The methods of water treatment include physical treatment and chemical treatment.
The physical method includes the use of various filter materials with different pore sizes, and the impurities in the water are excluded by adsorption or blocking. The most important adsorption method is adsorption by activated carbon, and the blocking method is to pass water through the filter material to make the volume. Larger impurities cannot pass, resulting in cleaner water. The chemical method uses various chemicals to convert impurities in water into substances that are less harmful to the human body, or concentrates impurities. After the impurities in the water are collected, the volume becomes larger, and the impurities can be removed by filtration.

Reverse osmosis is a membrane separation technique that uses pressure as a driving force by selecting a function of permeating (semi-transmissive) membrane. When the pressure applied in the system is greater than the osmotic pressure of the aqueous solution, the water molecules continuously permeate the membrane. The impurities flowing into the central tube through the product water channel and then flowing out of the water at one end, such as ions, organic matter, bacteria, viruses, etc., are trapped on the water inlet side of the membrane, and then flow out at the concentrated water outlet end, thereby achieving the purpose of separation and purification.

Ultrafiltration water treatment equipment is a membrane separation process with pressure as the driving force. The micropores of the membrane surface can be used to intercept particles and impurities between 0.002-0.1μm in diameter, which can effectively remove colloid, silicon, protein and microorganisms in water. And macromolecular organics.
