ABSTRACT

The Intermunicipal Water Company of Veurne-Ambacht (IWVA) started reusing wastewater effluent for infiltration in its dune water catchment, St-André, in 2002. The treatment train at the Water Production Centre Torreele is based on a multiple-barrier approach with submerged ultrafiltration prior to reverse osmosis. The project improved the ecological values of the dunes. Recently, during longer periods of drought, the combination of reuse and managed aquifer recharge proved more robust than conventional drinking water production sites: groundwater levels at St-André remained high enough to ensure drinking water production and protect its quality. IWVA’s experience shows that water reuse can help mitigate the impact of climate change.

摘要

Veurne-Ambacht的市政水务公司（IWVA）于2002年开始在其沙丘集水区St-André重复利用废水进行渗入。托雷雷尔水生产中心的处理系统基于浸没式超滤的多重屏障方法在进行反渗透之前。该项目提高了沙丘的生态价值。最近，在更长的干旱时期，再利用和管理的含水层补给相结合被证明比传统的饮用水生产地更坚固：圣安德烈的地下水位仍然足够高，可以确保饮用水的生产并保护其质量。IWVA的经验表明，水的再利用可以帮助减轻气候变化的影响。
