Chapter 1: Techniques

Membrane Technology: The Heart of Aquasource

Aquasource systems rely on the principle of membrane filtration, a process that separates contaminants from water based on their size and charge. The heart of the system is a semi-permeable membrane, which acts as a barrier, allowing clean water to pass through while retaining contaminants.

Types of Membranes Used in Aquasource Systems:

• Microfiltration (MF): MF membranes have larger pore sizes, typically in the range of 0.1 to 10 microns. They are effective at removing suspended solids, bacteria, and algae.
• Ultrafiltration (UF): UF membranes have smaller pore sizes, typically in the range of 0.01 to 0.1 microns. They can remove smaller particles like viruses, colloids, and some dissolved organic matter.
• Nanofiltration (NF): NF membranes have pore sizes in the nanometer range, typically around 1 to 10 nanometers. They are capable of removing dissolved organic compounds, pesticides, and heavy metals.
• Reverse Osmosis (RO): RO membranes have the smallest pore sizes, often in the range of 0.1 to 1 nanometers. They are the most advanced membrane technology and can remove even dissolved salts, minerals, and viruses.

Advantages of Membrane Filtration in Aquasource Systems:

• High-quality water production: Membranes effectively remove a wide range of contaminants, resulting in clean and safe water.
• Reduced chemical usage: Membrane systems typically require less chemical treatment compared to traditional methods, minimizing environmental impact and operational costs.
