AI Technical Summary

Technical Problem

The activated sludge method for wastewater treatment faces challenges such as inefficient oxygen utilization, excessive sludge production, and the formation of undesirable greenhouse gases, limiting its effectiveness and scalability.

Method used

A system and method that separately control and prioritize the reproductive and digestive functions of microorganisms by creating a near-starvation state, using pure oxygen or oxygen with ozone to activate microorganisms, and forming ultra-fine bubbles to enhance oxygen availability and direct biochemical pathways that consume less oxygen and produce inert byproducts.

Benefits of technology

This approach significantly enhances wastewater treatment capacity, reduces excess sludge production, and achieves greater organic matter purification with less energy consumption, making it more efficient and cost-effective than traditional methods.

Abstract

------20 / 04 / 2565------(OCR) Increased control and efficiency in wastewater purification (II) can be achieved by creating conditions that allow operators to specifically prioritize the digestion functions of microorganisms in activated sludge. Return sludge with gas dispersion (36) is created using reactive gases (37) which are mixed with sludge (21) to create a gas-liquid mixture which is then passed through an atomizer (24) or a cavitation pump (22) to immediately convert the reactive gases (37) into an ultrafine bubble state. At least some of these ultrafine bubbles are dissolved within the return sludge with gas dispersion (36), activating the dormant microorganisms. Because there are no completely or nearly completely biodegradable materials in the return sludge with gas dispersion (36), the microorganisms prioritize their digestion functions and, upon contact with biodegradable pollutants present in the wastewater (11), digest the pollutants using different biochemical pathways than those used in nature. ------------ DEPCT65 Increased control and efficiency over wastewater (11) Purification can This is done by creating conditions that allow operators to prioritize their selections. The importance of microbial digestion in activated sludge, sludge return, and gas distribution (36). It is created using reactive gas (37) which is mixed with sludge (21) to create a gas mixture and The liquid is passed through a water jet (24) or a cavitation pump (22) to immediately produce a reactive gas (37) that is bubbly. In a very fine state, at least a portion of the ultra-fine air bubbles will be dissolved within the sludge. Returning gas distribution (36) stimulates dormant microorganisms due to the absence of biodegradable material. Completely or nearly completely biological in sludge return gas distribution (36) microorganisms Prioritize digestion and exposure to present biodegradable pollutants. In wastewater (11), microorganisms break down pollutants using different biochemical pathways than those used in nature. -----------------------------------------------------------
