Amiad”s AMF2 filtration system is being used by a South Caroline WWTP to meet state effluent requirements.

Amiad Filtration Systems’ 10 micron AMF2 technology passed inspection and approval by the South Carolina Department of Health and Environmental Compliance (SCDHEC, for a package wastewater treatment plant (WWTP) located at Harbor Island near Beaufort, S.C. The system produced an effluent consisting of 0.3 PPM TSS, <2 PPM BOD, and 0.8 NTU — well within regulatory requirements.

The new filtration system features a programmable logic controller to allow the WWTP operators a full menu of monitoring and remote interface options. Capital costs, footprint size, range of filtration degree, and low O&M expenses were the main reasons Robert Gross, P.E., the plant’s owner, decided to invest in the new technology. “Amiad proved to me that the technology would provide the water quality that I needed to meet the new tertiary regulations below budget,” says Gross.

Although new to the United States, Amiad ( automatic self-cleaning filtration systems have been extensively used 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 three, seven, 10, and 20 microns, with a life expectancy of 15–20 years and operating pressure ranges between three PSI and 150 PSI.
