Oil sludge treatment plant
In the process of oil development, storage, transportation, and use, due to uncontrollable factors in the operation process, crude oil may leak out and combine with soil and impurities to produce oil sludge. Oil sludge contains a large amount of oil, water, inorganic materials, radioactive elements, dioxins, pathogenic bacteria and other toxic and harmful substances that are difficult to degrade, ...

A neural network approach for on-line fault detection of nitrogen sensors in alternated active sludge treatment plants
In this paper, an effective strategy for fault detection of nitrogen sensors in alternated active sludge treatment plants is proposed and tested on a simulated set-up. It is based on two predictive neural networks, which are trained using a historical set of data collected during fault-free operation of a wastewater treatment plant and their ability to predict reduced (ammonium) and oxidized ...

Full-scale control of Mycolata foam by FEX-120 addition
Foaming incidents in activated sludge treatment plants are a worldwide problem and occur on a regular basis in both municipal and industrial activated sludge treatment plants. Foaming is most often caused by excessive growth of filamentous bacteria, especially the gram-positive ones affiliated within the Actinobacteria, e.g. the branched Mycolata or CandidatusMicrothrix parvicella. Previous ...

Enhanced dewaterability of sewage sludge with zero-valent iron-activated persulfate oxidation system
The potential benefits of zero-valent iron-activated persulfate (Na2S2O8) oxidation in enhanced dewaterability of sludge, along with the associated mechanisms were investigated in this study. The sludge dewaterability was evaluated in terms of specific resistance to filtration (SRF) and water content. Based on these indexes, it was observed that ZVI-S2O82 oxidation effectively improved sludge ...

How To Pick The Right Sewage Sludge Treatment Plant
If you have an enterprise that may be processing every one of the raw sewage in a city, you need to ensure that it is up-to-date. The most recent technology may be used to condition that sewage and transformed into something usable. It is easy to take raw sewage, and utilizing an operation called pyrolysis, convert this into biofuels. Some of this can be liquid, whereas others will likely be ...

The Reasons Companies Purchase Oil Sludge Treatment Plants
Oil sludge is a unique material that is made up of water, solid particulate materials, and residue levels of oil. This sludge can be reused if properly processed while using right machinery. There is generally a solvent extraction machine used, produced from the newest technology. It can do removing chemicals, oil, water, and will do all this using a process called pyrolysis. Many of the latest ...

Polyhydroxyalkanoates (PHA) biosynthesis from kraft mill wastewaters: biomass origin and C:N relationship influence
The goal of this study is to evaluate the feasibility of PHA biosynthesis from kraft mill effluent using the batch system evaluating the biomass origin and C:N relationship influence. To evaluate feasibility, batch assays were carried out. Also, two levels of the BOD5:N:P relationship (100:5:1 and 100:1:0.2) and three different sludge origins were considered. Inocula were obtained from activated ...

Huber sludge treatment plant on the black sea coast - Case study
The Bulgarian Black Sea Coast along the city of Varna with 300,000 residents is an important economic factor, especially due to its touristic potential. The European Union decided in 2002 to give aid money for the protection of the Black Sea, in particular for upgrading and building new local sewage treatment plants. The capacity of the sewage treatment plant at Varna could therefore be expanded ...

Nutrient transfer by runoff from sewage sludge amended soil under simulated rainfall
Wastewater sludges are used in agriculture as soil amendment and fertilizer, with regard to their organic matter and nutrient content. However, availability of nitrogen and phosphorus from sludge-amended soils and their transfer in runoff may lead to eutrophication of downstream surface water. The aim of this study is to establish and compare the effect of two different sludges on these ...

A combined process of non-thermal plasma with sludge stabilization for the simultaneous reduction of odor and organic waste
Odor emissions and sludge disposals have become most challenging issues in many sludge treatment plants, and separate chemical oxidation processes have been commonly employed for these problems. It is, therefore, necessary to develop a combined process that simultaneously reduces the odor emissions and the amount of waste sludge. In this study, a non-thermal plasma reactor using a dielectric ...
