Among its most recognized innovations are the Automatic composite sampler and its high-precision sludge and solids detection tools, which are helping municipal and industrial facilities worldwide achieve regulatory compliance and optimized process performance.

Maintaining precise control over water and wastewater systems requires reliable, high-quality data. Markland’s Automatic Composite Sampling System, known as the Duckbill, provides a robust, self-cleaning solution for collecting representative samples from tanks, sewers, and lift stations. By using compressed air rather than mechanical pumps or vacuum systems, this system is inherently explosion-proof and capable of moving samples over extreme vertical lifts and long horizontal distances, ensuring reliable operation even in the most challenging and remote environments.

Precision Instrumentation for Accurate Solids Management

In addition to its advanced sampling technology, Markland addresses the critical need for monitoring sludge density and interface levels. While the company offers fixed-point density meters for continuous process control, its Portable tss meter and sludge level detection equipment—most notably the Sludge Gun—remain essential tools for operators.

The Sludge Gun is a world-renowned portable instrument that allows operators to quickly and accurately determine sludge blanket levels. By providing an audible signal when it detects the liquid-solids interface, this rugged, battery-powered tool enables operators to perform routine checks from catwalks, boats, or lagoons. It eliminates guesswork in sludge blanket detection, helping facilities prevent carryover and avoid unnecessary dredging or pumping, which ultimately results in significant energy and maintenance savings.

Why Facilities Rely on Markland Specialty Engineering

Markland Specialty Engineering continues to serve a global client base by focusing on simplicity, durability, and factory-direct support. Their instrumentation is designed to withstand harsh industrial conditions while providing the accuracy required for modern wastewater treatment, mining, petrochemical, and food processing applications.

Systems like the Duckbill sampler feature virtually no moving parts, ensuring long-term performance with minimal maintenance. Equipment is customizable to suit unique site requirements, including different materials for corrosive environments and flexible programming for flow-proportional or time-based sampling. By automating sludge removal and optimizing chemical dosing through accurate solids measurement, facilities can reduce operational expenses and improve the quality of outflow for reuse. Every piece of equipment is backed by the company's extensive experience, providing customers with direct access to design and technical support.
