                Manz Slow Sand Filter™(MSSF)
 
                The MSSF meets or surpasses the well-established 
                ability of the Traditional Slow Sand Filter (TSSF) to remove pathogens (parasites, spores, bacteria and viruses).    
                 
                The MSSF is a novel 
                variation: |  | Manz 
                Polishing Filter™(MPSF)
 
                The MPSF exploits 
                the unique ability of TSSFs to remove small particles. 
                Construction and operation of MPSFs are similar to MSSFs with all 
                of the same advantages. 
                Ease of cleaning allows  MPSF based water treatment systems to remove: 
                  
                
                Sand, silt or 
                clay
                
                Manganese, iron, 
                arsenic, fluoride, or heavy metal
                
                TOC/DOC and Algae 
                and treat water
