The CCAD is located on the Corpus Christi Bay and has an abundant supply of seawater. The CCAD s advanced metal finishing facility utilizes reverse osmosis to desalinate seawater. Reverse osmosis consists of forcing saline water through a semi-permeable membrane. If seawater is not readily available, mix one gram of salt to one liter of deionized water. Coffee filters are suggested to use because they are inexpensive, however, filter paper may be used instead.
