Sensors - Markland Specialty Engineering Automatic Sludge Blanket Level Detector

The Automatic Sludge Blanket Level Detector from Markland Specialty Engineering controls solid-liquid interface levels and automates biosolids removal. Used in primary, secondary and backwash clarifiers and settlement tanks (including lamellas, dissolved air flotation units and decanting tanks), its use of LEDs enables it to locate both the settled silt or biosolids bed and overlying cloud layer, automatically adjusting beam intensity to accommodate different concentrations. Its slim profile is ideal for obstructed/constricted areas. It allows users to program pumps to operate only when necessary, helping prevent carryover, optimize feed density for enhanced dewatering and avoid pumping thin biosolids or large volumes of water (as when a core hold is pulled). These efficiencies help reduce energy use, wear and tear on pumps and downtime for maintenance. No calibration is required. 855-873-7791;
