Powerful and environmentally-friendly disinfection and oxidation
Ozone systems OZONFILT® OZVb are pressurised systems in which compressed air is fed into the ozone generator.
Ozone is generated from the oxygen content of the surrounding air, via a compressor and is inducted into the process based on demand. Ozone can now be generated in values of up to 20 g/Nm3, safely and reliably in the many demanding environments and plant room locations globally. Ozoneconcentrations within the water to be treated with values of between 3 and 12 ppm can be achieved using our coordinated mixing equipment with an efficiency of up to 95%.
Your benefits
- Safe and seamless operation through continuous monitoring of all relevant operating data
- Simple, safe and reliable operation with process visualisation, thanks to large, colour and clear 4.3" touch panel
- Compact system with integral air treatment
- Turnkey complete system with perfectly coordinated mixing device including back pressure valve, vacuum breaker and static mixer
- Direct injection without injector system for up to 4 bar back pressure
- Low maintenance and operating costs, thanks to maintenance-free generator concept and virtually infinite service life
Field of application
-
Potable water supply: Oxidation of iron, manganese and arsenic, refinement and taste enhancement and disinfection
-
Waste water treatment: Degradation / reduction of COD and micro-contaminants, reduction of sewage sludge
-
Food and beverage industry: Oxidation of iron and manganese, disinfection of table water and rinser water
-
Swimming pools: Degradation of disinfection by-products, reliable microbiological barrier and production of crystal-clear water, thanks to its micro-flocculating effect
-
Industry: Legionella prevention and disinfection of cooling water
Technical Details
- 4 different sizes depending on the capacity range
- Compact mounting in a painted steel cabinet
- Special dielectric with outstanding cooling performance: in spite of the low cooling water consumption, heat is quickly and efficiently discharged before the ozone produced can decompose due to excessive heat
- Integrated air treatment based on a pressure swing dryer with adjustable throttle valve and analogue flow measurement and pressure monitoring
- Continuous analogue pressure measurement in the ozone generator with automatic capacity adjustment to compensate for pressure fluctuations
- Cooling water system with automatic shut-off valve, adjustment valve and monitoring device via flow and temperature sensor
- Gas-tight diaphragm valve at the ozone outlet
- PLC (Programmable Logic Controller) control with operating data recorded on an SD card
- Simple, safe and reliable operation with process visualisation, thanks to large, colour and clear 4.3" touch panel
- Contact inputs for external On/Off switching, gas detector connector, external fault alert, flow control
- Analogue input 4-20 mA for power control depending on the measured value combined with external measuring and control technology
- Contact outputs for collective malfunction alert, warning and operation
- Wide range of communication interfaces for connection to higher-level controls or for remote monitoring (LAN web server, PROFIBUS® DP, PROFINET®, Modbus TCP or RTU)
- Evaluation and analysis program for the simple and fast visualisation of operating data on a PC
Options
- Stainless steel control cabinet
- Pressure controller with filter unit at the compressed air input
- Different designs of ready-wired installed mixing unit up to complete equipment including back pressure valve, vacuum breaker and integral static mixer
- Air conditioning: The system can be equipped with integral air conditioning with ambient temperatures above 40 °C
- Control of a cooling water heat exchanger
- Integration of a dew point sensor to monitor the quality of compressed air
