Thermal Mass Savings

In wastewater treatment facilities, the cost of supplying compressed air flow to aeration basins easily can be one of the facility’s largest energy expenses. The figures most often cited are that 40% to 50% of a wastewater plant’s total energy usage can be attributed to the aeration process. The cost to produce this compressed air continues to increase proportionally with energy cost increases.

Effective Aeration Basin Air Flow Monitoring

The aeration process requires large amounts of compressed air, and the energy cost of producing the compressed air is a big expense. The efficiency of the entire aeration process greatly depends on the management of microorganism growth, which is directly dependent on controlling the amount of air that is supplied to the basins.

Accurate airflow measurement and control of compressed air is essential to the entire wastewater treatment process—both in terms of quality results and cost control.

Attention to Aeration

A fast-growing city in the arid desert of the western U.S. recently addressed the need to expand its municipal service for new residents and subdivisions. In recent years, the city's residential demand for wastewater treatment tripled from less than 1 million gal per day (mgd) to more than 1.5 mgd. In planning for the wastewater treatment plant's (WWTP) expanded capabilities, the city's water engineers identified minimizing aeration basin compressed-air energy costs as a goal.

Protect Your Pump and Keep it Longer

Avoid pump failures with these care and prevention tips for liquid pumpsIn today’s complex and frequently rugged process plant environments, liquid pumps are often overworked and underprotected from adverse operating conditions. Many pumps run nearly nonstop 24 hours a day over multiple shifts. Poor operating conditions can reduce pump performance, require extra maintenance, shorten pumps’ lives and increase operating costs.
