How should one choose wastewater treatment for aquaculture?
First, the characteristics of aquaculture wastewater are:
It contains a high amount of suspended solids,along with undigested feed,
and fish feces.Additionally, it often has excessive nitrite levels.When selecting aquaculture wastewater treatment equipment,we primarily follow a three-step approach:
The first step is physical interception.The wastewater first entersa microfilteror a protein skimmer.During this stage,feed particles and fish feces are separated,ensuring the stability of subsequent treatment systems.Second, it prevents clogging—pumps and other equipment remain unobstructed.Secondly,through the biological system behind me,we employ an MBBR biological aerated filterfor biochemical treatment.During this process,ammonia nitrogen and nitrite in the wastewaterare treated here.Through our biological processusing MBBR media,
this media featuresa large specific surface area,supporting abundant microbial colonization
and high biological treatment efficiency.After processing through this system,we ensure our treated wastewater meets standardsand clarity.Subsequently, considering the potential presence of pathogens, bacteria,
viruses, and similar contaminants in aquaculture water,a disinfection stage will be added downstream.
For disinfection,we primarily employ physical methodssuch as ultraviolet (UV) disinfection or ozone disinfection.Through these two disinfection stages,we can effectively eliminate viruses and bacteriain the incoming water.
