Description

The calculation for the UASB reactor optimizes the design and operation of the system by efficiently treating effluents, estimating organic load, sludge production, and flow dynamics based on the physicochemical characteristics of the influent.

 

Volumetric Organic Load: Calculated from the average influent flow and the influent chemical oxygen demand (COD) to estimate the effectiveness of the anaerobic treatment.

 

Sludge Production and Concentration: Determined by the solid production coefficient and sludge density, essential for waste management planning.

 

Reactor Dimensions: Defined by the reactor height, the width of the openings for the settler, and the external width of the gas collectors, fundamental for structural and functional design.

 

Volumetric Hydraulic Load and Distribution: Calculated using the reactor dimensions to optimize the effluent distribution and treatment efficiency.

 

Settler Area and Number of Tubes: Estimated to ensure efficient sludge separation and effluent clarification.

 

Hydraulic Retention Time and Surface Velocities: Designed to ensure adequate contact time and correct solid sedimentation, as well as to optimize biogas capture.
