Increasingly, the demand for quality water is growing, and finding alternative ways for wells water treatment is under way. The purpose of this study is to apply activated carbon at the wells water treatment, whereby several parameters are measured such as pH, electric conductivity, total chlorine and iron, before carbon-activated treatment and after being treated with activated carbon. From the observed testing results, a change in results after the treatment phase was observed: a decrease in electrical conductivity in all samples, as well as in all samples treated we got an increase in pH value and total chlorine, whereas in the iron property there are some variations in results. Practical laboratory procedures on the water samples treatment with activated carbon has been carried out at the UBT Laboratories, Food Science and Biotechnology Lab.
