Oxelia system for circulating water of use or sensitive water.
The system allows you to effectively destroy the following pollutants in the source water:
- Endocrine-disrupting compounds found in pharmaceutical products;
- Medicines;
- Pesticides and herbicides
- Industrial chemical products, in particular. NDMA;
- Chemical compounds produce changes in taste and smell, geochanges, 2-MIB.
Features of the system:
- Multi-barrier system for preparation of drinking water. Disinfection is carried out and the most problematic organic contaminants, precursors of taste and smell changes, as well as pathogens are destroyed.
- Increases the output of purified water, minimizes losses during backwashing.
- Disinfection by-products are eliminated
- Purified water has high biostability, which prevents the re-growth of bacteria in the distribution network.
- The need for chlorine to maintain its residual levels decreases, while reducing the formation of chlorine derivatives.
- Lower capital costs compared to other treatment systems.
The Oxelia system uses strong oxidizing agents to destroy long chains of organic pollutants, which leads to the loss of their toxic properties and prevents their transformation into biodegradable organic substances, while saturating the water with oxygen. At the same time, natural microorganisms on the filter with biologically active carbon absorb partially oxidized organic compounds, completely removing them from the water. Thus, at the stage of filtration through biologically active carbon (BAC), natural microorganisms attach to the granular activated carbon of the filter load, turning into BAC.
Microorganisms assimilate partially oxidized organic compounds thanks to dissolved oxygen to reduce the concentration of total organic carbon. As a result, the output is purified, disinfected, biologically stable water with a minimum content of pollutants.
This principle is based on the fact that GAU gives excellent results as a biologically activated filter material in combination with oxidation. BAU-type filtration can reduce the level of oxidized organic compounds to a minimum level, even below the detection limit. The Oxelia system also significantly extends the life of the DAU, reducing the total operating costs, as well as the costs of replacement and regeneration of the DAU, and also allows to completely abandon the use of PAHs.
The Oxelia system can be configured for stronger oxidation, which is determined by the degree of pollution of the source water using combinations: only ozone; ozone + hydrogen peroxide or UV + hydrogen peroxide, namely:
- Ozonation + BAU – used for constant control of taste and smell, as well as for the removal of traces of organic pollutants, disinfection and removal of disinfection and oxidation by-products.
- UV Irradiation + Hydrogen Peroxide (UV-Based AOR System) + BAU - Optimal for UV photolytic chemical compounds such as NDMA, permanent disinfection and seasonal deodorization.
- Ozonation + Hydrogen peroxide (AOR system based on ozonolysis) + BAC – to maintain taste and smell indicators, disinfection, phytoplankton, spills of chemical compounds, removal of traces of organic compounds and removal of disinfection and oxidation by-products, including bromate concentration control.
Since even traces of organic compounds are removed by microorganisms on the biologically active filter load, the purified water is biologically stable, which reduces the formation of chlorination byproducts such as trihalomethanes (THMs).
In the Oxelia system, modern online sensors are used to monitor the concentrations of incoming organic compounds, the doses of oxidants, the degree of filtration and the quality of purified water. Integrated analytics and feedback control provide real-time adjustments to chemical dosing or UV radiation levels in response to fluctuations in water quality or flow rate, ensuring optimal operational efficiency.
In real time:
- An advanced on-line sensor network monitors inlet and outlet water parameters to improve process reliability and maintain cleaning continuity.
- Oxelia's centralized monitoring and control system uses a single PLC and interface for ease of operation.
- Integrated controls allow for real-time adjustment of ozone or UV dosage in response to changes in flow rate and water quality for optimized operation and efficiency.
- Controls combine oxidation and filtration operations, sequence of backwash operations, and dosage control to ensure biofilter performance to optimize turbidity, OOR, and removal of oxidation and disinfection byproducts.
