Distillation's effectiveness in removing organic compounds varies, depending on such chemical characteristics of the organic compound as solubility and boiling point. These harmful compounds will recontaminate the purified product if not removed prior to condensation. Figure 1 shows the parts and process of a distiller. Parts and process of a distiller. They are generally placed at the kitchen faucet and used to purify water for drinking and cooking only.
Size varies, depending on the amount of purified water they produce.
Production rates range from 3 to 11 gallons per day. Home stills can be located on the counter or floor, or attached to the wall. Models can be fully or partially automated, or manual. Some units have columns or volatile gas vents to eliminate organic chemicals with boiling points lower than water, thus ensuring uncontaminated water. Operation, Maintenance and Cost As with all home water treatment systems, distillation units require some level of regular maintenance to keep the unit operating properly.
