A Guide to Blowers

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.

Learn the differences in blower design and how to choose the right one for a given treatment plant.

Industrial Compressor or Electric Heater?
See your compressors in a new light to unlock major energy savings and cost rewards

More and more industrial compressed air users are embracing a systems approach to energy efficiency. Gone are the days of simply comparing the electrical efficiency of compressors and buying the one with the lowest input energy. Smart operators are looking beyond individual components. They are beginning to understand that true efficiency is more than the sum of the system's parts -- it's how everything works together as a whole.

Blower System Integration for Wastewater Aeration

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 plays a vital role.

Blower air is an indispensable part of biological wastewater treatment plant (WWTP) processes. Integration -- on the blower package level as well as the system level -- is key to maximizing energy efficiency and ensuring that this critical service is readily available for the communities the WWPT serves.

Kings of the Road

Kaeser Compressors has teamed up with West Coast Customs for a technology partnership that will get your motor running! Many of us were first introduced to West Coast Customs when it served as the back drop for MTV’s wildly popular series Pimp My Ride. This success lent itself to their own show that aired on different networks. Kaeser first appeared on the “DC Tundra” episode and continued through the third season and into reruns. Currently, they are getting ready to launch a brand new show with even bigger builds on Fox Sports.

Go With the Flow

Dallas-based American Leather has had great success with using Kaeser’s rotary lobe blowers for vacuum hold down on router tables. This article details how American Leather experienced issues with their hold down including their router tables not keeping the plywood sheets in place after significant portions were cut off which created down time, inaccurate cuts and excessive scrap material.  Kaeser sales representatives worked with the company to find a solution that helped fix the issues.

Maximizing Compressed Air Energy

A plant or manufacturing facility’s need for compressed air is undeniable.   Not only is it necessary for the functioning of tools, but it is also essential in the processing of products that require clean, high quality air as part of its production cycle.   Not all compressors are created equal, nor do all plants’ needs follow specific guidelines.   Choosing the right system for your plant’s operational needs is vital, often determining productivity, customer service and quality levels.

New Blower Packages Improve Dewatering System Performance

Dewatering processes, such as carpet dewatering in the textile industry and pulp dewatering in the paper industry, are excellent opportunities for incorporating current rotary-lobe blower technology, and improving system efficiency and lowering operating costs. A rotary-lobe, positive-displacement blower setup for vacuum operation and coupled with a moisture separator before the blower provides a new dewatering method that is more energy efficient and significantly more controllable.

Reinventing the Industrial Blower

Today, industrial blowers are the workhorses of the process industry.  These high volume, low pressure air producers are being used by the hundreds in some operations for a variety of applications from material handling to aeration.  However, despite the prevalence of industrial blowers there is a downside: blowers can create noise levels that rival jet engines if not properly designed or enclosed.  Therefore, finding an industrial blower package that has been properly designed and optimized to reduce sound output is necessary to prevent dangerous ambient noise levels and sound vibrations that can damage other equipment throughout the system.

Tailor-made air supplies for PET bottle production

It's immediately obvious from a glance in the beverages section of any supermarket – the containers and bottles of polyethylene terephthalate, better known as PET, are competing strongly with conventional glass containers and bottles. And there's a good reason; PET offers both the beverage industry and the consumer immense advantages. Compressed air plays a central role in the production of modern packaging mediums. In this particular field of operations, tailor-made system solutions can increase efficiency significantly.

Zurich to Thalwil, An Example of Modern Tunneling Technique

Swiss Railways have laid a parallel dual railway line between Zurich and Thalwil to relieve the heavy traffic load on the lakeside section of this route. The new line, opened for passenger and goods trains in 2003, passes through a tunnel for 9.4 of it's total 10.7 km length under the Allmend Brunau region. The geological structure through which the tunnel was driven presents a stiff challenge in which compressed air played a major role.

Piesau Glassworks Opts for Efficient Air Technology. Traditional glassworks successful on the open market

Entry into the open market proved to be a successful venture for the German Piesau Glassworks in Thuringia, turning them into a competitive international presence. Whereas the smelting furnaces run on electricity and gas, compressed air is the main energy medium for the processing machines in which glass vessels are blown. The article describes the efficiency of the compressed air and vacuum stations, which are under the control and supervision of a KAESER VESIS master controller. With regard to overall economy, this equipment offers a decisive advantage in that the optimized performance and utilization of the compressors as well as improved ventilation will bring the user a shorter payback time.

Next Summer Will Surely Come! How to avoid overheating problems in compressed air installations.

Soaring summer temperatures bring sweat to the brows of many production managers whose plant relies on compressed air being delivered by equipment not adequately designed and installed for realistic year-round conditions. The article deals with the cooling aspect of compressor and dryer design and installation. The compressor room itself as well as the compressors in it must be properly ventilated with provision for inlet and exhaust air. Heat of compression has to be taken away and should ideally put to some useful purpose via a heat recovery system. The air dryer downstream of the compressor has to be designed to cope with high ambient and high air inlet temperatures. All these criteria should be taken into account for optimum configuration of an air system that can be relied on.
