1. Quartz sand filter: The equipment is a hermetically sealed chamber made of stainless steel which is set inside gritted rod, therefore get filtrated and clean. 2.Activated carbon filter: The filter is designed for drinking water treatment. It can clear away alien colour and foreign substance from the water and can remove heavy metal such an mercury, lead, cadmium, zinc, iron, manganese and hydrogenate, sulphide, small amount of remaining chlorine and so on. 3. Micro filter: Series precise filter composes of stainless steel enclosure and filter core whose precision grade ranges 0.1um-100um for protecting the reverse osmosis membrane from particles, and is also used for removing bacterium and clarifying in medicine and wine. It requires replacing the filter core when the input and output water pressure difference exceeds 0.1MPa after using for 1-6 months. 4. Ro- reverse osmosis pure water equipment remove the grain, impurity and residual chlorine tap water through reasonable and high efficient pre-treatment system, then remove microbe such as bacteria, virus and most ion of heavy metal that is harmful to human body with separation technology of hi-tech. Reverse osmosis film, which can directly used to wine to mix water of manufacture use. This pure water is applied to food, dairy, and all sorts of soft beverage and water preparation of distilled spirit, beer and sherry. With the improvement of life quality and sanitary requirement, people bring forward higher and higher requirement of water quality for products such as all sorts of soft beverage, food, dairy and wine, especially for taste and sanitary standard. It not only keep the special pure and aromatic of beer and sherry, but reduce process of techniques, save energy consumption and decrease cost.
