We have thousands of RAITA BioKem sewage treatment systems in function,
mostly in Finland, Scandinavian, Baltic countries and in Russia.
We have tested our processes by european (EN 12566-3:2005) and f.ex by
russian, estonian, swedish standards. In all the countries the plants are
delivered, their effience is better than the required limits. The RAITA Multi
process normally cleans up their effluent to the standard which is required
for swimming waters but it’s efficiency may also be even higher.
Beside of waste waters of living (sanitation waters) we have references f.ex
of dairy farms, food industrys waste waters.
Here we have purification resuts of 13 RAITA XL
plants which have been under authority
supervision. As the result of over 3000 samples
taken and analyzed, 99 % show excellent
purification result.
