The primary purpose of this study is to investigate boron removal from synthetic hydraulic fracturing wastewater by membrane processes. The effects of pressure, pH, feed concentration, and polyol concentration on boron removal were determined using a cross-flow, flat-sheet membrane test unit. The...

The widespread use of alternative water sources in Kelantan encourages the development of cost-effective methods for the purification of water. A simple and straightforward adsorption process using a nanomagnetic adsorption composite (NMAC) was introduced in this study as a new adsorbent for the...

Industrial wastes represent a huge issue for the environment and precious materials for microbial growth. Utilizing these wastes in different fermentation process decrease the costs of production, materials, energy, and represent an eco-friendly way of waste recycling. Aspergillus niger (ASU49) is...

Synthesis of Ni/Al-LDH prepared into Ni/Al-Hc composites using hydrochar from rambutan peel (Hc) and applied as a congo red adsorbent and analyzed based on adsorption selectivity, kinetics, isotherms, adsorption thermodynamics and recycling. The success of Ni/Al-Hc composite preparation was proven...

This essay deals with the prospects of supplying humanity with energy in the twenty-first century. The gradual replacement of fossil fuels by green electricity, hydrogen and biofuels is examined in the context of deteriorating climate change and the ongoing depletion of fossil fuels. The production...

In the present work meteorological data, concerning temperature and precipitation in a mountainous Bulgarian fir (Abies borisii-regis Mattf.) forest, was analyzed in order to find trends for the period 1973-2019. The results showed that temperature values on annual and seasonal base, especially in...

The packed bed column study investigated the removal of toxic metal ions (Cr, Pb & Zn) using rice husk coated with iron oxide nanoparticles as an adsorbent material. The chemical fusion process prepared the nanomaterial adsorbent, and iron oxide capping provides stability to the prepared nano...

This study focused on removing methylene blue (MB) from aqueous solutions using microalga Scenedesmus regularis as a biosorbent. The biomass was characterized by Fourier transform infrared spectroscopy (FT-IR) and field emission scanning electron microscopy (FE-SEM). The difference in thermal...

Adsorption is an effective and widely technique used for separation many pollutants from wastewater. Pollution of water with color material such as dyes is of environmental concern due to their toxicity and cause carcinogenic effects on human and aquatic life. These dyes are presented into the water...

In this experiment, in the background of the plateau environment, the effects of ultraviolet irradiation on the microbial community structure, metabolic pathways and nitrogen metabolism function genes of sewage were studied at 0 (control group), 5, 10, 30, and 180 min. The results showed that the...
