Content, basicity and density are matched to the selected liquid model. Confirm the pH test method and any additional industrial impurity limits. “Not specified” does not mean zero.
Specify the liquid model and delivery basis.
1. Choose industrial or drinking-water grade first. Confirm the model’s Al₂O₃ content, basicity and density together.
2. Provide your water analysis, treatment stage and target, then establish the proposed model and dosage through a jar test.
3. Confirm the pH test method, any additional impurity requirements and net product weight. A 1,000 L IBC capacity is not a net-weight specification.
Match the grade to the water-treatment duty.
Industrial liquid models can be reviewed for industrial wastewater and process-water treatment. Drinking-water liquid models have a separate specification for drinking-water supply and relevant process-water applications. The selected grade and documents must match the intended use.
Packaging & storage
1,000 L IBCs. Confirm net product weight, number of IBCs, loading arrangement and destination for the selected model.
Store liquid in a cool place, protected from freezing and direct sunlight; confirm shelf life for the selected model.
Sample availability, quantity and buyer-paid international courier charges are agreed before dispatch.
Model documents
Request documents for the selected model and test conditions. A representative COA supports evaluation; the supplied lot’s COA records its tested results.
