Some issues with aquaculture have progressively started to come to light, as a result of the on-going improvement of aquatic product quality and safety criteria, and the constant focus on the standardisation of aquatic product sources.
The water environment of aquaculture has been severely impacted by issues, such as the deterioration of aquaculture species, excessive aquaculture density, and arbitrary discharge of sewage and wastewater, which has also ruined the regional ecological balance.
Therefore, finding suitable treatment technology and recycling the wastewater, from industrial aquaculture after treatment are efficient ways, to address the potential environmental concerns and make full use of wastewater resources. So, how should we handle and treat aquaculture plant wastewater?
How to treat of wastewater in aquaculture plants?
Let's examine the following techniques:
· Physical processes
Filtration, separation, neutralisation, precipitation, adsorption, and other processes are the key components of the physical treatment approach. Large suspended particles and a portion of COD in aquaculture wastewater are removed by it.
Studies have demonstrated that the reverse osmosis and ultrafiltration membrane systems, have a clearance rate of more than 90% of all bacteria. This means that it satisfies the criteria for reuse in aquaculture.
The process for the reuse of aquaculture wastewater is as follows:
1: Aquaculture wastewater-first level sedimentation tank, tank for pure water oxidizer, tank for insulation system for pretreatment and fine filtering.
2. To treat aquaculture wastewater and lessen membrane pollution, this process route first undergoes fine filtration, which improves the effluent quality.
3. With high removal efficiency and ease of use, Netsol Water Solutions’ offers a variety of reverse osmosis solutions, which are appropriate for pre-filtering aquaculture effluent.
· Use of Chemical processes
In order to degrade and transform pollutants into non-toxic and harmless substances, or to prevent the generation of pollutants by chemicals as the main component, the method uses the process of chemical reactions between chemicals as well as the pollutants.
Ozone treatment technology is currently the most used chemical technique, both domestically and internationally. Ozone has a good bactericidal impact in addition to being able to eliminate some harmful compounds. It can also lower the concentration of suspended particles and COD in aquaculture wastewater, and restrict the growth of fish pathogenic microbes, oxidised organic matter, nitrogen elements, and other dangerous chemicals.
· Using Microbial Process
Researchers have discovered that microorganisms may dissolve the polluted sediment, of about 4 cm at the bottom of the fish pond in about 30 days, after studying helpful microorganisms to improvise ecology in aquaculture sector, as well as to promote growth of microbial decomposition.
