Anionic - an ion or a group of ions having a negative charge that characteristically moves toward positively charged ions.

Aqueous - An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations as a subscript (aq).

Cationic - An ion or group of ions having a positive charge that characteristically move toward the negatively charged ions.

Flocculation - A polymer carries either a positive or negative charge and thereby attracts a large number of sediment particles with the opposite charge thereby creating larger and heavier particles causing the heavier particle to settle out at a faster rate.

This is a process where a solute comes out of solution in the form of floc or "flakes". The term is also used to refer to the process by which fine particulates are caused to clump together into floc.  Depending on it's weight, the floc may then float to the top of the liquid, or settle to the bottom of the liquid.

Polymers - A substance containing many molecules that have been purposely joined together to perform a specific function. These molecules form a chain-like structure and can be either a crystal or linear in composition.

Polyacrylamide - "Polyacrylamide" and "PAM" are generic terms. PAMs are polymers made up of many repeating subunits (monomers). As with all polymers, the properties of PAMs are very dependant on the size and weight of the polymer. PAMs also vary in molecular size, depending on the number of acrylamide monomers (AMD) that are combined to form the polyacrylamide chain.

TMDL - A TMDL or Total Maximum Daily Load is a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards, and an allocation of that amount to the pollutants sources.

A TMDL is the sum of the allowable loads of a single pollutant from all contributing point and non-point sources. The calculation must include a margin of safety to ensure that the water body can be used for the purposes the State has designated. The calculation must also account for seasonable variation in water quality.
