Why LECA Is The Best Water Filtration Media For Waste Water Treatment
Many different types of media are used in wastewater treatment, including sand, carbon, and even materials like nutshells and shredded rubber tires. But if you’re looking for a cost-effective way to filter water and to encourage the removal of ammonia via nitrification, LECA (light expanded clay aggregate) is an excellent choice for filtration media. Let’s take a deeper look at LECA pellets now, and explain why they’re so useful for water filtration and wastewater treatment.
What Is LECA And How Does It Help With Waste Water Treatment?
Wondering what light expanded clay aggregate is, and how it helps with water treatment, removal of ammonia, nitrification, and other steps in the water filtration process? Let’s discuss the basics of LECA pebbles and how they’re made.
LECA (light expanded clay aggregate) pebbles are made from clay using special rotary kilns that heat up to 1200°C. When they spin and expand, thousands of tiny air bubbles form inside the clay as it expands and creates round or oval LECA pebbles.
Light expanded clay aggregate gets its name from the fact that it’s extremely lightweight compared to its size, due to the presence of gas bubbles within the clay. LECA is used as an aggregate for concrete, but also is useful as a water filtration media. Let’s explore its benefits in wastewater treatment and water filtration now, and discuss why it’s the best filter media for use as a biofilter and in wastewater treatment.
The Benefits of Using LECA 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.
Choose The Best Biological Filter Media – Light Expanded Clay Aggregate
For all of the above reasons, light expanded clay aggregate is an excellent sand replacement for your current filter media at water treatment facilities. It’s long-lasting, durable, and can be cleaned easily for long-term use with backwash techniques. Not only that, but it filters both physical and biological contaminants.
The high surface area means that LECA pebbles are one of the best biological filter media available for water treatment. So don’t wait. Continue to explore the opportunities offered by this novel filter media, and learn more about using light expanded clay aggregate as the best filter media at your treatment facility.
