wastewater treatment can consume 25 percent or more of the entire city’s electrical bill. Nationwide that’s more than $4 billion annually. According to EPA’s ENERGY STAR program municipalities can reduce energy costs for water and wastewater treatment by as much as 10 percent through cost-effective changes to their operations.
and Challenge through which 24 water and wastewater treatment agencies have set organization-wide energy-saving goals and report their progress once a year to DOE. Partners receive guidance from DOE on setting baselines and tracking energy performance over time. The Superior Energy Performance SEP Program through which seven water and
This step of wastewater treatment takes 60 - 80% of the total energy costs of the sewage treatment plant. With this large chunk of energy costs one can assume that a lot of money can be saved by using the most efficient technology available.
Sewage treatment systems begin treating wastewater by collecting the solid sludge. In a sludge-to-energy system this sludge then undergoes a pretreatment process called thermal hydrolysis to maximize the amount of methane it can produce. Next the treated waste enters an anaerobic digester which finishes breaking it down.

Understanding the energy cost structure of wastewater treatment plants is a relevant topic for plant managers due to the high energy costs and significant saving potentials. Currently energy cost models are generally generated using logarithmic exponential or linear functions that could produce not accurate results when the relationship between variables is highly complex and non-linear.

Considered an increasingly critical topic of global concern wastewater treatment is something industrial manufacturing operations can address with any number of existing efficient and effective systems. Companies can employ many different strategies to help themselves go beyond mere compliance and begin the process of improving water quality.

The microfilter designed for all the industrial sectors in which the material recovery and the water reuse is fundamental. Primescreen maximum efficiency in the primary treatment A completely self-cleaning conical disk filtration system that allows compact footprint and immediate energy savings in the primary treatment .
The use of gray-water recycling systems in new commercial buildings offers a method of saving water and reducing total sewage volumes. These systems filter and chlorinate drainage from tubs and sinks and reuse the water for nonpotable purposes e.g. flushing toilets and urinals .

The amount of electricity created is not enough to say power a city but it is in theory enough to help to offset the substantial amount of energy used in a typical U.S. water treatment plant.
Treating water to the right standard and safely dealing with wastewater are primary concerns for water and wastewater treatment plants. But such services need energy and this comes at a price.
This wastewater is an untapped resource. The challenge arises with transporting wastewater to treatment facilities then bringing treated water and sewage sludge in turn to wherever it’s useful. These are energy- and infrastructure-intensive processes.
The Future of Energy Efficiency in Wastewater Treatment Wastewater treatment is a necessary industry throughout the developed world. People are constantly generating waste and to keep it from overwhelming the surface of the planet that waste needs to be treated.
