How to choose the chemicals for paper mill wastewater treatment

Paper mill wastewater is industrial sewage produced in the papermaking process, which contains a large number of organic and inorganic substances, if it is allowed to be discharged, it not only seriously pollutes the environment, but also causes a lot of harm to lakes, rivers and other waters. Therefore, the treatment of paper mill wastewater is very necessary. For the treatment of paper mill wastewater, the use of water treatment chemicals is an indispensable step. So how to choose the paper mill wastewater treatment chemicals? Paper mill wastewater commonly used water treatment chemicals are: flocculants, oxidizing agents, reducing agents, activated carbon, biological agents and so on. In papermaking wastewater treatment, we usually use flocculants for purification and treatment, let’s understand the role of flocculants. Flocculant is the suspended and colloidal matter in the water into large particles, so that it is easy to be filtered out by the filter, to achieve the purpose of filtration and purification, in the paper wastewater treatment, the use of flocculant can effectively remove organic and inorganic matter in the water, such as: pigment, pulp, etc., so as to reduce the value of its COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand) and so on. There are also commonly used flocculants such as polymerized iron sulfate, polymerized aluminum chloride and so on. The specific method of use is to mix the flocculant with the wastewater, after mixing, precipitation, filtration and other steps, you can achieve a better purification effect, in the paper mill wastewater treatment, the use of water treatment chemicals can effectively purify the water quality, reduce the indicators of COD and BOD, to prevent the paper wastewater from causing serious pollution of the environment, and the flocculant is a commonly used and effective water treatment chemicals, with a wide range of prospects for application.
