The novel coronavirus (COVID-19) is sweeping the world starting in 2019. According to analysis based on big data technology, wastewater generated by hospitals hosting SARS-CoV-2 infected patients complex origin and composition, contains a large number of pathogenic microorganisms drugs, etc. Without effective treatment, it will become an important pathway for spread epidemic source environmenta...

A study has been conducted to investigate the effect of loading rates on membrane fouling in a moving bed biofilm membrane reactor process for municipal wastewater treatment, especially analysing the fate of submicron colloidal particles and their influence on membrane fouling. Two operating conditions defined as low and high organic loading rates were tested where the development and fate of t...

This study investigated the removal of micropollutants using polyurethane sponge as attached-growth carrier. Batch experiments demonstrated that micropollutants could adsorb to non-acclimatized sponge cubes to varying extents. Acclimatized sponge showed significantly enhanced removal of some less hydrophobic compounds (log D<2.5), such as ibuprofen, acetaminophen, naproxen, and estriol, as comp...

Nowadays formaldehyde is used as raw material in many industries. It has also disinfection applications in some public places. Due to its toxicity for microorganisms, chemical or anaerobic biological methods are applied for treating wastewater containing formaldehyde.In this research, formaldehyde removal efficiencies of aerobic biological treatment systems including moving bed biofilm (MMBR) a...

Dairy industry wastewater is rich in organic content, presenting a high biodegradability, and therefore biological treatments are widely employed. This study aimed to evaluate biosolids production three systems: activated sludge (AS), movingbed biofilm reactor (MBBR), sequencingbatch (SBMBBR). Simulated dairy was used at different load rates (OLRs): 1.22, 2.87, 5.44 gCOD L−1d−1. Besides product...

background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...
