Drinking water treatment

This study looked at two arsenic removal technologies, method Bucket Treatment Unit and removal using citrus lime, lemon and filter. The method Bucket Treatment Unit used zero-valent iron and removal using citrus lime, lemon and filter used photochemical oxidation of arsenic. The citrus lime, lemon

Access to a sufficient quantity of water of adequate quality for human consumption is a global problem. Nowadays, among the 1 billion people estimated to lack access to improved water sources and sanitation worldwide, rural populations are disproportionately underserved. As a consequence, sustainabl

The effect that biofiltration had on the fouling behaviour of several commercial nanofiltration (NF) membranes used for drinking water treatment was investigated using a bench-scale set-up. A dual-media anthracite-sand biofilter was used to pretreat a humic acid-laden solution spiked with a solution

Low pressure membrane filtration processes are increasingly competing against conventional surface water treatment plants. In comparison with conventional processes, UF technology has many advantages, but it is also important that a kind of membrane is suitably selected and operated. In this paper,

The fouling characteristics of ultrafiltration membranes used in drinking water were investigated when used alone and when used in an integrated biofilter-membrane system to treat a humic-acid laden solution. Membrane strands from sacrificial modules operating in parallel with bench-scale modules we

The objective of this pilot study was to evaluate the performance of a GAC postfilter-adsorber for the removal from the drinking water of Athens, Greece, of the two main groups of chlorination by-products, trihalomethanes (THMs) and haloacetic acids (HAAs), as well as of dissolved organic carbon (DO

During most water treatment processes, spent filter backwash water (SFBW) is generated. Reuse of SFBW is of concern because of the possible recycling of heavy metals, precursors for disinfection by-products and microorganisms. Innovations in membrane technology, especially in micro- and ultrafiltrat

Fouling layer formation in membrane processes and the role of bacteria in it were investigated using rRNA-targeted fluorescently labelled oligonucleotides. In a laboratory-scale flat-channel test unit, nano- and ultrafiltration of an oligotrophic reservoir water were performed. The bacterial composi

In China, many water supplies depend on conventional water treatment. Due to unfit soil and water conservation in some regions of China, conventional water treatment has showed some defects for the poor quality of water resource. In addition, advances in membrane technology and increasing requiremen

Memcor® Continuous Microfiltration (CMF) is a technology that is very efficient for the clarification and disinfection of karstic waters for the production of drinking water. In Héricourt-en-Caux (Normandy), a Memcor® CMF plant is treating a particularly difficult water with a background level of tu
