Khalifa University's Center for Membranes and Advanced Water Technology (CMAT) has developed 3D-printed spacers for RO and UF membranes. The team has designed spacers called "triply periodic minimal surfaces" (TPMS) that are curved and thinner than traditional mesh-type spacers, lowering the pressure drop and allowing for greater membrane surface area in a module. As a result, membranes experience higher flux (16% for RO and 38% for UF), which directly translates to lower energy costs and higher water output. Also, the occurrence of biofouling can be reduced by up to 91%. Clients should investigate the advancements in 3D printing for the membrane market, including players like Aqua Membranes and research development at Khalifa and UConn.
