Journal AWWA - Developing a Sand-GAC Filter to Achieve High-Rate Biological Filtration AWWA杂志-开发砂GAC过滤器 以实现高速生物过滤
发布日期: 1988-12-01
法国研究了一种将沙子和颗粒活性炭(GAC)结合起来并保持生物处理机制的单层双层过滤器,作为实现高速过滤的可能方法。初步结果证明,双层砂单元远远优于单层砂单元,尤其是在去除悬浮固体和氨方面。在双层过滤器的顶层使用GAC可确保去除大量可吸收碳,从而对最终氯化和水的适口性产生积极影响。包括13个参考文献、表格、图表。
A single dual-layer filter, combining sand and granular activated carbon (GAC) and maintaining the mechanisms of biological treatment, was studied in France as a possible means of achieving high-rate filtration. Initial results attest that the dual layer far outperforms a single-layer sand unit, particularly with respect to the removal of suspended solids and ammonia. Using GAC for the top layer of the double filter ensures the removal of appreciable quantities of assimilable carbon and consequently has a positive effect on final chlorination and the palatability of the water. Includes 13 references, tables, figures.
