The Spiralift SLD screens, washes, transports and compacts channel-borne wastewater solids. The system, available from Franklin Miller, can be installed in existing channels and is an alternative to complex fine screens. In the SLD, a duplex Taskmaster® Titan™ grinder finely reduces all incoming solids. Next, the Spiralift screen captures, conditions and conveys solids out of the channel while leaving essential organic materials in the flow. The SLD employs an oversized 14" diameter screen basket constructed of stainless steel for extended life and improved washing.

Sigma Controls has introduced its microprocessor based Model 9000PT Tank Level Transmitter/ Remote Telemetry Unit, offering accuracy of 0.1% and a large LCD display of tank level. The unit offers both analog (4/20mA) and digital (MVNET, MODBUS) outputs for remote level monitoring and pump control. These digital outputs can be transmitted via modem or spread spectrum (license free) radios to a Sigma Myriad Pump Controller. The Myriad Pump Controller receiving the level signals will operate and manage up to four (4) constant speed or variable speed pumps to maintain an accurate tank water level, and the controller's graphical LCD display and 5 key operator interface to permit full user configuration of pump functionality and alarm monitoring. In addition, the company's Infilink remote monitoring software can be used to view and change settings on the controller from any PC-equipped remote location.
