Biomass and microbial activity in a biofilter during backwashing.
Biomass and microbial activity in backwashing processes of a biofilter for tertiary treatment were investigated. The microbial groups revealed new distribution along the biofilter depth after low flow rate backwashing for a short time. Then the start-up process was accelerated by backwashing. The biomass profile and microbial activity profile both varying with depth before and after backwashing...
متن کاملMicrobial Removals by a Novel Biofilter Water Treatment System
Two point-of-use drinking water treatment systems designed using a carbon filter and foam material as a possible alternative to traditional biosand systems were evaluated for removal of bacteria, protozoa, and viruses. Two configurations were tested: the foam material was positioned vertically around the carbon filter in the sleeve unit or horizontally in the disk unit. The filtration systems w...
متن کاملEffects of oxygen concentration on microbial growth in aerated palm oil mill effluent using oxygen enriched air membrane system
Aeration is one of the most important factors in biological wastewater treatment process. Through aeration, oxygen is supplied to the bacteria to allow their respiration to proceed rapidly and satisfy the biochemical oxygen demand (BOD). This study was carried out to determine the biological growth in aerated palm oil mill effluent (POME) when subjected to aeration using air of different oxygen...
متن کاملThe Growth of Brucella in Aerated Liquid Cultures.
Studies conducted on the immunochemistry of members of the genus Brucella required the growing of comparatively large amounts of these organisms in liquid culture medium. The production of a culture which would retain its full virulence over a period of six months was one of the major requirements of our work. Very little information on the growth requirements of Brucella was available in the l...
متن کاملGrowth of indigenous organisms in aerated filtrate of feedlot waste.
Filtrates from feedlot waste were incubated under aerobic conditions to evaluate the availability of nutrients for cell production and to assess the capacity of indigenous flora to produce stabilized effluents. Incubation was carried out in 9-liter aerated jar fermentors. Three-fourths of the organic material and one-third of the nitrogen were taken up in 4 days; 90% utilization of organic mate...
