After the brand water purifier is installed as a white foam filter out of the water, the water purif

Franchisee to buy back from the agent has the same white foam filter out of the water after a water purifier installed a water purifier is not broken it? Experts said there is a water purifier installed after the white bubble is a normal phenomenon, it may be caused by the following reasons. First, the filtrate persist even micro filtration membrane hydrophilizing agent in order to ensure a measure of water permeability is, the surface of the filter membrane must show hydrophilic properties, but the film matrix is ??typically hydrophobic, it is necessary to take pro aqueous modifier to be modified. General hydrophilizing agents (protective solution) have some amphiphilic properties, the amphiphilic properties and facilitates the generation of a stable foam. In layman's terms, a more stable foam produced in the presence inevitably reflects the fact that: your filtrate persist even measure trace hydrophilic agent, and medical grade and food grade hydrophilic agent (protective solution) Basic health hazards no need to consider, so do not worry. Second, the purely physical phenomenon when pressurized water through the remote transport water pipe network water, under pressure, the gas existing in the pipe network as well as the atmosphere gas is increased in solubility in water, soluble in a large number of tap water; and tap water water into the apparatus must also be pressurized to increase the power through the pump, the pump body along with the water pressure, and dissolved in water by gas increases the pressure of the gas molecules becomes smaller, further increase the solubility. Since there has been pressure within the system, the gas molecules can not be released, when this part of the flow of water out of the system, the pressure on the gas molecules suddenly disappear, so they inflate the bubble has become our naked eye can be observed, there will be large when a large number of small bubble emission, the phenomenon appears milky water body, and then gradually disappear. This is a normal phenomenon purely physical, it will not affect the drinking water. Third, the water "whitening phenomenon" due to the pump and pumping process water partial repair process a certain amount of intake air, under pressure dissolved in water to form a fine bubble, when the water delivery pipes, water pressure and flow variations large, resulting in a large number of tiny bubbles entrained water from the tap water flowing out of the faucet, the surface looks like milk whitish color, to be allowed to stand for a few seconds, the bubbles disappear, the water becomes clear. This is a physical phenomenon does not affect water quality.
