Compressed air is used in a wide range of applications in the wastewater treatment industry. In fact, it is such a critical part of the process that compressed air pumps and blowers consume as much as 80% of a plant’s energy usage, according to the U.S. Environmental Protection Agency and the U.S. Department of Energy.
Sewage comes to wastewater treatment plants from a variety of sources, including residential sources like kitchens and bathrooms, commercial buildings and stormwater flowing off streets and buildings. Wastewater treatment facilities are operated by municipal authorities and private companies, usually major industrial plants or utilities.
In most plants, wastewater is treated in three stages:
Compressed air is used throughout the wastewater treatment process in all three stages. Specific tasks include the following:
Aeration and oxidation are two critical processes compressed air supports in the wastewater treatment process.
Compressed air helps remove contaminants, while wastewater is in treatment tanks or lagoons.
Low-pressure compressed air (like our KRSL rotary screw low-pressure series) is often all that is needed for many of these applications. As a result, Compressed Air Best Practices encourages plants to consider use of blowers and electric pumps to reduce energy costs and improve productivity. However, we have found that many plant operators choose rotary screw air compressors to reduce the noise level in their plants.
Our KRSL low-pressure series was designed specifically for low-pressure applications like many of the wastewater uses mentioned above. It has our breakthrough variable discharge port that helps the KRSL delivery high efficiency, performance, sustainability and energy savings.
The most effective use of rotary screw air compressors is in pneumatic controls.
Pneumatic controls are widely used in wastewater treatment plants because they offer several advantages over other power sources, including the following:
Kaishan USA provides wastewater treatment operations with compression systems that thrive in heavy-duty environments. Our air compressors are built with exceptional features like stainless steel tubing and offer superior reliability, ease of maintenance and optimized energy efficiency to reduce overall lifecycle costs. Kaishan compressors keep operational costs down while eliminating costly downtime.
Our KRSP premium rotary screw air compressors are used extensively in the wastewater treatment industry.
Rotary screw air compressors appear in so many applications because of a wide range of advantages, including the following:
Kaishan’s KRSP and KRSP2 rotary screw compressors are backed by an unmatched lifetime airend warranty, thanks to their reliability, efficiency and long life.
Some manufacturers promote the use of oil-free air compressors for wastewater treatment applications. However, we find very few oil-free models in plants. First, because of their increased acquisition and operating costs. And second, because the wastewater treatment process itself can easily remove any airborne oil that lands in the wastewater.
Kaishan USA works with a nationwide network of independent distributors, who can provide on-site help and consultation as needed. These factory-trained air compression experts have an investment in their local communities and can help you optimize your compressed air system.
