Treatment of Real Textile Wastewater by Using Potassium Ferrate(VI) and Fe(III)/H2O2. Application of Aliivibrio Fischeri and Brachionus plicatilis Tests for Toxicity Assessment
Journal Title: Fibres and Textiles in Eastern Europe - Year 2019, Vol 27, Issue 3
Abstract
The paper presents the possibility of applying combined chemical oxidation processes using potassium ferrate(VI) (K2FeO4) and Fe(III)/H2O2 for the treatment of real wastewater from the textile industry characterised by an increased content of organic substances (COD = 1920 mg O2/L). The use of both processes under optimal conditions included the use of the RSM method (Response Surface Methodology) in order to make it possible to decrease the COD of the wastewater by 75.4% (final COD = 472 mg O2/L). The toxicity of wastewater treated under the most favourable conditions, determined using two test organisms (Aliivibrio fischeri and Brachionus plicatilis), decreased by 33 and 45%, respectively. In some cases the method described can be used on a larger scale.<br/><br/>

Natural Fibres From the Bark of Mulberry Branches for Textile Application
Fibers with low gum content were extracted from the bark of mulberry branches by a combination of bacteria and peroxide treatments. The bark of mulberry branches, with 30% cellulose, is a copious and inexpensive source o...
Optimisation of Operational Parameters for Nonwoven Sheaths of Water Absorbing Geocomposites in Unsaturated Soil Conditions
This study analyses tests influencing the selection of nonwovens for water absorbing geocomposites. The task of the nonwoven is to capture water infiltrating into the soil and to direct it to the superabsorbent located...
