Homeopathic dilutions. In homeopathy, homeopathic dilution (known by practitioners as dynamisation or potentisation) is a process in which a substance is diluted with alcohol or distilled water and then vigorously shaken in a process called succussion.
Since heat is vital in thermal desalination, the process is often linked to power plants and refineries to use waste heat. There are three main types of thermal desalination â vapour compression (VC), multi-effect distillation (MED) and multi-stage flash distillation (MSF).o create clean water using this process, seawater or brackish water is pressurized against one surface of the membrane, causing salt-depleted water to move across the membrane, releasing clean water from the low-pressure side.
