Digester Biogas Flow Measurement
Digester Biogas Flow Measurement

The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system.

MRI Water Treatment Package Systems MRI Water Treatment Package Systems

Backed by more than 35 years of design and manufacturing experience, MRI’s Packaged Water Treatment Systems combine into a single tank the reliable, all-stainless steel, space-saving components proven through years of use in large municipal treatment systems.

MRI Flocculation Systems™ MRI Flocculation Systems™

With increasingly stringent regulations and adoption of membrane filtration, the pressure is on for all stages of pretreatment — chemical feed, flocculation, sedimentation, and filtration — to act in concert. In response, Meurer Research, Inc. has developed MRI Flocculation Systems™ — integrating turbine, horizontal, and hydraulic flocculators into multi-stage systems with a self-cleaning hydraulic final stage, maximizing versatility and performance.

MRI Hoseless Cable-Vac™ Sludge Collector MRI Hoseless Cable-Vac™ Sludge Collector

Developed in 2002, the MRI Hoseless Cable-Vac Sludge Collector removes settled solids throughout the basin, even from the final 2′ at the end wall typically left un-collected by other sludge collectors.

Lamella EcoFlow® Inclined Plate Settler Lamella EcoFlow® Inclined Plate Settler

The Lamella® is the original inclined plate gravity settler. Introduced by Parkson in 1971, it has been the industry standard for this technology.

Membrane Aerated Biofilm Reactors (MABR) Membrane Aerated Biofilm Reactors (MABR)

This revolutionary aerobic wastewater treatment solution is modular and reduces energy usage by up to 90% compared to conventional treatment.

SCOUT Hydro Profiling System SCOUT Hydro Profiling System

The Reliant Water Technologies SCOUT Hydro Profiling System is the answer to obtaining clear and concise shallow water survey data quickly and inexpensively. By not only providing a visual hydrographic ‘picture’ of everything underwater, in any shallow body of water, the SCOUT also provides the volume of sludge in the water body (as well as the volume of free water). The ‘picture’ provided is color enhanced in order to provide clear, definitive delineation of variable depths of sludge, or debris, and includes multi-point water depth over-lays.

AquaPrime™: Cloth Media Filter AquaPrime™: Cloth Media Filter

The AquaPrime system utilizes a disk configuration and the exclusive OptiFiber® cloth filtration media to effectively filter screened, de-gritted, raw municipal sewage. This proven technology easily handles significantly higher solids loading rates compared to secondary clarified effluent (by a factor of 3 to 5 times) with the added ability to sustain a low TSS concentration, making it an ideal solution for both wet weather treatment and primary treatment in lieu of conventional sedimentation systems.

IFT Sludge Thickener IFT Sludge Thickener

The IFT Rotary Drum Sludge Thickener offers best in class performance for achieving 5-15% solids for municipal wastewater sludge. JWC’s Rotary Drum Thickener almost exclusively utilizes woven wire mesh screening panels for the construction of the drum. This allows for capture rates in excess of 98% and a much lower polymer use compared to systems using perforated plates or wedgewire drums.  The wire mesh screening media is built into removable panels that are installed on a drum frame.  This allows for a simple exchange of screening panels if they are damaged or conditions change without having to acquire a full drum.

Heliantis™ Solar Sludge Drying Heliantis™ Solar Sludge Drying

Heliantis™ transforms any type of dewatered sludge (15% minimum dry content) into a dry, granulated product with a dry-solids content that can be adjusted within a range of 35% to 85%. Using the sun as the main energy source, the sludge is dried in a greenhouse and a scarifying machine turns over and breaks up the sludge into carbon-neutral and odorless granules, for eventual agricultural reuse or thermal energy production using co-incineration.
