INVESTIGATION OF FUNCTIONAL DIVERSITY AND ACTIVATED SLUDGE CONDITION USING BIOLOG® SYSTEM

Activated sludge method dominates among the currently used biological wastewater treatment systems. The dynamic development of this technology implies need for research, most of which are carried out in laboratory conditions. Biolog system seems to be an effective tool that allows a quick assessment of microbial activity of activated sludge. The aim of this study was to verify Biolog® EcoPlates’ usage for comparing the functional and metabolic diversity of activated and excess sludge

A SIMPLIFIED MODEL STRUCTURE FOR AN ACTIVATED SLUDGE SYSTEM

Activated sludge system is the essential technology in use for municipal wastewater treatment plant. The system design for pollutants removal, safety analysis and experimentation relied upon an effective, straightforward and reliable model. However, most of the available models are too complex to use for control purposes either practically or via simulation. Therefore, vehement need for a simplistic and efficient model could not be avoided. This paper presents a simplified model structure for

USE OF BIOLOGICAL METHODS FOR REMOVAL OF H2S FROM BIOGAS IN WASTEWATER TREATMENT PLANTS – A REVIEW

generate heat and electricity, biogas should be cleaned. H2S is a colourless, flammable, malodorous and toxic gas. The main issues due to the high concentrations of H2 S in biogas are its corrosive action, which damages engines and the production of sulfur oxides (SOx ) due to H2 S combustion. The best ways to remove H2 S from biogas are the biological methods with the use of biofilters, biotrickling filters, bioscrubbers and using of activated sludge.

Improving total nitrogen removal using a neural network ammonia-based aeration control in activated sludge process

requirements and is also economical. Studies have shown that the energy consumption in the biological system such as activated sludge process, biological trickling filters, and membrane bioreactors can be curbed through good control of the aeration system. The issue of energy consumption has been investigated by various researchers and the findings suggest that the aeration section which is needed in the WWTP to detract nitrogen and natural or inorganic carbon in the biological process, contributes to 50

RESEARCH ON THE CULTIVATION OF NITRIFYING BACTERIA AND POSSIBILITY OF THE BIOMASS STORAGE

The efficiency of nitrification has a great influence on the effect of removing nitrogen from wastewater. Problems with the process are associated with reducing the age of activated sludge, lower temperatures of wastewater in aeration chambers, rapid changes in the amount and composition of wastewater containing toxic substances or inhibiting the oxidation of ammonia nitrogen. The research concerned the possibility of cultivation and storage of the nitrifying bacteria biomass, which could be

PREDICTION OF SEWAGE QUALITY BASED ON FUSION OF BPNETWORKS

Sewage treatment system is a complicated nonlinear system with multi-variables, chemical reaction, biological process and altered loads, hard to describe mathematically. Thus prediction of the effluent quality parameters of sewage treatment plant has being a challenge. In this paper we adopt fusion of two BP networks to predict sewage quality parameters with a popular process Cyclic Activated Sludge System (CASS). We take use of SVM (support vector machine) to classify the input data into two

to about 100%) and less sensitive to pollutants (such as toxic substances) that determine the inapplicability of processes based on activated sludge. As a result, they can be applied practically in all process environments. The present trends in water and wastewater technology are directed towards membrane techniques and, in a lesser part, ion exchange, due to the good knowledge and appropriate level of development of these technologies. However, the most important disadvantages are non

ANALYSIS OF THE POSSIBLE APPLICATION OF DEAMMONIFICATION TECHNOLOGY IN THE MUNICIPAL WASTEWATER TREATMENT PLANT IN ZABRZE

deammonification (SD) application in reject water treatment is illustrated in Figure 2. Figure 2. Typical side stream deammonification (SD) application in a WWTP with activated sludge process [13]. SD: sidestream deammonification; RAS: return activated sludge; WAS: waste activated sludge Normally, reject water is led to the WWTP mainstream without separate treatment. Deammonification in sidestream can remove up to 90% of the internal nitrogen load in reject water. This way, nitrogen removal process in the
