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.

Advantages of reverse osmosis water maker: Wide applicability Improve the taste of drinking water Simple maintenance Environmental protection and energy saving Disadvantages of reverse osmosis water maker: Large amount of wastewater discharge Low efficiency of water resource utilization High energy consumption High cost of regular replacement of filter element and membrane Mineral loss High initial cost

The pore size of the reverse osmosis membrane is very small, about 0.0001 microns, so it can effectively filter out most ions, molecules and other impurities. Most dissolved solids (TDS), including hard water ions such as calcium and magnesium, can be effectively removed by the reverse osmosis system.

● 8040 reverse osmosis membrane: Due to its larger diameter, the surface area of ​​the membrane is usually between 365-400 square feet. ● 4040 reverse osmosis membrane: Due to its smaller diameter, the surface area of ​​the membrane is between 85-100 square feet.

Under-counter water purifier is a water purification device installed under the kitchen sink. Unlike traditional countertop water purifiers, it mainly saves space through hidden installation, and directly supplies filtered clean water through a special faucet or connected to the existing water pipe system of the home.

Components of portable desalination devices: 1. Water Intake System 2. Pre-treatment System 3. High-pressure Pump 4. Reverse Osmosis Membrane 5. Brine Disposal System 6. Freshwater Storage System 7. Power Supply System 8. Control System

The oil-water filter is a device specially designed to separate and remove oil pollutants from water. It is widely used in industrial wastewater treatment, oilfield reinjection water treatment, marine oil pollution treatment, and daily life occasions where oil pollutants need to be removed from drinking water.

Reverse osmosis membranes can be divided into many types according to the usage scenarios, membrane materials and processes. Different types of RO membranes differ in performance, durability and scope of application. Therefore, the membranes used in all RO equipment are not exactly the same.

The pore size of the reverse osmosis membrane is generally between 0.1 and 0.001 microns, which is enough to block most bacteria, viruses and dissolved ions. However, the solid particles in the mud are usually larger than this range, so in theory, the RO membrane can block these particles.

A water purifier is a device that removes impurities, dissolved substances and microorganisms from tap water or other water sources through advanced water treatment technology to produce nearly pure water. The working principle of a water purifier is usually based on reverse osmosis (RO) technology.
