Book Description
The crew of Ngarra’s deep sea mining Skimmer are at Xed Ocean Academy under the watchful eye of officials and soon to return to sea. Previously, they had been pursued at sea for a technology one of the crew developed that enabled Xtract mining drones to learn autonomous group behaviour. Chang, a crew member, is convinced his sister Ying Yue is in danger. She works onboard the Chinese-owned GlobeCorpMining deep-sea mineral Harvester and is developing a technology that has the potential to undermine the Skimmer crew program. Chang becomes a pawn that is played by all sides, culminating in a face off at the Harvester. As brother and sister struggle with family history, it becomes apparent that there is more to the Skimmers than the crew is led to believe.

Book Description
Duckweed is a floating aquatic plant that has been used in a variety of water treatment applications. The plant must be harvested for the chemical removal from the wastewater to be complete. This project investigated the suitability of a harvesting system that would collect the plants by skimming them from the water surface to maintain the crop at a desirable density. The observation was made that clumps of plants could form, as opposed to a single layer of individual plants, which affected the skimming of the duckweed mat. Experiments were performed to find the necessary depth and slope of the skimmer for clumps to move in at very low flows. The skimmer crest was rounded and the root length of the plants ranged between 0 and 6 cm. A depth of approximately 1.5 cm was found to be the minimum depth where clumps moved into the skimmer consistently. The skimmer slope could be 3o with clumps still flowing down the skimmer base. A concept and full-scale prototype were developed. The prototype used a skimming funnel that floated beneath the duckweed mat. A pumping mechanism was connected to the funnel that pumped to the bank. A vortex formed over the funnel orifice during pumping, which moved plants into the funnel and exit pipe. Flow data was collected at various funnel depths and author-defined vortex strengths were noted. Using the data, empirical equations were found that could be used to calculate the needed pumping rate to achieve a desired vortex strength at a given funnel depth. Experiments were conducted to evaluate the circulation of the duckweed mat and thus the ability of a skimmer-based harvester to harvest from all areas of the water surface. Tracers were placed on the duckweed mat and natural wind forces and flow forces from the skimmer were applied. The tracers were then monitored for approximately 2 weeks. Some movement occurred, but there was no consistent rotation in the plant mat. It was determined that duckweed could be harvested well using skimmers, y.

Book Description
Industrial Waste Treatment Handbook provides the most reliable methodology for identifying which waste types are produced from particular industrial processes and how they can be treated. There is a thorough explanation of the fundamental mechanisms by which pollutants become dissolved or become suspended in water or air. Building on this knowledge, the reader will learn how different treatment processes work, how they can be optimized, and the most efficient method for selecting candidate treatment processes. Utilizing the most up-to-date examples from recent work at one of the leading environmental and science consulting firms, this book also illustrates approaches to solve various environmental quality problems and the step-by-step design of facilities. Practical applications to assist with the selection of appropriate treatment technology for target pollutants Includes case studies based on current work by experts in waste treatment, disposal, management, environmental law and data management Provides glossary and table of acronyms for easy reference
