1. Look at the qualifications of laboratory integrated sewage treatment equipment. According to the drinking water hygiene supervision and management methods, products without health license approval are‘driving without a license’and are not protected by law.

       2. From a functional perspective, first clarify the purpose of selecting the equipment. Water purification is to remove sediment, impurities, residual chlorine and some minerals in the water. In order to choose the appropriateintegrated sewage treatment equipmentfunction, how to reasonably match the composition of the filter material is the key.

       3. Choose from the material, which is the material of the equipment tank. In terms of material selection, currently the main materials on the market are stainless steel, fiberglass, cast iron, aluminum, resin orPVC.

       Stainless steel, fiberglass, and cast iron are materials with relatively good pressure resistance and can be used as pre-filters, while materials such as aluminum, resin, orPVC等材料属于抗压性比较差的材质，只能用在前置过滤器的后端，用做直饮机使用。实验室integrated sewage treatment equipment这几种材质中，抗压性和耐腐蚀性以不锈钢为好。价位也相对较高。树脂或PVChave poor pressure resistance and are relatively low-priced. You can choose according to your needs.
