On the basic metrics alone, the score was 58.8 and the rank 4. The score is now 56.7 and rank 2 (▲ 2 places). The difference comes from buying motives: they measure what the buyer asks before deciding.
Clewerin pyörivään bioreaktoriin perustuvat pienpuhdistamot erottuvat julkisella hinnalla (800S 7 478 euroa) ja selkeällä mitoituksella talouden kokoon. CE-merkintä ja pitkät huoltovälit on mainittu. Puutteina ovat kapea valikoima, takuutietojen puuttuminen ja se, että operoiva yhtiö selviää vasta tilausehdoista.
