Adsorption refers to the process by which one substance attaches to the surface of another substance. Specifically, adsorption uses the surface of porous materials to attract and fix pollutants in water on its surface, thereby separating these pollutants from the water body.

If the filtered water quality is significantly reduced, the TDS value (total dissolved solids) is increased, or the water outlet speed is significantly slowed down, the reverse osmosis membrane should be considered for replacement.

Activated carbon filtration is one of the most widely used non-reverse osmosis water treatment technologies, especially in household water dispensers and filter jugs. It has a strong adsorption capacity and can remove organic matter, residual chlorine, odor and some heavy metals in water.

A standard water treatment system usually consists of a pretreatment unit, a core treatment unit, a post-treatment unit, and auxiliary equipment. These parts work together to ensure that the water quality meets the expected standards.

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.

The water quality standards used in agricultural irrigation are different from those for drinking water. Generally speaking, agricultural irrigation water does not need to meet the high standards of drinking water, but it must meet the growth needs of crops and cannot cause adverse effects on soil and plants.

Watermark is a certification mark that indicates that the product meets specific quality, safety and performance standards. The certification is awarded by relevant regulatory agencies in Australia and New Zealand to ensure that water-related products are safe and reliable during use.

For a water filter with a nominal processing capacity of 500L/hour, it means that under ideal conditions, it can process 500 liters of water per hour. However, flow rate does not fully represent the filtration rate, and the filtration effect needs to be considered.

Although industrial distilled water is superior to conventional drinking water in purity, it is not recommended as daily drinking water because it lacks necessary minerals and may have secondary pollution and microbial risks.

Water dispensers with water purification function are usually equipped with multi-stage filtration systems, including pre-filtration, activated carbon filtration, ultrafiltration or reverse osmosis. The pre-filter can remove large particles of impurities
