The Siersza Power Plant in Trzebinia is a part of The Southern Power Concern S.A. Katowice since 2000. It is situated in the north-western part of the Malopolska Voivodeship in the Trzebinia administrative territory and was constructed between 1962-1970 as a system power plant.
Water Treatment Plant (SUW)
The Siersza power plant uses water for technological purposes, mainly in the boiler and cooling cycle (it has a closed cooling water system).
Water transferred to the boiler cycle has to conform to high requirements in terms of chemical cleanness. Hence, it is specially prepared in the water treatment plant (SUW) with the use of coagulation and deminaralisation processes.
The system which prepares water consists of the following devices:
an accelerator, a water heater, a coagulated water tank, slag filters, coal filters and ion exchangers.
Raw water (the mixture of surface water from the nearby stream and underground water from a deep well located along the stream) is processed in the coagulation process with the use of ferric sulfate and an appropriate flocculent in the accelerator. Then it is transferred to the slag filters and coal filters to remove the suspension and reduce the oxygen consumption. Filtered water is transferred to the network of ion exchangers and then to cation exchangers and finally to CO2 eliminators. Then it is applied to two-layered anion exchangers and next to double ion exchangers. The system is equipped with three technological lines of the efficiency of 35 m3/h each. The exchangers are filled with ion exchanging material produced by the company Dow. Mineralised water is transferred to storage tanks. There it fills the boiler cycle. The demineralisation system functions within the counterflow technology system with a classical water flow through ion exchangers from top to bottom during functioning and with a counterflow regeneration.
Raw water used in the cooling cycle is processed with the use of the lime decarbonation and coagulation using ferric sulfate performed in the accelarators.
The whitewash suspension is used in the process. The suspension is prepared in the sulfur removal system. Sediments precipitated in the accelerator are transferred as a dense suspension to the sulfur removal system or - after dehydration - on the filter presses are applied with coal to the boilers.
