Sand Dollar

Sand Dollars and Sludge: A Winning Combination for Wastewater Treatment

The term "sand dollar" might conjure images of beachcombing and seaside vacations. However, in the world of environmental and water treatment, it holds a different significance, representing a crucial component in sludge drying bed systems. These beds, often utilized in wastewater treatment plants, rely on natural processes like evaporation and gravity to remove excess moisture from sewage sludge, a byproduct of wastewater treatment.

One company leading the way in designing and manufacturing equipment for these systems is Cherrington Corporation. Their expertise lies in providing sludge harvesting machines specifically designed for sand dollar beds.

Sand Dollar Beds: A Sustainable Approach

Sand dollar beds are unique because they utilize a layer of sand, often mixed with a small percentage of gravel, to facilitate sludge drying. The "sand dollars" themselves are strategically positioned within the bed, serving as evaporation channels. This carefully engineered design allows for efficient drying, maximizing surface area and promoting airflow.
