Most of the chemical waste treatment methods use some form of precipitation technology to remove the heavy metals, which are the primary problem species. After precipitation, the slurry is allowed to settle, and the thickened solids are dewatered by using mechanical devices such as filter presses or centrifuges. Bell has reviewed treatment methods for treating many types of wastes. Spent mineral... 

Figure 5 Contour plot of the NOESY spectrum at 360 MHz of the basic pancreatic trypsin inhibitor. The protein concentration was 0.02 M, solvent D2O, pD = 3.8, T = 18°C. The spectral width was 4000 Hz 512 data points were used in each dimension 56 transients were accumulated for each value of U. The mixing time was 100 ms. The absolute value spectrum, obtained after digital filtering in both dimensions with a shifted sine bell, is shown. NOE connectivities for selected amino acid residues are indicated by the broken lines.
