Yes, it is, Sludge storage tanks typically require covers to keep them at the proper temperature: often 90°F for mesophilic operation, or 140°F for thermophilic operation. It can be difficult to develop a cover that’s lightweight, yet offers proper insulation for a sludge storage tank, whether you work in the waste management or livestock rearing industry.
Expanded Clay Aggregate (ECA) is ideal for this purpose. ECA can be used to create a floating cover layer on sludge tanks. It’s very lightweight and has highly thermally-insulative properties. In turn, this helps ensure the proper operation of the microbes and micro-organisms in your tank, streamlining the waste management process and enhancing efficiency.
