A real danger for the quality of subterranean waters, however, is their overexploitation, which may increase the inflow of adjacent surface waters. It is also worth remembering that, in many countries, access to subterranean waters is very limited; there, the main source of bottled water is desalinated sea water ( Al‐Mudhaf and others 2009 ).
Pressure-driven membrane processes, such as reverse osmosis (RO) and nanofiltration (NF), are preferred solutions for salinity reduction in ground, surface and sea waters as well as in mining and
waters in excess of 1.5 mg/l and skeletal fluorosis beyond 3 mg/l. Among the different recognized membrane distillation configurations, vacuum membrane distillation is applied in the present work for fluoride removal. The effects of different
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium .
24/11/2015 · Membrane crystallization (MCr) is an emerging membrane process with the capability to extract simultaneously fresh water and valuable components from various streams. In the current study, the potential of MCr for produced water treatment and salt recovery was demonstrated.
Polytetrafluoroethylene was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont.As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty." ." Since Plunkett was measuring the amount of gas used by
1/2/2021 · The trends of normalized flux (NF) for different feed waters are shown in Fig. 1.The initial permeate flux of virgin PTFE membrane was 8.1 ± 0.46 L/(m 2 h), which declined to 53.3% for the Xuanwu Lake, 46.3% for the Nan Lake and 46.9% for the Qinhuai River, respectively.
Keywords: Vacuum membrane distillation; fluoride; PTFE hydrophobic microporou membrane. 210 S.P. Chaurasia et al 1. Introduction With increasing global population, the gap between the supply and demand for water is widening and is reaching such alarming levels that in some part of the world, it is passing a threat to human existence [Li 2009].

Alkalinity was measured by titrating HNO 3 into a 50 ml water sample that had been filtered through a 0.45 μm polytetrafluoroethylene (PTFE) membrane filter. The Gran function plot method was applied to obtain bicarbonate ion (HCO 3 − ) concentration from the alkalinity value (Rounds, 2015 ).
