These commercial thin film BWRO elements are wrapped in a hard shell of FRP for added strength and to withstand higher pressure drops. High-flow option for higher permeate production are available in select sizes. (High-flow models are indicated by “AHF” at the end of the part number.)

AMI reverse osmosis membrane elements are among the finest in the industry. With hundreds of thousands of RO membranes in operation world-wide, AMI BWRO Membranes are Made in the USA in our ISO 9001:2015 Certified Facilities. Each reverse osmosis membrane element meets or exceeds our strict performance requirements before shipping. For the past 30 years we have earned a reputation of delivering consistent, high quality which makes AMI Membranes the natural choice for use in reverse osmosis water treatment systems.

Hard fiberglass exterior provides added strength and withstands higher pressure drops than tape-wrapped elements.
Reverse osmosis membranes remove up to 99% of total dissolved solids.
RO membranes remove dissolved impurities such as chloride, lead, chromate, fluoride, bacteria and others.
