Tenten: A Key Term in Waste Management - Examining Gravity Sand Filters

The term "Tenten" in waste management refers to a specific type of gravity sand filter often utilized for effluent treatment in wastewater treatment plants. These filters play a crucial role in removing suspended solids and other contaminants from wastewater before it's discharged into the environment.

Continuously Backwashed Gravity Sand Filters

One prominent type of gravity sand filter is the continuously backwashed filter, which employs a continuous backwashing process to maintain optimal filter performance. This method involves periodically reversing the flow of water through the filter bed, effectively flushing out accumulated solids.

Leading Manufacturers

Two prominent manufacturers of continuously backwashed gravity sand filters are F.B. Leopold Company, Inc. (U.S.) and Simon-Hartley, Ltd. (U.K.). Both companies have extensive experience in the wastewater treatment industry and offer a range of filter designs tailored to specific needs.

F.B. Leopold Company, Inc.

• Features: F.B. Leopold's continuously backwashed gravity sand filters are known for their high efficiency and durability. They feature a unique design with a "Tenten" system that allows for constant backwashing, ensuring consistent performance and minimal downtime.
• Advantages: The "Tenten" system minimizes filter clogging and optimizes the backwashing process, leading to lower maintenance requirements and reduced operating costs.
• Applications: F.B. Leopold filters are commonly used in industrial wastewater treatment, municipal sewage treatment, and other applications requiring efficient solid removal.

Simon-Hartley, Ltd.

• Features: Simon-Hartley's continuously backwashed gravity sand filters are designed for high-flow applications and offer reliable operation. Their filters often incorporate a "Tenten" backwashing system for continuous cleaning.
• Advantages: Simon-Hartley filters are known for their robust construction and ability to handle high volumes of wastewater. The "Tenten" backwashing system provides continuous cleaning, ensuring high treatment efficiency.
• Applications: Simon-Hartley filters are typically used in large-scale industrial and municipal wastewater treatment plants, where high-capacity filtration is essential.

The "Tenten" System

The "Tenten" system employed by both F.B. Leopold and Simon-Hartley typically involves a series of rotating plates or paddles that distribute the backwashing water evenly across the filter bed. This ensures thorough cleaning of the sand bed and prevents channeling, leading to consistent filtration performance.

Benefits of Gravity Sand Filters with "Tenten" System

• High Filtration Efficiency: Removes suspended solids and other contaminants effectively.
• Continuous Operation: Backwashing process allows for uninterrupted operation and consistent filtration performance.
• Low Maintenance: Minimizes clogging and reduces the need for frequent cleaning and maintenance.
• Durability: Constructed from robust materials for long-term performance.
• Flexibility: Can be customized to meet specific treatment needs.

Conclusion

Gravity sand filters equipped with "Tenten" backwashing systems are essential components in wastewater treatment plants. They provide efficient and reliable solid removal, ensuring that wastewater is treated effectively before discharge. By employing continuous backwashing, these filters minimize downtime and maintenance requirements, while offering high treatment efficiency. F.B. Leopold and Simon-Hartley, with their expertise and innovative filter designs, are leading the way in providing efficient and sustainable wastewater treatment solutions.
