水處理的方式包括物理處理和化學處理。人類進行水處理的方式已經有相當多年歷史，物理方法包括利用各種孔徑大小不同的濾材，利用吸附或阻隔方式，將水中的雜質排除在外，吸附方式中較重要者為以活性炭進行吸附，阻隔方法則是將水通過濾材，讓體積較大的雜質無法通過，進而獲得較為干凈的水。另外，物理方法也包括沉淀法，就是讓比重較小的雜質浮于水面撈出，或是比重較大的雜質沉淀于下，進而取得。化學方法則是利用各種化學藥品將水中雜質轉化為對人體傷害較小的物質，或是將雜質集中，歷史最久的化學處理方法應該可以算是用明礬加入水中，水中雜質集合后，體積變大，便可用過濾法，將雜質去除。

 The way water is treated includes physical processing and chemical treatment. The ways in which human water treatment have been years of history, physical methods including the use of a variety of different aperture size, the filter material using adsorption or blocking way, exclude the impurities in the water, the adsorption mode of less important for adsorption on activated carbon, blocking method is through the water, the filter material for large impurity cannot pass, and get more clean water. In addition, the physical method also includes precipitation method, which is to make the impurity of the smaller proportion floating in the water, or the impurities of the larger proportion are deposited in the lower, and thus obtained. Chemical method is to use various chemicals to the water impurities into 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.
