Making Your Wastewater Treatment Plant More Efficient

 

Making Your Wastewater Treatment

Plant More Efficient

Wastewater Treatment plants are not usually the source of innovation - with many continuing to operate much as they did a few decades ago. However, you may have heard of some recent successes due to the commercial application of an innovative approach to treatment - using Membrane Aerated Biofilm Reactor (MABR) technologies.

This solution is gaining a lot of attention around the world due to the quantified benefits that combine to improve overall operational efficiency.

These benefits include significant improvements in energy efficiency, and reductions in tank footprint,  in sludge production and in operator support time.

Simply installing a number of MABR modules in an existing tank enhances treatment performance, and provides additional process capacity overnight.

Key Benefits Include:

  • 75% Energy Saving
  • 50-80% Tank Savings
  • 50% More Capacity

So how do you explore whether you should be considering OxyMem for driving efficiencies at your plant?

The following 3 step process will help you quickly evaluate whether this area warrants further exploration.


 Step 1 Understand What an OxyMem MABR is and What it Does?


 

Knowing how the MABR works helps you understand what it is, what it does and how it may fit into your wastewater treatment process?

Is it a highly efficient aeration system?  Would you like to increase the load treatment capacity or improve the effluent quality of your current aeration basin, your sequencing batch reactor (SBR) tank or even your MBBR without upgrading your blowers or without even entering the wastewater tank?

And when it comes to installation all you need is a crane and a few days to get it up and running.

Is it an advanced MBBR or advanced IFAS? Any process currently making use of an attached growth (fixed biofilm) media could be supercharged with OxyMem’s aerated media. Instead of inert, oxygen deprived plastic media being mixed in a bed of aerated wastewater, attempting to find oxygen for treatment, inefficiently, the OxyMem MABR media delivers oxygen directly to where it is required - the media surface. Oxygen is delivered directly to the biofilm itself. This supercharge is equivalent to an athlete performing in an oxygen rich environment as opposed to an oxygen deprived environment. Performance is enhanced, naturally.

Is it a means of reducing your sludge production?  One characteristic of the OxyMem system, an attached growth biofilm system, is its long sludge age.  Longer sludge age systems produce less sludge than conventional activated sludge plants, thus requiring less pumping, storage volume, dewatering, transportation and disposal. Our environment benefits from less tankers being on the road.

 

Step 2 Understand The Key Benefits

Input values into OxyMem’s easy to use online Design Tool to help you assess the potential tank volume you may require, the efficiency of running an MABR and the volume of sludge you may expect to produce. The results of this basic tool will enable you to compare the ongoing OPEX costs of MABR against any alternative treatment you are considering. Be sure to consider all the benefits offered, even the hidden ones such as savings on land procurement, sludge storage vessels and disposal costs, and the fact that blowers and a blower building may not be required at all on your site.

 

Step 3 Sign Up for a Trial

OxyMem offer a number of entry level trial options which will demonstrate the power of the MABR application on your existing municipal or industrial process wastewater. Having run a pilot test and gained confidence in the MABR technology first hand, clients are then able to scale up to larger plants with ease, and with the knowledge that their advanced technology system will be brought online and meet effluent consents with minimal process and minimal financial risk.


 

Summary

MABR can be dropped into legacy tanks, where available, to deliver additional treatment capacity (IFAS style) without interfering with the current treatment process. Up to 50% additional capacity may be obtained within a matter of days, offering all of the MABR benefits noted above. Why not see the benefits yourself with our entry level solutions?

Nitrous Oxide, Not So Funny After All

Nitrous Oxide, Not So Funny After All   Nitrous oxide emissions from wastewater treatment plants are 265 times more harmful to our environment than carbon dioxide. Nitrous oxide (N2O), a greenhouse gas which is emitted as an undesired bioproduct during the biological treatment of wastewater,  it is estimated to be responsible for six per cent of global greenhouse gas emissions, and it has a warming potential 265 times that of carbon dioxide (CO2). It is also one of the main contributors to depleting the ozone layer. The gas is created during the nitrification and denitrification phase due to nitrogen present in urea, ammonia, and proteins found in municipal wastewater. Despite these concerns, there is some reason for optimism because nitrous oxide has a much shorter lifespan of only 114 years compared to carbon dioxide, which can survive hundreds of years in the atmosphere. Therefore, making changes to reduce N2O emission can have a profound effect on the environment in a much shorter time frame. A report from 2019 showed that 6% of nitrous oxide emissions in the United States come from wastewater treatment. Given this prevalence, reducing, and mitigating process emissions from N2O will be paramount for the water industry over the coming decade. Currently the water industry is working towards monitoring nitrous oxide on treatment plants and considering how best to reduce emissions through optimization or upgrading of treatment processes. Could OxyMem be the answer? Investing in technologies which can limit emission and make plant activities more sustainable will be key. To date there has been significant interest in carbon emissions within the sector, but momentum is growing as interest shifts towards targeting harmful nitrous oxide and lesser-known greenhouse gases.  Denmark  In 2018 the Danish EPA launched a funding scheme for Danish utility companies dedicated to measurements of and mitigation actions towards nitrous oxide emissions. In the period from 2018 to 2020, nine Danish utilities have measured and registered nitrous oxide emissions from nine different wastewater treatment plants (WWTPs) under the EPA funding scheme OxyMem have supported Vandcenter Syd (VCS) Denmark, who partnered with Aarhus Vand Denmark, to demonstrate the benefits of MABR technology at the Ejby Mølle WWRF. Work started in the summer of 2018. The full-scale demonstration of MABR at Ejby Mølle provided some great insights into the technology, but one key aspect recorded was the significant difference in N2O emissions from MABR when compared against conventional activated sludge treatment. In this project VCS measured nitrous oxide emissions from the conventional activated sludge surface-aerated reactors and the MABR demonstration reactors. Liquid phase sensors were positioned in both the existing activated sludge tanks and the demonstration MABR tanks, and a gas analyser was used to measure nitrous oxide concentrations in the exhaust gas of the MABR units. Results showed that nitrous oxide emissions were on average one order of magnitude lower than those from the conventional activated sludge plant, even under much higher loading conditions. The initial results from the project are very promising and reflect the immense potential for MABR to achieve very intensive total nitrogen removal with low nitrous oxide emissions. United Kingdom -2030 Net Zero Goals Given the potential for the sector, further studies on N2O and the added benefits of MABR are to be formally carried out under a recent initiative by Anglian Water. OxyMem technology was chosen to demonstrate how MABR might help the UK achieve 2030 emissions goals. Plant design is already underway. The project will be funded through an Innovation Fund made available by Ofwat Anglian Water’s Triple Carbon Reduction solution, delivered in partnership with OxyMem, Element Energy Ltd, Jacobs, Cranfield University, University of East Anglia, Brunel University, Severn Trent Water, Scottish Water, Northern Ireland Water and United Utilities, has been awarded more than £3.5 million. It will use novel technologies to target a step change reduction in greenhouse gas emissions and electricity use in used water treatment and provide a new renewable energy source through green hydrogen production – 'triple carbon' synergy and contribution towards achieving net zero carbon emissions by 2030. Adam Brookes, Manager of Innovation Discovery, Anglian Water, said: “Funding for this project will greatly support the delivery of our own net zero routemap and the water sector's drive to Net Zero by 2030, filling a significant missing piece in the challenge. By collaborating with academia, businesses and other water companies, our project creates an elegant solution to eliminate part of the greenhouse gas emissions associated with wastewater treatment and position the sector within the developing hydrogen landscape, in line with the newly launched UK Government Hydrogen strategy.” Amanda Lake, Water Process Lead, Jacobs Europe, said: “We’re excited to couple an innovative pure MABR treatment solution with green hydrogen production. We know the outcomes could be significant for the water sector - lower nitrous oxide process emissions, a role in the green hydrogen economy, valuable resource recovery and application of best practice life cycle assessment methods. What a valuable chance to work together to open the door to the lower carbon, circular economy water sector we urgently require. OxyMem MABR technology could assist the sector in achieving their global environmental goals over the coming years, by enhancing current Wastewater Treatment Plants capacity and at same time help clients move towards achieving their future net zero carbon emissions.  OxyMem MABR enables clients to add or improve ammonia reduction on existing large works using only a few kW's, and the technology can be simply dropped into existing treatment plants without the need to build additional structures or stopping live processes which are key benefits to enable the sector to achieve global environmental goals over the coming years.
