Introduction

The dual media technology is used in various water treatment plants. Mainly because of its effective construction and dual filtration procedure. Water in a dual media filters passes through media with moderately smaller pores. Anthracite exudes out the largest molecules. Next layer removes particles with the help of adhesion and straining combination feature of sand and garnet. Filters do not block as fast as they do in a single filtration process. It is basically due to multiple depth or filters in dual media filter process.

Different Types of Dual Media Filters

1. Calcite Filters- Calcite is a compound that is naturally found in the environment. Therefore, it is cost effective. Calcite filters help to enhance the pH levels in water. They also neutralize water. Straining of pipes can be avoided because of this.

2. Anthracite Filter- This filter is used with sand in dual media filters. It’s gravity is lighter than sand and this feature makes it more suitable. Moreover, it can resist more chemicals as it has high carbon content. It is considered as one of the best options to remove suspended solid and turbidity. In bio=film treatment, anthracite is used as a carrier. It also helps in the growth of micro-flocks.

3. Activated Charcoal Filters- Charcoal, in other words carbon, is treated with oxygen. Small pores are open between the carbon atoms resulting in absorption of impurities from liquid and gases. Organic matters, chlorine, and disinfectants are removed from water with the help of activated charcoal filters. They are also known to enhance the taste of water. Using this process before any other filtration process such as reverse osmosis, saves oxidation.

Features of Dual Media Filters

  • Simple design
