Water treatment plant built by Darcarion
Case studies

Plants we designed, built and handed over

Selected reference projects in semiconductor and specialty glass manufacturing — ultrapure water, DI distribution, effluent treatment, and the civil works that carry them.

The plant that serves an entire industrial park

Some plants we build. Others we are brought in to run. Darcarion operates the common effluent plant serving an electroplating park in Selangor — a facility we did not design, handling waste streams that leave no room for error.

Contract operation of a common wastewater treatment plant

Commissioned in 1998 and the first facility of its kind in Malaysia, the plant treats toxic effluent from an entire electroplating park. Rinse water arrives by gravity pipeline, concentrated solution waste by forklift in mobile containers, and chrome, cyanide, acid and alkali streams stay segregated from the shop floor all the way to treatment. We run it day to day.

  • Day-to-day operation of a common effluent plant
  • Segregated chrome, cyanide, acid and alkali conveyance
  • Continuous flow treatment for rinse wastewater
  • Batch treatment for electroplating solution waste
  • Neutralisation, precipitation and clarification
  • Sludge thickening and filter press dewatering
  • Final discharge to DOE Standard B

Reference projects

Designed, built and commissioned by us

Ultrapure water at semiconductor grade, high-purity distribution, effluent treatment to discharge standard, and the structural infrastructure underneath it.

Ultrapure water pretreatment upgrade

An existing ultrapure water train needed more capacity to support additional production lines. We upgraded the pretreatment end to end and extended the distribution loop into the new areas of the fab.

  • Multimedia and activated carbon filtration
  • Strong acid and strong base ion exchange
  • Reverse osmosis for UPW pretreatment capacity
  • UPW loop piping to new production lines
  • Control panel design, build and system tie-in
  • Testing and commissioning

RODI, hot DI and wastewater packages

Three packages delivered together: ultrapure supply at two resistivity grades, a hot DI circuit, and the drain and collection systems that carry production effluent away.

  • 10 MΩ and 2 MΩ DI water distribution piping
  • Hot DI water piping system
  • Production drain and collection systems
  • Double containment transfer piping
  • Wastewater transfer pump systems
  • Testing and commissioning

Design and build RODI plant

A complete RODI plant for a new production line — from raw water intake through to the supply and return piping at the point of use, with SCADA control across the whole train.

  • New RODI plant, design and build
  • Production supply and return piping
  • PLC SCADA automation for plant operation
  • Testing and commissioning
