Before the sludge is transferred to the digester tank, it is stored in tanks. In these tanks, sludge undergoes a gravity thickening process in which solid particles settle to the bottom (dewatering process). The Rosemount 1208 Non-Contacting Level Transmitter provides non-contacting and reliable level measurement of the inside of the sludge thickening tank, helping to protect the plant against overfilling, and accurately monitoring effluent water levels and flow. The Rosemount 1208 is unaffected by environmental conditions such as condensation or temperature changes and utilizes smart algorithms to avoid false echoes from agitators.
