Vacation House Project Case in Sweden (Overseas)

Project Type

Vacation‑House Domestic Sewage Treatment Project in Sweden

Treated Water Capacity

3.0t/d, 7.0t/d

Equipment Selection

BioFilter‑3000, BioFilter‑7000 and other series models

Operating Working Condition
In frigid regions of Sweden, winter minimum temperature can reach ‑30℃ with large fluctuation of water quality and volume for vacation houses. No on‑site professional technicians are available for maintenance, so selected equipment shall support long‑term shutdown without raw‑water supply.
BioFilter non‑powered maintenance‑free purification tank adopts nano‑porous bio‑enzyme filler. It requires no power supply or maintenance and can run continuously for 6 months without shutdown or water refilling. The tank is made of HDPE with wall thickness of 14 mm, featuring compression and frost resistance.
After installing purification tanks such as BioFilter‑3000 and BioFilter‑5000, the system runs stably and ensures consistent domestic sewage treatment even on holidays.
