The aim of the work was to purify model textile wastewater (MTW) using a two-stage membrane filtration process comprising nanofiltration (NF) and reverse osmosis (RO). For this purpose, TFC-SR3 (KOCH) AG (GE Osmonics) were used. Each contained selected surfactant. greatest decrease in flux initial phase occurred for detergents based on fatty-acid condensation products. An evident performance observed with polysiloxane-based surfactants. No fouling effect high values containing nonionic...

The influence of various factors on the removal efficiency selected pharmaceuticals by membrane filtration was investigated. Several commercial polymer membranes were used for nanofiltration (NF) from manufacturers. studies conducted ibuprofen (IBF), amoxicillin (AMX), diclofenac (DCF), tetracycline (TRC), salicylic acid (SA) and acetylsalicylic (ASA). structure properties tested compounds retention coefficient rate pH parameters also checked. influencing filtrate flux analysed. An extensive...

The aim of the research was to improve treatment technology wastewater from dyehouse using ozonation and biological processes. various combinations processes were examined. Ozonation performed in two reactors working volume 1 dm3 (stirred cell) 20 (bubble column), while biodegradation conducted sequence batch (SBR 1.5 dm3) horizontal continuous flow bioreactor (HCFB, 12 dm3). highest removal organic carbon content (COD–72%, TOC–78%) obtained 3-steps experiment: plus biodegradation, however,...

The aim of this study was to investigate the effect hydrogen peroxide on UVC photolysis diclofenac (DCF) in aqueous solution. experimental results confirmed very high effectivity direct diclofenac. Moreover, it found that H 2 O /UV only slightly improved photodegradation; however, addition into reaction system affected mechanism DCF decomposition. Kinetics with ⋅ OH radicals UV/H process determined. For both processes, namely, and , an in-depth analysis focused formation phototransformation...

The possibility of removing tetracycline (TRC) from water in an integrated advanced oxidation and membrane filtration process was investigated. Ozonation UV/H2O2 photooxidation were applied for the destruction TRC. Six products (OPs) retaining structural core TRC have been identified. One new product, not reported so far literature, identified—ethyl 4-ethoxybenzoate. All identified OPs effectively retained on nanofiltration process. However, chemical oxygen demand (COD) measurements...

Application of Fenton's Reagent in the Textile Wastewater Treatment Under Industrial Conditions reactive dyes is very popular textile industry as these dyestuffs are characterized by good fastness properties. Constapel et al 2009 estimated production this type for over 140,000 Mg/year. The mostly (50%) employed coloration cellulosic fibers, however they can also be applied on wool and nylon. Unfortunately, possess a low degree fixation (50÷90%), since functional groups bond to water,...

The aim of the study was to determine effect acetic acid on pollutant decomposition in textile wastewater subjected Fenton process.To clearly assess treatment efficiency for subsequent types wastewater, COD reduction calculated mixtures a given type with acid.The values were compared obtained experiments oxidation wastewater-acetic process.The presence seriously deteriorated conditions which affected processes.

C.I. Reactive Black 5 (RB5) is the most commonly used dye in textile industry. Ozone a strong oxidan that can decompose many barely degradable pollutants, including dyes. Although there are literature reports devoted to treatment of wastewater and solutions by ozone, ozonation mechanism modeling kinetics still not well covered. In this work kinetic model process RB5 decolourisation ozone has been proposed validated on basis experimental data. The experiments were carried out liquid-liquid...

The research covered the process of nanofiltration low molecular weight organic compounds in aqueous solution. article presents results experiments on membrane filtration containing amino groups aromatic ring and comparing them with for without groups. was carried out several commercial polymer membranes: HL, TS40, TS80, DL from various manufacturers. It has been shown that presence group its position relation to carboxyl molecule affects retention process. also included oxidation products...

Extremely high volumes of salty wastewater are produced by textile manufacturers daily. Therefore, brine recycling from the should be regarded as a crucial issue within industry. Ozonation was used in this two-part study purification method for industrial polluted low-molecular-weight salts (LMWS). Part 1 revealed accumulation ozonation by-products multi-recycling system. The objective 2 scaling-up process and investigation occurrence by-products. It found that works well an alkaline...

The present studies covered investigations of advanced oxidation detergents in industrial wastewater with the use ozone, hydrogen peroxide, UV and ionizing radiation separately combinations: O3+UV, UV+H2O2, H2O2+O3, O3+H2O2+UV, O3+ flow systems taking into account specific features subsequent versions. aim these was to results detergent decomposition applied versions also compared stationary systems. processes were carried out high efficiency all tested. best achieved samples exposed...

The aim of the work was to determine influence salicylic acid (SA) oxidation products on effectiveness their further removal in membrane filtration process. Two commercial polyamide-based polymer membranes, HL (GE Osmonics) and TS80 (TriSepTM), were used characterized by SEM microscopic analysis, contact angles, free surface energy. oxidation, 2,3- 2,5-dihydroxybenzoic catechol, determined impact unreacted nanofiltration process investigated. It also checked what extent why they retained or...

The reactions of (N-(PhosphonoMethyl)Glycine) PMG with H2O2 in homogenous systems were investigated using 31P NMR (Nuclear Magnetic Resonance). These carried out two reaction modes: without UV radiation and under radiation. the degradations (0.1 mmol) by means 5–10 molar excess hydrogen dioxide (PMG-H2O2 = 1:5 1:10) degradation Fenton (PMG-H2O2-Fe2+ 1:10:0.05 1:10:0.1).
