Novel H2O2–MnO2 system for efficient physico-chemical cleaning of fouled ultrafiltration membranes by simultaneous generation of reactive free radicals and oxygen

Toward the end of the 20th century fundamental theories of oxidation, combustion, friction, deterioration, corrosion and others were adapted to chemmotology systems: proposed an oscillatory-homogenous theory of the formation of free radicals in hydrocarbonated nature; demonstrated unsuitability of “physical” model of combustion for a description of working processes of engines; worked out a theory of boundary processes of grease and friction as applied with conjugate details; worked out the general patterns of tribochemical reactions in lubricant nature; developed the basis of theory of physico-chemical mechanics of pseudocolloidal systems. At the present moment established the general patterns of the effect of quality of combustion and composition of fuel during the period of delay of ignition, speed and volume of burning of hydrocarbons ; worked out a concept of quasiciliary formation of fuels, defining their condition of metastable state; proposed mechanism of abnormally - fast internally flaming gasification of dispersing carbohydrate ; worked out an electro-kinetical model of quality state of engine oils in static and dynamic conditions and many others . Introduction of relevant theoretical basis will provide quantitative description of chemotological processes.

Cleaning Methods

Each machine and energetic equipment needs maintenance or cleaning time. Energetic equipment needs more regular cleaning so it works well and reliably, and the heat transfer is permanent and there is no energy loss. The inner surface of heating systems are successively covering during their operation, due to the chemical and physico-chemical reactions, solid, some dirt, minerals and corrosion products. It is therefore advisable to regularly clean and service these devices. The article deals with the distribution of exchangers, formation of sediments and corrosion products associated with their operation. In addition, the article describes the types of internal surface cleaning methods. The whole article ends with a chemical cleaning experiment, where the heat exchanger clogged with mineral deposits was cleaned. The defectoscopic images show how the chemical can remove all deposits and restore the exchanger flow to its original state.
