Viva Blu PAC 10% – Professional Water Clarifier & Coagulant

• Municipal Water Treatment: Use 5-15 mg/L depending on raw water turbidity (measured in NTU). For moderately turbid water (50-100 NTU), start with 10 mg/L and adjust based on jar test results for optimal floc formation.
• Industrial Wastewater: Apply 20-50 mg/L for high-organic or heavy-metal-laden water. Pre-mix with a small volume of water for even distribution and monitor the settling time (typically 30-60 minutes).
• Swimming Pools: Dose at 2-5 mg/L to eliminate cloudiness and enhance chlorine efficiency. Add directly to the skimmer or dilute in a bucket of water, then circulate for 4-6 hours.
• General Use Tips: Always conduct a jar test to determine the exact dosage for your specific water conditions. Store in a cool, dry place and use within 12 months for peak potency.

• Paper and pulp industry: Pitch and ink particle removal; retention aid in paper manufacturing
• Mining and minerals processing: Tailings water clarification and process water recycling in Australian mining operations
• Irrigation water treatment: Turbidity reduction in agricultural irrigation channels and dam water
• Cooling tower and industrial water systems: Control of suspended solids in recirculating cooling water systems
• Sludge dewatering aid: Conditioning of biosolids and sludge prior to belt press or centrifuge dewatering
• Potable water treatment in remote/regional communities: Packaged plant coagulation where alum may cause excessive pH depression

Dosing Rates & Guidelines

All dosing rates are indicative and should be confirmed by jar testing for the specific water matrix. Site conditions including raw water turbidity, alkalinity, pH, temperature, and organic load will significantly influence optimal dose. Rates below are expressed as PAC 10% product volume unless otherwise stated.

Note on unit conversion: PAC 10% product at 1.20 g/mL density: 1 mg/L as Al₂O₃ ≈ 8.3 mL/m³ of PAC 10% product. Always confirm the Al₂O₃ content of the specific batch via Certificate of Analysis before calculating dose.

Dilution Instructions

PAC 10% is supplied as a ready-to-use liquid coagulant. Dilution prior to dosing is recommended for small-volume applications, low-flow systems, or where precise metering equipment is not available. Always dilute PAC into water — never add water to neat PAC in a concentrated stream, as localised heating and splashing may occur.

• Equipment required: Chemical-resistant polyethylene (HDPE or LDPE) mixing container or drum, HDPE or polypropylene measuring vessels, calibrated dosing pump (peristaltic or diaphragm type), appropriate PPE (see Safety & Handling section)
• Compatible dilution water: Clean potable water or treated process water at ambient temperature (5–35°C). Do not use hard bore water with alkalinity >300 mg/L as CaCO₃ without testing, as premature hydrolysis may occur.

1. Don full PPE before handling: chemical splash goggles, face shield, nitrile gloves (minimum 0.3 mm thickness), chemical-resistant apron, and closed-toe footwear.
2. Add the required volume of clean water to the mixing container first — fill to approximately 80% of the final volume.
3. Slowly pour or pump the measured volume of PAC 10% into the water while stirring gently. Never reverse this order.
4. For a working dilution of 1:10 (v/v): add 1 part PAC 10% to 9 parts water. This produces an approximately 1% Al₂O₃ solution suitable for pool and small-volume applications.
5. For a working dilution of 1:100 (v/v): add 1 part PAC 10% to 99 parts water. Suitable for precise low-dose applications via manual dosing.
6. Top up the container to final volume with water and mix gently for 2–3 minutes. Do not use high-shear mechanical mixers — excessive agitation can pre-flocculate the product.
7. Label the diluted container clearly with product name, concentration, date of preparation, and hazard pictograms (Class 8 Corrosive).
8. Use diluted PAC solutions within 24 hours of preparation. Diluted product is less stable than the neat liquid and may lose coagulant efficacy over time, particularly above 30°C.
9. Rinse all mixing equipment thoroughly with clean water after use.

Continuous dosing systems: PAC 10% may be dosed neat via chemical metering pumps fitted with HDPE or PVC wetted parts. Teflon (PTFE) pump heads and tubing are preferred for long-term service. Calibrate dosing pump output weekly. Install an injection point with back-pressure valve to prevent siphoning.

Chemical Compatibility

Compatible With

• Water — fully miscible; compatible with potable, process, and wastewater
• Anionic polyacrylamide flocculants — synergistic; PAC should be dosed upstream of polymer addition with sufficient mixing time (30–60 seconds) between the two dose points
• Chlorine (sodium hypochlorite, calcium hypochlorite) — compatible at typical treatment concentrations; dose PAC and chlorine at separate injection points
• Carbon dioxide (CO₂) — compatible; CO₂ may be used for pH adjustment in conjunction with PAC in drinking water applications
• Activated carbon (powdered or granular) — compatible; dose PAC first, allow initial floc formation, then add carbon
• Sand, anthracite, and multimedia filtration media — PAC-treated water is suitable for all standard granular media filters
• HDPE, LDPE, PVC, PP, PTFE, fibreglass-reinforced plastic (FRP) — all suitable for storage vessels, piping, and dosing equipment
• 316 stainless steel — acceptable for short-term contact; 304 SS not recommended for extended service

Incompatible With — Do NOT Mix

• Cationic polymers (cationic polyacrylamide, polydadmac): Direct mixing causes immediate charge neutralisation and precipitation, rendering both products ineffective. If both are required, dose at separate injection points with at least 2–3 pipe diameters of separation.
• Strong alkaline solutions (sodium hydroxide, lime, soda ash at high concentration): Causes rapid precipitation of aluminium hydroxide Al(OH)₃ as a gelatinous mass, blocking lines and wasting chemical. If pH adjustment is required, dose PAC first and adjust pH downstream after initial floc formation.
• Concentrated mineral acids (sulphuric acid, hydrochloric acid): Generates heat and may release aluminium chloride fumes. Do not store or handle in the same area without adequate segregation.
• Oxidising agents in high concentration (hydrogen peroxide >10%, potassium permanganate, chlorine dioxide): Potential for exothermic reaction and degradation of the PAC polymer structure at contact points.
