Techniques

Chapter 1: Techniques

Pressure-Driven Membrane Filtration: The Heart of HPD

HPD technology centers around pressure-driven membrane filtration, a process that leverages the force of pressure to drive water through a semi-permeable membrane. This membrane acts as a barrier, selectively allowing water molecules to pass through while rejecting contaminants. The key principle lies in the difference in permeability between the membrane and the contaminants, allowing for efficient separation.

Here are the primary techniques employed in HPD systems:

• Microfiltration (MF): This technique uses membranes with pore sizes ranging from 0.1 to 10 micrometers, effectively removing suspended solids, bacteria, and other larger particles.
• Ultrafiltration (UF): With pore sizes in the range of 0.01 to 0.1 micrometers, UF targets smaller contaminants like viruses, colloids, and macromolecules.
• Nanofiltration (NF): NF membranes possess even smaller pore sizes (1 to 10 nanometers) and can remove dissolved organic matter, heavy metals, and other dissolved contaminants.
• Reverse Osmosis (RO): This technique utilizes membranes with the smallest pore sizes (less than 1 nanometer), capable of removing dissolved salts, minerals, and even viruses and bacteria.

The choice of technique depends on the specific water quality requirements and the contaminants to be removed. HPD offers a range of membrane types, tailored to various applications and challenges.
