摘要：

In this study, the flocculant behavior of Malva sylvestris (mallow) and Hibiscus esculentus (okra) mucilages was assessed for the removal of turbidity from synthetic and biologically-treated effluent. A series of flocculation experiments were conducted to assess the optimal concentration of each species. Aluminum salts were used as coagulants. The results showed that mallow and okra mucilage have significant flocculation properties. It was determined that okra was as efficient as mallow in removing turbidity. at at higher dosages the DOC of both synthetic wastewater and effluent increased. However much lower doses,. probably due to the organic substances present in the okra and mallow mucilage, (C) 2009 Elsevier B.V. All rights reserved.
