Microfine: A Key Term in Water Treatment and the USFilter/Memcor Ultrafiltration System

This document will explore the concept of microfine filtration and the USFilter/Memcor Ultrafiltration system, diving into the techniques, models, software, best practices, and case studies associated with this advanced water treatment technology.

Chapter 1: Techniques

Microfine Filtration Techniques

Microfine filtration involves removing particles in the size range of 0.1 to 10 microns, employing a variety of techniques:

• Membrane Filtration: This is the most common method, utilizing semi-permeable membranes with precisely controlled pore sizes. Ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) are all membrane filtration techniques that operate within the microfine range.
• Depth Filtration: This method uses a porous medium with a complex structure to trap particles, achieving microfine filtration by accumulating them within the filter material.
• Coagulation and Flocculation: These techniques are often used as a pre-treatment step before microfine filtration. They involve adding chemicals to agglomerate smaller particles into larger, more easily filterable flocs.
• Electrostatic Precipitation: This technique utilizes charged electrodes to attract and remove particles based on their charge. It's particularly effective for smaller particles within the microfine range.

USFilter/Memcor Ultrafiltration System

The USFilter/Memcor Ultrafiltration System primarily relies on membrane filtration. The system uses hollow fiber membranes, characterized by their high surface area and efficient filtration capabilities. These membranes are designed to remove a wide range of contaminants within the microfine range, including:

• Suspended solids: Silt, clay, and other particulate matter
• Bacteria and viruses: Pathogens that can cause disease
• Organic matter: Natural organic compounds and synthetic materials
• Colloids: Tiny particles that remain suspended in solution

Chapter 2: Models

Ultrafiltration Membrane Models

USFilter/Memcor offers a variety of ultrafiltration membrane models, each tailored to specific applications and contaminant removal requirements. These models are categorized based on:

• Membrane material: Polyethersulfone (PES), polyvinylidene fluoride (PVDF), and other materials are chosen for their specific properties and resistance to contaminants.
• Pore size: The pore size of the membrane determines the filtration cut-off point, defining the minimum size of particles that can be removed.
• Module configuration: Hollow fiber, flat sheet, and spiral wound modules are designed for different flow rates and pressure requirements.

Example Models

• Memcor MP Series: This series includes a range of hollow fiber membranes with different pore sizes, ideal for municipal and industrial water treatment.
• Memcor FP Series: Flat sheet membranes in this series offer a high surface area, suited for applications requiring large flow rates and high filtration capacity.
