“…Fish aquaculture wastewater affects the living organisms in the environment due to the toxic elements it contains such as N, P, Cr and Se. It also leads to an imbalance in the aquatic ecosystem (Abdelbary, 2016). With the rapid development of intensive aquaculture in recirculating systems, its impact on the environment has increased.…”

“…With the rapid development of intensive aquaculture in recirculating systems, its impact on the environment has increased. Therefore, the need to find highly efficient ways to treat the resulting wastewater so that it can be used again has increased (Abdelbary, 2016;Nicula et al, 2022). Wastewater from fish aquaculture poses a major threat to the environment, humans and economic stability.…”

“…Bioremediation may occur either automatically, or there may be a need to add materials to take place effectively, such as oxygen (O 2 ) or fertilizers, which increase the activity of microorganisms to perform their task of breaking down pollutants. The term "bioremediators" is given to the microorganisms that are used in the biological treatment process which are beneficial microbial agents and may be yeast, bacteria or fungi (Ranjan and Bavitha, 2014;Abdelbary, 2016;Aanand et al, 2017). The most important advantages of biological treatment are that it is less costly, environmentally friendly, and highly efficient in retaining the pollutants to be removed (Liu et al, 2014).…”

“…Nitrogenous substances are removed through nitrifying and denitrifying processes. they are removed from the wastewater of fish aquaculture traditionally by fluidized sand biofilters (FSB), bead filters (BF), Rotating biological contactors (RBC) or trickling filters (TF) (Abdelbary, 2016;Nicula et al, 2022). Ammonia and ammonium are toxic to fish.…”

Biological treatment is one of the best methods used to treat wastewater because it is environmentally friendly and costs less than chemical treatment methods. Experimental work was conducted to treat aquaculture wastewater and reuse it using white aggregate and gravel mechanical filter media and rice straw, activated carbon, plastic beads and banana peel as biofilter media. Factors under investigation were filter media type, ammonia (NH 3 ) concentration, HRT, measurement indicators were pH, TDS, TSS, NTU, COD, BOD, TKN. The results showed that gravel mechanical filter is better than white aggregate mechanical filter in reducing NH 3 concentration and physico-chemical parameters. NH 3 concentration in raw wastewater was 32 mg/l and reduced to 28, 25 mg/l in white aggregate and gravel mechanical filter, respectively. For gravel mechanical filter, NH 3 concentration after passing through activated carbon, rice straw, plastic beads and banana peel was 5, 9.72, 10.8 and 5.5 mg/l, respectively. Four hydraulic retention time and doses of activated carbon per liter of wastewater were used, 5, 10, 15 and 20 gm and 5, 10, 20 and 30 min. 20 min with a medium dose of 15 gm of activated carbon per liter of wastewater had the best effect on NH 3 removal. Five hydraulic retention time and doses of rice straw per liter of wastewater were used, 5, 10, 15, 20 and 25 gm and 5, 10, 20, 30 and 40 min. 30 min with a medium dose of 20 gm of rice straw per liter of wastewater had the best effect on NH 3 removal.

“…he scarcity of resources and the increase in population are the most important problems facing the world today. Therefore, aquaculture appeared to provide a source of protein for the population (Turcios and Papenbrock, 2014; Abdelbary, 2016). In recent decades, the fish farming field has witnessed significant growth (Nghia et al, 2009).…”

It will be necessary to provide about 40 million additional tons of fish by 2030 to keep the per capita share constant. Fish from aquaculture contribute about 50% of the total fish production around the world. It has become common to treat water from fish farms using the biological method, because it is one of the best methods comparinet to the physical and chemical methods. Although ammonia (NH 3 ) is one of the most important pollutants produced by fish farms, several heavy metals have serious effects on fish and the environment. In this experiment, a treatment unit consisting of two stages was designed, the mechanical filter stage as a primary treatment and then the biological filter as the main treatment stage. Gravel was used as a mechanical filter medium, while activated carbon (AC) and rice straw (RS) were used as biofilter media. The AC and RS effects on the heavy metals removal from the water were studied. Changing the pH value on ammonia removal efficiency was also produced to determine its effect. The concentrations of lead (Pb), tin (Sn), iron (Fe), arsenic (As), copper (Cu), nickel (Ni), boron (B), zinc (Zn) and cadmium (Cd) were measured for wastewater and treated water. The best efficiency of AC and RS was to remove copper (Cu) by 65.80 and 84.68%, respectively, and the lowest efficiency was to remove lead (Pb) by 31.50 and 43.20%, respectively. The best pH of AC and RS was 8 with ammonia removal efficiency of 85 and 68%, respectively.
