50 m³/h continuous supply of ultrapure water for chemical production

Induss IV: This project is a fully remote controlled water treatment plant that delivers 50 m³/h of ultrapure water, mainly for ingredient water in the production of chemicals but also partly as boiler feed water. The water is treated with RO followed by an EDI polishing and stored in a 2000 m³ buffer tank to compensate for variation in usage during the day.

The project is an outsourcing project for a chemical production company, who requested an extremely reliable flow of water at all times. The plant operates with three 25 m³/h production lines, of which one line is redundant for the highest delivery safety possible.

The plant includes more than 500 components that can be monitored and controlled at a remotely located central control room.

Water savings is also a main concern. Therefore the plant is equipped with RO-PLUS water saving technology.

Water treatment for Combined Cycle Gas Turbine

Grundfos has supplied water treatment plant for one of Poland's largest Combined Cycle Gas Turbines with a generation capacity of 400 MVe and 240 MWt, located in the town of Stalowa Wola.

This project is one of the first state-of-the art large CCGT gas fired power projects in Poland and part of Poland's drive to reduce reliance on use of coal for power generation.

The water treatment plant is designed and built to supply make-up water for high-pressure boilers as well as feed water for the district heating network.

The water source is a river. First step of treatment is coagulation and flocculation followed by sand filtration. EDR unit (electrodialysis reversal) as partial desalination plant is used afterwards.

Hereafter the water undergoes membrane filtration on double pass RO unit. Pretreatment to DPRO is antiscalant dosing and NaOH is dosed between the RO stages to bind free CO₂. Finally, the water is polished on EDI in order to reach ultra-pure water.

Additionally fully automatic CIP system is available to make easy cleaning of RO membranes when needed. The plant can operate with flexible output due to VFD controlled RO pumps.

Chemical-free make-up water solution for power plant

Energie Steiermark Power Plant in Graz has replaced their existing water treatment plant for producing make-up water. One of their main concerns was to avoid the use of chemicals. By using a double pass RO, membrane degasser and EDI from Grundfos, ultrapure water of a very high quality is produced.

Complete production plant for purified water

At the firm of Fertin Pharma, Grundfos has supplied, installed and commissioned a water treatment plant for purified water production used for cleaning purposes and for manufacturing of medicated chewing gum. After this expansion of the production capacity, the new plant can deliver 3,000 l/h of purified water. The facilities meet all current GMP* requirements from the US Food and Drug Administration (FDA) and the EU, all regulatory requirements for external environment and work environment, the EU Machinery Directive as well as current versions of the United States Pharmacopoeia (USP) and the European Pharmacopoeia (Ph. Eur).

* = Good Manufacturing Practice

The water treatment plant is designed for nonstop operation (365 days). Chemicals for sanitizing can be employed.

In the outlet of the RO system, the stainless steel in contact with media is AISI 316L. Surface roughness is better than Ra < 0.8 µm, welds < 1.6 µm. All welds are documented in a welding log.

The compact pharma unit (CU:PHARMA) is equipped with water-saving technology. The RO system is of the type RO-PLUS with a water recovery of approx. 90 % – without compromising on either operational reliability or water quality.
