Water Treatment and Filtration with Expanded Clay Aggregates Eca

High-performance ceramsite (high-strength ceramsite) refers to calcined or non-burning ceramsite with high strength, low water absorption and low density. Can be used to formulate high performance concrete. It is generally called high-performance light aggregate in foreign countries, and it can also be called high-strength ceramsite in China

The Benefits of Using ECA Pebbles As A Biofilter & Water Filtration Media

Now that you understand the basics of light expanded clay aggregate and how it's made, let's discuss the benefits it has compared to other filtration media like sand, carbon, and other common wastewater filtration media. Here are just a few reasons it's widely considered to be the best filter media for water treatment.

• Unparalleled longevity - ECA is made of clay, which will never degrade or deteriorate. You don't have to worry about periodic sand replacement to keep your filter media clean and fully functional. ECA pebbles require minimal maintenance and last a long time.
   
• Easy to backwash - If your facility needs to backwash to clean your filter media, ECA is a great choice as a sand replacement. The tiny air pockets in the pebbles mean that water and compressed air can be used to easily clean away contaminants and maintain the filter media, making it one of the best filter media options for facilities using backwashing.
   
• Extremely high surface area - ECA is a good sand replacement because it has a similarly high surface area. The tiny bubbles and air pockets throughout the filter media mean that the surface area is similar to sand, carbon, and other popular types of filtration media.
   
• Dual-action filtration - ECA can be used as a sand replacement to catch and filter both physical and biological contaminants in waste water treatment plants. This simplifies the process of setting up and maintaining the filtration media since ECA can be used for both parts of the filtration process.
   
• Excellent drainage - The porous structure of ECA allows it to provide fast, excellent drainage while still maintaining great filtration properties. This makes it a superior sand replacement, especially in high-volume applications where water may take a very long time to filter through traditional sand beds.
