Service Sp. z o.o. strictly observes the principles of transport, storage and disposal of waste as well as continuously monitors environmental parameters, thus, minimalizing potential threat of adverse impact on the environment.
Waste is transported to the area of the plant with a specialist car fleet which meets the requirements specified for road transport of hazardous products. Collected waste is weighed and registered according to the affecting legal regulations and stored in attested tanks, receptacles and containers in precisely defined sites.
All installations were built on the surface made from tight, concrete pavement limited with embankments for protection of underground water. Storage sites are also highly insulated from the ground. Roads in the site of the plant have tight coating. Additionally, storage tanks are placed on anti-spill trays from which drain is connected to the industrial sewage system and directed back to the process through the ballast water treatment plant (OWB).
Both the network of industrial sewage system and rain sewage system to which rain sewage from squares is transferred are completely resistant to chemical substances. In all installations of Port Service there is a possibility to apply a closed sewage management. The pavement tightness control is periodically conducted in the scope of local monitoring with piezometers and test results confirm that the safety devices used in the site of the Company practically make it impossible for contamination to reach soil and groundwater.
A multi-level system of combustion gas treatment was installed in the installation for thermal waste processing. In the initial neutralisation process, combustion gas ingredients are subjected to impact of high temperature. The next stage of combustion gas treatment is cooling. As a result of instant temperature decrease, radicals are destroyed and the amount of forming dioxanes and furans is significantly decreased. Next, spraying with a solution of NaOH is conducted in alkaline drilling fluids as the result of which, for example, sulphur and chlorine compounds are neutralised and, in effect, sodium salts soluble in water are created. Combustion gases thus purified are transferred to the electro filter where the finest, floating dust particles which were not washed out in the previous devices are removed. Sludge created during wet processing (attemperator, alkaline washer, electro filter) is transferred to a settling tank where phase separation takes place.
Sediment precipitated on the floor is transferred to the press so that upon dehydration it can turn into so-called filter cakes which are removed to the storage area of hazardous waste. Whereas filtrate and supernatant water created in the settling tank returns to the circuit and is transferred to combustion gas attemperator.
The final stage in a gas combustion treatment process is removal of harmful compound residues (dioxanes and furans) in the active carbon deposit in the carbon adsorber. Thus purified combustion gas is released to the environment through the 50m high emitter. Application of a multi-level system of combustion gas treatment allows to achieve lower emission values than these required by the national and EU law. Additionally, composition and volume of emitted combustion gases are monitored in a continuous mode thanks to the most modern system of continuous measurement of combustion gas parameters.
