Abstract:
In the present scenario the safe and pure drinking water is the necessity of each individual and becoming a challenging task to provide pure and safe drinking water availability. Water is essential for agriculture, industry and human consumption Researchers spent vast amount of time and resources in developing various methods to develop for how best water can be utilized. Particularly in Punjab, report from Punjab News line Network, Monday, 14 June 2010 confirms the high level of Uranium and other dangerous heavy metals present in water samples mainly from southern Malwa region and is responsible for retarded children,. It is crippling children's brain.
Various techniques are available for making salt water into a safe drinking water Reverse osmosis technique is one of them. CSMCRI, Bhavanagar & CEERI-Central Electronics Engineering Research Institute (Constituent laboratories of CSIR ) have come together to develop a CSIR technology for addressing the above problems. The developed embedded system provide the better quality product with the use of advance monitoring and controlling algorithms. The Industrial PC based RO automation system is equipped with high performance data acquisition and control (DAS) card, suitable sensors and opto-isolated I/O controls for continuous monitoring and control. The control algorithms are developed using NI LabV1EW virtual instrument platform can be ea.,ily adopted for any high capacity RO plant. Appropriate sensors like temperature, pressure, PH, TDS and turbidity etc. are installed for continuous measurement and data logging will give better quality product and safe operation. The system provides features for set points, to display trend graphs and history graphs apart from controlling the required RO plant operations. Providing safe drinking water is the highest priority for all local and state agencies. Safety of the plant is at risk if it is not monitored. The developed automated controlling system plant will give higher and consistent out put.
