The Formation, Stabilization and Separation of Oil–Water Emulsions: A Review

Processes, Journal Year: 2022, Volume and Issue: 10(4), P. 738 - 738

Published: April 11, 2022

Oil–water emulsions are widely generated in industries, which may facilitate some processes (e.g., transportation of heavy oil, storage milk, synthesis chemicals or materials, etc.) lead to serious upgrading environmental issues pipeline plugging, corrosions equipment, water pollution, soil etc.). Herein, the sources, classification, formation, stabilization, and separation oil–water systematically summarized. The roles different interfacially active materials–especially fine particles–in stabilizing have been discussed. advanced development micro force measurement technologies for emulsion investigation has also presented. To provide insights future industrial application, by methods summarized, as well introduction equipment combined processes. gaps between demulsification applications touched upon. Finally, perspectives treatment technology discussed purpose achieving high-efficiency, energy-saving, multi-functional treatment. We hope this review could bring forward challenges opportunities research fields petroleum production, coal iron making, protection, etc.

In-Depth Photocatalytic Degradation Mechanism of the Extensively Used Dyes Malachite Green, Methylene Blue, Congo Red, and Rhodamine B via Covalent Organic Framework-Based Photocatalysts

Water, Journal Year: 2024, Volume and Issue: 16(11), P. 1588 - 1588

Published: June 1, 2024

Photocatalytic degradation technology has received much attention from researchers in the last few decades, due to its easy and cost-effective nature. A lot of review articles have been published on dyes via photocatalytic degradation, but most lack a detailed in-depth mechanism dyes. Numerous are available photocatalysis. Here, this article, we mainly focused complete four commonly used such as Malachite Green, Methylene Blue, Congo Red Rhodamine B, which will be highly useful for new that work dyes’ degradation. Initially, various aspects included comprehensively. The main focus was covalent organic framework-based photocatalysts their porous nature unique properties. Various synthesis routes performance frameworks composite highlighted article. In section stimulus mentioned properties, uses, toxicity, through paths into environmentally friendly less-harmful compounds presence photocatalysts. Factors effecting economic cost, challenges future were also This article those search complex dye molecules.

Petroleum Hydrocarbon Removal from Wastewaters: A Review

Processes, Journal Year: 2020, Volume and Issue: 8(4), P. 447 - 447

Published: April 10, 2020

Oil pollutants, due to their toxicity, mutagenicity, and carcinogenicity, are considered a serious threat human health the environment. Petroleum hydrocarbons compounds, for instance, benzene, toluene, ethylbenzene, xylene, among natural compounds of crude oil petrol often found in surface underground water as result industrial activities, especially handling petrochemicals, reservoir leakage or inappropriate waste disposal processes. Methods based on conventional wastewater treatment processes not able effectively eliminate high concentrations these well active sludge, may affect activities normal efficiency refinery. The methods removal should involve production harmful secondary pollutants addition at level allowed discharge into output sewage filtration by coagulation dissolved air flotation (DAF) flocculation can be transferred biological reactor further purification. Advanced such electrocoagulation more advanced than physical chemical methods, but major disadvantages large quantities dangerous sludge that is unrecoverable repelled. Physical separation used isolate petroleum and, some cases, recycled with number great disadvantage demand energy blockages clogging tools equipment this process. Third-party refinement meet objective reuse using nano-filtration, reverse osmosis, oxidation. Adsorption an emergency technology applied minerals excellent materials low-cost adsorbents. By combining adsorption process one lower production, cost also reduced.

Current and emerging trends in bioremediation of petrochemical waste: A review

Critical Reviews in Environmental Science and Technology, Journal Year: 2017, Volume and Issue: 47(3), P. 155 - 201

Published: Feb. 1, 2017

Various industries release harmful petrochemical contaminants into the environment. To treat these at source, different physical, chemical, and biological methods have been proposed applied worldwide. However, physical chemical their own advantages limitations; in this review, we majorly focused on biodegradation of wastes. First, a background study literature available field is presented. Second review toxic effects waste various processes, followed by elaborate processes for degradation. Further, aspects bioremediation, such as modes, factors, limitations, future perspectives are critically reviewed It was found that most studies performed bioremediation employed bacteria degradation purpose. Some also made use algae, fungi, yeast, genetically modified organisms, biosurfactants, or consortium microbes. Moreover, still limited scale due to certain which elaborated article. Overall, strongly believe with capturing attention environmentalists worldwide, there prevailing need up from lab land level applications adaptations.

Titanium Dioxide-Based Photocatalysts for Degradation of Emerging Contaminants including Pharmaceutical Pollutants

Applied Sciences, Journal Year: 2021, Volume and Issue: 11(18), P. 8674 - 8674

Published: Sept. 17, 2021

Contamination of the environment has been a growing problem in recent years. Due to rapid growth human population, expansion cities, along with development industry, more and dangerous chemicals end up environment, especially soil water. For most part, it is not possible effectively remove through traditional remediation techniques, because those used treatment plants are specifically designed for this purpose. Therefore, new approaches water great demand. Many efforts have focused on applications photocatalysis chemical pollutants including drugs. Titanium(IV) oxide nanoparticles particularly considered as potential photocatalysts due their favorable properties. In article, we present emerging contaminants drugs discuss use based titanium(IV) degradation. A wide selection materials, starting from bare TiO2, via its hybrid composite discussed carbonaceous materials or connections macrocyclic structures. Examples photodegradation experiments TiO2-based performed various active pharmaceutical ingredients also included.
