Jar testing is the fastest way to understand whether a PAM grade will create dense floc, clear overflow, and a manageable sludge blanket.
Start with water from the real process
Use site water whenever possible. Salinity, pH, oil, clay, and biological solids can all change polymer behavior. A clean-water test may show hydration quality, but it will not prove field performance.
Screen the PAM family first
For mineral solids, include anionic polyacrylamide. For organic sludge or biological solids, include cationic polyacrylamide. If chemistry is uncertain, also test a nonionic polyacrylamide candidate.
Watch for overdosing
The clearest jar at the highest dose is not automatically the best choice. Overdosing can create fragile floc, slimy sludge, or carryover when the plant mixing conditions change.
