Dystor: A Key Component in Anaerobic Digestion - Understanding USFilter/Envirex's Gas Holder System
Anaerobic digestion, a biological process that breaks down organic matter in the absence of oxygen, plays a crucial role in wastewater treatment and renewable energy production. The process generates biogas, a valuable energy source, and digestate, a nutrient-rich fertilizer. However, efficient anaerobic digestion relies on carefully controlled environmental conditions, including pressure and gas management. This is where "Dystor" comes into play.
What is Dystor?
Dystor is a term frequently used in the context of environmental and water treatment, particularly in relation to anaerobic digestion. It refers to a gas holder system, specifically designed to manage the biogas produced during this process. These systems play a critical role in ensuring efficient and reliable operation of anaerobic digesters.
USFilter/Envirex's Gas Holder System
USFilter/Envirex, a leading provider of water and wastewater treatment solutions, has developed a sophisticated gas holder system designed for anaerobic digestion. This system, commonly referred to as the "Dystor," incorporates several key features:
- Flexible membrane: The Dystor utilizes a flexible membrane, typically made of a durable material like PVC or polyester, to contain the biogas. The membrane expands and contracts as the biogas pressure fluctuates, ensuring consistent pressure regulation.

- Gas collection and transfer: The Dystor system includes a collection system to capture the biogas and a transfer system to direct the gas to its intended application, such as fuel for engines or energy production.
- Pressure regulation: The system incorporates pressure regulation mechanisms to ensure the biogas pressure remains within safe and efficient operating parameters.
Benefits of the USFilter/Envirex Dystor System:
- Efficient gas management: The flexible membrane and floating cover effectively manage the biogas produced during digestion, ensuring optimal pressure control.
- Improved digester performance: By maintaining stable environmental conditions within the digester, the system optimizes digestion efficiency, leading to higher biogas yield and reduced digester downtime.
