Filter Media & Components
Overview
The performance of any water treatment system depends heavily on the quality of filter media and internal components used. Green Nature Solutions supplies a comprehensive range of filter media, ion exchange resins, membranes and system components sourced from trusted manufacturers, ensuring consistent and reliable filtration performance.
Filter Media
| Media | Application |
|---|---|
| Activated Carbon | Removal of chlorine, colour, odour and dissolved organics |
| MnO₂ (Manganese Dioxide) | Iron and manganese removal |
| Anthracite | Top layer in dual/multi-media filters for coarse filtration |
| Green Sand | Iron, manganese and hydrogen sulphide removal |
| Birm Media | Catalytic iron and manganese removal (pH dependent) |
| Quartz Sand | Primary filtration media in sand filters |
| Pebbles | Support bed beneath filter media |
Birm Media – pH Requirements:
- Iron removal only: Feed water pH > 6.8
- Iron + Manganese: pH between 7.5 and 8.5
- Manganese removal only: pH between 8.0 and 9.0
Ion Exchange Resins
| Resin Type | Application |
|---|---|
| Cation Resin (Strong Acid) | Softening, DM plants — removes Ca²⁺, Mg²⁺, Na⁺ |
| Anion Resin (Strong Base) | DM plants — removes sulphates, chlorides, silica |
| Mixed Bed Resin | Ultra-pure water production (combined cation + anion) |
Membranes
| Type | Application |
|---|---|
| BW RO Membranes | Brackish water reverse osmosis |
| SW RO Membranes | Seawater reverse osmosis |
| NF Membranes | Nanofiltration for partial demineralisation |
| UF Membranes | Ultrafiltration for suspended solids and colloid removal |
System Components
- PP Strainers – Polypropylene inline strainers for pre-filtration
- Ejectors – For chemical dosing and backwash air scour
- Membrane Connectors – Inter-element connectors for membrane pressure vessels
- Brine Seals – Prevent feed water bypass around membrane elements
- Membrane Pressure Tubes – SS304 / SS316 tubes for housing RO/NF/UF elements
