Sludge dewatering is the process of separating sludge into liquid and solid components. It is often done with sewage sludge, although sludge that is produced through industrial processes can also be dewatered. In any case, the purpose of sludge dewatering is to make waste disposal easier. It isn’t intended to treat the liquid and solid components to make it potable in any way, although some solid sewage sludge can be used in fertilizers and “biosolid compost.”
Why Sludge Dewatering is Important
The best reason to dewater sludge is to make it easier and cheaper to dispose of the resulting waste. It can also help with a company’s sustainability objectives. Sludge dewatering typically reduces the weight of sludge that needs to be disposed of, although it doesn’t reduce the amount. Less weight means that it is easier to transport in smaller and more efficient vehicles. Removing the water from solid sludge also helps to reduce its volume so it is easier to haul and store if need be. There’s also the fact that some sewage sludge can be used as fertilizer, which helps the agriculture industry if potentially harmful materials are properly filtered out of the sludge. It is vitally important that anyone who uses fertilizer made from sewage sludge make sure that the product is safe to use on their crops.
The techniques used to dewater sludge can vary greatly depending on the nature of the sludge and how much needs to be dewatered. Naturally, different companies provide different dewatering and waste disposal services, so it is always best to shop around and find the beset sludge dewatering service for your own business. With the right service, you can make it easier to dispose of your waste in ways that will help the environment as well as your own budget.
