Point-of-use household water filters (POU filters) are increasingly used to protect consumers from lead in drinking water, but there have been anecdotal reports of premature failure due to clogging when iron is present. To evaluate this concern in relation to lead removal and treatment costs, POU pitcher filters were exposed to water conditions containing lead and/or iron and tested to 100% of their rated capacity or until they clogged. Iron levels above the 0.3 mg/L Secondary Maximum Contaminant Level (SMCL) resulted in rapid clogging, affecting both treatment costs and consumer satisfaction. At 0.3 mg/L iron (Fe), half of the six POU filters tested clogged prematurely between 38% and 68% of the rated capacity. At 1.0 mg/L Fe, four out of six POU filters tested clogged prematurely, and all clogged prematurely at 20 mg/L.

Heavy metal pollution caused by the indiscriminate disposal of toxic heavy metal wastewater has become one of the serious water environmental issues. In this study, a novel NH2-PAA/Alginate hydrogel with double network interpenetrating structure was constructed with alginate, acrylic acid, and other raw materials. Characterized by scanning electron microscope, this hydrogel shows a three-dimensional porous structure, which would be useful in adsorption process for its high diffusion coefficient. The results of adsorption experimental show that the NH2-PAA/Alginate possessed the well adsorption capacity when pH was above 3.5, the maximum adsorption capacity calculated by Langmuir was 176.5 mg/g, and the adsorption equilibrium can be achieved within 150 min. In addition, the NH2-PAA/Alginate has good recycling ability and stability. The results of X-ray photoelectron spectroscope analysis reveal that the Cd(II) exchanged with Ca(II) and then coordinated with amino and hydroxyl groups in NH2-PAA/Alginate. The NH2-PAA/Alginate hydrogel can deal with all kinds of heavy metal ions and is a potential material for heavy metal adsorption.
