MARKLAND SPECIALTY ENGINEERING

---

 Since 1967, Markland Specialty Engineering has been designing and manufacturing process monitoring and control instrumentation that is valued by operators, managers and consultants, in diverse sectors, around the globe.

 Markland’s Automatic Sludge Blanket Level Detector is used wherever liquids are separated from solids. With its sensors automatically adjusting to accommodate thick or thin concentrations, the detector tracks the liquid-solids interface level as it rises and falls. By entering two independent set-points (high and low), operators program underflow pumps to operate only when necessary to maintain preferred sludge levels, helping to prevent process upsets such as septic sludge conditions and carryover, and to maximize water removal. 

 Markland’s simple and effective single point monitoring and automatic control to maintain your preferred sludge blanket and supernatant interface level. 

 With The Sludge Gun® handheld, portable sludge blanket level detector, easily measure & monitor liquid-solids interface levels in septic tanks, ponds, lagoons and clarifiers. Its sensor, with thumbwheel sensitivity control, detects thick or thin silt, sludge or biosolids blankets, even light flocs. Compact & weatherproof, it helps eliminate unnecessary pumping or dredging, facilitate routine monitoring for regulatory compliance and prevent carryover. Ideal for use from catwalks and boats. 

 Suspended Solids Density Meters are ultrasonic sludge & slurry density meters. Inline TSS analyzer or throw-in TSS probe sensors monitor total suspended solids and provide continuous readings. They excel in challenging applications such as thick concentrations and small pipes. Ultrasonic sensors are inherently safe – no permits, no approvals needed. 

 The Duckbill™ Automatic Composite Wastewater Sampler for influent, effluent & sewage is the explosion-proof & self-cleaning wastewater sampling equipment that uses compressed air to move samples (no pump, no vacuum system), even up high lifts & over long runs. It can sample multiple sites simultaneously, even in remote locations and cold climates. A stand-out in municipal & industrial wastewater applications, installations for this Simpler Sampler™ include tanks, non-pressurized pipes, sewers, lift stations, sumps, pits and more.
