Coagulant and Flocculant Brief: Feed, Sequence and Separator
TL;DR Start a coagulant or flocculant enquiry with the feed, the treatment step and the receiving separator. Distinguish a reaction or charge-control problem from a separation problem, then compare a proposed sequence on representative feed. The brief connects the process question to actual PAC, aluminium-salt, organic coagulant and PAM routes.

Compare the actual Coagulants & Flocculants catalog when the required product identity is known. This checklist organizes a purchasing brief; use the related technical guide below for the application-specific investigation.
Build a comparable specification
| Decision | Compare | Why it matters |
|---|---|---|
| Remaining problem | Dissolved/reactive material, colloids, emulsified oil or suspended solids; actual required outlet | Separates the treatment task from a generic request for a stronger chemical. |
| Feed baseline | Source and sampling history, pH/alkalinity, salts, solids and relevant contaminants | Defines the matrix that a representative comparison must preserve. |
| Chemical sequence | Preparation, existing additions, rapid mixing, flocculation shear and residence | Identifies whether a process correction or a new candidate should be tested first. |
| Receiving separator | Settling, DAF, filtration or dewatering; liquid quality, captured solids and handling | Connects the comparison to the real equipment rather than clear supernatant alone. |
Connect the sample to the operating decision
Follow the symptom through collection, preparation, mixing and separation before changing the chemical. Use the current program as the reference, control one change and retain both the liquid and solids observations. A feed-and-sequence brief organizes the process investigation; the detailed jar-test guide addresses trial acceptance, while the delivered-cost guide below compares quotations and cost at the measured treatment endpoint.
Compare delivered quotations and treatment cost after the feed, candidate identity and separation endpoint are defined.

Send the brief for an offer
Include the product or unresolved task, agreed specification, quantity and unit, packaging, destination and required documents. If a candidate has been tested, retain the exact sample/grade identity and preparation record so the offer can be compared with what was evaluated.

Frequently asked questions
Why should the separator be named in a chemical enquiry?
A candidate that settles well in a jar may behave differently in flotation, filtration or mechanical dewatering. Naming the real separator lets the trial compare liquid quality, captured solids and equipment response under relevant conditions.
Which documents belong with a purchase specification?
A current TDS describes the offered grade, an SDS addresses its hazards and handling, and a batch COA records reported measurements for that lot. Confirm version, grade and the applicable analytical basis; company management-system certificates have a separate scope.
What should I include in the initial enquiry?
Send the chemical name or product code, required specification and document needs, quantity and unit, packaging, destination and the intended application. Add a representative sample or trial reference when it is available.
