mechanical/physical/solid, chemical and biological filtration devices (or a combination of two or more different types):
biological filter:
is part of an RAS where dissolved metabolic by-products are converted to less toxic forms by microbial action from a range of different bacteria, fungi and other microorganisms
the most important function is the oxidation of ammonia to nitrite, and nitrite to nitrate (often called nitrification)
chemical filter:
examples include activated carbon, zeolites and other ion-exchange mediums
is where a variety of chemical substances are used to treat water passing through them
ozone and chemical, such as pH and alkalinity, adjustments are also made, sometimes in a separate area to the chemical filter
mechanical/physical/solid filter:
includes swirl separators, hydrocones, protein skimmers or foam fractionators, drum filters, belt filters, bead and other suspended media filters and screen filters
is important to ensure organic loads going into biofilters are as low as possible to prevent the more competitive heterotrophic bacteria from taking over and reducing nitrification capacity
is part of an RAS that removes solid organic matter and other wastes
reduces the biological oxygen demand (BOD) for the system
some degassing or carbon dioxide stripping can also take place
ventilation systems, fans, blowers and humidifiers/ dehumidifiers
water treatment devices, such as those that maintain pH (acid/alkaline) balance.

a system in which at least some of the water is recycled one or more times back into the system after some form of treatment
also called a closed system (which is the opposite to a flow-through or open system where there is little residence time for the culture water)
