The traditional septic tanks are just a way to keep wastewater from ending in the environment: you have a container made of concrete, steel, plastic, or fiberglass that you have to empty regularly to avoid waste going directly to the landfill. Consequently, there’s no way to eliminate the sludge other than regular removal after the chemical reactions occur. Typically, septic tanks would accumulate the organic waste from domestic activities (primarily grey and black water), but they weren’t designed to support recycling or biogas production. Bio Septic Tank – What Are The Differences? What’s different about bio septic tanks, and why sometimes a traditional septic tank isn’t the right choice? Let’s take a closer look.
This organic, nutrient-rich sludge can be used in the planting and growing process. In a bio septic tank, the process will generate biogas, usable water, and sometimes bio-fertilizer.
It all happens thanks to an artificial process that mimics a natural phenomenon: the tank provides an environment where bacteria can digest organic waste and transform it into renewable energy. In the last years, the system has been improved to permit biogas production and water recycling. Historically, septic tanks have been used for collecting and sometimes filtering wastewater in households that aren’t connected to the grid. This sealed environment creates the ideal conditions for a series of chemical reactions, enabling the fermentation process to result in methane, carbon dioxide, and water. In biogas production, this chamber is also called a digester. A bio septic tank is a waterproof chamber where bacteria break down organic waste from wastewater without oxygen through anaerobic digestion.
