How Can Wastewater Treatment Become More Energy Efficient and Sustainable?

Energy Efficiency of Wastewater Treatment - Reducing Wastewater Treatment Energy Use.

Facilities responsible for processing, storing, and moving water use energy in different ways depending on a number of different variables. Wastewater treatment plants, in particular, use a significant amount of energy for these processes and activities. Wastewater transport distances and source water depths are just a couple of variables that can impact a facility's overall energy use. Improving efficiency will help the facilities control their operational expenses in terms of sustainability.

Efficient Energy Consumption in Wastewater Treatment?

This is dependent upon the design and operation of the facility. Is wastewater treatment energy efficient?, It can be more efficient when plants use suitable equipment, monitor performance, and reduce unnecessary energy consumption. For instance, effective pumps use less power to transfer water, while the use of screening equipment eliminates any possible clogging and wear of the equipment by solids.

Equipment Choices That Support Sustainability

Pumps are an important part of treatment operations. Lakeside Equipment Corporation explains that enclosed screw pumps can offer efficiency advantages in certain applications. The proper selection of a pump according to the flow and configuration of a particular plant can lead to decreased energy and maintenance costs.
Screening processes also serve an important purpose. These processes filter out any solids, grit, and other unwanted elements prior to creating issues within later phases of the treatment process. The purpose of aerators is to supply oxygen to the sewage water so that the natural treatment process functions effectively. The SCADA software will aid the operator to monitor the flow rate of water and regulate the speed of the pumps.

Small Things Make Big Difference in Energy Efficient Operations

Even small modifications can be effective for operational processes. Facilities can opt for efficient lights, plug leaks and even consider alternative energy sources like solar or wind energy. It is also helpful to monitor the energy consumption to notice any increase and address the problem before it causes unnecessary losses.

Improving the sustainability of waste water treatment need not necessarily mean replacing existing equipment. Selection of proper equipment, regular testing of performance and proper maintenance of equipment can aid in smooth operation and better control of operating expenses and energy usage.
