The 10-µm AMF2 new filtration system provides high effluent quality and incorporates a state-of-the-art programmable logic controller, allowing wastewater treatment plant operators a full menu of monitoring and remote-interface options. This automatic self-cleaning system has been used extensively for the last 12 years throughout Europe and Canada for water treatment and removal of Cryptosporidium. The design of the filtration elements consists of a series of thread-wound cassettes fastened into a carousel assembly that forms a cleaning element. Currently available filtration degrees are 3, 7, 10, and 20 μm. Systems have a life expectancy of 15 to 20 years. Operating pressure ranges between 3 and 150 lb/in.2.

Videographic Data Recorder
The SM500F is a four-channel, field-mountable videographic data recorder that can take recording and monitoring out of the control room. It offers users localized access to operational data wherever the process may be and can be installed easily into a panel, wall, or pipe. Its fully sealed NEMA 4X and IP66 enclosure provides full protection against water, dirt, and dust, making it suitable for hose-down and dirty applications in the field and at the process.
