ALUMINIUM SULPHATE POWDER

500g in HDPE Bottle

Aluminium Sulphate 17% Powder Water Treatment Flocculant Clarifier 500g


📦 Product Overview

Aluminium Sulphate 17% Powder is a widely used coagulating agent designed to help clarify water by gathering fine suspended particles into larger “flocs,” making them easier to settle or filter out. This makes it suitable for process water clarification, turbidity reduction trials, filtration support, and lab or workshop demonstrations where accurate dosing is essential.

This listing is for 500g supplied by HD Chemicals LTD in a strong HDPE bottle, ideal for customers who want tougher, reusable packaging with easier pouring and resealing. HDPE packaging helps protect the powder from moisture exposure during storage and handling, reducing the chance of clumping and improving convenience for repeated dosing. When dissolved, aluminium sulphate solutions can be acidic, so handle with care, avoid dust, and always add powder to water while stirring. Store tightly closed in a cool, dry place.

  6. Strong HDPE bottle for secure storage and easy resealing

  7. Easier to pour/measure compared with bags

  8. Hygroscopic powder—closed bottle helps reduce moisture uptake

  9. Suitable for process, hobby, and lab applications

  10. Accurate metric dosing (grams/millilitres) made simple


🧼 Uses

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

  1. Jar test to find the best dose (recommended)

  • Add 1.0 L cloudy water to a jar

  • Make stock: dissolve 1.0 g in 100 mL water

  • Dose 1–10 mL (equals 0.01–0.10 g/L)

  • Stir fast 30 sec, slow 2–3 min, settle 15–30 min

  1. Routine clarification in non-potable process tanks

  • For 100 L water start with 5 g (0.05 g/L)

  • Mix 5–10 minutes, settle 30–60 minutes

  • Decant/filter clear layer; remove settled sludge

  1. Pre-filter dosing to support filtration (non-drinking)

  • Make dosing solution: 10 g in 1 L water (1%)

  • Add upstream in small steps while mixing

  • If haze occurs, reduce dose and repeat test

  1. Turbidity reduction in stored water (non-potable)

  • Dose 0.02–0.10 g/L depending on cloudiness

  • Mix well; allow extended settling

  • Clean out settled solids after treatment

  1. Color and fine particle reduction trials

  • Use jar test method

  • Increase dose by 0.02 g/L increments

  • Stop at best clarity point (avoid overdosing)

  1. Workshop/lab coagulation demonstration

  • Dose beakers at 0.01–0.05 g/L

  • Compare mixing speeds and settling performance

  • Record the best dose for repeatability

  1. Sludge thickening trials

  • Dose 0.05–0.15 g/L

  • Mix gently; allow settling

  • Measure sludge volume change and adjust

  1. Small batch maintenance dosing

  • Weigh in grams using a metric scale

  • Prepare fresh solution each session

  • Keep bottle closed between uses

  1. Clarification trials for water features (where permitted)

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

  • Monitor pH and clarity

  • Avoid sensitive systems without experience

  1. General suspended solids reduction support

  • Start low (0.02 g/L) and increase gradually

  • Mix thoroughly; allow settling

  • Keep notes for consistent dosing

❓ FAQ

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

Q2: Why HDPE bottle packaging?
A: It’s tough, resealable, easier to pour, and helps reduce moisture exposure during storage.

Q3: What’s a good starting dose?
A: For trials, start around 0.01–0.10 g/L and adjust using jar tests.

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

Q5: How do I make a dosing solution?
A: Dissolve 10 g in 1 L water (1%), then dose in millilitres.

Q6: Can it clump in storage?
A: Yes—keep the bottle tightly closed and store cool and dry to reduce clumping.

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

Q8: Is it suitable for drinking water?
A: Only if used by qualified operators under approved processes and local regulations.

Q9: What happens if I overdose?
A: It can cause haze or reduced clarity—reduce dose and re-test.

Q10: How should I store it?
A: Keep tightly closed, cool and dry; reseal immediately after each use.
