AI Technical Summary

Technical Problem

Existing granular sludge reactors in aerobic mode face challenges such as complex management, long operational times, and structural requirements that make them difficult to adapt to existing sewage treatment plants, particularly due to the need for high oxygen levels and shear/compression forces to produce Extra-cellular Polymeric Substances (EPSs) essential for granular sludge formation.

Method used

A compact apparatus with a bell-shaped structure that introduces air to create a flow from a large inlet to a smaller outlet, generating shear and compression forces and increasing oxygen levels, allowing for controlled production of EPSs within a reactor, which can be integrated into existing sewage treatment plants.

Benefits of technology

This solution enables efficient degradation of organic sewage fractions by promoting EPS production, reducing energy costs, and facilitating easier sludge separation and dehydration, while being adaptable to both continuous and intermittent feeding systems.

Abstract

The invention relates to an apparatus for degrading the organic fraction of wastewater by means of an active biomass, in particular particles of activated sludge, comprising: - at least one tank (1) designed to contain the wastewater and said active biomass; - at least one hollow structure (6, 106, 206), designed to be at least partially immersed in the wastewater, provided with at least one first opening (61) for letting the wastewater in and at least one second opening (62) for letting the wastewater out, the ratio between the area of ​​said at least one first opening (61) and the area of ​​said at least one second opening (62) being equal to at least 5:1; - air distribution means (7, 70) designed to introduce air into said at least one structure (6, 106, 206);said at least one first opening (61) being proximal to said air distribution means (7, 70) and said at least one second opening (62) being distal to said air distribution means (7, 70), so that the air distribution means (7, 70) are designed to generate a flow of wastewater from said at least one first opening (61) to said at least one second opening (62).
