An aeration tank needs to be installed for the removal of VOC from water, where the required rate of flow of water through the aeration tank is $180,000 \mathrm{~m}^{3} / \mathrm{d}$. Permissible limit of VOC in the water is $12 \mu \mathrm{g} / \mathrm{L}$. The saturation concentration of $\mathrm{VOC}$ is $5 \mu \mathrm{g} / \mathrm{L}$ and gas transfer rate constant is 0.40 per second at $25^{\circ} \mathrm{C}$. The initial concentration of VOC in the water is $33 \mu \mathrm{g} / \mathrm{L}$. The volume of the aeration tank to satisfy the permissible limit of VOC at $25^{\circ} \mathrm{C}$ is _________ (in $\mathrm{m}^{3}$, $\text{rounded off to two decimal places).}$
