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.

Well water and groundwater usually contain more silt, rust and organic matter, and the hardness is also high. In this case, it is recommended to install a mechanical filter or activated carbon filter first, and then install a water softener to ensure a comprehensive improvement in water quality.

Reverse osmosis (RO) technology is considered to be one of the most effective water treatment methods. Reverse osmosis technology uses semipermeable membranes to efficiently remove dissolved salts, organic matter and microorganisms in water, and can provide high-quality purified water.

Countertop water purifier is a small water purification device installed on the kitchen countertop, usually directly filtered by connecting to the faucet or water source. Its core working principle includes: pre-filtration, activated carbon filtration, ultrafiltration membrane filtration etc..

Flat sheet ultrafiltration membrane is a membrane separation technology that intercepts suspended matter, microorganisms, colloids and macromolecular organic matter in water under external pressure through a semipermeable membrane, thereby achieving the process of water purification.

Common water filtration media are: 1. Activated carbon 2. Sand filtration and gravel filtration 3. Ceramic filter element 4. Ion exchange resin 5. Ultrafiltration membrane 6. Reverse osmosis membrane Emerging water filtration media are: 1. Graphene membrane 2. Biofilter

First, it improves the production efficiency and product quality of enterprises and enhances their competitiveness; second, it saves water costs and reduces production costs; third, it meets environmental protection requirements and enhances the social responsibility image of enterprises.

The micron rating of commercial ultrafiltration membranes is approximately 0.01 micron. This fine pore size allows commercial ultrafiltration membranes to effectively filter tiny particles and organic substances in water, ensuring the purity and safety of the effluent.

Filtration is a method of separation using filter media. Filters are typically able to remove particles as small as about 1 micron, but are unable to remove some dissolved chemicals. Ultrafiltration is a filtration method based on hollow fiber membranes. Ultrafiltration membranes have very tiny pore sizes, usually between 0.01 and 0.1 microns, and are able to filter out even smaller particles and microorganisms, and even viruses and most bacteria.

This article provides an in-depth analysis of the role of filtration membranes in reverse osmosis water treatment systems. The filter membrane is constructed using high-tech materials and achieves efficient desalination through a microporous structure, intercepting microorganisms, removing suspended substances, and ensuring water quality.
