“…Some of the benefits of phytoremediation are potentially applicable, relatively inexpensive operating costs, capable of reducing contaminants in large volumes, and safe [9]. Several types of plants play crucial roles in waste treatment, such as water spinach [10], lettuce [11][12][13], and vetiver [14]. Chrysopogon zizanioides is a water-based land plant which is capable of absorbing soluble nutrients such as N and P and is able to accumulate heavy metals [15].…”

Liquid waste of tofu production has a high content of organic matter which can lead to a decrease in water quality. This study was aimed to obtain an optimal combination of duration and waste concentration in tofu liquid waste treatment using Chrysopogon zizanioides. Response surface method using Design Expert 7.0 software was applied to optimize combination response of duration (3, 9, 15 days) and waste concentration (20, 40, 60%), aided by Design Expert 7.0 software. The optimum treatment was 15 days with 20% waste concentration, reducing 55.48% of COD, 37.86% BOD, 93.51% TSS, 87.86% Turbidity, increasing DO to 7.2 mg/L and pH to 7.2.

“…In addition to the fish density in the fish production tank, the type of vegetable used in aquaponics interferes with the performance of Nile tilapia when produced in an NFT aquaponic system (Effendi et al, 2017). This is due to the efficiency of the plant to absorb the nitrogen compounds produced by fish.…”

The objective of this study was to evaluate the performance of Nile tilapia and the lettuce, watercress, and arugula vegetables in a gravel-bed aquaponic system using the aerated fish tank-to-vegetable growing bed volume ratios of 1:1 and 1:2. Each experimental unit consisted of an aquaponic module composed of two containers: one to allocate the vegetables (500-L tank with gravel, measuring 2 m2) and another to stock fish at the ratios of 1:1 (500-L vegetable:500-L fish tank) and 1:2 (500-L vegetable tank:1000-Lfish tank). The experiment was laid out in a randomized-block design with two treatments (500-L fish tank × 1000-L fish tank) and three blocks (periods). The performance of the Nile tilapia and of the vegetables did not differ significantly in response to the increasing fish tank volume, with the fish and the vegetables exhibiting good performance results in both volume ratios. In conclusion, in aquaponics, the fish tank-to-vegetable tank volume ratios of 1:1 and 1:2 are equally effective for the production of Nile tilapia and the lettuce, watercress and arugula vegetables.

Summary Most recirculation aquaculture systems (RAS) use aerated biofilters to maintain suitable water quality for fish production. However, application of non-aerated biofilters may provide opportunities to lower aeration costs, water usage and concentration of all nitrogenous wastes in the effluent water. Our study aimed at comparing the biofiltration performance characteristics of two biofilters: a conventional aerated biofilter and a non-aerated biofilter receiving the same effluent water from a small-scale RAS. The two biofilters were evaluated in triplicate and tested concurrently for seven months. Water quality parameters were monitored at the biofilter inlets and outlets and in the fish tanks. At the beginning of the experiment, the concentration of ammonia at the two biofilter outlets were not significantly different. However, the concentrations decreased with time reaching mean values of 1.33 ± 0.02 mg L−1 and 1.23 ± 0.21 mg L−1 N-NH4 in the aerated and non-aerated biofilters, respectively. Whereas phosphorus and nitrate levels were significantly high in the aerated biofilter. There was no significant difference in the growth of fish between the aerated and non-aerated biofilters. The results suggest that non-aerated biofilters can be as effective as aerated biofilters in maintaining suitable water quality for O. niloticus production.
