Figure 4From: Effect of organic matter on estuarine flocculation: a laboratory study using montmorillonite, humic acid, xanthan gum, guar gum and natural estuarine flocsThe median floc diameter is shown as a function of salinity for three overlapping ranges of organic matter loading (i.e., TOC = 0 – 5, 2 – 11, and 5 – 20 mg L1-). The data for the size of organic matter-free flocs are shown using red x’s for comparison.Back to article page
