Channel disintegrator

The Dimminutor® Turbo model provides automatic screening and grinding of wastewater solids in straight-through channels and wet wells. The unit is designed to reduce solids to fine particles, enhancing plant operation and improving the reliability of pumps and other downstream equipment. The system employs a smooth, continuously rotating design with high torque. As its three bidirectional rotary cutters intermesh at close clearance with stationary cutters, solids are reduced to a size small enough to pass through an ultraprecision sizing screen. With no gaps or openings between the screen and cutters, output is controlled. System features include faster sweeping and cleaning, an open design to handle high flow rates with low head loss, easy maintenance, individually replaceable cutters, elimination of seals or bearings near the gritty channel floor, and design for precision and long life.

Converter box

The C-Con™ Converter box is designed to convert most simplex and duplex control panels to utilize the floatless technology of the C-Level™ sensor. The box converts the signal from the C-Level™ sensor to simulate float levels (up to four floats). Activation levels can be set and adjusted at the box using the output dials, eliminating the need to go into the tank to move float tether points. The simulate button enables testing for proper wiring of outputs. The converter box features an enclosure for indoor use and can be mounted inside a control panel. With a 3-year limited warranty, the system is designed to operate in wastewater pump tanks, confined-space applications, and systems with high grease content. The converter also can be used as an alternative to mercury float switches.

Pressure transducer

PXM309 Metric series transducers are designed to have static accuracy of 0.25% and 1% total error band over a compensated range of –20°C to 85°C. Featuring stainless steel construction and solid state reliability, the transducers are suited for most industrial applications as well as engine test stands. A thin film of oil transfers the pressure and is designed to ensure high accuracy and stability of the sensor. The transducers are sealed to an IP65 environmental rating. They are available with three electrical terminations, a 2-m cable with flying leads, and a mini-DIN connector or a four-pin M12 connector. Omega Engineering (Stamford, Conn.).

It is designed to provide accuracy and precision with automated features to improve productivity and ease of use and maintenance, without external reagents or gas supplies. GE (Fairfield, Conn.).


Modular enclosure

The Hammond Modular Enclosure (HME) Series is a versatile housing for industrial controls, operator interface equipment, and switches and circuit breakers. The enclosure is constructed with a fully welded frame for strength and rigidity. The series’ three designs include the HME single door version, the HMET double door units, and the HFMD (single-door) and HFMDT (double-door) flanged disconnect versions, which are sized to accept disconnect switches from all leading manufacturers. The enclosure frame profile features square cage nut and round holes at 25-mm centers for mounting equipment and accessories, reinforced eyebolts for easy lifting, and a base gland plate with adjustable opening for cable entry.

Membrane system

The AquaMB Process® multiple barrier membrane system uses batch biological treatment with cloth media filtration and external ultra-filtration membranes to provide enhanced biological nutrient removal and virus and bacteria removal for reuse applications. The system is designed to offer low life-cycle cost, flexible cycle structures for enhanced bio-nutrient removal without additional tanks, automated in-place cleaning of membranes for minimal operator attention, less membrane area and chemical use to reduce costs, and easy adaptability to changing influent characteristics and effluent objectives. The system allows integration of the IntelliPro® process monitoring and control system to optimize plant performance. Aqua Aerobic Systems Inc. (Rockford, Ill.).


Tertiary filter

FlowTex is a tertiary filter for treatment plants that have stringent suspended solids discharge permit requirements or that require reuse-quality effluent. As flow passes through the cloth media discs, suspended solids are removed. Accumulated solids are removed during backwashing by rotating a vacuum head across the surface of the disc. The design allows filtered effluent from each disc segment to be sent through individual discharge ports. The independently operated segments can be replaced without taking the entire filter off-line. Entex Technologies Inc. (Chapel Hill, N.C.).


Non-batching process unit

The Duperon® Washer Compactor is a non-batching process unit that is designed to efficiently clean and compact screenings of less than 4 in. at rates of up to 60 ft3/h. The system features a dual-auger system that uses thermal-mechanical dynamics to enable absorption of grease into the debris’ naturally occurring fibrous materials. The unit’s discharge chute, which travels up to 10 ft, is designed to fit any site. The system is designed to result in compacted debris volume reduction of 84% and dry solids reduction of 60%.
