Stevia Wastewater Advanced Treatment Solution

Stevia, a natural sweetener, is widely used in various industries, including foodstuff, beverages, and pharmaceuticals. However, the wastewater generated during its production process presents a pressing challenge. This wastewater has a complex composition, containing not only high concentrations of organic pollutants but also acids and alkalis. Furthermore, due to differences in production processes, water quality fluctuates significantly, posing significant treatment challenges. Traditional wastewater treatment methods often fail to completely address the problem. Therefore, combining multiple technologies, particularly high-efficiency filtration equipment, is crucial for ensuring water quality meets standards.

Filter presses play a crucial role in stevia wastewater treatment. While the entire treatment process may include multiple steps, such as pretreatment and biological treatment, filter presses, as the core equipment for solid-liquid separation, are crucial for ultimately achieving water purification.

When treating stevia wastewater, the majority of contaminants are initially removed through processes such as aerated biological filters and sedimentation tanks. During this stage, PH adjustment and the addition of flocculants such as polyaluminum chloride and polyacrylamide effectively cause suspended solids and some organic matter to agglomerate into larger particles, forming flocs that are easily settled.

However, sedimentation alone is not sufficient to meet stringent discharge standards. To further remove fine suspended solids and difficult-to-settle flocs from the wastewater, a filter press plays an irreplaceable role. It uses mechanical pressure to trap solid particles in the wastewater on the filter cloth, while the clear filtrate flows through the cloth and is discharged. This process efficiently separates the solid and liquid phases, significantly reducing the suspended solids content in the effluent and also synergizing with the removal of chemical oxygen demand.

The filter press is the finishing touch in the stevia wastewater treatment process. After filtering through the filter press, the wastewater has an extremely low suspended solids content and is deeply purified, ensuring that the discharged water consistently meets national wastewater discharge standards, ultimately achieving the goals of water purification and environmental protection. Therefore, for any company seeking an efficient and reliable stevia wastewater treatment solution, choosing a high-performance filter press is a key step to ensure the success of its environmental protection work.
