Industriewater Eerbeek (IWE) in the Netherlands, is responsible for the purification of the effluent from three different paper mills (approx. 4 million m3 of waste water per year). In summer 2018 IWE experienced a world first with a new decalcification process for reducing the calcium content of the effluent water. Now effluent can be reused as process water in the papier mills again. For both the pilot and the final full-scale decalcification plant, Landustrie supplied the LANDY surface aerators. The official opening of the new installation took place by State Secretary Mrs Van Veldhoven (Infrastructure and Water Management). In addition to these surface aerators, Landustrie earlier supplied a new LANDY screw pump for the influent pumping station and refurbished the clarifiers of the existing primary settling tanks.


STP Stockholm

The order for renovating three Archimedes screw pumps is not remarkable, but the location of Danviken Pump Station however is unique: in a cave in the middle of the city of Stockholm, near the Royal Palace and City Hall.

Landustrie installed three LANDY Archimedes screw pumps with a diameter of 2.60 meter.
Screw length 9.9 m - capacity 9720 m3/h - power 160 kW.
The screw pumps are supplied with eco-friendy lower bearings.

The sewage treatment plant in Stockholm is close to the ferries. The black water (human faeces) from the ferry, is pumped in to the STP via the screw pumps. As this water is very aggressive, the screw troughs are finished with duplex stainless steel and the screw coating is even more stringent.


Slowhill Copse WWTW

Slowhill Copse Marchwood WTW (Southampton, Hampshire) was originally constructed in the 1960's. The latest upgrade includes an improvement of the existing treatment process to meet the newest requirements. Landustrie supplied sixteen (4 per aeration lane) low speed surface aerators, type Landy-7 complete with drive units, bottom baffles and foundation plates.

Sewage Treatment Plant "Illidge Road" located at Sint Maarten, Netherlands Antilles, is being renewed.
The exisiting plant is expanded in order to accommodate the growing number of households. The old plant was built in 1992 with a capacity for 3,500 resident equivalents.
After the expansion, the plant will have a capacity of 30,000 resident equivalents, meaning that it will be able to serve 30,000 households.

Landustrie supplied the complete mechanical works, including o.a. inlet works with screen cleaning equipment, several mixers and pumps, surface aerators, flow boosters, Archimedes screw pumps, piping, sludge clarifier and thickener, etc.
