Final answer:
To avoid backsiphonage, reverse osmosis can be utilized. This process applies back pressure through a semipermeable membrane to reverse osmosis, filtering out unwanted substances from water. It is particularly effective for desalination and water purification.
Step-by-step explanation:
An alternative method that can be used to avoid backsiphonage is the process known as reverse osmosis. This technique involves creating back pressure sufficient to reverse the normal direction of osmosis through a semipermeable membrane. By applying this pressure, water is forced through the membrane which filters out dissolved substances, such as salt in the case of desalination. The effectiveness of reverse osmosis relies on the use of a membrane that is selective enough to prevent solute molecules from passing, while being able to withstand high pressures. Moreover, the technology of reverse osmosis is not only efficient but also widely used for converting sea water into potable fresh water.
