Lanlang GAC KDF cartridge uses a unique three-stage multi-media system that incorporates the latest advances in water treatment technology. This system removes the widest spectrum of contaminants, rivaling the effectiveness of reverse osmosis and distillation systems costing two to four times more while preserving the beneficial minerals like calcium and magnesium.
STAGE 1 - MECHANICAL FILTRATION
Mechanical filtration is achieved when the dimension of the particle is larger than the hole in the filter. This form of filtration removes suspended particles, such as silt, sediment, sand, rust, dirt, and other undissolved matter. Our cartridge system employs a staged mechanical system that is measured in microns.
STAGE 2 - KDF 55 MEDIA
In the next stage, the water passes through a bed of a media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc KDF 55 MEDIA. Chlorine is instantaneously and almost inexhaustibly oxidized. Tests on our cartridge have shown 99+% chlorine removal past 20,000 gallons of water while a carbon cartridge of comparable volume drops below 90% effectiveness after only 4,000 gallons. Iron and hydrogen sulfide are oxidized into insoluble matter and attach to the surface of the media.
STAGE 3 - ADSORPTION: GRANULATED ACTIVATED CARBON
Granulated activated carbon (GAC) is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as herbicides, pesticides, industrial chemicals, and trihalomethanes (THMs). Carbon is extremely porous and provides a large surface area for contaminants to collect. We use a high-grade coconut shell carbon that is most effective at removing chemicals. Coconut shell carbon provides a significantly higher volume of micro-pores than either coal-, wood- or lignite-based carbon. As a result, it is more effective than other carbon types in removing trihalomethanes (THMs) and other chemicals from municipally supplied water.
