Techniques
Chapter 1: Techniques
Oxidation: The Heart of Oxigritter
The Oxigritter system utilizes dissolved oxygen as a key element in its operation. This dissolved oxygen is introduced into the aeration tank, where it reacts with the organic matter present in the wastewater. This process, known as oxidation, leads to a breakdown of soluble organic matter, effectively reducing the Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) of the wastewater.
How Oxidation Works:
- Aerobic bacteria: The dissolved oxygen creates a favorable environment for aerobic bacteria to thrive. These bacteria utilize the oxygen to break down organic matter, converting it into simpler, less harmful substances.
- Oxidation reactions: The process involves complex chemical reactions where organic matter is oxidized, leading to the release of energy and the formation of simpler molecules like carbon dioxide and water.
Grit Removal: Ensuring Downstream Efficiency
The Oxigritter system includes an efficient grit removal system that plays a crucial role in the overall treatment process.
Why Grit Removal is Essential:
- Clogging: Grit, mainly composed of sand, gravel, and other heavy particles, can clog pipes and equipment in downstream treatment processes.
- Damage: These particles can damage pumps and other equipment, leading to costly repairs and downtime.
- Treatment inefficiency: The presence of grit can interfere with the effectiveness of other treatment processes, such as sedimentation and filtration.
Grit Removal in Oxigritter:
The Oxigritter system uses various techniques for effective grit removal:
- Gravity settling: Heavy grit particles settle at the bottom of the tank due to their density.
- Velocity control: The water flow is carefully controlled to ensure that grit settles effectively while lighter organic matter remains in suspension.
- Grit collection: A dedicated system collects the settled grit for disposal or further treatment.
Benefits of Effective Grit Removal:
- Reduced maintenance: Less clogging means fewer repairs and less downtime for treatment plants.
- Improved efficiency: The uninterrupted flow of wastewater ensures optimal performance of downstream processes.
- Extended equipment lifespan: Protected equipment lasts longer, reducing replacement costs.
