Abstract:
Sustainable wastewater treatment is getting more attention nowadays worldwide. Researchers have been looking for cost-effective and environment-friendly technologies at the same time. Fishery industry preside an important role in wastewater production. Nitrogen discharge limit is very high in fishery wastewater because of the regular fish-food leftover and wastes from fish. Normally, different types of commercial biofilter media used in fishery water treatment which is available in the market. Coral, pumice, bio-ball, bio-glass and plastic media is common biofilter media that showed good result. Coral reef is an important biological diverse and valuable for ecosystem. But it is still being used illegally as a filter material in water treatment process for fisheries industry in a large amount because of its effectiveness in nitrogen compound removal. In this study, different types of biological filter media were used to host and grow nitrifying bacteria. The media made from biomass ash, rice husk ash and coal bottom ash were tested in laboratory water treatment units in comparison with commercial media in terms of nitrogen compound removal. Under a given test condition of water temperature ranging from 26 °C to 28 °C and DO >4.00 mg L-1 , the media made from biomass ash showed superior removal ofnitrogen compounds and the toxic nitrogen wastes were removed earlier. In addition, scanning electron microscopic examination revealed that microstructural features of these media were suitable for growth of nitrobacteria, leading to improving nitrification performance.
