Chemically Assisted Sedimentation or Clarification. In this process, chemicals are added to water, and through mixing, the suspended solids, and other impurities are stuck together and form floc, settling at the bottom of the basin. Generally, the most used process is chemically assisted as horizontal sedimentation based on some assumptions.

There are two ways to break down the pulp used to make paper: mechanically and chemically. When it is broken down mechanically, the resulting pulp is known as "groundwood pulp". This process does not require chemicals, but the lignin is not removed. This results in a relatively high yield of pulp, but the paper does turn yellow as it ages.
