Description:

Integrity verification testing of the ADI International Inc. Pilot Test Unit No. 2002-09 with MEDIA G2® arsenic adsorption media filter system was conducted at the Hilltown Township Water and Sewer Authority (HTWSA) Well Station No. 1 in Sellersville, Pennsylvania from October 8 through October 21, 2003. The source water was groundwater from Well No. 1, one of three HTWSA's groundwater supply wells. The water was disinfected with sodium hypochlorite prior to being withdrawn from the well site's chlorine detention tank. Verification testing was conducted at the operating conditions specified by the manufacturer. The feed water, with an average total arsenic concentration of 21mg/L and a pH of approximately 7.4, was treated with sulfuric acid prior to entering the treatment unit. When operated under the manufacturer's specified conditions at this site, at the design flow rate of 1.7 gpm, the ADI International Inc. Pilot Test Unit No. 2002-09 with MEDIA G2® system reduced feed water arsenic from the average 21 mg/L to an average of 7 mg/L in the treated water during the Integrity Test.
