Rudkovska O. Stabilizing water treatment systems for environmentally friendly water consumption in the energy sector

In dissertation work there has been developed new spume forming stabilizators and metal corrosion inhibitors based on the phosphoric acid and methylol sulfonates. The efficiency of new reagents for the protection of water circulation cooling systems from corrosion and spume formation was estimated. For example, the sodium salt dimetilensulfonat of phosphinic acid (SSDPA) is an effective spume forming stabilizer at Kv=2,63 and the dose of reagent 2 mg/dm3 stabilization effect was at 78,96 %. This reagent is also an effective inhibitor of the corrosion of metals (St3 steel, M2 copper, A2 brass), the protection level increases when the zinc ion (Zn2+) is at a dose of 2 mg/dm3. The influence of the level of salinity and water hardness on its corrosivity at different temperatures and the efficiency of the inhibitors in the given conditions were studied. First, the parameters of mine water treatment processes from uranium compounds with the help of sedimentation, flotation and filtration depending on type, ratios and concentrations of coagulants and flocculants were determined. First, the processes of water purification from uranium and sulphates with its calcification in the presence of aluminum coagulants were studied, the dependence of the type of water treatment and dosage of reagents, environmental characteristics were defined. The technology of synthesis of new highly corrosion inhibitor and spume formation was developed - SSDPA. The technology of reagent softening of mine and circulating waters was described.
