Kaeser’s custom engineered solutions are compressed air and vacuum systems built to specification for the most demanding and challenging installations. Whether in custom enclosures or modified ISO shipping containers, these complete systems are designed for exceptional reliability, simple maintenance, and superior energy efficiency no matter what the installation limitations may be. They eliminate space, weather, and accessibility constraints and can significantly reduce construction, installation, and operating costs.
Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.
Energy is the single highest operating cost in a wastewater treatment plant. More specifically, the energy to operate blowers for aeration is the single highest energy consumer.
Kaeser has been designing and manufacturing superior industrial machinery since 1919. With nearly a century of manufacturing experience, we pride ourselves on upholding our traditions of quality and craftsmanship. Our reputation for reliability, energy efficiency, and excellent service has helped us grow into a global leader in blower and compressed air technology.
Kaeser Com-paK blower systems offer the best combination of quality construction, reliable performance, and ease of ownership. The Com-paK design features a full scope of supply that is unmatched in the industry. Our complete package design minimizes time and money spent on engineering, procurement, documentation, and installation. Com-paK units arrive fully assembled and ready to operate.
Written by Kaeser’s system experts, this whitepaper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.
Kaeser’s complete line of air system products includes industrial electric and portable gasoline and diesel rotary screw compressors with the highly efficient Sigma Profile™, rotary lobe and screw blowers, compressed air boosters, and vacuum packages.
Kaeser Compressors’ Blower System Installation Guide: Layout Considerations for a Reliable, Energy Efficient, and Safe Blower System provides essential tips for planning and installing a blower system. Written by Kaeser’s blower and engineering experts, this e-book includes installation diagrams, information on piping, ventilation, controls as well as additional resources for ongoing energy management.
Kaeser screw blowers use up to 35 percent less energy than conventional rotary blowers and even achieve significant energy savings compared to currently available screw blowers.
The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.
The next big thing is here and it’s the Industrial Internet of Things (IIoT). With pundits waxing philosophical on this big breakthrough, it’s hard to cut through the noise and understand what the IIoT actually is and how it applies to individual plants. I offer the following as a definition. The IIoT means collecting, interpreting, and applying data to actively improve processes or operations. To understand how the IIoT applies to a wastewater treatment plant, look no further than your front yard.
This product brochure covers Kaeser’s line of DBS, EBS, and FBS series rotary screw blowers. These screw blower systems feature the world-renowned Sigma Profile™ and are specifically designed for even the most demanding blower applications.
System controls are critical to a wastewater blower system. Without them, a system with multiple blowers operating on their individual controls will run more than necessary and result in wasted energy. Maintenance costs increase and worst of all: process performance suffers.
As part of her tour marking the opening of this year’s Hannover Messe, German Chancellor Angela Merkel and Polish Prime Minister Beata Szydlo paid a visit to Kaeser Kompressoren’s trade show booth. Naturally, Kaeser was delighted to welcome Chancellor Merkel and Prime Minister Szydlo. For her part, the Chancellor was enthusiastic about the power of innovation demonstrated by the Coburg-based compressed air system provider.
Wastewater treatment plants provide a critical service to our communities. WWTP systems operate continuously and equipment must be completely reliable and sustainable. Kaeser delivers exceptional air system solutions for wastewater treatment operations that are engineered for long life and continuous energy savings.
In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality. An increasingly popular approach includes installing a variable frequency drive (VFD) to constantly adjust the amount of air injected into the process to control dissolved oxygen, NH4, and/or NO3 in the wastewater treatment.
When it comes to the costs of running a wastewater treatment plant, the conversation tends to begin and end with blowers. These machines are a staple in wastewater operations, gobbling up energy and running up the power bill as they function, so it’s worth taking the time to make the right investment.
Kaeser Compressors has revolutionized compressed air controls with the sigma Control2.
Wastewater managers are always under pressure to reduce costs. Lowering the electric bill — which also saves precious resources — is a high priority.
At a wastewater plant, aeration is king. As a central part of the treatment process and the major contributor to energy costs, operators are constantly looking for ways to improve the aeration stage by revamping, replacing, or modifying the blowers and their packaging.
