Severe water pollution has been a prerequisite for promoting the development of water vending machine, water vending machine manufacturers through a variety of experimental study of updated technology makes it the taste of water purification equipment to purify water, colorless and tasteless, easy to operate, affordable price of and improve the service system, and constantly improve, to obtain the majority of consumers of the pro-Lai and trust. Water vending machine manufacturers use development to ensure people's health as a precondition, superb technology, the success of products and professional services for the community to provide quality water purification products, health concerns, environmental protection has become a firm support to realize sustainable development and strong backing. Machine supplies using the installation is the core technology of the machine, in addition to use pp cotton were the first, * use of the machine, followed by the third grade granular activated carbon, respectively, the fourth part of this would be compressed activated carbon pre-filter machine supplies using RO membrane filtration using precision behind these supplies in the next post filter using supplies water quality to improve the taste, to achieve water quality beneficial elements, and finally to be sterilized, water purification out so you can drink.
