TY - JOUR T1 - Coflocculation of algae and clay to clarify turbid impoundments JF - Journal of Soil and Water Conservation SP - 200 LP - 203 VL - 39 IS - 3 AU - Yoram Avnimelech AU - Ronald G. Menzel Y1 - 1984/05/01 UR - http://www.jswconline.org/content/39/3/200.abstract N2 - Two pairs of comparable turbid ponds were selected to test the practicality of algal-clay Coflocculation as a means of clarifying turbid ponds. One pond of each pair was fertilized with nitrogen and phosphorus; the other was left as an unfertilized control. Algal growth was induced in both fertilized ponds, leading to a significant reduction of turbidity. The sedimentation of the algal-clay clusters removed clay, algae, and nutrients from the water column. The addition of fertilizer seems to be an efficient and economical means to clarify turbid ponds. ER -
