Drinking Water Sterilisation (Potable Water Treatment) ⚠️ CRITICAL: Never add granules directly to drinking water Step 1: Pre-filter Water (if needed) If water is cloudy, filter through cloth or sediment filter Suspended solids reduce chlorine effectiveness Step 2: Prepare Stock Chlorine Solution Weigh 1 gram calcium hypochlorite Add to 1 litre clean water in a clean container Add water first, then chemical (prevents reaction risk) Stir for at least 15 minutes until fully dissolved Step 3: Dose Drinking Water Add 0.1 ml (≈2 drops) of solution per 1 litre water For 10 litres → 1 ml For 100 litres → 10 ml Step 4: Contact Time Leave for minimum 30 minutes Target residual chlorine: 0.2 – 0.5 mg/L Step 5: Verification Water should have slight chlorine smell If not → repeat half dose and wait 15 minutes Step 6: Storage After Treatment Keep treated water covered Use within 24 hours for best quality Safety: Do not overdose Never mix with acids (toxic gas risk) Harmful if swallowed in concentrated form 2. Swimming Pool Shock Treatment Step 1: Test Water Ideal pH: 7.0 – 7.4 Ensure filtration system operational Step 2: Calculate Dose Typical shock dose: 10–15 g per m³ (1,000 litres) Example: 10,000 L pool → 100–150 g Step 3: Pre-dissolve Dissolve granules in bucket of water (5–10 litres) Stir until dissolved Step 4: Apply to Pool Add evenly around pool perimeter Do NOT add when swimmers present Step 5: Circulation Run pump for 8–12 hours Step 6: Re-test Before Use Chlorine should drop below 3 mg/L before swimming Safety: Never mix with other pool chemicals Add chemical to water, not water to chemical 3. Routine Pool Chlorination (Maintenance) Step 1: Daily Dose Calculation Typical: 500 g – 1 kg per 100 m³ per day Step 2: Adjust for Conditions Increase during: Hot weather Heavy pool usage Step 3: Application Dose via skimmer (if suitable) or pre-dissolve Add gradually with pump running Step 4: Monitor Levels Maintain: Free chlorine: 1–3 mg/L Step 5: Balance Water Chemistry Total alkalinity: 60–120 mg/L 4. Spa / Hot Tub Treatment Step 1: Measure Water Volume Example: 1,000 litres spa Step 2: Dose Add 2–5 grams per 1,000 litres Step 3: Pre-dissolve Dissolve in 1–2 litres water Step 4: Add with Jets Running Ensures even distribution Step 5: Contact Time Wait 15–30 minutes Step 6: Test Before Use Safe chlorine: 3–5 mg/L for spa Safety: Keep cover open briefly after dosing Avoid inhaling vapours 5. Surface & Equipment Disinfection Step 1: Pre-clean Surface Remove dirt and organic matter Step 2: Prepare Disinfection Solution Dissolve 1–2 grams in 1 litre water Creates approx. 500–1000 ppm chlorine solution Step 3: Apply Solution Use cloth, spray, or immersion Step 4: Contact Time Leave for 5–10 minutes Step 5: Rinse (if required) Especially for food-contact surfaces Step 6: Air Dry Safety: Use gloves and eye protection Use in ventilated area 📈 Other Names Alternative Names: Calcium Hypochlorite 68%, Cal Hypo Granules, Chlorine Granules, Drinking Water Chlorine, Pool Shock, Water Purification Chlorine Keyword-Rich Titles: Calcium Hypochlorite Drinking Water Treatment Chlorine Granules 68% for Pools & Potable Water Cal Hypo Granules Emergency Water Purification Pool Shock & Water Sterilisation Chlorine Granules Unstabilised Chlorine Granules High Strength ❓ FAQs 1.
