Techniques

MiniBUS: A Powerful Tool for Environmental & Water Treatment

This document will explore the MiniBUS system in detail, covering its techniques, models, software, best practices, and case studies.

Chapter 1: Techniques

1.1 Ultrafiltration: The Core Technology

The MiniBUS system primarily relies on ultrafiltration (UF), a membrane-based separation process. UF membranes possess pores in the range of 0.01 to 0.1 microns, effectively separating suspended solids, bacteria, viruses, and other contaminants from the water. The driving force for this separation is pressure, which forces the water through the membrane while retaining the larger particles.
