candle with
              pressure .....should .....provide ....water ...clean from impurities

              or candles made out of mud (pottery) ...since mud is by nature absorbs
              water ....should highly purified safe ...consumable water [...optionally
              boiling ]

               By understanding the properties of a cathode-ray tube  ...viz. emission of 
               electrons ....this can be used for treating water in one of the stages of 
               purification , ...i.e. kill harmful bacteria ... algae ...fungi etc.

             ---------------------------------------------------------------------------------------------------- 

Opportunity : deriving from the aparatus used usually for plasma (human blood) segregation ...viz. ultracentrifuge ,
              a innovative water purification or treatment plant can be derived or explored.          
              
            
Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
