The Water Corporation for Western Australia is responsible for the supply of drinking water in Western Australia. One of its production plants, the Neerabup groundwater treatment plant, supplies part of the area around Perth with drinking water. A renovation and extension of the treatment plant, which should also include a softening stage, was considered necessary.
Royal HaskoningDHV provided input for the pellet softening reactors based on Crystalactor™ technology: pilot testing, technological design, preliminary design, technical design, site supervision, procurement of special components for the Crystalactor reactors, technical and technological start-up, instruction of operators and preparation of operation manual.
The pellet softening stage comprises of 6 reactors, each with a square cross section of 3.2 m x 3.2 m and height of 8 m. A special feature in the reactor design is the way the reactor bottoms are constructed.
Neerabup is the first Crystalactor softening plant in which the filter bottoms are made of concrete instead of steel.
