Overview

Aqua Engineering GmbH is based in Mondsee,in  Austria, is a subsidiary of BWT - Best Water Technology, Europe’s leading company in the field of water treatment with an annual turnover of app. 350 million € and a workforce of more than 2500 people.

Their areas of expertise include drinking water and industrial water supply, seawater desalination and wastewater treatment.

Aqua Engineering recently completed a 560,000-litre/day seawater desalination plant at Bay-Gan Island in Taiwan where Grundfos pumps play an important role in the treatment processes as well in moving the water within the system.

The Situation

The history of Best Water Technology dates back to 1823. For almost two centuries treatment and distribution of water has been a cornerstone of their business. Through “organic” growth and a series of strategic buy-outs the business has grown to become Europe’s’ leading in its field.

Aqua Engineering GmbH specialises – among many other things – in building and maintaining high-efficiency water supply plants. It is common practice for Aqua Engineering to buy pumps and dosing equipment from various suppliers from Europe and the USA. This makes it difficult to optimise the operation of all system elements while complicating staff training and after-sales service. Aqua Engineering, therefore, searched the market for a full-line supplier for all their pumping needs.

The Grundfos Solution

For the seawater desalination plant at Bay-Gan Island in Taiwan Grundfos supplied a full range of booster units, feed pumps and service pumps as well as a range of dosing pumps, each dedicated to dosing a specific chemical/additive.

The pumps supplied include two Grundfos BMET 17-12/8 high pressure boosting units, capable of delivering at maximum pressure of 700 m with a maximum capacity of 95 m3/h. In order to feed to booster units Grundfos CRN 32-2 pumps were installed. Additional CRN pump types were installed to handle permeate transportation, membrane flushing, cleaning operations and service water.

The highly advanced Grundfos Dosing pump range comprises two basic types, DMS and DME. The DMS models are mechanical dosing pumps fitted with a synchronous motor that varies the stroke frequency to meet demand. These pumps combine high throughput with reliable operation.

The Grundfos DME diaphragm pumps offer state-of-the-art digital dosing, which makes any setting and operation difficulties a thing of the past. The suction/discharge diaphragm is screwed into a crankshaft, which means that the diaphragm is fully controlled throughout every suction/discharge cycle. The operation range of the DME pumps is 2.5 ml/h to 150 l/h.

The Outcome

With the all-in-one solution provided by Grundfos, Aqua Engineering achieved not only efficient and trouble-free operation of all pump systems – and, thus, the entire seawater desalination plant at Bay-Gan Island in Taiwan. The logistics and training of staff members has also been greatly simplified.

In addition to the actual pumps Grundfos supplied all the necessary accessories in order to ensure optimum operation from day one. These included pulsation dampers, pressure relief valves, injection units, level switches incl. section pipes and mixers as well as tools, spare parts and service kits.

TESTIMONIALS

Mr. Braunwieser, Engineer and Project Manager,
Aqua Engineering GmbH.

"For certain projects Aqua Engineering prefers to cooperate with a one-stop-shopping supplier that is able to offer a high technical standard, compatible with our own, as well as efficient after-sales service, maintenance and staff training. Easy maintenance is a key factor in all our plants. Grundfos is capable of offering all of this in addition to short delivery
times compared, for instance, to competitors from the USA"
