Aeration and bubbles in Wastewater Treatment Wastewater aeration is the process of adding air into wastewater to allow aerobic bio-degradation of the pollutant components. It is an integral part of most biological wastewater treatment systems. Unlike chemical treatment which uses chemicals to react and stabilize contaminants in the wastewater stream, biological treatment uses microorganisms that occur naturally in wastewater to degrade wastewater contaminants.
In this blog we have outlined the four main signs that indicate it's time to upgrade. There are a whole variety of reasons why operators and managers come to the decision that its time to upgrade their wastewater treatment plants. Understanding the underlying drivers is of importance for consultants and designers when considering how best to utilise existing assets and achieve the desire outcomes.
Achieving a more energy efficient wastewater treatment plant has never been so important. Issues around energy consumption are of growing importance in the context of higher energy and production costs, emissions and a changing climate. Energy for aeration comprises a significant portion (60% average) of the operating costs of a wastewater treatment plant. According to the United Nations, globally it is estimated that implementing energy efficiency measures would account for more than 65% of energy-related emissions savings up to 2030. The water industry is one of the largest industrial users of energy with an estimated 2% of total global electricity consumption used for the aeration of wastewater. It is therefore in the best interest of the environment and the economics of wastewater treatment plants, for operators to find efficiencies in energy use.
Emerging Economies Have a Unique Opportunity to Leapfrog with WasteWater Infrastructure Innovation There is a tendency to want to mirror or mimic what other successful economies have done when you are looking for templates to build, or improve, a nations infrastructure. This is a highly justifiable rationale, after all if it has worked once it is likely to work again. But nowadays emerging economies have become more savvy and are more open than ever to the opportunity of leapfrogging.
Energy Neutral Wastewater Treatment Plant Concept Even though the concept of an energy neutral wastewater treatment plant is a relatively new one - there are a large number of innovative technologies and smart approaches which are creating a template for energy neutrality for wastewater treatment plants of the future.
