Treating drinking water: How to do it safely and efficiently
Water is valuable. Our consumption of water is rising worldwide while groundwater levels continue to decline. How can you treat water efficiently, productively and in a way that assures future viability? The water industry employs automated and digital concepts. At process level, Bürkert offers support through automated water treatment solutions.
The key objectives of water treatment:
Reliable water quality
Economical use of the water resources
Treating water: More performance, less energy
Do you want to automate your water treatment process? Do you want to use intelligent control concepts and measurement methods to save energy? Discover how digitised input and output control can reduce your energy consumption significantly.
When handling and treating drinking and process water, you remove unwanted suspended solids and bacteria from the water. Wanted substances – such as additives and dissolved elements – remain or are added. Key sub-areas:
Your challenge: Treating water productively to the highest possible quality – to do so, you need:
An integrated, lean design
High-performance and energy-saving components
Sub-areas: Media filtration or ion exchanger or Diaphragm filtration
Valve island: Process automation with pneumatic actuator and control
technology: Valve islands control the individual flaps, armatures and valves
but sometimes also sensors.
How can I automate process and drinking water treatment?
Be it process or drinking water: The requirements that apply to the construction and operation of water treatment plants are increasing. They can, however, be met when using the right technology. Automation can be achieved in various ways: Distributed (with and without a control cabinet) or also decentralised. Which is best for your plant? We present the advantages of the concepts and help you find the best solution for your plant.
“Short distances”: Automation is distributed across the process.
Mode of operating:
Depending on your requirements, the distributed automation concept can be implemented in your plant with or without a control cabinet. When using control cabinets, automation can be achieved in an efficient and economical manner with AirLINE Quick, as valve islands can be placed directly on the control cabinet wall or floor. This results in a reduction of lines and cables, which in turn reduces the amount of compressed air required.
If you choose a variant without a control cabinet, it is possible to use valve islands with a high degree of protection. The advantage in this case is that you are close to the process and require fewer additional cable trays, hoses and lines.
Advantages of distributed automation:
✓ Fast installation and reliable processes thanks to short distances and flexible, space-saving installation ✓ Reduced consumption of compressed air and energy makes your system faster, more economical and more efficient ✓ Simple monitoring and cleaning thanks to robust process units with a high concentration of valves ✓ Fewer hoses, lines and cable trays thanks to close proximity to the treatment process
“Lean and fast switching”: The automation is located directly on the valve.
Mode of operating:
Each process valve is controlled individually and supplied via its own smart control head. With the help of the control heads and the corresponding digital communication options, standard valves are turned into intelligent field devices. Process valves signal their switching status via LEDs, thus providing an excellent overview of the entire process.
Advantages of decentralised automation:
✓ Simple, on-site process monitoring eliminates troubleshooting and guarantees availability of the water treatment plant ✓ Intelligent, fast-switching valve systems are particularly flexible, clearly arranged and reliable ✓ Easier start-up, maintenance and expansion due to individual solutions ✓ Proximity to the treatment process reduces the need for compressed air, energy, pneumatic hoses, lines and cable trays
From the sensor to the electrical cabinet: Precise automation of your water treatment process
Which type of automation is best suited to your application? Together we analyse your needs and provide help and advice with the concept idea. From the valve and sensor to the fully configured electrical cabinet, the Bürkert modular system contains everything you need for an all-round solution tailored to your specific needs.
Four reasons for automating your water treatment process
Intelligent communication with standardised interface
Automation should make your processes simpler and more efficient. And this starts with the communication: The fieldbus module Type ME43 or the industrial ethernet gateway Type ME63 functions as a standardised interface for the devices. It transfers the communication to common industry standards. Good to know: The technology minimises planning and installation effort, material usage and the risk of errors.
the added amount of liquids and chemicals, e.g. chlorine.
ME44 I/O moduleThe
graphical programming f(x) of the ME44 I/O module makes it possible to
adapt water treatment processes locally and individually – without tampering
with the actual process control system.
The valve island switches
the pneumatic process valves, signals switching statuses and carries out
The configuration software “Bürkert Communicator”
enables the configuration, diagnosis and parameterisation of EDIP devices
and networks. Cyclical values can be identified easily and displayed graphically.
How much space and costs do you really save when treating water with a Bürkert automation solution optimised to your needs?
The calculation example compares installation of a valve island Type 8652 with AirLINE Quick to installation on a standard rail inside a stainless steel electrical cabinet:
Installation on a standard rail Installation with AirLINE Quick
The savings potential: Valve islands with AirLINE Quick ensure fast, seamless installation and start-up. They are located directly on the wall or on the floor of the electrical cabinet – this helps to reduce the number of compressed air hoses and the cabinet volume. Your savings in figures: 27,720 cm³ of space and €354.49 in costs.
