Legislation puts pressure on legacy WWTP’s Some of the harshest wastewaters across the globe may be closer to home than you think. Thankfully, over the past few decades the world population has turned a corner in terms of increased environmental awareness and the need for a sustainable future. Formal environmental protection agencies and groups have been established, regionally and globally, to both protect ourselves and our natural resources. One area that has gained considerable attention is wastewater. Effluent discharges, especially those from companies into our streams, lakes and rivers are now under scrutiny. Though it has taken tens of years to arrive at this welcomed environmental awareness juncture, and no doubt will take considerably more years from now to engrain in our mindset, the reality is that this first step on this journey has been the easy one. Looking after our planet in a sustainable manner, though possible, is not easy. Step one, saying “we will take action” is always easy… The hard part comes after the decision to take action has been made. Solutions are then sought and when they are found they must be implemented. Not so easy as step one.
4 Signs You Are Ready to Upgrade Your Wastewater Treatment Plant 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.
5 Considerations When Managing An Industrial Wastewater Treatment Plant Effective WasteWater Treatment Wastewater treatment operation and maintenance is a complex process - one that is essential for the successful treatment of wastewater before it is discharged into the environment. Industrial wastewater is a by-product of industrial processes, and is separate from domestic sources of wastewater.
Time to Get Serious About Wastewater Treatment Why WasteWater Treatment Innovations Like MABR Can Transform Our Water According to the fourth World Water Development Report, only 20% of global wastewater is treated (UNESCO, 2012). The vast majority of wastewater is discharged directly into the environment without any form of treatment. Worldwide wastewater treatment is clearly inadequate and failing both society and the environment. Urban populations are projected to nearly double in the next 40 years, from 3.4 billion to over 6 billion people - but already most cities fail to provide adequate wastewater management due to absent, inadequate or aging sewage infrastructure (World Water Council, 2012). According to a recent UN-Water Analytical Brief, a paradigm shift is urgently required in water politics the world over to prevent further damage to sensitive ecosystems, and to the aquatic environment.
Bubble-less MABR system can reduce energy costs for wastewater aeration CREATING A BUBBLE-LESS AERATION OPTION The secondary or biological stage of traditional activated sludge wastewater treatment plants is where most of the energy is consumed. It far outweighs the operational costs of pumps, mixers, chemical addition, lighting, heating, etc. Oxygen needed by bacteria used in this stage is usually delivered in the form of atmospheric air, through mechanical equipment, and usually against a hydrostatic pressure created by four to six metres of water depth. Rotating blade mixers, jets and/or large blowers are needed to push air through this pressure (head), to ensure all bacteria receive sufficient oxygen.
