Works on the slag clarifier in the Southern Poland Power Company Jaworzno III Power Plant are finished. The pace of works is best shown by the fact that in February 2008 the land lot was empty and now there is a big building consisting of the following chambers: settling, clarifying and return water as well as two pump stations (for drainage and return water).

The data given below are the best possible evidence confirming the scale of the enterprise: in the works high season there were 100 workers on the construction site. 24 thousand tons of soil were transported away, 10 thousand cubic meters of concrete (one thousand big cement mixers) were used as well as 900 tons of steel. The thickness of the clarifier bottom amounts to 1 meter and is made of premium quality concrete ensuring tightness, the walls are from 70 to 90 centimeters thick. Ground works were carried out at the depth reaching almost 8 meters.

The investment is the consequence of the planned closing of the present waste storing place situated in Myslowice – Dzieckowice. The enterprise was carried out by the set up syndicate: Instal Krakow Plc., Energoprojekt Katowice Plc., Bielsko-Biala Industrial Construction Company Plc. On behalf of Jaworzno III Power Plant, the works were supervised by engineer Jerzy Wrona. Modernisation of the present deslagging network will contribute to the increase of slag recovery and the clarified water will be fed back to the installation water circuit. The recovered slag will be forwarded for further industrial usage and the only waste from the process will be the gravel from the clarifier chambers which will be used for the production of construction elements and for the degraded land reclamation. This is an ecological technology which does not contaminate or pollute the environment. The slag educed in the process will be extracted by means of a gantry crane grab mounted over the clarifier chambers and it will be directly loaded onto trucks or wagons. The clarifier will work on fortnight cycle – seven days for filling and seven days for emptying.

The commission of the clarifier has a significant influence on the exploitation costs cutting, above all the amount of the used energy will fall. The distance between the pump station and the slag recovery place will also be reduced. What is more, the return water pump station in Dzieckowice will be shut down.

The investment was co-financed by the European Union from the European Regional Development Fund and by the National Fund for Environment Protection and Water Management.
The landfill exploitation history in case of Jaworzno III hearth waste goes back to 1977. 30 years ago, pursuant to the Minister of Mining Industry decision the transport of slag and ash to the landfills was commenced. Ten years later, by virtue of the social agreement signed with the municipality of Myslowice, Jaworzno III Power Plant obliged to reduce the landfill exploitation and to carry out a number of works in aid of the district Dzieckowice.

Two years later, in 1990 due to the landfill absorptiveness exhaustion and taking into account Dzieckowice inhabitants’ postulates, the construction of pneumatic ash transport system was commenced. Its completion in 1994 enabled the company to stop locating ashes in the landfill.
In 1995 the environment reclamation process was started, however, one chamber was left as temporary ash storing place.
In February 2008 the erection of slag clarifier was commenced on site of Jaworzno III Power Plant. Its commissioning will enable to stop the no 1 chamber exploitation and it will be used only in emergency situations. The realisation of this enterprise was undertaken by the syndicate of the following companies: Instal Krakow Plc., Energoprojekt Katowice Plc., Bielsko-Biala Industrial Construction Company Plc.
The ceremonial commissioning took place on November 24th, 2008 with the participation of: Pawel Silbert – mayor of the city of Jaworzno, Tadeusz Chowaniak – Vice-mayor of the city of Myslowice, Stanislaw Tokarski – the Southern Poland Power Company Plc.
