Features of industrial wastewater are mainly manifested in large discharge volume, complex composition and serious pollution. The two most important pollution indicators are commonly used to express the quality of wastewater, that is, suspended solids and chemical oxygen demand. The water quality of different industrial wastewater varies greatly. Taking chemical oxygen demand as an example, the lower is between 250-3500 mg/L, and the higher is often tens of thousands of milligrams per liter, or even hundreds of thousands of milligrams per liter.
The pollution hazards caused by industrial wastewater to the environment, and the prevention and control measures that should be taken, depend on the characteristics of industrial wastewater, that is, the type, nature and concentration of pollutants. The water quality characteristics of industrial wastewater vary not only according to the type of wastewater, but often change with time and place.
Solutions of industrial wastewater
Select the appropriate treatment process and related equipment according to the wastewater volume and water quality to ensure that the wastewater can be effectively treated to meet the discharge standards, and energy consumption and economic investment can be saved.
Holy shield can provide you with the following list of key equipment, and provide customized service and installation instructions:
