Multi-Layer Sand Filters
RAYNED series multi-layer sand filters represent the latest filter technology. It features durable corrosion-resistant and easy to operate. Working pressure is 2.5kgf/cm2. Beside silicon sand, other filtration material used include active carbon, ferromanganese, soft water resin, clean water resin and nitrate selectable resin. After processing, the filtered water well become odor-free, pure and clean. RAYNED series top-mount multi-purge sand filter is suitable for pre-treatment of ground water, well water, spring water and drinking water.
Magnetization water treatment implement
It is made of permanent magnetic material, in order to improve hardness of water quality by eliminating minerals such as Ca, Mg, Fe and Mn. It is widely used in all types of boilers, central air conditioners, condensers and water tanks to eliminate and prevent dirt. It is also used in swimming pools, landscape water and tap water to eliminate rust.
Soft water implement
It is made of JD filtration material and is able to eliminate minerals such as Fe, Mn, Ca and Mg, completely replacing ion exchange and become latest soft water purify equipment.
Filtration of eliminating Fe & Mn
The main equipment of the tank is made of voluble molding of glass fiber reinforced plastics, with filtration material inside such as quartz sand and manganese sand.
