Application value
Uses and application conditions
Coagulation, flocculation & clarification
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 specificationSpecialty formulations
Availability confirmed. Share the intended use, preferred form and key requirements to confirm the grade and its technical documentation.
Application conditions & technical scope
Select against composition, assay basis and end-use documents. ACH grades and parameters are not directly equivalent to PAC.
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
Liquid water-treatment ACH; solid listed separately
Current ENVO grade color pending documentation
Appearance information supports initial screening only. Color cannot establish chemical identity, concentration or quality grade. Confirm the actual batch using supply documents and samples.
Appearance and technical references
These public sources help check product categories, possible appearances and general application limits. They do not replace the TDS, SDS or batch COA for a specific ENVO grade.

Application issues and troubleshooting
Aluminium Chlorohydrate — 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 Aluminium Chlorohydrate 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 Al₂O₃ basis; basicity; impurities; intended use, 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 Aluminium Chlorohydrate 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.
03Equal-mass ACH/PAC substitution changes treatment and pH behavior
- Possible causes
- Composition, active-aluminum basis and basicity may differ between these aluminum coagulants.
- Investigation and resolution
- Align active-aluminum measurement basis; assess pH, clarification and downstream filtration with the same raw water.
- Checks required
- Current product's active aluminum and basicity, raw-water pH/alkalinity, target water use and trial records.
- Application limits
- ACH and PAC are not equivalent specifications interchangeable at equal commercial mass; confirm end-use grade and supply form separately.

More questions, answered.
Fine suspended solids or scum remain after Aluminium Chlorohydrate 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 Aluminium Chlorohydrate?
Share the application, current product, purchase quantity and delivery location to help confirm a suitable specification. Key checks include: Al₂O₃ basis; Basicity; Impurities; Specific end use. Compare the current grade document and the same test basis before choosing an alternative.
Which documents should accompany a Aluminium Chlorohydrate 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.
