Case Study-1:

Water Utility

Bangalore Water Supply and Sewerage Board

Challenges

BWSSB runs one of the most energy intensive pumping operations in India, bringing water to the city.

It was noted that SCADA systems were becoming obsolete in 5 to 7 years and supporting this had been a challenge.

Optimizing performance was a major challenge due to the lack of visibility of performance monitoring at equipment level.

Solution

Dynamic performance modeling deriving hydraulic parameters and performance from energy

Dynamic performance of modeling of pumps and systems.

Remotely managed services.

Outcome

The project identifies 12% energy saving from low cost measures, out of which 6% saving is achieved through optimum machine sequencing using the color coded performance dashboard for the operator. (Refer Performance Overview Dashboard above.).

Case Study-2:

Waste Water Utility

Municipal Corporation of Greater Mumbai - Sewerage Operations

Challenges

MCGM undertakes one of the most extensive network of sewerage operations in India handling 3000 MLD of water for Mumbai City through 52 pumping stations and 7 large waste water treatment facilities spread across the city.

The drastic variation in the sewage flow during the day and through the wet and dry seasons made the performance optimization a daunting task.

Solution

MCGM has awarded the single largest energy audit assignment in the country with performance modeling and simulation to a consortium led by Datamatrix.

Datamatrix used the modeling of the pumping station to understand the real time performance scenarios of the plant along with an extensive energy audit.

Outcome

The project identified 16% energy saving, mainly through optimum level management and machine sequencing at various pumping stations, besides asset management opportunities with 13% saving potential.

A detailed implementation program was chalked out by Datamatrix for continuous performance optimization for MCGM which helped to achieve and sustain savings as depicted in the following figure.

Case Study-3:

Pulp and Paper Industry

A pulp and paper factory in India

Challenges

The Plant faces two major challenges
a) In maintaining load within the maximum contract demand and
b) Optimizing the performance of the major utilities indicated above

Solution

Datamatrix provided an energy management system capable of monitoring the connected load and the maximum demand.

Outcome

The plant has saved nearly one million INR per month as the avoided average maximum demand in excess of the contract demand

Datamatrix is working on plant virtualization of monitoring and optimizing the critical machines such as refiners, advising the customer how to reduce energy and operating cost through optimum replacement of refiner plates; maximizing return on investments. The major rotating equipment and fluid handling systems are being monitored and optimized through our Virtual Metering Platform.

Case Study-4:

Water Management

Water Management for Building Complex

Challenges

Water management for buildings is a priority for many cities in India. The lack of data and awareness, is a hindrance to optimize building water use. There is a significant opportunity to reduce pumping energy and maintenance associated costs and improve reliability.

Several cities in India are currently facing acute water shortages and erratic water supply during peak summer. Some buildings have bore wells. The ground water in such a scenario is mismanaged due to lack of information on the aquifer and water stock, and are often depleted during summer.

Solution

The Datamatrix Technology was deployed for monitoring the pump. The system creates alerts in abnormal conditions such as water not available/level below the desired levels. The system also accounts for the energy and water use and carries out continuous energy and water audit. The sewage treatment plant is also being brought under the Datamatrix System.

The bore wells are monitored using energy simulations identifying the suction level, draw down level and water withdrawal. Datamatrix also derives the aquifer properties and manages the water withdrawal and recharge for maximizing the yield through summer. (Refer to similar case study of Ground Water Management (Research with Columbia University)

Outcome

The water shortage in the building during summer is being resolved as follows...
a) Monitoring and optimizing energy and water use by major pumps using Datamatrix Virtual Metering.
b) Reducing high pressure discharge from the water taps on the ground floor.
c) Monitoring and recharging the aquifer (using energy simulations), improving the groundwater availability in summer.
d) The efforts have reduced 12% water use per year and increased the water availability by around 25%, ensuring water availability throughout the year. The opportunities for reducing the energy use of pumps by 22% has been identified.
