This study was conducted in order to compare the hornwort aquatic plant (Ceratophyllum demersum) with an artificial filter for purification in a recirculating aquaculture system (RAS). At first, the fluctuation of nitrogen components of the water reuse system equipped with artificial filtration was evaluated. Experiments were performed during three months. The hornwort aquatic plant was collect...

Users of motorized vehicles in the city Pontianak are growing rapidly. For some people who very busy washing motorbikes is a tiring thing and usually, take their to car wash. During this time, motorcycle providers directly dispose waste into environment, which causes pollution environmental damage. The technology used treatment system based on natural materials (biofilter). method activity an e...

A novel alum sludge-based odor-gas aerated vertical flow biofilter (Al-OAF) was developed, which aims to removal the pollutants in wastewater and simultaneously eliminate H2S generated from treatment facility. Three lab-scale parallel columns were operated batch model while intermittently with 200 ppm (Al-OAF), air (Al-AF) unaerated (Al-F, as blank), respectively. The effluent concentration Al-...

Abstract Biofilter is the core unit of recirculating aquaculture system(RAS), which mainly to achieve in situ purification and restoration water pollutants by enriching microorganisms on biofilters form biofilms. To explore changes metabolic characteristics microbial communities process biofilm formation RAS under low-temperature environment, 16S rRNA high-throughput sequencing was applied anal...

Plastic media trickling biofilter technology is being used on a pilot-scale to treat swine lagoon wastewater for use in a hydroponic greenhouse system. Two treatments of 9 filters each were installed to compare the treatment performance of commercially available BioballsTM and recycled soda six-pack rings and to verify a mathematical description of nitrification in a trickling filter. Determini...

Swine (Sus scrofa) slurry stored in open storages is a source of airborne contaminants. A customary practice for ammonia and odor control consists of covering the surface of the slurry with floating materials, such as straw. Although straw covers have been proven to generally reduce gaseous emissions, more knowledge is needed regarding how age, moisture content, and microbiological development ...
