Sludge Depth Meter

The Markland Model 602 Sludge Depth Meter can reduce energy usage by automating sludge level detection. The meter can be used in clarifiers, tanks, inclined plate clarifiers (Lamellas), SBRs and dissolved air flotation tanks. The company offers free testing of materials at its plant, so clients will know whether the meter will work for their applications before buying it.

Significantly Reduce Sludge Production

The BAS (an acronym for “biofilm + activated sludge”) biological process was developed for wastewater streams lacking ammonia and phosphorous for biomass growth. The process reduces overall sludge production and provides a stable two-stage treatment system, a combination of a biofilm stage as a pre-treatment step, followed by an activated sludge stage. The biofilm stage is the company’s MBBR technology.

Membrane Bioreactors

PURON submerged modules are the latest in MBR technology anduse a single header design with hollow fibers fixed only at the bottom. The fibers have an internal braid providing mechanical strength, and are sealed at the top, making them less susceptible to clogging. The systems offer low energy use, stable filtration and low chemical consumption.
