Sensors Measure Sludge Concentrations too Thick for Optical Methods

Markland Specialty Engineering offers a meter that monitors process slurries and wastewater sludge densities. The meter works by sending data to a computer or control system, where users adjust fluid or particulate amounts and polymer/chemical dosing to obtain preferred concentrations.

Operators can program sludge-removal pumps for optimum density for feeding to digesters, belt presses and centrifuges. Changes in filtrate density may indicate breaks in filtration material. The sensor is non-intrusive and can also measure concentrations too thick for optical methods. It uses non-radioactive ultrasound. Readings are not affected by color of particulates/fluid. Markland offers engineering reports of the meter’s response to customers’ materials at no-charge.
