Description

The moving bed biofilm reactor using sponge media has characteristics such as that can be operated with high load BOD and easy maintenance. Pilot plant tests using this reactor were conducted for paper mill wastewater treatment. And so the performance of full scale moving bed biofilm reactor using sponge media was investigated, modifying an existing paper mill wastewater treatment plant.<BR>In the pilot plant test, S-COD was removed over 65% at COD volumetric loadings below 4kg⁄ (m3•d) , and S-BOD was removed over 90% at BOD volumetric loadings below 3. 5kg⁄ (m3•d) . The moving bed biofilm reactor using sponge media showed high performance of organic removal. Furthermore this pilot plant effluent COD was removed about 80% by chemical precipitation test, conducted with the addition of 200mg⁄L as Al2 (SO4) 3•18H2O and 1mg⁄L as anion polymer at pH6. These results show that soluble and particle organics is removed effectively by combined process of moving bed biofilm reactor and chemical precipitation.<BR>In the full scale moving bed biofilm reactor, S-COD was removed over 70% at S-COD volumetric loadings below 2kg⁄ (m3•d) , about 60% at S-COD volumetric loadings of around 3kg⁄ (m3•d) , and S-BOD was removed over 90% at S-COD volumetric loadings below 2. 5kg⁄ (m3•d) . Performance of full scale plant was higher than designed value with 60% S-COD removal at S-COD volumetric loadings below 2. 5kg⁄ (m3•d) <BR>These results show that high organic load treatment is achieved with the moving bed biofilm reactor using sponge media for paper mill wastewater, and this reactor is effective for improvement of existing plant.
