水中硅的来源及处理
Source
Silica (SiO2) is an oxide of silicon, and is present in almost all minerals: It is found in surface and well water in the range of 1 - 100 mg/l. Silica is considered to be colloidal in nature because of the way it reacts with adsorbents. A colloid is a gelatinous substance made up of nondiffusible particles that remain suspended in a fluid medium. Silica is objectionable in cooling tower makeup and boiler feedwater. Silica evaporates in a boiler at high temperatures and then redeposits on the turbine blades. These deposits must be periodically removed or damage to the turbine will occur. Silica is not listed in the Primary or the Secondary Drinking Water Standards issued by the US EPA.
Treatment
The anion exchange portion of the demineralization process can remove Silica. Reverse osmosis will reject 85 - 90% of the silica content in the water.

来源矽(SiO2)是氧化的矽,是目前几乎所有的矿物质:人们发现,在地表水的范围和1100名自行车/L. 矽被认为是胶体的性质,因为这样的反应,adsorbents. 胶体物质的含量是由nondiffusible颗粒流体中仍然停顿了. 矽是不良的水塔和锅炉feedwater补课. 矽在锅炉高温蒸发然后redeposits的涡轮叶片. 这些存款必须定期清除或损坏的涡轮会出现. 矽未列入小学或中学的饮用水标准,美国环保局发布的. 负离子交换治疗的过程可以将电源部分骨骼. 反向渗透否决85-90%的矽含量的水.
