Advantages:
1. Most effective & long lasting technology available presently. With regular treatment, the arsenic level will steadily remain >2 ppb. The currently operating SAR plants have maintained the water quality for the past three and half years.
2. It is also the easiest technology around. Every plumber & electrician in the village can do the operation & maintenance once they are given a simple training.
3. The SUSTAINABLE way of treating arsenic contaminated water. This process not only removes arsenic & iron from the water pumped out through the system, but also treats the contaminated aquifer.
4. Easy Operation & Maintenance: The whole system is very cheap to operate & maintain.
5. More there is iron in water, more effective the process is. The arsenic gets adsorbed in the soil particles coated with Fe(III) is not released.
6. Waste disposal is not a problem. During operational phase, nearly ZERO waste is generated since iron, arsenic & other impurities such as Mn, nitrates, nitrites, etc gets adsorbed in the soil particles within the aquifer itself.
7. Large supply of Arsenic free water can be obtained by running the treatment cycle for more than once per day.
