Advanced Water Treatment Solutions for the Food/Beverage Industry
The agricultural/irrigation industry is one of the most demanding users of water for process applications. The availability of a sustainable supply of clean water is a necessity. Water shortages, reduction of water quality, and environmental issues, have led to an increased awareness of the use of both treated waste water as well as the purification of well water with higher salinity or other ...

Use of various agricultural wastes for the removal of heavy metal ions
There is a need to develop innovative and alternative technologies that can remove toxic heavy metal pollutants from wastewater. In this study, two agricultural residues, cotton stalks and apricot seeds, were used to adsorb copper and lead in solutions. Sorption capacities of agricultural wastes were significantly affected by solution pH, adsorbent mass and adsorbent particle size. The adsorption ...

How the Aquamonitrix real-time nitrate and nitrite analyser allowed a drinking water supplier to lift a long-standing Do Not Consume notice - Case Study
Compared with market-leading UV-based nitrate analysers, Aquamonitrix offers a key advantage in statutory limit monitoring applications at the outlet of drinking water treatment plants. In addition to providing high-accuracy, real-time nitrate monitoring, Aquamonitrix simultaneously provides a specific, high accuracy real-time nitrite measurement, with a lower limit of detection of just 0.05 ...

Reports: Rural U.S. drinking water must be protected
State and federal officials must act to safeguard drinking water supplies throughout the United States, particularly in rural areas and small towns, according to investigative reports published in December 2016. Lead contamination may be affecting 4 million or more Americans, according to reports by USA TODAY and Reuters. Water systems in small communities are not scrutinized as closely as ...

Biosorption of lead(II) by free and immobilised fungal biomass of Phanerochaete chrysosporium: a comparative study
An efficient metal biosorbent was developed by immobilising fungal biomass within matrix of loofa sponge (FBILS). At biosorption equilibrium FBILS removed 137 mg Pb(II) g-1, which was 24.3% greater than 110 mg Pb(II) g−1 free fungal biomass. The equilibrium biosorption data fitted well the Langmuir model. The experimental data, when applied to the pseudo-first and second-order kinetic models, ...

Removal of heavy metals from aqueous solution by limestone
This study focused on the removal of Pb(II), Cd(II), Cu(II), and Zn(II) using reagent solutions by natural limestone in a batch system. The sorbent, collected from the Late Cretaceous limestone beds, Tunisia, was characterised by X–ray diffraction (XRD), chemical analysis (XRF) and infrared spectroscopy (FTIR). XRF showed that the studied limestone contained high amount of calcium carbonates. XRD ...

Water technology magazine features an article on ITS president
Lead contamination — as well as other metals that could be found in plumbing systems — presents serious risks for members in a household, especially children. Recent studies show that lead can affect children’s developing brains when it enters the body in abundance and displaces zinc and ultimately disrupts brain cell growth. For adults, approximately 80 percent of lead that is ...

Case histories of using tin technology to control corrosion in water systems
Stannous chloride is an alternative corrosion control in aqueous systems. Stannous chloride’s effectiveness as a better corrosion inhibitor has been demonstrated in both municipal drinking water and industrial cooling water applications and its use has a reduced impact on rivers and streams. Orthophosphate and other phosphate compounds are the most common treatments for reducing corrosion ...
