Aquaculture effluent treatment as reuse for purpose.Microbial bioremediation of aquaculture effluents:
Bioremediation of aquaculture effluents is performed under both aerobic and anaerobic conditions. Regarding aerobic conditions, some bacteria can perform biological nitrification; considerable amounts of oxygen are required for this.

3. Introduction
• Microbial bioremediation of aquaculture effluents:
• Bioremediation of aquaculture effluents is
performed under both aerobic and anaerobic
conditions. Regarding aerobic conditions, some
bacteria can perform biological nitrification;
considerable amounts of oxygen are required for
this.
4. Managing aquaculture effluent
• Recirculating Aquaculture System (RAS) it is always
important to remember that regardless of how
much you want to recycle the water stream, there
are always effluents to consider specifically, from
the mechanical filter backwash and potentially
biofilter backwash. All of the unconsumed food
along with the fish excrement needs to be dealt
with but regularly we forget about this part of the
process because it is, in reality, a fairly small
component of the overall mass balance.
5. Developing Treatment
• Current and developing treatment technologies for
aquaculture effluent its nature, aquaculture
requires volumes of waters for its culture; hence, a
substantial amount of wastewater is discharged
into water streams. Aquaculture effluent treatment
is normally based on the culture system in
question. It is discussed further in the following
section and is separated into two sections focusing
on current practices and technology at the
development stage.
6. Distributed effluent Treatment
• Conventional effluent treatment systems are
typically based on a series of water treatment
facilities in which all the wastewater collected from
water-using operations is combined and treated as
a single effluent stream. This centralised approach
treats wastewater collectively in sequence. For
example, the combined effluent is first treated by a
primary treatment unit, which is then dealt with by
a secondary treatment unit.
