Aerobic wastewater treatment on a Carribean island
SBR technology
In 2011, at the request of a beverage producer, a wastewater treatment plant was planned, built and commissioned on a Caribbean island. Full biological treatment of the wastewater was required in order to be able to discharge the effluent directly into the receiving water. A key challenge in industrial wastewater treatment is dealing with high fluctuations in wastewater volume and the substances it contains - as was the case in this project.
NUMBERS & FACTS:
• Location: A Carribean island
• Hydraulic capacity: 450 m³/d
• Organic load: 2000 mg/l (BOD)
• Year of construction: 2011
CONCEPTUAL FORMULATION
Flexible wastewater treatment methods have proven particularly suitable for such tasks. The biological treatment stage forms the center of the treatment plant. The SBR technology (Sequencing Batch Reactor) is often used for this kind of task. This technology is also able to clean complex, highly organically polluted production wastewater in cost-effective and reliable way.
For tasks of this kind, CUSS has developed processing concepts that take into consideration the project-specific conditions that ensure the reliable operation of the plant also in cases of extremely high peak flows. These processes have been used in many cases and been optimized for a variety of conditions.
The CUSS process engineers have been using this and other methods for more than 30 years. Based on the accumulated experience of all employees, the used methods are constantly optimized and enhanced. Through this, the company CUSS is always able to provide its clients with safe and state-of-the-art technology.
