The current study investigated the mathematical prediction model for the inactivation of antibiotic-resistant bacteria (B. subtilis, S. aureus, and E. coli) in kitchen wastewater by bimetallic bionanoparticles (Zn/Cu NPs) using gene expression programming (GEP). The interaction between Zn/Cu NP concentration, time, pH, initial cell concentration, a...

In this article, the nickel (Ni²⁺) ions removal from the wastewater is reviewed. Adsorption is widely used to remove Ni²⁺ ions from waters and wastewaters. The usage of biomass is becoming more common for Ni²⁺ ions removal, while the commercial activated carbon from different agriculture wastes is preferred as an adsorbent for Ni²⁺ ion removal. The...

The aim of the study was to investigate the efficiency of iron chloride in term of color, chemical oxygen demand (COD), TSS and turbidity removal of dye waste. Response surface methodology (RSM) using central composite design (CCD) was employed to analyze and investigate the effects of the independent factors on color, COD, turbidity, and TSS remov...

Millions of litters of multifarious wastewater are directly disposed into the environment annually to reduce the processing costs leading to eutrophication and destroying the clean water sources. The bioelectrochemical systems (BESs) have recently received significant attention from researchers due to their ability to convert waste into energy and...

The current review highlighted the quantitative microbiological risk assessment of Vibrio parahaemolyticus in Prawn farm wastewaters (PFWWs) and the applicability of nanoparticles for eliminating antibiotic-resistant bacteria (ARB). The high availability of the antibiotics in the environment and their transmission into human through the food-chain...

Abstract: The promising feature of the fungi from the marine environment as a source for anticancer agents belongs to the fungal ability to produce several compounds and enzymes which contribute effectively against the cancer cells growth. L-asparaginase acts by degrading the asparagine which is the main substance of cancer cells. Moreover, the com...

Textile industry is one of the most environmental unfriendly industrial processes due to the massive generation of colored wastewater contaminated with dyes and other chemical auxiliaries. These contaminants are known to have undesirable consequences to ecosystem. The present study investigated the best operating parameters for the removal of congo...

The present research aimed to enhance the pharmaceutically active compounds’ (PhACs’) productivity from Streptomyces SUK 25 in submerged fermentation using response surface methodology (RSM) as a tool for optimization. Besides, the characteristics and mechanism of PhACs against methicillin-resistant Staphylococcus aureus were determined. Further, t...

The aim of the current study was to optimize the efficiency of polyaluminium chloride (PAC) for reducing colour from the ink effluent. The optimization process was conducted based on pH, coagulant dose, mixing time and mixing speed. The phytotoxicity in treated dye effluent using green bean seeds to use on seed germination test. The optimal reducti...

The study aimed to investigate potential of zinc oxide nanoparticles (ZnO NPs) synthesized by Corriandrum sativum leaf extract as nutrient source for Vigna radiate seeds in relation to seedling growth and germination Vigna radiate seeds. The ZnO NPs were prepared at 100°C [[ZnO [A]] and calcined at 550°C [[ZnO [B]]. The synthesized ZnO NPs was char...

This study aims to investigate the potential of green zinc oxide nanoparticles (ZnO NPs) in reusability performance for photocatalysis of bathroom greywater. It was found that ZnO NPs photocatalytic treatment of real bathroom greywater (RBGW) effluent reduces both the COD and BOD5 concentrations by 72.01, 62.75 and 57.79% (COD) and 70.18, 60.32 and...

Azo dyes including C. I. Basic Brown 16 (BB16) are one of the coloured organic compounds that have adverse effects on human health and the environment. The current work aims to optimise the adsorption of C.I BB16 in aqueous solution using durian (Durio zibethinus murray) shell as a low-cost green adsorbent. Durian shell was characterised by Fourier...

The aim of the current study was to optimize the efficiency of polyaluminium chloride (PAC) for reducing color from the ink effluent. The optimization process was conducted based pH, coagulant dose, mixing time and mixing speed. The phytotoxicity in treated dye effluent using green bean seeds to use on seed germination test. The optimal reduction e...

The presence of SARS-CoV-2 in sewage and water resources has been used as an indication for the possible occurrence of the virus among communities and for its potential of transmission among humans through the surrounding environment or water resources. In order to reduce the transmission of SARS-CoV-2, contaminated surfaces should be disinfected f...

The management practice of the fresh market wastes (wastewater and solid waste) plays an important role in the presence or absence of the adverse effect on the environment which received the disposed of wastes. The management process included the collection, segregation, transportation, treatment, and final disposal of the wastes into the environme...

The increase of water demand and wastewater generation is among the 1 global concerns in the world. The less effective management of water sources leads to 2 serious consequences, the direct disposal of untreated wastewater is associated with 3 the environmental pollution, elimination of aquatic life and the spread of deadly 4 epidemics.
