ALUMINIUM SULPHATE POWDER

500g in Alubag

Aluminium Sulphate 17% Powder Water Treatment Flocculant Clarifier 500g

📦 Product Overview

Aluminium Sulphate 17% Powder is a proven coagulating agent used to clarify water by binding fine suspended particles into larger “flocs” that settle faster or filter out more efficiently. It’s commonly used for process water clarification, filtration support, turbidity reduction trials, and lab or workshop testing where repeatable dosing is important.

This 500g size is ideal for users who need more product for routine treatments, multiple jar tests, or ongoing clarification work while still keeping storage simple. Supplied by HD Chemicals LTD in a heat-sealed aluminium bag to help protect against moisture (the powder is hygroscopic and may clump if exposed to humidity). When dissolved, the solution can be acidic, so handle carefully, dose gradually, and always add powder to water while stirring. Store sealed, cool, and dry.

  8. Suitable for process, hobby, and lab applications

  9. Allows accurate metric dosing (grams/millilitres)

  10. Heat-sealed aluminium bag for cleaner storage and handling

🧼 Uses

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

  1. Jar test for best dose (recommended first step)

  • Add 1.0 L cloudy water to a jar

  • Make stock: 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. Filtration performance boost (pre-filter dosing)

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

  • Add upstream in small steps while mixing

  • Monitor clarity and filter loading; reduce if haze appears

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

  • Dose 0.02–0.10 g/L depending on cloudiness

  • Mix well and allow extended settling

  • Clean out settled solids after treatment

  1. Color and fine particle trial removal

  • Use jar test method

  • Increase dose in 0.02 g/L increments

  • Stop at best clarity point (avoid overdosing)

  1. Workshop/lab coagulation demonstrations

  • Dose beakers at 0.01–0.05 g/L

  • Compare mixing speeds and settling times

  • Record results for repeatable dosing

  1. Sludge thickening and settling trials

  • Dose 0.05–0.15 g/L

  • Mix gently, allow settling

  • Measure sludge volume change and adjust dose

  1. Multi-batch maintenance dosing

  • Weigh doses in grams using a metric scale

  • Prepare fresh solution for each session

  • Label containers clearly and keep sealed

  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 removal support

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

  • Mix thoroughly, then let settle

  • Keep notes for consistent repeat performance

❓ 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 should I do a jar test first?
A: Water chemistry varies—jar testing helps find the best dose and avoids overdosing.

Q3: What’s a typical starting dose?
A: Often 0.01–0.10 g/L in trials, adjusted based on clarity results.

Q4: Will it change pH?
A: Yes—solutions are usually acidic and can lower pH.

Q5: How do I make a dosing solution?
A: A simple option is 10 g in 1 L water (1%). Dose in millilitres.

Q6: Why is the bag heat sealed?
A: To reduce moisture uptake—this powder can clump if exposed to humidity.

Q7: What PPE is recommended?
A: Gloves and eye protection minimum; avoid inhaling dust; wash after use.

Q8: Can I use it for drinking water?
A: Only if you’re qualified and following approved processes and local regulations.

Q9: What if I overdose?
A: Clarity can worsen or haze can form—reduce the dose and re-test.

Q10: How should I store it?
A: Keep sealed, cool, and dry; reseal tightly after opening to prevent clumping.
