Water Treatment Information

Find clear, South African-ready guidance on filtration, disinfection and water quality management. This hub brings together step-by-step installation guides, practical tips, and sizing calculators to help you select, install and maintain the right solution — from cartridges and UV sterilisation to RO systems, pH correction and iron/manganese removal. We’ll keep expanding this section as new requests come in and fresh content is published.

What you’ll find
✓ Practical “how-to” articles written in plain language
✓ Installation guides with photos/diagrams and metric measurements
✓ Troubleshooting checklists for common issues
✓ Sizing tools and calculators for quick, accurate selections
✓ Brand-specific notes, compatible parts and maintenance intervals

Popular topics
• Sediment filtration & micron selection (1–100 µm; Slimline & Big Blue)
• Carbon filtration (GAC vs Carbon Block) for taste, odour and chlorine/chloramine
• KDF & advanced cartridges for heavy metals and hydrogen sulphide
• Iron & manganese removal media (e.g., Katalox Light, DMI-65) and pre-oxidation basics
• pH correction (Calcite, Aquastab) and corrosion control (Siliphos)
• UV sterilisation principles, sleeve cleaning and lamp replacement
• Reverse Osmosis: pre-treatment, production rates, tank sizing and remineralisation
• LSI & hardness: scaling vs corrosion, balancing and real-world examples
• Turbidity control, filter staging and pressure-drop management
• Whole-house vs point-of-use: choosing the right scope

Guides & checklists
✓ 3-Stage Big Blue with UV — layout, by-pass plumbing and commissioning
✓ Under-counter RO — cartridge order, membrane handling and flush procedure
✓ Cartridge maintenance — changeout intervals by water quality and usage
✓ Media systems — vessel loading, backwash rates and start-up steps
✓ UV systems — flow limits, dose guidance and safety notes

Tools & calculators
• Flow-rate converter (L/min ↔ L/h)
• UV sizing helper (by target L/h)
• RO production estimator (GPD ↔ L/h with temperature factor)
• Langelier Saturation Index (LSI) calculator
• Media/backwash rate estimator (by vessel size)
• Cartridge lifespan estimator (by influent quality & demand)

Troubleshooting
✓ Low pressure after install — staging, micron choice and blocked cartridges
✓ RO low output or taste carry-over — pre-filters, membrane and flush routine
✓ UV alarms or low dose — quartz sleeve fouling and flow conformity
✓ Metallic taste/colour — oxidation, media choice and contact time
✓ Scale or corrosion evidence — LSI balance, pH correction and Siliphos dosing

Good to know
• Always size from a recent water analysis where available.
• Observe NSF/WQA guidance where specified by the product.
• Keep spares on hand (cartridges, O-rings, UV lamps/sleeves) for uninterrupted service.
