Abstract Saline effluents from marine land-based aquaculture production can neither be disposed in common municipal wastewater treatment plants, nor as landfill. Furthermore, stricter environmental regulations require the reduction of phosphorous and organic matter levels environment discharges to minimize eutrophication. Chemical coagulation with FeCl3 AlSO4 is commonly used for removing suspe...

A recirculating aquaculture system (RAS) can reduce water and land requirements for intensive production. However, a traditional RAS uses fixed circulation flow rate treatment. In general, the in an is highly turbid only when animals are fed they excrete. Therefore, quality regulation technology based on process control proposed this paper. The intelligent variable-flow was designed circulating...

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...
