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,' addressed the challenges of managing wastewater in land application systems. However, its scope was limited to a specific application. This invention disclosure expands the core technology to tackle wastewater management in diverse industries, providing a more comprehensive solution for sustainable wastewater reuse.

Novelty and Inventive Step

The new claims introduce novel applications and use cases that were not originally considered, demonstrating an inventive step beyond the original patent. The adaptation of the controlled irrigation process to these diverse industries and problems solves specific challenges and provides unique benefits, such as increased crop yields, reduced wastewater discharge, and improved water conservation.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include integrating sensors for real-time monitoring of soil water tension, incorporating machine learning algorithms to optimize irrigation protocols, or developing modular systems for easy deployment in various industries. Variations of the invention could also focus on specific industries, such as agriculture, aquaculture, or golf course management, to provide tailored solutions for wastewater reuse.

Potential Commercial Applications and Market

The invention has significant commercial potential in various industries, including urban agriculture, decentralized aquaculture, vertical farming, and golf course management. The market demand for sustainable wastewater reuse solutions is growing, driven by increasing concerns about water conservation, environmental sustainability, and public health. The invention's adaptability to diverse applications positions it for widespread adoption and potential partnerships with industry leaders.
