Automation of wastewater management processes using fieldbus is also likely to become more common in the coming days. As Goel mentions, “A distributed control system (DCS) communicating with actuators to operate valves and other instruments can automate the process to a large extent. For instance, the Changi wastewater treatment plant in Singapore is a perfect example of the automation process used in wastewater management.”

Interestingly, many Indian companies were involved in the supply and execution of this project. The latest innovations in the bus systems and PLC integrated complete automation tools with pre configured and tested engineering libraries, built-in full suite of diagnostics and maintenance tools and integrated document management capabilities are adding value to all phases of the automation system project from design process to engineering, control system development, installation, commissioning, start-up and acceptance testing, all the way through to operation, maintenance, repairs and ongoing upgrades.

How to Comply to Stringent Regulations

Lakshmikantha opines, “ASCO Numatics G3 Valve Manifold system is a compact solution which can be used for the central control of the pneumatic actuators. This will also help easy integration with DCS systems.”

The automation segment is a highly diversified mix of vendors, technologies, and integrators. With pollution control initiatives getting more stringent, the coming years will see an explosion of analyzer vendors and technologies flooding the market with highly competitive value propositions for customers.

“The onset of Internet of Things (IoT), in conjunction with cloud computing and Big Data Analytics, is rapidly changing the way O&M contractors and plant owners manage plant assets. The need for continuous improvement has compelled plant operators to use these systems to unlock the potential information hidden under the piles of data points that a plant generates,” mentions Vaswani.
