The effluent quality of a wastewater treatment plant (WWTP) in Hebei Province met the Class I-A standard of "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants"(GB 18918-2002) (COD≤50 mg/L, TN≤15 mg/L, TP≤0.5 mg/L, NH3-N≤8 mg/L). However, under the guidance of energy...

People are prompted to complain about air pollution by offensive odours. They can produce psychological consequences, such as nausea, headaches, lack of appetite, breathing difficulties, and various adverse reactions in some circumstances. Among various industries, the dairy industry emits the most...

The electrolytic approach was combined with radiolysis employing gamma radiation as an enhanced oxidation process to study the decomposition of 1-(4-Hydroxy-3-Methoxyphenyl) ethenone (Apocynin (ACN)). For Apocynin breakdown from effluent water, a photo-catalytic membrane reactor (PMR) was utilized...

This study aimed to evaluate the performance of microscreen drum filter and ultrafiltration (UF) as a ‎tertiary treatment to improve the secondary effluent quality. Additionally, hydraulic loading of ‎drum filter and membrane flux of UF were changed. On average, the use of drum filter and UF...

Slaughterhouse wastewaters are characterized by a high organic content, mainly composed of proteins and fats. Therefore, these wastewaters should be treated efficiently prior to discharge into receiving bodies to avoid severe environmental pollution. This work aimed to characterize slaughterhouse...

Sequencing batch reactor (SBR) is a time-oriented wastewater treatment (WWT) system in a single reactor with flow and energy input according to the predetermined operational cycle time. The treatment efficiency of SBR varies with the duration of the cycle time, which affects the reactor size and...
