Denatured filtering media are used in the filtration process for iron removal, which can improve water quality during initial filtering.

Discussion on fluoride removal technique with modified filter media;

A conception that zero-valence iron nonoparticle,as a kind of modifier,can be used as modified filter media is put forward.

The removal efficiency of phosphorus in drinking water by modified filter media, especially iron oxide-coated sand has been studied.

Adsorption of fluoride from water by preparing coated media;

In this paper static and dynamic analyses on the efficiency for removal of organic matter are made through four groups of absorption experiments with preparing coated media.

Influence of filter material on the effect of removal of Fe2+and Mn2+from groundwater;

Presented in the paper is a study of molecular weight distribution of organic matter and the removal of organic matter by using coated filter media and activated carbon in combination.

In this paper,an investigation on the regularities for the increase of head loss in the process of iron removal through filtration with coated-media is carried out, and a formula for calculating head loss is obtained and verified by the experimental data.

In this paper,the dynamic procedure for the removal of iron with coated-media is analyzed,and a dynamic differential equation is obtained and verified by the experimental data in the filtration.
