Study of Metakaolin-Based Geopolymer with Addition of Polymer Admixtures
In the present work, metakaolin-based geopolymer including different polymer admixtures was studied. Different types of commercial polymer admixtures VINNAPAS® and polyethylene glycol of different relative molecular weight were used as polymer admixtures. The main objective of this work is to investigate the influence of different types of admixtures on the properties of metakaolin-based geopol...
متن کاملRemoval of Alkylphenols from Industrial and Municipal Wastewater
The results of the study of removal of nonylphenol, octylphenol and their ethoxylates from real industrial and municipal wastewater are presented. Industrial wastewater was pre-treated by coagulation with FeCl3 and adsorption on zeolite, before discharging into municipal sewer system. Their removal efficiencies in primary sedimentation tank of municipal WWTP were very low. From the practical po...
متن کاملRemoval of H2S and COD Using UV, Ferrate and UV/Ferrate from Municipal Wastewater
Background; The aim of this study is to compare UV, ferrate (VI) and UV/ferrate (VI) methods for removal of hydrogen sulfide and chemical oxygen demand (COD) from municipal wastewater under a continuous condition. Methods; The experiment was divided into three parts: 1) pollutants removal by using ferrate (VI) alone; 2) pollutants removal using UV alone; 3) pollutants removal using a combina...
متن کاملRemoval of Organic Compounds from Municipal Wastewater by Immobilized Biomass
Two porous ceramic carriers (internal active surface 0.04 m2 for carrier I and 0.2 m2 for carrier II) with immobilized activated sludge were the stationary filling of the reactors. Municipal wastewater was treated at hydraulic retention time (HRT) from 70 to 15 min. The efficiency of organic compounds removal from wastewater changed for reactor I from 85.2 to 93.8%, for reactor II from 62.9 to ...
متن کاملApplication-Oriented Chemical Optimization of a Metakaolin Based Geopolymer
In this study the development of a metakaolin based geopolymeric mortar to be used as bonding matrix for external strengthening of reinforced concrete beams is reported. Four geopolymer formulations have been obtained by varying the composition of the activating solution in terms of SiO₂/Na₂O ratio. The obtained samples have been characterized from a structural, microstructural and mechanical p...
