Alum Coagulation

Equilibrium and kinetic analysis of phosphorus adsorption from aqueous solution using waste alum sludge.

Excess phosphorus (P) in wastewaters promotes eutrophication in receiving waterways. A cost-effective method such as use of novel low-cost adsorbents for its adsorptive removal would significantly reduce such impacts. Using batch experiments, the intrinsic dynamics of P adsorption by waste alum sludge (an inevitable by-product of drinking water treatment plants) was examined. Different models o...

How alum works

For more than 70 years, alum has been used as a trusty aide to improve antibody responses to vaccines. But how this aluminum-containing compound boosts the response to vaccines has been a mystery. On page 869, Kool et al. expose its mysterious mechanism; they find that alum causes cells to produce a stim-ulator of dendritic cells (DCs). DCs were once the favored hypothetical link between alum a...

Alum Induces Innate Immune Responses

Nitrate removal from water using alum and ferric chloride: A comparative study of alum and ferric chloride efficiency

Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. Methods: In this research...
