The importance of recycling wastewater
As an essential commodity all over the world, we need to do as much as possible to ensure that water is safely used and redistributed. Whilst we tend to think of water shortages and non-clean supply as a 3rd world problem, there are however still over 7000 deaths a year in the US attributed to unsanitary water supply, which can’t be acceptable today.
The global water and wastewater treatment market size was USD 265.30 billion in 2018 and is projected to reach USD 456.68 billion by 2026. To assist with this growth Water treatment plants are looking to go digital, though this is still in its infancy, it can be one of the most green industries to work within.
As the Wastewater industry grows and diversifies at a rapid rate, the regulations supporting it are immense. Water treatment plants do not just clean water, they also use their own bio-product to generate energy for the plant itself, provide processed remains as fertilisers for farming communities and recycle water back into the natural waterways.
The Circular economy
The industry is multifaceted and becoming what is now termed a circular economy and is an ideal example of recycling to make the best use of waste products whilst also protecting the environment. Water is utilised, collected, cleaned and returned to its source before utilising this all over again. This is the only real sustainable way of ensuring that water is available and continues to be so whenever we need it.
However the next conundrum comes in making sure that wastewater is fit for human consumption. Did you know that only 3% of the world’s water is actually fit for consumption? Although 71% of the earth’s surface is water, it is far too salty to sustain human life, crops or plants on land. The heavy levels of salt are also far too corrosive for many industrial uses. Of the remaining 3%, two thirds of this is contained in glaciers and the atmosphere. Leaving only 1% shared between a growing global population, which is said to top 9 billion, in the near future. This highlights the need and importance of handling water and its usage differently. The best way is to recycle the water we use, clean it, and send it back out into the community.
This is where Delta Mobrey and some of our products come into their own. We have a range of sensors to assist water treatment plants in understanding their sludge level in a sediment tank. These include our MCU200 and gap sensors which are presently used in a variety of plants across the UK.
Bearing this in mind Delta Mobrey was asked to assist with some of the measurement and reporting in the final settlement tanks of a water company based in the south of England. The customer needed to make sure that the sludge blanket layer would not rise to a level where it would overflow to the surrounding weir and then be discharged into the waterways. The recommendation to meet this customer’s challenge was to use a gap sensor and a control unit that was fitted onto a rotating bridge in each of the Final Settlement Tanks.
By identifying the problem and the location early, untreated water can be prevented from entering the clean water system. A lot of financial and administration time was saved, and the legal and social responsibility of the company is maintained.
The solution was a combination of The Delta Mobrey Undissolved Solids Sensor, the 433SD, designed specifically for sludge level detection in tanks, combined with the Delta Mobrey Control Unit, the MCU200 series. Together they provide a simple and cost-effective electronics system with LED indicators and outputs for alarm status.
Alternatively we have our newly launched Ultrasonic range, these products have specific benefits in that they have no moving parts, corrosive resistant and maintenance free solution. These can be used for pump control, Tank mounting and wet wells.
