Investigation of quaternary ammonium silane-coated sand filter for the removal of bacteria and viruses from drinking water.
AIMS To develop an anti-microbial filter media using an attached quaternary ammonium compound (QAC) and evaluate its performance under conditions relevant to household drinking water treatment in developing countries. METHODS AND RESULTS Silica sand was coated with dimethyloctadecyl [3-(trimethoxysilyl) propyl] ammonium chloride via covalent silane chemistry. Filter columns packed with coated...
متن کاملA new Method for the Removal of Ammonium from Drinking Water Using Hybrid Method of Modified Zeolites / Catalytic Ozonation
Introduction: Ammonia in form of ammonium ions is toxic and could decrease the dissolved oxygen in water and endanger the aquatic life. The aim of this study is the removal of ammonium using oxidation and adsorption by catalytic ozonation and clinoptilolite zeolite, respectively. Methods: The research method is Experimental. First, optimal pH of ammonium adsorption on carbon catalyst (5 g/L), ...
متن کاملBiological nitrate removal processes from drinking water supply-a review
This paper reviews both heterotrophic and autotrophic processes for the removal of nitrate from water supplies. The most commonly used carbon sources in heterotrophic denitrification are methanol, ethanol and acetic acid. Process performance for each feed stock is compared with particular reference nitrate and nitrite residual and to toxicity potential. Autotrophic nitrate removal has the advan...
متن کامل"investigation of roughing filter efficiency on turbidity and parasite egg removal from raw water"
slow sand filters are as a proper technology for pre-treatment of raw water, with a fine and medium trubidity in small communities in developing countries. thus, with a minimum operation cost and minimum need for expest bodies have the maximum efficiency. the purpose of this research is carried out to evaluate the efficiency of two processes of horizontal flow roughing filter and vertical flow ...
متن کاملA Review on the Design Criteria of Biological Aerated Filter for Cod, Ammonia and Manganese Removal in Drinking Water Treatment
The design criteria of biological aerated filter (BAF) were reviewed in order to design an effective process for organic and inorganic contaminants removal in drinking water, particularly, COD and ammonia removal. The review was mainly focused on the height and diameter dimensions for the BAF process system as well as the removal efficiency and the type of media used. In addition, the review al...
