Today, let’s explore the benefits of combined settling tanks and filters for wastewater treatment. The combination of a lamella settling tank and a drum filter combines the best of both technologies for optimal results. Here are the essentials: Advantages of the technologies ➡️Lamella settling tank: Ideal for handling high pollution loads, particularly organic and particulate. However, it shows its limitations with high flow rates, because small particles can be carried along with the flow. ➡️Drum filter: Efficient for handling high flow rates, often used in aquaculture. Its main disadvantage is clogging when saturated with small particles. Why combine them? Their combination allows you to exploit the best of both: the settling tank treats heavy loads and the filter manages higher flow rates. This is particularly effective for plants with large variations in average and peak flow rates. When to choose which solution? ▶Constant and smooth flow: A simple lamella clarifier can be sufficient. ▶Strict suspended solids standards: If the requirements are lower than the usual standards (20 or 15 mg/l), it may be necessary to add a drum filter in addition to meet these standards. ▶High suspended solids loads: In case of loaded flow, consider coagulation-flocculation before the clarifier. This step helps to trap particles more efficiently, thus reducing the load on the drum filter. Do you want to size your own installation?

In summary, the clarifier-filter combination is a flexible and efficient solution for plants that have to deal with flow variations or strict water quality requirements. To choose the best option, it is necessary to evaluate the characteristics of the effluents, the standards to be respected, and the profitability of the project. #Watertreatment #FilterDecanter #EnvironmentalInnovation #WaterManagement #HydraulicEfficiency
