Industrial Energy & Water Optimisation Projects

SARK Engineers & Consultants supports industrial plants with engineering-led projects involving energy reduction, water conservation, utility optimisation, wastewater reduction and production-linked resource efficiency.

Assignments may involve individual systems such as pumps, boilers, chillers or cooling towers, or a broader plant-wide review connecting:

  • electricity;

  • fuel;

  • steam;

  • cooling;

  • compressed air;

  • pumping;

  • freshwater;

  • wastewater;

  • ETP/STP;

  • reuse;

  • production demand.

The objective is not simply to identify theoretical savings.

It is to identify technically practical improvements that can be implemented within the operating constraints of the plant.

Example Project: Pumping Power Optimisation

Problem

An industrial pumping system may operate far away from its efficient duty point because of:

  • oversized pumps;

  • throttling;

  • excessive head;

  • parallel pumps operating unnecessarily;

  • incorrect impeller selection;

  • poor piping hydraulics.

Improvement

Potential measures may include:

  • impeller trimming;

  • VFD control;

  • pump replacement;

  • system-head reduction;

  • revised parallel-pump logic.

​Engineering Review

The assessment may involve:

  • flow measurement;

  • suction/discharge pressure;

  • operating head;

  • motor loading;

  • pump curve comparison;

  • system curve;

  • throttling losses;

  • operating hours.
