The main, the most acute problem of barometric technology today is reagent provision. For its stable and trouble-free operation, a complex of expensive and unique chemical reagents (biocides, antiscales, washing compositions) is required. Each manufacturer develops his own chemical composition for a certain membrane type. This leads to a significant cost rise of reagents, as well as creates a dependence of the consumer technology from a particular supplier. However, these reagents do not always meet the quality requirements - despite the guarantees provided by manufacturers, the equipment fails before the due service life as a result of deposits in the pores and on the membrane surfaces. To develop a more effective washing composition, it is required to determine the type and consist of these deposits. The report illustrates the methods for determining the consist and type of deposits on reverse osmosis membranes. The solution of the problem of reagent provision for the example of the wastewater treatment plant at the Ashalchinsky field of the extra-viscous oil of PJSC “Tatneft” is presented.
