Household water filters have become one of the common appliances in modern households, used to provide clean and safe drinking water. However, water filters are not "one size fits all". There are many types of filtration systems inside them based on different functions and technologies.

Activated carbon filtration is one of the most widely used non-reverse osmosis water treatment technologies, especially in household water dispensers and filter jugs. It has a strong adsorption capacity and can remove organic matter, residual chlorine, odor and some heavy metals in water.

Radon gas is widely found in nature, especially in uranium-rich rock formations such as granite and shale. Radon in water mainly comes from groundwater. When groundwater passes through uranium-rich rocks, uranium decays to produce radon gas, which dissolves in the water.

If the rust particles in the well water are large, a filter of 10 to 20 microns can be selected; if the rust particles are fine, a filter of 5 to 10 microns should be selected.

For areas with complex water quality, such as high heavy metal content or more organic pollutants, reverse osmosis systems are the best choice. Its high-efficiency filtration capacity can ensure water quality safety, but you need to pay attention to its wastewater ratio and maintenance costs.

Feed is the main source of nutrition for livestock and aquaculture animals, and water is an important substance for their life activities. The quality of water directly affects the intake and digestion efficiency of feed, which in turn affects the growth and health of animals.

Reverse osmosis system is one of the most effective water filtration methods for removing phosphates. The pore size of the RO membrane is extremely small (usually around 0.0001 microns), which can prevent most soluble substances from passing through, including most ions including phosphates.

The following are several water filtration systems commonly used in hospitals: Reverse osmosis (RO) system Ultrafiltration (UF) system Deionized (DI) water system Activated carbon filtration system Ultraviolet (UV) disinfection system

Mechanical filtration is the most basic filtration method used to remove solid particles from water. Mechanical filters are usually composed of fine mesh, sponge or felt. When water flows through these filter materials, suspended particles are intercepted and captured.
