Sludge Disinfection

The bacterial content of non-disinfected sludge is very high. The two-stage disinfection performed with the PACS system decreases the bacterial content of the sludge from several millions to less than hundred. This provides new possibilities for utilising the sludge produced in wastewater purification for fertilizing purposes or for energy production.

The sludge disinfected during summer can be transported from a wastewater treatment plant to a field or be utilised in landscaping provided relevant safety limits of heavy metal quantities are met. Thus there is no need for temporary storage. Disinfected sludge can also be burned for energy production without any safety risks.

Sludge disinfection with the PACS system also eliminates harmful odors and increases the occupational safety of those working with sludge processing and its further utilisation.

The use of disinfected sludge for soil improvement promotes the transfer of phosphor back to the food chain and simultaneously decreases the need for phosphorous fertilizers.

Sometimes sludge has been disposed of by burying in the ground and this had led to groundwater pollution. The PACS system enables utilising the various biological and economical possibilities of sludge instead.

Benefits

  • Hygienisation enables immediate utilisation by reducing harmful organisms to acceptable levels
  • Decreases transportation costs
  • Decreases the need for composting areas
  • Eliminates the odor problems connected to sludge
  • Increases environmental safety

Further Utilisation Of Disinfected Sludge

  • Immediate use as fertilisers
  • Immediate use for soil improvement
  • Granulation
  • For energy production by burning

The PACS System And Sludge Disinfection

Unique Microbiological Safety

The PACS system enables the selective elimination of hazardous pathogens, such as Legionella, Campylobacteria jejuni, and Escherichia coli, in municipal and industrial water purification processes.

Easily Integrable System

The PACS system has been designed for various targets of use in water purification. It is a comprehensive system that can be easily integrated in operating water plants. It consists of four elements that are data collection sensors, analyzer, monitoring and feed programme, and the PACS liquid.

The PACS system is scalable for daily flow rates from 10,000 to over 1,000,000 cubic metres and the same technical system is suitable for both large and small plants. The problems and needs are evaluated separately for each plant which enables selecting the most suitable solution.

Prior the installation of the PACS system, data concerning the water quality is collected and the target values for purification are set. The real time measuring device feeds the data concerning the water flows to the control device adjusting the amount of the chemical.

The amount of the PACS liquid fed is based on the target value set for purification. Before the purified water leaves the plant it is analysed in order to ensure that the set targets are met and that the optimal operation of the system is maintained.

The control software adjusts the dosage of the liquid in real time on the basis of the data provided by the analyzers. Information from the measurement points and chemical feed are sent both to the monitoring station of the wastewater treatment plant and the PACS remote monitoring station in order to verify the correct operation of the system.
