The characteristics of palm oil mill wastewater (POMW) were brown color, pH 3.8-4.3, temperature 48-55oC, total solids 68.2-82.1 g/l, suspended solids 26.2-65.6 g/l, oil and grease 19.1-25.1 g/l, COD 49.9-160.7g/l and BOD 32.5-75.3 g/l.After centrifugation (3,184 xg) of 50 ml POMW for 10 min, the POMW was separated into 3 layers: top (oil), middle
We have previously shown how stereoscopic images can be obtained in our three-dimensional optical micromanipulation system blouse [J.S.Dam et al., Opt.Express 16, 7244 (2008)].Here, we present an extension and application of this principle to automatically gather the three-dimensional coordinates for all trapped particles with high tracking range a
