Lighting for wastewater treatment plant: ZUG LED in operation
ZUG LED – The robust luminare for demanding environments
Our luminaires provide the right light for the “Czajka” sewage treatment plant in Warsaw. Other luminaires have been unable to cope with the high demands of the harsh environmental conditions – namely, extremely high humidity and hydrogen sulphide in the atmosphere.
Lighting as a safety factor
The “Czajka” treatment plant is the largest state-of-the-art sewage works in Poland, located in the Białołęka district in Warsaw. “Czajka” is used to collect urban waste water and the waste water from surrounding municipalities and another water treatment plant.
Two underground basins of the plant have proved to be particularly difficult when it comes to lighting: zero daylight and high levels of humidity mean a high risk of accidents occurring. It is absolutely essential for the lighting to function properly.
Challenge in the depths
Extremely high air humidity and concentrations of hydrogen sulphide permeate the atmosphere of the two basins. This places high demands on the materials used: They must not only be waterproof, robust and resistant to hydrogen sulphide vapours, but their maintenance requirements also need to be as low as possible.
These are challenges that all previous luminaires failed to meet. Repeated attempts at repairs were only ever able to remedy the situation for short periods of time. The installed luminaires became brittle, water seeped in and they had to be repaired twice a month. The maintenance costs rose accordingly.
ZUG LED proves its reliablity
In their quest for reliable, well-functioning lighting, the power plant operators approached our Polish trade partner who found the perfect solution in our ZUG LED luminaires: Waterproof to 20 metres with their protection rating of IP 68, they are not only resistant to chemicals, but are also low maintenance. For some years now, the ZUG LED luminaires have been done their job and defying the hostile conditions – no repairs or unscheduled maintenance have been necessary.
