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.

Biological Filtration Media for Wastewater Treatment is a material used to support the formation and maintenance of biofilms. Its function is to provide an ideal physical carrier for the growth of microorganisms.

The filter is used to treat slurry by filtration, and is usually installed in the path of the slurry flow to intercept the solid particles in it. The filter element or filter screen of the filter needs to be cleaned or replaced regularly to ensure the treatment effect.

A salt water chlorinator (Salt Chlorinator) is a device that produces chlorine gas by electrolyzing a salt water solution (NaCl solution), which is widely used in water bodies that need to be disinfected. Its core function is to convert ordinary salt into sodium hypochlorite (NaClO)

The industrial UV water purification filter is a device specially used for industrial water purification. It mainly uses ultraviolet (UV) technology to inactivate microorganisms in water to achieve the purpose of purifying water quality. This filter is usually used in industrial fields that require highly pure water sources

For small home users, a water softener that can treat 10-20 liters of water per minute is sufficient, while a larger home or commercial location may require a larger capacity unit. The larger the capacity, the higher the price of the water softener. For example, a water softener with a larger capacity may cost up to $3,000 or more.

The household's water consumption and the frequency of use of the water filter directly affect the life and cleaning cycle of the filter element. If there are many family members and the water consumption is high, the filter element of the water filter will accumulate dirt faster and need to be cleaned more frequently. Generally, it is recommended to clean a water filter with high usage frequency every 1-2 months.

Reverse osmosis seawater filters are currently the most commonly used seawater filtration equipment. Its core technology is based on reverse osmosis membranes, which apply high pressure to force water molecules through the membrane, leaving behind salt and other impurities.

The treatment methods for aquaculture wastewater mainly include physical treatment, chemical treatment and biological treatment. Different treatment technologies can be used for different pollutants in wastewater.

Filtered water refers to water that has been treated to remove impurities and pollutants. Usually, the technologies used in water filtration equipment on the market include activated carbon filtration, reverse osmosis, ultraviolet disinfection, etc.
