RO systems typically have removal rates above 90%, and can even reach 99% for some contaminants. Mechanical filters, activated carbon filters, and ultrafiltration systems typically have lower removal rates, especially for dissolved substances and small organic molecules.

If there are more suspended matter in the water source, you can use a sand filter for preliminary filtration first, and then use a chlorine disinfection system for sterilization. This combination can effectively remove most pollutants and the cost is relatively low.

Reverse osmosis (RO) system is a technology that uses a semipermeable membrane to separate dissolved substances in water to achieve water purification. It has a good removal effect on various soluble pollutants, including organic matter, inorganic matter, metal ions, etc.

Small household ultrafiltration system: generally priced between $800 and $3,000, suitable for household daily water purification. Such systems usually have a processing capacity ranging from a few hundred liters to a few thousand liters per hour.

If the salinity in the drinking water source is high, such as salt water or groundwater in some areas, the use of reverse osmosis water purifiers is essential. RO technology can effectively remove dissolved salts in water and convert high-salinity water into low-salinity drinkable water.

Reverse Osmosis system is an advanced water treatment equipment that can remove a variety of pollutants such as dissolved salts, heavy metals, bacteria, viruses, etc. from water. The installation cost of a reverse osmosis system is relatively high, usually between $1,500 and $5,000.

Common types of water treatment equipment used in laboratories are 1. Reverse osmosis (RO) system 2. Deionization (DI) system 3. Ultrapure water system 4. Distilled water machine 5. Activated carbon filter 6. Ultraviolet disinfector

Household water consumption is the primary consideration for selecting the size of a water filter. Generally speaking, the water consumption of an average family is as follows: ● One-person family: about 200-300 liters/day ● Three-person family: about 500-600 liters/day ● Five-person family: about 800-1000 liters/day

UF systems are suitable for occasions with good water quality, demand for mineral retention, and low operating costs, such as household drinking water and agricultural irrigation. RO systems are suitable for occasions that require high-purity water sources, such as industrial water and medical.

RO systems used in clinics, laboratories or small medical institutions have a processing capacity of 500-1000 liters/hour and a price of US$5000-15000. Used in large hospitals or medical centers, with a processing capacity of more than 3,000 liters/hour, and a price of more than US$50,000.
