Abstract
The paper reports on the adsorption of iron colloid substances on activated carbon (PAC) Norit SA UF with using ultrasound. It is found that time of adsorption is equal to three hours. High-frequency electrical oscillation is 35 kHz. The adsorption capacity of activated carbon was determined and it is equal to about 0.25 mg iron colloid substances /mg PAC. The iron colloid substances size ranging from 30 to 360 nm was determined. The zeta potential of iron colloid substances which consists of iron (III) hydroxide, silicon compounds and natural organic substances is about (-38mV). The process of destruction iron colloid substances occurs with subsequent formation of a precipitate in the form of Fe(OH)3 as a result of the removal of organic substances from the model solution.

Summary
Keyword: iron colloid substances, adsorption, activated carbon, ultrasound 1. Introduction The present work relates to the problem of high-quality drinking water supply using processes of adsorption on activated carbon with using ultrasound with the oscillation frequency 35 kHz. In papers [1, 2] it is shown that iron containing groundwater of Western Siberian can be divided into two types. The second type is water where iron presents partly in the form of hydrocarbonate iron and partly as a complex with dissolved organic substances.
