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.

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.

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.).
