چکیده
Physikalisch-chemische Beliandlungsverfaliren wurden hinsichtlich ihrer Wirksamkeit bei der Eliminierung von nichtionischen und anionischen Tensiden aus Klaranlagenablaufen gepriift. Flockulierung mit Eisen(III)-chlorid ergab eine Eliminierung von 79%; eine Batchadsorption mit Hive dreier verschiedener Aktivkohlen brachte 90 % Eliminienrng bei den anionischen und mehr ais 95% Eliminierung bei den nichtionischen Tensiden. AIS effektivster Weg bei der praktischen Anwendung envies sich die kontinuierliche Flockirlierung mit anschlieJ3ender Sandjiltration und darauffogender Adsorption.

Activated Sludge Treatment of Ethoxylate Surfactants at High Industrial Use Concentrations
The primary degradation of a linear alcohol ethoxylate (AE) and a branched nonylphenol ethoxylate (NPE) was investigated in bench-scale activated sludge units treating a synthetic sewage feed. Biotreaters were gradually adapted to 10-100 mg/J surfactant and effluents monitored for loss of nonionic ethoxylate, foaming, feed BOD removal, nitrification and biosolids growth. Both surfactants were d...
متن کاملRemoval of Surfactants from wastewater by Rice Husk
Surfactants are one of the major components (10- 18%) of detergents and household cleaning products and are used in high volumes in developed countries. In the present research work, the ability of rice husk as a low cost adsorbent for anionic and nonionic surfactants in wastewater has been studied. The maximum removal efficiency for anionic surfactants was 97%, in an aqueous solu...
متن کاملReactive Dye Removal from Aqueous Solution by Sorption
* E-mail: [email protected] ABSTRACT Effluents of textile dyeing are characterized by intense colour, chemical oxygen demand, suspended solids and a variety of refractory matter, such as heavy metals and nonionic surfactants. Strong colours may reduce light penetration, thus affecting the growth of plants and having impact on invertebrate and other forms of wildlife. There are a large numbe...
متن کاملWWTPs’ effluents or through infiltration where land application is employed as a method for disposal of effluent
A local wastewater treatment plant (WWTP) experiencing poor nitrification tracked down high level of surfactants in the plant’s influent and effluent. The aims of this project were to assess the potential inhibitory effect of surfactants on activated sludge processes. The effect of the presence of TergitolNP-9, TrigetolNP-7, Trigetol15-S-9, dodecylbenzene sulphonate (SDBS) and sodium dodecyl su...
