Nanofiltration (NF) Process In Water and Wastewater Treatment
https://www.yasa.ltd/post/what-is-nanofiltration-nf-process-in-water-treatment Nanofiltration (NF) is a membrane treatment process primarily used to separate dissolved solutes from water. The process of movement of solvent through a semipermeable membrane from the solution to the pure solvent by applying excess pressure on the solution side is called nanofiltration. Nanofiltration (NF) ...

Adsorption of fluoride from water by surface-functionalized polyurethane foam
Surface-functionalized polyurethane foam (SPUF) showed an exceptionally high adsorption potential for defluoridation of drinking water. Kinetic experiments of fluoride adsorption on SPUF demonstrated quick adsorption in first 60 min and then achieved maximum adsorption (7.8 mg g−1). The adsorption isotherm was described using Bradley equation. The adsorption capacity of SPUF was significantly ...

The Role of Gas Sensing as a Drinking Water Purification Method
The processing of clean and safe drinking water and drinking water purification methods are an international issue. Estimates suggest that, if no further improvements are made to the availability of safe water sources, over 135 million people will die from potentially preventable diseases by 2020.1 Even within the UK, water purification and treatment is big business, with £2.1 billion ...

gaiasafe filter products for drinking water purification - Case Study
Problem In some water works chlorination of drinking water is used to eliminate mikrobes. Chlorinated water may have disagreable taste and smell. Some water works use aluminium salts to clean the water. This leads to low concentrations of aluminium in drinking water. Today it is known that aluminium may be toxic to men. Old piping installations inside or outside private homes often where made of ...

Challenges in the implementation of a national programme on drinking water
Provision of safe drinking water is a challenging problem requiring immediate attention. The skewed distribution of rainfall, inefficient use of water, presence of a variety of contaminants, such as fluoride, arsenic, iron and salinity, in most of the sources, and pollution by various economic activities have been the factors responsible for inadequate resources against the increasing demand due ...

Removal of 2-methylisoborneol from aqueous solution by cattle manure compost (CMC) derived activated carbons
The objective of this study is the synthesis of activated carbon derived from cattle manure compost (CMC) causing environmental problems using zinc chloride (ZnCl2) activation and to examine the suitability and performance of the prepared activated carbon (PAC) in removing 2-methylisoborneol (2-MIB) from aqueous solution. The influence of ZnCl2/CMC ratios and outgassing from the PACs on the ...

How does our nitrate removal system differ from reverse osmosis (RO) systems?
Reverse osmosis (RO) systems are the workhorse of the drinking water purification market. They are extremely effective in separating water impurities above a certain size (molecules or particles slightly large than a water molecule are filtered or removed). So, does RO eliminate or reduce nitrate? The answer is no. Some RO membranes will remove the nitrate molecule from the incoming water and ...

Water purification
Water purification is a process of removing undesirable chemicals, materials, and biological contaminants from raw water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (Drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacology, chemical and ...

Effect of ion (Al, Fe and Zn) co-doped TiO2 nanotubes on photocatalytic degradation of humic acids under UV/ozonation for drinking water purification
O3/UV/TiO2 was used to effectively decompose humic acids (HAs) in drinking water. A series of Al-doped, Fe-doped, Zn-doped and co-doped TiO2 nanotubes were successfully synthesized by a hydrothermal method. According to the characterization of ion-doped TiO2 nanotubes, Al3+ and Fe3+ ions occupied substitutional positions in the crystal lattice, and Zn2+ ions were partially dispersed in the ...
