## 3 Results and Discussion  
### Sawaater Treatment Results  
Fluids collected before and after the ASE&C treatment were analyzed. Table 1 summarizes water parameters at the input and output of the ASE&C system. All the dissolved elements were almost completely removed (most of them below the analytical detection limit) to obtain distilled water with pH modified from 7.9 to 5.2, EC from 56 mS/cm to 142 uS/cm, and the Langelier index from 0.79 to \(-\)5.85.  
Figure 2: ASE&C\({}^{\text{TM}}\) flowchart diagram with energy feedback through vapor compression. 1. Inlet of the heat transfer fluid to the evaporator. 2. Inlet of the fluid to be processed (raw water) to the evaporator. 3. Output of the processed fluid (vapor) from the evaporator. 4. Heat-carrying fluid outlet from the root compressor. 5. Processed fluid (vapor) outlet from the root compressor to the heat exchanger. 6. Processed fluid (condensed) outlet from exchanger; after the fluid is condensed in the heat exchanger, it is deposited in two condensate tanks, and then taken to the condensate heat exchanger. 7. Exit of the heat transfer fluid after being heated by the exchanger. 8. Outlet of the processed fluid from the condensate heat exchanger. 9. Outlet of the fluid to be processed (raw water) from the condensate heat exchanger. 10. Input of the fluid to be processed to the condensate heat exchanger.  
The values obtained for the crystallized salts formed are given in Table 2. Microbiological presence was not detected in the solid residue. Most of the newly formed conglomerates were chlorides (53%); 80.50% of the dried residue composition was NaCl, together with sulfates (4.80%), and Mg (3.34%).
