Special Issue "Wastewater Treatment Processes"
Deadline for manuscript submissions: 31 March 2019

Cheap and plentiful, water was for centuries a manufacturing tool that industry took for granted. However, population growth, globalization, and climate change are shepherding in a new water-constrained era. The food-chain pyramid may receive contaminants of either surface water or ground water around industrial and residential communities (e.g., metals, pesticides, pharmaceuticals, etc.) through man’s activities and on top of the pyramid, man (perhaps) receives pre-concentrated toxicity. A common example constitutes Bangladesh, where millions of people consumed drinking water with arsenic concentrations—exceeding the guideline values of WHO. Good, clean water just cannot be replaced—and it is becoming harder to come by. Typical processes that are investigated and applied to wastewater treatment can be the following: Biological, adsorption, flocculation, oxidation, membranes, filtration, and so on, including the nanotechnological. This Special Issue on “Wastewater Treatment Processes” seeks high-quality works and topics (not only those) focusing on the latest novel wastewater processes, including biological, adsorption, flocculation, oxidation, membranes, filtration, etc.

Title: Effect of Primary Variables on a Confined Plunging Liquid Jet Reactor

Abstract: The effects of the jet velocity, nozzle diameter, jet length and confining downcomer diameter and nozzle contraction angle on the gas/air entrainment rate, Qa, were investigated for a vertical confined plunging liquid jet reactor (CPLJR) as an alternative aeration process that is of interest in Kuwait and can be used in various applications, such as in wastewater treatment as an aerobic activated sludge process, fermentation and gas-liquid reactions. A CPLJR provides efficient oxygen transfer at a low cost. Various downcomer diameters (45–145 mm), jet lengths (200–500 mm), nozzle diameters (3.5–15 mm) and contraction angles (20–80°) were investigated. The air entrainment results showed that these were the primary parameters for the measured air entrainment rate in confined systems. The highest gas entrainment rates were achieved when the ratio of the downcomer diameter to the nozzle diameter was greater than approximately 5, as long as the liquid superficial velocity was sufficient to carry bubbles downward.

Title: SPSS Statistics Analysis of Circulating Water Quality Parameters under Variable-Frequency Vertical Electromagnetic Fields
Authors: Jianguo Wang and Fang He
Abstract: There is currently no unified electromagnetic anti-fouling mechanism. Most research focuses on the effect of structure parameters and water quality parameters on electromagnetic fields. The research on variations in water quality parameters under the influence of electromagnetic fields has not been reported. An experiment for variable-frequency vertical electromagnetic fields is proposed in this study. The relationship between conductivity, pH value, dissolved oxygen, turbidity, fouling resistance and magnetic acting time is carefully analyzed using SPSS statistical methods. Results show that magnetic acting time has a greater impact on conductivity than pH value and dissolved oxygen. Conductivity is used as an adaptive feedback control parameter for the optimum state of anti-fouling. The fouling resistance on the heat-exchanging surface of the magnetic experiment is smaller than that of the contrast experiment. Electromagnetic fields are applicable for mitigation of fouling. It is confirmed that physical water treatment is an effective and environment-friendly method to eliminate heat exchanger fouling. This research provides basic preparation for an
electromagnetic-adaptive closed-loop water treatmentdevice.
