ACT suburb required customised solution for potable water tank

Eductors can be a game changer when it comes to mixing liquids in suspension because they can eliminate the need for mechanical devices. But, finding the right eductor that’s suitable for large tanks can be challenging so that’s where a bespoke designed and manufactured eductor solution may be required.

The developer of a new residential area in the ACT required custom designed and manufactured eductors to suit the requirements of its 900,000 L potable water reservoir. As part of the design process, the eductors were required to accommodate precise specifications such as:

• water velocity;
• a flange to suit the pipework; and
• capacity to mix liquids in such a large tank.
   

Tecpro Australia provided the solution — giant cast 316 stainless steel eductors.

The custom-manufactured eductors are mounted to the bottom of the potable water tank. Liquid is cycle pumped into the tank through the inlet of each eductor. ‘Veins’ located part way down the eductor draw the surrounding liquid, mixing it and distributing it to the tank through the outlet of the eductor to ensure constant circulation.

As there are no moving parts, the eductors are maintenance-free, while the pumps used to fill the reservoir are located outside the tank. Feedback from the client was positive with “everything performing well, looking good and final commissioning underway”.

Tecpro Australia solutions are derived from both its range of off-the-shelf products as well as customised designs.
