The research aims to assess the ability to treat slaughterhouse wastewater by using biofilter at one small slaughterhouse in Ben Tre province.The research was conducted by building a biofilter tank model and observing the formation of biofilm.The treatment capacity of pilot model was explored and evaluated using iphone 14 price texas four different parameters including: TSS, BOD, N-NH+4, Turbidity.The findings showed the best treatment capacity of TSS at 78.93%, BOD at 88.
77%, N-NH +4 at 87.50% grand love red heart reposado tequila and turbidity at 96.61%.However, the concentration of BOD, TSS, and Ammonia at the biofilter outlets is still higher than the values regulated in the National Technical Regulation on Industrial Wastewater of QCVN 40-2011/BTNMT.Therefore, biofilters should only be applied as a pretreatment step and the wastewater need to be further treated.
