WebDESWATER WebAnother important aspect of TSS analysis is the filtration apparatus. EPA method 160.2 requires that all filtration apparatus be fitted with a coarse (40-60um) fritted disk. Standard Methods requires only a filter apparatus with a reservoir to have a fritted disk. The fritted disk is a porous glass disk used to support the filter paper.

WebTotal solids may be differentiated according to size into total dissolved solids (TDS) and total suspended solids (TSS; see Figure 15.7). Once again, this is an operational distinction, whereby all solids passing through filter paper of a certain pore size (e.g., 1.5 microns, Whatman #934AH) are called dissolved, and those retained are termed suspended. Webman GFF glass fiber filters with a nominal pore size of 0.7 µm. The filters were pre-ashed at 450°C for 1 h (see step 1 in the flowchart in Fig. 1), gently washed in 0.5 L of MilliQ water (2) to remove friable fractions that can be dislodged during filtra - tion, dried at 75°C for 1 h (3), pre-weighed on a Sartorius LE
