Innovation in Wastewater Technologies

The wastewater industry is continually updating its technologies as new innovations are discovered and implemented. The wastewater industry was once thought of as a problem that needed solving, but these days, wastewater is treated as a resource to exploit for good, via harnessing its energy.

There are several primary treatment stages in wastewater treatment, including, from basic to advanced, preliminary treatment for screening and grit removal, primary treatment for the removal of light organic matter, secondary treatment to remove excess organic material, and tertiary treatment, which is an optional additional treatment to improve effluent quality.

New wastewater technologies have a focus on integrating with other local services, such as organics composting and energy, while lowering the costs of wastewater treatment through reuse, minimizing pollution of the environment.



Innovations and technologies in the wastewater industry include:

Microbial Fuel Cells

Microbial fuel cells represent a new technology that allows the production of energy from organic matter to treat the wastewater while harvesting its energy. Some processes using this technology can potentially cut treatment process costs by 30-40% while also reducing the amount of leftover sludge by up to 80%.

Membrane Filtration Systems

Membrane technology is becoming increasingly common in wastewater treatment facilities, as the separation process operates without heating, therefore using less energy than conventional thermal separation processes. As membrane systems continue to improve, they are becoming critical to water reclamation systems with the development of these systems leading to the development of advanced water treatment technology.


An emerging technology for the water and wastewater industry, nanotechnology offers potential in the treatment of contaminated surface water, groundwater, and wastewater. This is a growing field, with concepts currently being investigated for higher performing membranes with fewer fouling characteristics.

Natural Treatment Systems

As we get back to the basics and try to work with nature instead of against it, many are implementing natural treatment systems to compliment existing systems. Natural treatment systems can include the capture, retention, and treating of storm water, converting what was originally though of as waste into a usable source of water.

Monitoring & Control Systems

As wastewater technologies improve, so do the technologies to manage and control wastewater systems. There are countless mobile apps to run your SCADA system from anywhere in the world, and there are systems available to optimize any wastewater treatment system using a variety of new and proven technologies. Research on sensor and system control is advancing and new methods to control wastewater treatment are continually introduced.
