1. Introduction According to the World Health Organization guide lines, the permissible level for total arsenic in drinkingwater is 10 ng/mL. Although no such limit exists for food products, the Food and Agriculture Organization / World Health Organization (FAO/WHO) recommend an intake no greater than 15 μg ...
is neutral in charge, while As (V) species are negatively charged. Removal efficiencies for As (III) are usually less than those of As (V) because of As (V)’s negative charge. In many cases, pretreatment of As (III) to oxidize it to As (V) may be necessary to efficiently remove arsenic from drinking ...
-ter. The WHO (World Health Or ga ni za tion) recommends that the arsenic content in drinkingwater should not ex ceed 10 µg/L. In many countries, in cluding the USA and EU member states, this limit is not merely a recom-mendation but a legal requirement. Com pli ance with this limit value is usually ...
ResinTech SISIR-900 is a granular aluminum oxide based adsorbent. SIR-900 is supplied as an active oxide media based on porous aluminum oxide. ResisinTech SIR-900 is intended for removal of fluoride from water. It can also be used for the removal of arsenate, selenate, and lead from potable water. SIR-900 is ...
Arsenic is part of the earth’s crust and is a naturally occurring element found in rocks, soil and water. It is both odorless and tasteless. Natural concentrations of arsenic in soil typically range from 0.1 to 40 mg/kg. Arsenic can be dangerous to humans when released into drinkingwater ...
ResinTech ASM-10-HP is a chloride form arsenic selective hybrid anion exchange resin. ASM-10-HP has hydrated iron oxide monoatomically dispersed throughout the polymer. It captures arsenate first by ion exchange and then by absorption into the iron oxide hybrid. ResinTech ASM-10-HP is intended for arsenic removal ...
Arsenic TestingArsenic is a naturally occurring contaminant of ground water in several areas of the world. Unfortunately the health effects of even very low levels of arsenic in drinkingwater are serious leading to a variety of conditions collectively known as arsenicosis. For many affected ...
MetalGuard is the first fully automated online trace metals analyzer for monitoring municipal and industrial water and wastewater. The system provides real-time, multi-stream analysis for a range of trace metal contaminants. MetalGuard delivers accurate and reliable results (up to 1 ppb or ± 15%, ...
De Nora offers the SORB 33 ARS, a standard pre-engineered product line of adsorber systems for the removal of arsenic from potable ground water sources. The ARS product line features our proven and effective arsenic removal ...
Unlike the more complex precipitation. and flocculation methods or the rather. expensive ion-exchange technique with. its limited selectivity for pentavalent. arsenic, Harbauer presents a new and. intriguingly simple adsorption technique. for the removal of arsenic from ground. and drinkingwater. Its ...

in the US, there is enough fluoride in the water to cause fluorosis. Arsenic is a naturally occurring element found in rocks, soil and water. Apart from industrial waste streams, contamination by arsenic and fluoride can occur from the natural dissolution of minerals into groundwater streams. High fluoride and ...
