What is filtration in water treatment?

Filtration in water treatment refers specifically to the process of removing suspended particles, impurities, and some microorganisms from water by passing it through porous materials or filter media. These materials can include sand, gravel, membranes, or other substances designed to trap contaminants while allowing clean water to flow through. This method is critical for improving water clarity and quality, as it effectively reduces turbidity and eliminates various particles that might adversely affect water safety and taste.

The effectiveness of filtration depends on the characteristics of both the filter medium and the nature of the impurities present in the water. Different filtration techniques can be employed based on the specific requirements and contamination levels of the water being treated. This process is fundamental in many water treatment systems, ensuring access to potable water that meets health and safety standards.
