We propose a regularization for reduced-order models (ROMs) of the quasi-geostrophic equations (QGE) to increase accuracy when the proper orthogonal decomposition (POD) modes retained to construct the reduced basis are insufficient to describe the system dynamics. Our regularization is based on the so-called BV-α model, which modifies the nonlinear term in the QGE and adds a linear differential filter for the vorticity. To show the effectiveness of the BV-α model for ROM closure, we compare the results computed by a POD-Galerkin ROM with and without regularization for the classical double-gyre wind forcing benchmark. Our numerical results show that the solution computed by the regularized ROM is more accurate, even when the retained POD modes account for a small percentage of the eigenvalue energy. Additionally, we show that, although computationally more expensive than the ROM with no regularization, the regularized ROM is still a competitive alternative to full-order simulations of the QGE.

. This study aims to explore the potential use of electro-oxidation (EO) as a decentralized wastewater treatment method. The simulated wastewater comprising bacterial consortium was treatedbyemployingmixedmetaloxide(MMO).Inparticular,alab-scalebatchelectrooxidationreac-tor was used at di ff erent operating parameters including NaCl dose ( n ), current density ( j ), and treat-ment time ( t ) in order to optimize the process using response surface methodology. The e ffi ciency of the treatment process was evaluated in terms of % inactivation and energy consumption which were found to be 99.2% and 0.42 kWh/m 3 , respectively. Under optimal conditions, it was found that the proposed technique’s overall operating cost was 0.189 $/m 3 taking into consideration the electrical energy consumed and cost of electrodes.
