Piping in stainless steel and HDPE for expansion of demineralized water production (water-link)

Purpose

Due to the increasing demand for demiwater (demineralized water), the production capacity at water-link was expanded with two mobile RO units. Due to space constraints, flexible container solutions were chosen. This required adjustments to the existing infrastructure with a focus on piping.

Problem-solution

Our assignment? To design, install, and integrate new piping to connect the RO units to the existing system. This consisted of:

• Piping inside the plant: RVS316L for raw water and permeate.
• Piping outside the plant: HDPE for concentrate and wastewater.

Scope:

1. Feed water pump connection - Installation of a new DN300 pump (300m³/h) including foundation, valves, and compensators.
2. Piping to RO units - stainless steel316 DN300 with shut-off valves, metal pipe rack and insulated flexible connections.
3. Connection permeate tank - stainless steel DN300 piping and epoxy-coated foundation.
4. Transport to mixing bed collector - stainless steel316 DN150-DN300 piping.
5. Concentrate disposal - HDPE piping, insulation and new 10 m³ wastewater tank.
6. Wastewater disposal - Installation of a new wastewater pump and HDPE DN150 pressure piping to the metering station.
