Embodiment 1-4

[0144] Four material samples detailed in Table 1, including polished Type 316 stainless steel (Comparative Example 1), low density polyethylene (LDPE, Example 2), linear low density polyethylene (LLDPE, Example 3) and polychlorinated Vinyl (PVC, Example 4), attached to ramps with adjustable inclination angles.

[0145] A 55 gallon plexiglass tank was constructed and the inclined plate settler of Examples 1-4 was placed in it. The inclination of the flakes relative to the ground varies between 40° and 65°. Influent from the Allegheny River is treated chemically enough to cause flocculation and directed to inclined plate settlers.
