In this paper, we describe an experimental activity involving the water treatment steps using the activated carbon made from coconut fibre and grape pomace packaged in a filter constructed with low-cost material to adsorb chemical elements present in the underground saline water before desalination. The activated carbon (CA) was prepared with grape pomace (P) and coconut fiber (C) mixtures, with coconut/pomace doses of 100/0; 75/25; 50/50; 25/75; 0/100 (the first stage of the experiment). The 50C/50P mixture was statistically considered the most suitable for the production of CA, being chemically activated with ZnCl2, underflow of 100 mL/min, at 550ºC for 60 minutes. To evaluate the efficiency of the filter with the carbon produced, different contact times were used. Tests were performed every 5 minutes totalling 60 minutes. After the pH, EC, Na, K, Ca, Mg and Cl determinations in each collection and the corresponding statistical analysis, it was noticed that in the initial five minutes there was already positive response to adsorption of the determined elements.
