水处理的方式包括物理处理和化学处理。人类进行水处理的方式已经有相当多年历史，物理方法包括利用各种孔径大小不同的滤材，利用吸附或阻隔方式，将水中的杂质排除在外，吸附方式中较重要者为以活性炭进行吸附，阻隔方法则是将水通过滤材，让体积较大的杂质无法通过，进而获得较为干净的水。另外，物理方法也包括沉淀法，就是让比重较小的杂质浮于水面捞出，或是比重较大的杂质沉淀于下，进而取得。化学方法则是利用各种化学药品将水中杂质转化为对人体伤害较小的物质，或是将杂质集中，历史最久的化学处理方法应该可以算是用明矾加入水中，水中杂质集合后，体积变大，便可用过滤法，将杂质去除。

The way water is treated includes physicalprocessing and chemical treatment. The ways in which human water treatment havebeen years of history, physical methods including the use of a variety ofdifferent aperture size, the filter material using adsorption or blocking way,exclude the impurities in the water, the adsorption mode of less important foradsorption on activated carbon, blocking method is through the water, thefilter material for large impurity cannot pass, and get more clean water. Inaddition, the physical method also includes precipitation method, which is tomake the impurity of the smaller proportion floating in the water, or theimpurities of the larger proportion are deposited in the lower, and thusobtained. Chemical method is to use various chemicals to the water impuritiesinto smaller material harm to the human body, or the impurity concentration,the oldest of the chemical treatment method should be use alum in the water,the water impurities after collection, volume change, used to filter method,remove the impurities.
