Coagulation & flocculation
Ferrous Chloride
Ferrous chloride
A ferrous salt option for specified reduction, sulfide-control and water treatment steps.
Confirmed availableBase chemicals
- Chemical identity
- Ferrous chloride (FeCl₂) family; confirm tetrahydrate crystals and industrial aqueous solutions separately by supplied form.
- Product form
- Selected solution or solid format.
Add application & specification details
Application value
Uses and application conditions
Coagulation, flocculation & clarification; Sulfide & odor control
Use these checks to compare equivalent supply specifications and narrow the candidate range for your actual process.
Specification & document coordination
Align specification basis, test methods and grade-specific documents.
Packaging & supply coordination
Review quantity, packaging and destination requirements.
Specifications & selection
Specifications and order requirements
Discuss your current grade or operating conditions. ENVO codes identify sales requirements; manufacturer grades, supply specifications, test methods and document versions are confirmed for the selected product.
Application-specific specificationBase chemicals
Availability confirmed. Share the intended use, preferred form and key requirements to confirm the grade and its technical documentation.
Application conditions & technical scope
Assess separately from ferric coagulation. Consider chloride load, pH, oxidation and downstream separation.
Appearance and supplied form
Confirm the form before comparing specifications.
Check the required form, then compare the composition, specifications and test conditions of the specific grade.
Product forms to compare
Tetrahydrate crystals/lumps; industrial solution listed separately
Tetrahydrate yellow-green to pale green; yellow-brown surface oxidation possible
Appearance information supports initial screening only. Color cannot establish chemical identity, concentration or quality grade. Confirm the actual batch using supply documents and samples.

Application issues and troubleshooting
Ferrous Chloride — troubleshooting checks
Review symptoms, possible causes and verification steps together to prepare a more focused product-selection discussion.
01Fine suspended solids or scum remain after Ferrous Chloride dosing
- Possible causes
- Changes in water charge, pH/alkalinity, oil/dye type or mixing and separation conditions may make the existing specification unsuitable.
- Investigation and resolution
- Distinguish colloid coagulation, demulsification and flocculation first. Compare the coagulant and supporting PAM using the same water sample, assessing clarification and separation.
- Checks required
- Provide ferrous content; free acid; impurities; downstream solid–liquid separation, plus current product, actual water sample and process location.
- Application limits
- The coagulant name alone cannot establish removal of an oil phase, metal complexes or dissolved COD.
02Sludge or pH changes from Ferrous Chloride differ from expectations
- Possible causes
- The active-component basis, acid/alkali demand or jointly used chemicals may have changed; inorganic salts and organic polymers act differently.
- Investigation and resolution
- Use the same active-metal or polymer basis. Record pH, sludge and downstream dewatering, assessing the main chemical and aid separately.
- Checks required
- Incoming-water pH and alkalinity, current chemical documents, process sequence, sludge samples and equipment records.
- Application limits
- Candidate chemicals are not a blend that must all be used together; confirm reaction locations and product compatibility separately.
03Color changes in ferrous chloride tetrahydrate or solution
- Possible causes
- Oxidation, acidity or hydration changes can produce yellow-green to yellow-brown appearance differences.
- Investigation and resolution
- Compare Fe(II)/total iron and free acid; confirm tetrahydrate solid versus industrial solution.
- Checks required
- Actual form, product SDS, test methods, storage and sampling times.
- Application limits
- Green crystal images cannot represent all industrial ferrous chloride solutions; color does not establish reducing capacity.

More questions, answered.
Fine suspended solids or scum remain after Ferrous Chloride dosing — what should I check?
Distinguish colloid coagulation, demulsification and flocculation first. Compare the coagulant and supporting PAM using the same water sample, assessing clarification and separation.
What should I compare when buying Ferrous Chloride?
Share the application, current product, purchase quantity and delivery location to help confirm a suitable specification. Key checks include: Ferrous iron content; Free acid; Impurities; Downstream solid–liquid separation. Compare the current grade document and the same test basis before choosing an alternative.
Which documents should accompany a Ferrous Chloride enquiry?
Request the current grade-specific TDS and product SDS, the COA for the actual supplied batch, and any intended-use documents required for the destination. Share the application, specification, quantity and delivery requirements. Document version, batch coverage and public-release scope are confirmed for the specific request.
