Sludge Controls

  Wastewater treatment plants need to manage sludge well. If they don't, it costs more money, and the plant might not run right. Knowing where the sludge sits in your tanks is key. You need a fast, simple way to check the sludge blanket level. Why is Sludge Level Important? Sludge is the solid part left over after cleaning the water. It settles at the bottom of clarifiers or thickeners. This layer is called the sludge blanket. If the blanket gets too high, solids can flow over the top. That means the water leaving the plant isn't clean enough. If the blanket gets too low, you might pump out too much water with the sludge. This makes the next step—dewatering—much harder. Keeping the sludge blanket at the right height saves time and money. It also helps the plant meet strict environmental rules. How to Check the Level Many plants use a fixed sensor in their tanks. These sensors work well, but they can be expensive to install and only check one spot. Sometimes, you nee...
