Hawk has introduced an interface level system using a sonar transducer for level control. The Orca Sonar system is designed for improved sensing of interface levels in clarifiers and thickeners. The new sensors offer improvements in overall power, penetration, and calibration density range. They perform under high suspended solids loading, “sliming” and generally upset process conditions.

Kruger, a Veolia Water Solutions & Technologies company, has enhanced the effectiveness of solar sludge drying by coupling two well-known processes: air drying and aerobic fermentation. Its automated SOLIAMIX™ windrow turner aerates the biosolids and promotes fermentation which produces heat to aid the drying process. Biosolids windrow utilization maximizes the drying surface area. The SOLIA™ process produces an end product that reduces the amount of biosolids, minimizing disposal costs.

The Model 675 submersible level transmitter from AMETEK PMT Products is designed specifically for slurries and highly viscous environments where clogging of the sensor is possible. It uses a 3.5" flush diaphragm within a stainless steel shark cage to prevent unwanted clogging of the sensor area. The instrument is made of 316L stainless steel, is able to perform in depths up to 138 feet of water and is approved for intrinsically safe operation in hazardous locations, including lift stations, sewage level measurement, slurries, storm runoffs and pump control.

Dewatering system

Eimco Water Technologies’ CINETIK™ Linear Electro-Dewatering system dewaters and reduces pathogen levels in sludge, using less energy and less space than other systems. Installed in a WWTP after existing mechanical dewatering equipment, the system allows for high dryness levels (30-50% TS), even for secondary and mixed biological sludge. The technology is based on the combined action of controlled mechanical pressure and electro-osmosis, where a continuous current is applied to electrodes, liberating and carrying away the water bonded to hydrophilic particles.

The Super Shredder® in-line disintegrator from Franklin Miller reduces tough solids directly in sludge or raw sewage lines. Its design provides a high level of open area to fluid flow making the unit ideal for applications requiring a heavy duty size reduction processor that can handle high flows with minimal headloss. The system features a patented “spherical shredding” mechanism that cuts and shears sewage solids into fine bits.

The LWT Electric Pit Hog™ dredge provides efficient removal of settled solids without shutting down your processes. Fitted with an electric remote controlled solids handling pump, the dredge pulls biosolids material as standard to 14 foot depths at upwards of 900 gpm or more. It can be fitted with a VFD to closely match dewatering or other processes. Options include Auto Sense (Auto Stop), Bottom Sense (Bottom Contour Sensing) or a PLC Controlled Automated System for computerized dredge solids density control. If the sludge is to be dewatered with belt presses, centrifuges or geo-textile tubes, to name a few, LWT can supply a dredge specifically for the job at a level of automated control that fits project specifications.

The Moyno® 2000 HS System includes key features, such as a twin-screw feeder, that enable it to handle semi-dry, high solids content material. The twin screw feeder includes two self-cleaning, intermeshing feed screws that supply a constant, pressurized feed rate to the system’s Moyno® G4 Progressing Cavity Pump. The resulting 100% pump cavity fill rate enhances overall system performance and cost efficiency.
