The previous TurboScrubber unit absorbed H2S to 99.997% efficiency into NaOH to handle Chlorine & Chlorine Di- oxide emissions from process ...
Intermolecular contact, the formation of local high temperature and pressure, and the simultaneous generation of free radicals and excited reactive oxygen species, not only rapid oxidation of sulfides. Improves oxidation of oxidants, improves reaction selectivity, significantly shortens oxidation reaction time, and can also ...

Ozone (O3), hydrogen peroxide (H2O2), and hydroxyl radicals are strong oxidizing agents capable of oxidizing a wide range of organics, COD and TOC. ...
This mixed gas is then fed into the NH3 oxidation reactor. The filtering of the mixed gas is therefore of critical importance as any particulates carried downstream could result in expensive failure of in the reactor. Before the gas is fed into the reactor, it is passed through the mixed gas filter vessel, into which ...
AquaCritox and Hydrothermal Oxidation AquaCritox is a hydrothermal oxidation process that involves the use of pressure, temperature and oxygen to effect partial or complete oxidation of the oxidisable components present in a sludge or contaminated water based waste stream. ...
Sulfur-oxidizing autotrophic denitrification (SO-AD) was investigated in a laboratory-scale moving-bed biofilm reactor (MBBR) at a sewage temperature of 22 °C. ...
PROJECT DETAILS LOCATION Tivoli, Italy CUSTOMER Consorzio Cartiere di Tivoli SRL SOLUTION Wastewater Treatment, Waste-to-Energy TECHNOLOGIES External Forced Circulation (EFC) Reactor, Oxidation, and Clarification System Sustainability is a primary goal driving businesses worldwide. ...
The down-flow hanging sponge (DHS) reactor was used for continuous As removal treatment of As-contaminated water. The treatment scheme was: (1) As(III) in contaminated water is oxidized by arsenite-oxidizing bacteria fixed in the sponges in the reactor; (2) Fe(II) naturally existing in the water is oxidized ...
Current results demonstrate the potential feasibility of mainstream deammonification, and also highlight the unique performance characteristics and challenges associated with biofilm and suspended growth deammonification reactors. Efficient retention of anammox biomass was a key advantage of the biofilm reactor, but nitrite oxidizing bacteria ...
A boron doped diamond (BDD) electrode was employed in an electrochemical reactor to oxidize the phenolic content of Jordanian olive mill wastewater. ...
The primary goal of this study is to investigate ammonia removal, abundance of nitrifying bacteria and microbial community structures in a laboratory-scale integrated fixed film activated sludge (IFAS) reactor. The results of Illumina MiSeq sequencing based on 16S rRNA genes showed Proteobacteria and Bacteroidetes were the dominant phyla in both biofilm and suspended sludge ...
As a failsafe, Anguil installed an induced draft fan on the catalytic oxidation system. By placing the fan on the discharge side of the oxidizer rather than placing it on the inlet side, the system was under a continuous negative pressure. This meant that any leakage associated with the oxidation system would be released back into the system, ...
Immobilized granular sludge is of key importance for highly effective operation of partial nitrification and anaerobic ammonium oxidation (PN-Anammox) reactors. An observation and analysis on the composition of immobilized granular sludge in each reactor was conducted by using scanning electron microscopy (SEM) and fluorescence in situ ...
Various treatment scenarios were attempted and focused on studying the effect of pre-catalytic oxidation process on the performance of up-flow anaerobic sludge blanket (UASB), UASB/down-flow hanging sponge (DHS) and DHS system. The results obtained indicated that pre-catalytic oxidation process improved the CODt removal efficiency in the UASB ...
A detailed investigation of photocatalytic degradation of m-cresol purple (mCP) dye has been carried out in aqueous heterogeneous medium containing zinc oxide (ZnO) as the photocatalyst in a batch reactor. The effects of some parameters such as amount of photocatalyst, dye concentration, initial pH of solution, ethanol concentration and temperature were ...
In this study, a laboratory-scale sequencing biofilm batch reactor (SBBR) was employed to explore a fast start-up of completely autotrophic nitrogen removal over nitrite (CANON) process. Partial nitrification was achieved by controlling free ammonia concentration and operating at above 30 °C; then the reactor was immediately operated with alternating periods ...
The nitrification process was efficient in a moving bed biofilm reactor with maximal rates of 930 mg N L−1 d−1. Rates decreased to 120 mg N L−1 d−1 after switching to more concentrated urine. ...
A continuous upflow biofilm reactor packed with ceramsite was constructed for nitrate removal under an anaerobic atmosphere without an organic carbon source. Denitrifying bacteria, Pseudomonas sp. W1, Pseudomonas sp. W2 and Microbacterium sp. W5, were added to the bioreactor as inocula. Nitrate concentration, nitrite accumulation and nitrogen removal efficiency in the effluent were investigated ...
Bacterial community composition considerably changed along the reactor and over the operational period. The dominant phyla detected were Proteobacteria, Verrucomicrobia, and Planctomycetes. ...
The concentrations of PFCs with long chains were much lower than those PFCs with short chains (≤C8). An electrochemical oxidation reactor was employed for advanced treatment of PFCs in WWTP effluents using stainless steel plates as anode and cathode electrodes. ...
