The AK H Series of thin-film reverse osmosis (RO) elements provides all of the features expected of high performance low energy elements including very high rejection, low operating pressure, and longer element life-times. These AK H Series brackish water elements also offer very high rejection of uncharged and lightly charged species including silica and many micropollutants. AK H Series elements combine Veolia chemistry and manufacturing advancements to deliver differentiated performance that is ideal for any brackish water salinity with applications such as drinking water treatment for removal of emerging contaminants and second-pass RO systems in front of further polishing by ion exchange or electrodeionization. AK H Series elements are a reliable source of energy savings with minimal compromise in contaminant removal.
All AK H Series elements have NSF/ANSI/CAN 61 certification and 8-inch diameter elements also have halal certification.
