Elevated levels of iron in groundwater in Prey Veng province in Cambodia: a possible factor contributing to high iron stores in women
Iron is a natural element found in food, water and soil and is essential for human health. Our aim was to determine the levels of iron and 25 other metals and trace elements in groundwater from 22 households in Prey Veng, Cambodia. Water analyses were conducted using inductively coupled plasma–mass spectrometry and optical emission spectrometry. Compared to the 2011 World Health ...

Adsorption of methylene blue from aqueous solutions using water treatment sludge modified with sodium alginate as a low cost adsorbent
In this research, aluminum-based drinking water treatment sludge is used as a starting material and immobilized by sodium alginate to develop low cost adsorbent for the removal of methylene blue (MB) from aqueous solutions. The studied variables included pH, adsorbent dose, initial MB concentration and contact time. Characteristics of the adsorbent were also studied using scanning electron ...

Treatment of drinking water containing iron using Electrocoagulation
Electrocoagulation (EC) technique was adopted for the treatment of iron containing drinking water using a reactor of 3 l capacity having 1 l liquid volume. Experimental investigation was carried out to observe the effect of different operating parameters such as pH, current density, inter-electrode distance and conductivity on the removal of iron from the iron-rich aqueous solution prepared with ...

Toxicity evaluation of polymeric ferric sulphate
Toxicity evaluation of water treated with polymeric ferric sulphate (PFS), an aluminium-free coagulant, was conducted in this research. Six-week old male F344/N rats exposed to PFS-treated water for three months did not show any obvious pathology as observed histologically or in clinical chemistry compared to rats given tap water. There was no significant difference in body weight gain in the ...

Drinking water quality monitoring using trend analysis
One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

Performance of Moringa oleifera extracts and Sudfloc as coagulant aid in raw water treatment in Mauritius
Coagulation experiments were done using raw water samples from two treatment plants (herein referred to LMTP and LNTP) in Mauritius in jar tests using Moringa oleifera (MO) extract and Sudfloc. Both coagulant aids reduced alum consumption. Sudfloc was required in low concentration as compared to crude extracts of MO. On samples from LMTP, salt extract of MO (MOSE) was six times more efficient ...

A promising approach of reject water treatment using a tidal flow constructed wetland system employing alum sludge as main substrate
This study examined a novel reuse of alum sludge, an inescapable by-product of drinking water treatment process when aluminium salt is added as a coagulant, as the main medium in a laboratory-scale multi-stage constructed wetland (CW) system for reject water treatment. Such reject water is a main concern in municipal wastewater treatment plant (MWWTP) for increasing the organic and nutrient ...

Illness from tap water
Bacteria and virus In every water pipe there are billions of bacteria and virus in layers of sediment and sludge. When released in small numbers, they are instantly killed by the chlorine in the water, but when pieces of sludge are ripped off by pressure changes in the pipes, there is not enough chlorine and you may get “intestinal flue” or some more serious ...

A novel alum-sludge based Constructed Wetland system to reduce pollution effects of agricultural run-off: first results
This paper is a research brief highlighting the development of a novel alum-sludge based Constructed Wetland (CW) system aimed at reducing the pollution effects of agricultural run-offs. Alum sludge is a by-product of drinking water treatment plants where aluminium sulphate is used as coagulant. The alum sludge cakes were used as the main support matrix in the constructed wetland system, having ...

Do aluminium concentrations in drinking water inhibit cultivation of
Escherichia coli? In spite of reliance on Escherichia coli as an indicator of fecal pollution in water resources, including potable water, relatively little is known of its ecology and persistence. It is particularly important to be able to accurately detect E. coli presence and quantity in treated potable water because of potential human health effects from consumption of contaminated water. Presence of even a ...
