Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...

Abstract The wastewater from industry is contaminated with dyes, which should be removed in order to prevent environmental damage. This paper presents a method for removing methylene blue an aqueous solution using fixed-bed adsorption process onto sawdust. In the article, of continuous measurement concentration sorption on sawdust was used. results were compared obtained by standard periodic te...

As one of the artificial recharge technologies, soil–aquifer treatment (SAT) system is used for removal nitrogen pollution from aquaculture wastewater. An adsorption-enhanced SAT was designed to reduce level below threshold stipulated by standards. Adsorption kinetics experiments were measure adsorption capacity zeolite and activated carbon ammonia nitrogen. Both adsorbents can be well describe...

The development of a comprehensive approach to preventing the pollution natural objects is necessary due high requirements environmental legislation for discharge industrial wastewater. Adsorbents are used in various industries extract heavy metals from In this study possibility using saponite clay as raw material production sorbent extraction copper ions Cu2+ wastewater considered, recipe and ...

Abstract Numerous harmful characteristics of wastewater containing pyridine chemical have a significant negative impact on human health. Therefore, it is preferred to remove from effluent. The derivatives are 2- and 4-picoline. In this work, an adsorption technique was used 4-picoline the Wastewater treated using natural adsorbent baggage fly ash (BFA). rate 82% reported at pH 6.22, BFA dosage ...

BACKGROUND Discharging the oily wastewater in the environment causes serious problems, because of the oil compounds and organic materials presence. Applying biological methods using the lipase enzyme producer microorganisms can be an appropriate choice for treatment of these wastewaters. The aim of this study is to treat those oil wastewaters having high concentration of oil by applying lipase ...

Advanced wastewater treatment using membranes are popular environmental system processes since they allow reuse and recycling. However, fouling is a key limiting factor and so proprietary systems such as Avanti's RPU-185 Flexidisks membrane bioreactor (MBR) use novel rotating membranes to assist in ameliorating it. In earlier research, this rotating process was studied by creating a simulation ...

It is assumed that microbial communities involved in the biological treatment of different wastewaters having a different chemical composition harbor different microbial populations which are specifically adapted to the environmental stresses encountered in these systems. Yet, little is known about the composition of these microbial communities. Therefore, the aim of this study was to assess th...
