Application of integrated acoustic method in processes of water treatment and water disposal in agglomerations of metallurgical enterprises

A modern metallurgical enterprise and water treatment plants in the cities in which they are located are among the largest consumers of natural water, and their water supply and sanitation systems are among the most important elements, since the environmental situation in the agglomeration and the quality of life of its residents, including employees of ferrous metallurgy enterprises, directly depend on the quality of their work. To improve the quality of water purification (natural, recycled and wastewater) from finely dispersed (TD) – grades -5 μm, suspended solids (BB) and heavy metals (TM), as well as from pathogenic bacteria (BB) and algae (VD), it is proposed to use the integrated acoustic method (CAM) more widely, in particular water treatment and sanitation systems of agglomerations of ferrous metallurgy. The main differences of the CAM method are: non-reactivity; low power consumption (0.5-5.0 W/m3 of water); autonomy (no operator presence required); the use of the same set of sonar emitters and power amplifiers with a set of removable digital media for simultaneous solution of a range of applied tasks not only in the field of water supply and sanitation, but also providing highquality recycled water. At the same time, the CAM method can be applied both independently and in the chain of existing water supply and sanitation systems at the enterprise. New results of using the CAM method to improve the quality of water purification (natural, recycled and wastewater) from TDVV, TM (manganese), BB and VD, both in the northern regions (Arkhangelsk and Murmansk regions, etc.) and in the southern regions (Astrakhan and Rostov regions, etc.) are presented.
