This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,901.

Background and Problem Solved

The original patent, 'Controlled irrigation process and system for land application of wastewater', addresses the challenges of managing wastewater irrigation in land application systems. However, the existing system has limitations in terms of real-time monitoring, adaptability to changing weather conditions, and optimizing irrigation schedules. The present invention overcomes these limitations by introducing advanced sensors, real-time weather data integration, and a central controller for optimizing irrigation schedules and volumes.

Novelty and Inventive Step

The new invention introduces the concept of real-time weather data integration, advanced sensor networks, and a central controller for optimizing irrigation schedules and volumes, which are not present in the original patent. These features provide a significant improvement in efficiency, reduced contaminant loading, and optimized evapotranspiration, making the invention novel and non-obvious.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of machine learning algorithms to predict optimal irrigation schedules, integration with other wastewater treatment systems, or adaptation to different types of vegetation and soil conditions.

Potential Commercial Applications and Market

The advanced controlled irrigation system has significant commercial potential in the wastewater treatment and land application industries, particularly in regions with water scarcity or stringent environmental regulations. The system's ability to optimize irrigation schedules, reduce contaminant loading, and improve evapotranspiration makes it an attractive solution for municipalities, agricultural companies, and environmental organizations.
