The recovery of natural waters is a long-term process that helps the natural waters to cope with oxygen-free spaces. Bacteria and microbes that are harmful for the environment and human health prosper in oxygen-free spaces and promote the pollution of water system.
The PACS system can be used for dosing grains or liquid in a targeted manner in oxygen-free vacuums and basins. The grains dissolve in six months and release oxygen slowly. The operation can be repeated at intervals of six months, but the primary goal should be to prevent pollution, i.e. to ensure efficient purification and post-disinfection of wastewater.
The PAC–Solution develops technology, which enables boosting water circulation, destroying microbes that are dangerous to health, and creating more sustainable and energy-efficient solutions. The PACS system has been created to fulfil the need for safe, cost-effective, and fast water purification.
John Nurminen Ltd. is a private equity investor and partner in the PAC-Solution that provides a unique wastewater and utility water purification solution and invests in internalization of the company.
The company promotes sustainable development and develops individually tailored and responsible complete solutions for various environmental problems and improves the level of water safety at a global level.
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.
