What is a Membrane?
A membrane is a selective barrier that allows water molecules to pass while blocking impurities. In water purification, membranes filter contaminants like salts, heavy metals, bacteria, and chemicals, making water safe for industrial and domestic use.
The effectiveness of a membrane depends on its pore size, structure, and material, making it suitable for specific purification needs.
Types of Membranes Used in Water Purification
1. Reverse Osmosis (RO) Membranes
-
Function: Removes dissolved salts, heavy metals, bacteria, and viruses.
-
Application: Widely used in industrial RO plants, domestic water purifiers, and desalination plants.
✅ Best Products on Romegamart:
2. Ultrafiltration (UF) Membranes
-
Function: Removes bacteria, viruses, and suspended solids.
-
Application: Often used as pretreatment before RO membranes.
3. Nanofiltration (NF) Membranes
-
Function: Removes hardness-causing salts, sulfates, and nitrates.
-
Application: Ideal for softening water in industries and municipal systems.
4. Microfiltration (MF) Membranes
-
Function: Removes suspended solids and larger contaminants.
-
Application: Used in the food & beverage industry and municipal treatment plants.
Advantages of Using Membranes
-
High Filtration Efficiency – Ensures pure water by removing impurities.
-
Energy Efficient – Modern membranes reduce operating costs.
