Industrial Utility Efficiency

Blower Systems

Aerobic digestion is a common treatment technology used at small-to medium-sized wastewater treatment plants for the treatment of waste activated sludge (WAS). The objective of aerobic digestion is to treat the sludge for disposal, and for those trying to meet Class B biosolids, further reduce volatile solids (VS) and pathogens to ensure the sludge is suitable for land application.

APG-Neuros Retrofits San Bruno Aeration System with New Turbo Blowers

A facility audit examined the plant electrical energy consumption to find ideas to reduce plant energy use while meeting the process demand. Based on discussions with plant staff and a brief review of the process, it was decided to focus the effort on reducing the electrical energy required to provide aeration air to the secondary activated sludge process. The aeration air blowers were the largest consumers of electrical power in the plant and significantly less efficient than the newer blowers that have been introduced to the market place in the recent years.

How To Select The Most Effective Blower Technology for Wastewater Applications

This guide explains three blower technologies and,using examples from actual wastewater plants, describes the most effective technology for particular applications and why. Of course there is no substitute for a consultation specific to your application; however, the guide can help raise the right questions and ensure a productive vendor and technology evaluation process.

Pneumatic Conveying Energy Assessment Saves $321,000

The plant air system consists of eight, single-stage, lubricated, Sullair rotary screw compressors. All units are in good working order.  Units 2, 3, 4 and 7 are water-cooled and units 6, 8, 9, 10 and 11 are air-cooled. The main plant air system has two primary compressed air dryers, a Thompson Gordon model TG 2000 refrigerated dryer, and a Sullair model SAR 1350 heatless desiccant dryer.  Both units are working according to their design. The TG 2000 uses approximately 11.2 kW and is a non-cycling type unit, and the SAR 1350 uses approximately 200 cfm of purge air to regenerate the wet tower. 

Screw Blowers and Membrane Bioreactor Treat Wastewater at a Bottling Plant

The right ingredients and processes are essential for manufacturing flavorful beverages that contribute to the company’s bottom line. But what happens to all those other “ingredients” that aren’t part of the recipe? Cleaning up those unwanted ingredients from bottling plant wastewater can consume large amounts energy, time and money—and become a distraction from the company’s primary goal of manufacturing beverages.

Improved Aeration Efficiency through Design and Control

With the recent and future increases of the cost of energy, operating a wastewater treatment plant (WWTP) as efficiently as possible has become one of the most important factors that operators and managers are facing today. The implementation of a properly designed aeration control system has been reported by the United Sates Environmental Protection Agency to reduce aeration energy by 25 to 40 percent.

Furniture Maker Goes with Tri-Lobe Blowers

A large custom leather furniture manufacturer switches from rotary screw vacuum pumps to blowers for CNC router table hold down, and saves big on electricity, maintenance expenses and floor space.

A View From India: Pneumatic Conveying of Bulk Materials

In thermal power stations, nuclear plants, and chemical and industrial plants, different types of bulk materials are used. The materials exist in different forms including lump, powder, granules, chips, and pallets. These bulk materials, in their different forms, require efficient and reliable material handling systems.

Water Treatment Plant Receives $1.7 million Energy Grant

A new cogeneration system installed at the Budd Inlet Treatment Plant by the LOTT (Lacey, Olympia, Tumwater, and Thurston County) Clean Water Alliance late last year uses treatment by-products as fuel to generate electricity and heat energy. This renewable energy system, combined with an aeration blower retrofit currently underway at the Budd Inlet Treatment Plant, is expected to save LOTT more than $228,000 per year in utility costs.
