3.3. PO4-P removal efficiency from wastewater
In this aquaponics, PO4-P removal was observed from 58.14%
(control) to 74.83% (50% wastewater) (Fig. 2). The removal followed
the order – 50% wastewater > 100% wastewater > 75% wastewater
> 25% wastewater > control (Fig. 2). This removal in 50%, 75% and
100% wastewater and in 25% wastewater and control was the same
(one way ANOVA, P > 0.05), though the strength of wastewater
