Challenges are being faced to get fresh water for the areas having a low amount of usable water. This study aims to asses and evaluates the feasibility of removing nitrate from groundwater by using cheap approaches. A pilot-scale solar distillation membrane filter, was designed and constructed for this study, the set up was designed into two partitions: i) water heater and ii) membrane distillation. The effect of several operating parameters such as feed and distillate temperature, nitrate concentration, and pH, on water flux and nitrate removal efficiency, was investigated. The results showed that 85 and 93 percent removal efficiencies for nitrate and total dissolved solids, respectively. The effect of important parameters of solar performance membrane filter distillation (SPMFD) process including solar collector efficiency ( ), gained output ratio (GOR) and significant operating parameters containing feed and condensate temperature, feed nitrate concentration and pH were studied in this work and it could be concluded that water flux was increased exponentially with increasing feed temperature, and under the same operating conditions, average water flux changed from 9.52 to 34 kg/m2 per hour when temperature increased
