ALUMINIUM SULPHATE POWDER

250g in Alubag

🛒 Product Title: 

Aluminium Sulphate 17% Powder Water Treatment Flocculant Clarifier 250g

📦 Product Overview

Aluminium Sulphate 17% Powder is a reliable coagulating agent used to help clarify water by binding fine suspended particles into heavier “flocs” that settle faster or filter out more easily. This makes it useful for controlled water-cleaning trials, process water clarification, hobby filtration projects, and lab demonstrations where accurate dosing matters. The 250g size is ideal for small-batch work, jar tests, and routine maintenance tasks without handling large volumes.

Supplied by HD Chemicals LTD in a heat-sealed aluminium bag to help protect the powder from moisture (it can absorb water from the air and clump if left open). When dissolved, solutions can be acidic, so careful handling is essential. Always add powder to water while stirring, measure accurately using a metric scale, and store sealed in a cool, dry place.

🧼 Uses

Safety first: Wear gloves and eye protection. Avoid breathing dust. Use in a ventilated area. Solutions may be acidic—handle carefully. Always follow local rules for treatment and disposal.

  1. Jar test for water clarification (trial dosing)

  • Fill a jar with 1.0 L cloudy water

  • Make a stock solution: dissolve 1.0 g in 100 mL water

  • Add 1–10 mL of stock (equals 0.01–0.10 g/L)

  • Stir fast 30 sec, then slow 2–3 min

  • Leave 15–30 min to settle, then compare clarity

  1. Small batch process water settling (non-potable)

  • For 10 L water, start with 0.5 g (0.05 g/L)

  • Mix 2–5 minutes, rest 20–40 minutes

  • Decant clearer water or filter

  1. DIY pre-filter support (non-drinking applications)

  • Dissolve 5 g in 1 L water (dosing solution)

  • Add slowly before a filter while mixing

  • Stop if overdosing causes haze; reduce dose and re-test

  1. Suspended solids reduction in storage tanks (non-potable)

  • Dose 0.02–0.10 g/L depending on turbidity

  • Mix thoroughly, allow longer settling (30–60 min)

  • Remove settled sludge from the bottom

  1. Lab/classroom coagulation demonstration

  • Use beakers with 0.01–0.05 g/L

  • Compare different doses and mixing speeds

  • Record settling times and clarity changes

  1. Color/turbidity trial improvement (process water)

  • Use jar test steps

  • Increase dose by 0.02 g/L increments

  • Identify best clarity point without overdosing

  1. Filtration efficiency testing

  • Run untreated vs treated water through the same filter

  • Dose around 0.03–0.08 g/L

  • Compare filter loading and water clarity

  1. Sludge thickening trial

  • Dose 0.05–0.15 g/L, mix gently

  • Allow settling, measure sludge volume reduction

  • Adjust dose based on results

  1. Small pond/water feature clarification trials (where permitted)

  • Always test on 10–20 L first at 0.02–0.05 g/L

  • Monitor pH and clarity

  • Avoid treating sensitive systems without expertise

  1. General coagulation aid for fine particulate removal

  • Start low (0.02 g/L)

  • Increase gradually until clear improvement is observed

  • Keep notes for repeatable dosing

❓ FAQ

Q1: What does “17%” mean?
A: It’s a common strength marking used in industry for aluminium sulphate products (often tied to aluminium oxide equivalent in specifications).

Q2: Is this the same as “alum”?
A: It’s often called filter alum/papermaker’s alum, but “alum” can also mean other salts—check your required chemical name.

Q3: How do I start dosing safely?
A: Use a jar test first at 0.01–0.10 g/L to find the best dose for your water.

Q4: Does it affect pH?
A: Yes, it can lower pH because solutions are typically acidic.

Q5: How do I make a simple dosing solution?
A: Dissolve 10 g in 1 L water (1% solution). Add measured millilitres to your test water.

Q6: Why is it in a heat-sealed aluminium bag?
A: To reduce moisture exposure—this powder can absorb water from the air and clump.

Q7: What PPE should I use?
A: Gloves and eye protection minimum; avoid inhaling dust; wash hands after handling.

Q8: Can I use it in drinking water systems?
A: Only if you are qualified and compliant with local regulations and approved processes.

Q9: What happens if I overdose?
A: Overdosing can reduce clarity or create haze—reduce the dose and re-test.

Q10: How should I store it after opening?
A: Reseal tightly and store cool and dry to prevent clumping and moisture uptake.
