In March 2009, Pure Aqua, Inc. designed and manufactured two industrial RO machines for Canadian Nexen Petroleum Yemen. These RO machines were chosen from our RO-400 series and came complete with pretreatment consisted of multimedia filters and antiscalant chemical dosing units. An integrated flushing system was included on the same RO skid. For more information click here: http://www.pureaqua.com/reverse-osmosis-systems.html
