Abstract: Ultrafiltration (UF) is one of the best options for both one-stage and as part of multi-stage water and wastewater purification. This review summarises the known facts about the fouling processes and cleaning procedures and details of the most successful physical and chemical cleaning combinations. The optimum cleaning is closely linked to the nature of the fouling. Precise knowledge of both the fouling type (organic, inorganic, or biological) and the fouling mechanism (gel formation, adsorption, deposition, pore blockage, or cake formation) is the key to success in UF membrane cleaning.

Abstract: In recent years, adsorption has displayed promising and effective results as a treatment technology for water and wastewater by industries. In the process, a number of adsorbents have been synthesized and applied for the treatment of pollutants such as metals, dyes, pharmaceutical products in solutions. However, for adsorption to be unconditionally adopted by industries, a few obstacles such as high capital cost, difficult segregation of adsorbent from solution, and complex synthesis processes need to be addressed. The removal of suspend adsorbents in wastewater from a continuous flow system is a challenge which if addressed properly would enable us to recover the spent adsorbent efficiently. The spent adsorbents can then be regenerated and used again by the industries thereby leading to reduced capital investment. Therefore, studies have been carried out aiming at the incorporation of magnetism in such adsorbents to aid their removal from wastewater. This review aims to comprehensively list and discuss adsorbents which exhibit magnetic properties and their adsorption behaviour under diverse conditions. The literature survey presented in this paper renders evidence to the good potential of magnetic adsorbents to remove various pollutants from wastewater. However, the practical utility of such adsorbents needs to be explored before they can be commercially applied.

Abstract: Presence of toxic and recalcitrant heavy metal ions in industrial effluents is a major environmental concern. These fatal metal ions are not only hazardous in exceeding concentrations but due to the property of biomagnification it is urgent to look for the plausible solutions. This review article is an attempt to gather the research findings attempted in yester years for the removal of such metals from aqueous solutions by using waste materials from industries, such as blast furnace sludge, slag and flue dust, fly ash, black liquor lignin, and red mud. Studies have been complied keeping various efficiency influencing parameters such as optimum dose, contact time, initial concentration of metal ions, and many more in consideration. This article also tries to summarize the various problems and shortcoming of the work carried so far and attempts to explore the feasible suggestions.

Abstract: This review provides insight into the implementation of membrane technology in the petroleum industry for treating produced water that is generated from conventional oilfields in upstream and downstream processes. The ever-evolving and increasingly stringent regulatory standards for discharging produced water pose colossal environmental and economic implications because the bulk of this produced water is disposed into the environment. Thus, a review of the implementation of membrane technology for produced water treatment could contribute to the knowledge required for the increased introduction of scaled-up membrane technology in the petroleum industry. This review encompasses the capabilities and performance optimization possibilities of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis membranes. The level of applications that these membrane technologies might attain within the petroleum industry were determined, and these implementations were correlated with the purpose, performance efficiency, treatment system configurations, necessary pretreatment procedures, quality of treated produced water, fouling occurrence and control, foulants, cleaning procedures, raw produced water content, potential challenges with corresponding applied solutions, and economic factors. This review also maps current and future trends and provides a perspective on the outlook for advances in novel membrane applications for produced water treatment.

Abstract: The present study shows the applicability of carbon nanoparticles made from vine wood as an inexpensive adsorbent for the removal of Amoxicillin, Cephalexin, Tetracycline and Penicillin G from aqueous solutions. The activation of carbon nanoparticles was studied by aqueous solutions of NaOH, KOH, ZnCl 2 , NaCl and HNO 3 . The removal efficiency ( R %) of pollutants showed that NaOH can be used as an efficient, low-cost and environmentally friendly activator ( R % = 74–88). Infrared spectroscopy, XRD pattern, BET and BJH methods and scanning electron microscope (SEM) images were used to characterize the prepared carbon. The area and pore volume of activated carbon were obtained as 13.397 m 2 /g and 54.79 cm 3 /g, respectively. The SEM images showed a high porosity for activated carbon. Removal of antibiotics from aqueous samples was carried out using a modular method. The optimized parameters of pH 2, an amount of adsorbent of 0.4 g/L, a concentration of antibiotic solution of 20 mg L −1 , a contact time of 8 h and a temperature of 45 °C were obtained in a modular way. Kinetic studies confirmed that the adsorption followed second-order reaction kinetics. Thermodynamic studies revealed that the process was spontaneous and endothermic. The reusability of sorbent was achieved by using of NaOH (5 w/w%) solution and recovery time of 4 h.
