Oil Production Water Treatment by Dissolved Air Flotation

By NANOBBLE

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;…

Understanding Advanced Oxidation Processes ( AOP ) in Detail

By NANOBBLE

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…

CIP (Cleaning in Process) of RO (Reverse Osmosis) Membranes using Micro Nano Bubbles to reduce Membrane Fouling and longer Membrane Life – Non Chemical Method of Membrane Fouling Removal & RO Membrane CIP

By NANOBBLE

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…
