What to call a wastewater treatment plant?
No one wants to have his or her home near a wastewater treatment plant, regardless of how well the plant is designed and is aesthetically acceptable. But calling it by a different name could mitigate that concern. Consider naming it a water reclamation plant, water conservation plant, water recycling plant or water factory instead. This could mitigate, if not eliminate, that concern. Sometimes, it could simply be a perception issue, which can be addressed by giving the facility a different catchy name. Most plants in the U.S. today are renaming their facilities with those listed earlier. A plant in Orange County, California, for instance named its plant Water Factory 21.
Why should citizens be given tours of plants?
Concerned citizens should be given tours of these plants by members of the PR team so that they are comfortable with the technologies being proposed. Their comments should be heard and addressed in the design and layout of the plant. In other words, these citizens should become a part of the selling team that promotes the need, location, design and other elements of the plant to other citizens, interested groups or skeptics in the community, who were not able to attend tours.
How to get rid of odors on plants?
Another remedy, which has been used at some plants, is to use a masking agent, often a fragrant chemical or a perfume, that is pumped via a small diameter piping system - usually half inch to 1 inch diameter in size – often attached to the fence or the boundary wall, around the periphery of the entire property or only around a portion of the property which faces the concerned neighbors. The perfume is pumped and sprayed through suitably designed and spaced nozzles when the odors are prominent – say on windy and hot days.
How to confine, capture and transport odors to the site of the scrubber?
That is easily done by enclosing and/or covering the odor-causing processes, withdrawing the foul air by fans, and transporting it to the scrubbers in high-density polyethylene ducts, which are laid underground or aboveground.
Did the citizens believe in old plants?
This is what the citizens have always believed, and they probably are right. They have likely visited some old plant designed at a time when either the odor was not an issue (remote location perhaps) or the technologies to confine and treat odors were not available.
Is membrane bioreactor better than activated sludge?
For example, membrane bioreactors (MBR), by virtue of their smaller footprint, may be a better treatment process than conventional activated sludge. In small size plants, with MBRs, it may be possible to eliminate primary clarifiers, which often generate more odors than other processes at the plant.

Work clothes should not be worn home.
How to reduce electricity consumption in wastewater treatment plant?
You could optimize aeration by upgrading the blowers and air distribution system components with variable frequency drives and installing dissolved oxygen control systems, which can decrease the blowers’ electricity consumption. If you have aging blowers, consider replacing them with a single high-efficiency turbo blower, which has a wide range of operation and can be controlled based on dissolved oxygen. Do you have an aging diffuser system? If so, replacing the diffuser grid with new fine-pore or ultra-fine-pore diffusers will improve oxygen transfer efficiency and reduce the amount of air needed for treatment.

Why are pump stations important?
A significant portion of a utility’s energy usage is attributed to one or more pump stations used in virtually every community’s collection system. Older pumps were typically designed to operate at a single speed and on/off cycling. Today’s pump/motor/drive combinations are more efficient over a wider range of flows. Upgrading older pumps can produce long-lasting operation and maintenance savings. Inexpensive and more reliable variable frequency drives can also be used to match pump speeds to flow rates, further reducing energy needs.
