Problem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity wa...

Aluminum sulfate shows a positive effect on preventing efflorescence of magnesium potassium phosphate (MKP) cements. Its influence the MKP cement properties and hydration is explored in this study. Compared to reference (Mg/PO4 molar ratio = 4, w/c 0.25), aluminum retards setting, increases compressive strength, has little short-term volume stability. slows down kinetics, decreases pH values, a...

The paper considers one of possible options for the waste-free processing dumped masses nickel slags, accumulated over years operation some enterprises. This process includes use hydroand pyrometallurgical processing, which results in three products: iron sulfate, ferrosilicon with a small admixture aluminum, and slag from smelting. has hardness 7-7.5 Mohs can be used as an abrasive powder sand...

In this work, different treatment methods for wastewater from textile washing operations in the Palestinian territories were studied. The goal of the treatment process was to enable the textile industry to reuse the wastewater in textile washing through simple, efficient, and cost-effective methodologies. Actual textile wastewater samples from local textile factories were used and were found to...

Introduction: The most important environmental problem of automotive industries is the produced wastewater due to its various processes. The flocculation and coagulation along with chemical sequestration are among important processes for removing contaminants from wastewaters. The aim of this study is to investigate the efficiency of coagulation and flocculation process along with chemical sequ...

Additional important properties to consider for additional analysis within the aerosol operations include the density, conductivity and ionizability of the element or compound. Magnesium is an extremely light metal, approximately 2/3 the weight of aluminum. Magnesium is extremely conductive, on par with copper and aluminum. Magnesium can be ionized with the energy available within the ultra-vio...

Rainwater collected in the Toluca region of Mexico with a pH 6.25 was treated an electrochemical process, and efficiency two supporting electrolytes were compared, one food grade (sea salt) other reagent (sodium sulfate). In first stage, rainwater characterized to detect COD content, turbidity, metals such as zinc, iron, aluminum, lead. Electrocoagulation treatment performed cell using aluminum...

Partial molar volumes of aluminium chloride, aluminium sulphate and aluminium nitrate have been determined in water rich binary aqueous mixtures of tetrahydrofuran (5, 10, 15, 20% by weight of tetrahydrofuran) with the help of density measurements. The density measurements were made by using Ward and Millero method and results have been analysed by Masson’s equation and interpreted in terms of ...

Blood and urine aluminium concentrations were studied in industrially exposed workers using electrothermal atomic absorption spectrometry. Welders and workers making aluminium powder and aluminium sulphate had higher concentrations in blood and urine than non-exposed referents. Workers in the electrolytic production of aluminium had higher urine but not blood concentrations than the referents. ...
