Oil production involves several operations that generate environmental impact. One of them is the necessary separation, before marketing, of the water that comes associated to the oil. Volume and composition of production water depend specifically on the reservoir from which it comes. Traditionally, API separators and corrugated plates are used to carry out the treatment;…
Advanced Oxidation Processes (AOP) Advanced oxidation process es ( AOP s) have been defined by Glaze etal . as processes that “ involve the generation of hydroxyl radicals in sufficient quantity to effect water purification ” . AOPs are used to specifically generate OH ° . The OH ° have a higher oxidation potential (2.8…
This review article organizes the studies conducted on the areas of microbubbles and nano bubbles with a special emphasis on water treatment. The basic definitions of bubble types and their size ranges are also presented based on the explanations of different researchers. The characterization parameters with state-of-the-art measuring and analysis techniques of micro-bubble and nanobubble…
Concentration polarization (CP) is a major operational challenge for reverse osmosis (RO) desalination because it results in decreased permeate flux and increased transmembrane pressure (TMP). In this study, lab-scale and pilot-scale cross-flow filtration experiments were performed to evaluate the impact of air micro-nano bubbles (MNBs) on permeate flux, TMP and solute rejection. Results indicated that…
The textile finishing industry gives fabrics and garments their final appearance and properties. It employs traditional processes that are not environmentally friendly. These industrial activities have some environmental consequences, mainly related to the massive consumption of chemicals and intensive use of water and energy resources, waste-water treatments required, etc. Processes like desizing, bleaching, washing (roll-to-roll…
When the REO laboratory (Matsushima City) applied the technology of supermicrobubble “Nanobubble” to rice farming, The experiment was successful. It was proven that the growth of the rice plant was also active and act as a strong assistant to organic farming. This laboratory is advancing the research that applies the nanobubble to agriculture, aquaculture, and…
