A parallel waterway test was conducted to verify the ability of zeolite rocks, shell-bearing clastic rocks and woody biomass chips containing ferment bacilli to remove T-N, PO4-P and other physicochemical pollutants from water. Zeolite rocks from Tan-no Town in northeastern Hokkaido consist predominantly of heulandite-clinoptilolite series minerals and lesser quartz, plagioclase and opal-CT. The cation-exchange capacities (C.E.C.s) of zeolite rocks ranged from 170-176 meq/100g. Commonly occurring shell-bearing clastic rocks from Akan Town in eastern Hokkaido are dominantly calcite with lesser quartz, plagioclase, smectite, heulandite-clinoptilolite series minerals, gypsum and pyrite. The C.E.C. of shellbearing clastic rocks was 39 meq/100g.
The results of this parallel waterway test clearly demonstrated that the zeolite rocks, shell-bearing clastic rocks and woody biomass chips were effective for removing of PO4-P, NH4-N, NO2-N, NO3-N, T-N, COD and BOD from the river water.
