Sludge dewatering is one way of preparing wastewater sludge for proper disposal. Sludge is the byproduct of wastewater cleansing. This has created a long-standing problem for companies in the wastewater treatment industry. Fortunately, dewatering has created a way to reduce the volume of sludge by removing water. The result is a lightweight, relatively dry cake that can be easily disposed of.
What Is Dewatering?
Sludge is a semi-solid substance that is produced when treating wastewater from industrial and municipal processes. The dewatering process turns this material into a solid cake by removing the excess water. It is a fiercely regulated area of wastewater treatment. This is because sludge disposal techniques must meet strict standards to minimize potential damage to the environment.
Why Is Dewatering Beneficial?
Because the process of dewatering removes liquids, the result is an item with a lower volume. This can greatly reduce the cost of transporting and disposing of sludge. After all, lower volumes mean less weight to transport and dispose of. It can also reduce extra costs, such as sludge storage. This is especially true for companies that have effective dewatering methods. The drier cakes are, the cheaper they will be to transport and dispose of. They will also pose less of a threat to the environment since they will be less likely to leak from a truck. Furthermore, the dewatering process is not labor-intensive, so companies tend to save money by using it.
Another benefit of dewatering is wastewater recycling. This means that once the excess water is removed from sludge, it is reused by the company. While it may not be usable for drinking, it can still be used for other applications. For instance, it can be burned in steam-powered plants.
Dewatering is a cost-effective way of disposing of sludge. This is because the process removes excess water and lowers the volume of a company’s wastewater byproducts.
