Smart systems for wastewater treatment

One oxygen atom linked to a couple of hydrogen atoms gives us the Earth’s most valuable resource. It can be said with unwavering certainty water breathes life into our planet and is required for maintaining its life balance.

Although the little rock we call home has a lot of green and blue, much of this blue is virtually unusable. 70 per cent of the Earth’s surface is covered by water, but only 2.5 per cent of it is fresh. A major portion is saline and ocean-based and thus, unfit for human consumption. This scenario by itself is a challenge, with the population on the rise at an alarming rate. Putting things into perspective, a UN study shows that between 1900 and 2000, the increase in world population was three times greater than during the entire previous human history -an increase from 1.5 to 6.1 billion in just 100 years.

To make matters worse, a study done by UNESCO shows that globally 2 million tons of sewage is being released into these water bodies. The effects of which are devastating to human life, flora& fauna, which depend on these resources for their survival. Contamination of water causes disruptions of food chains and destruction of ecosystems. A deadly by-product of this water pollution is the spread of water-borne diseases such as cholera, typhoid etc.

These facts by themselves establish the dire need for effective water treatment solutions that can help us tackle the predicament we have put ourselves in. Water treatment solutions help in ensuring that water is made fit for consumption and at the same time, it is not wasted. Existing and obsolete water treatment plants need to be modified so that they are better equipped to handle challenges of the current scenario.

Urbanisation in India is developing at an unprecedented rate, in turn, driving the government bodies to look for ‘effective wastewater management solutions’. Smart wastewater management systems and real-time monitoring are two broad solutions for effective wastewater management. Their establishment and operation consists of enormous scope of deploying intelligent solutions such as smart pumping solutions, efficient treatment and reuse.
