Sewage Treatment Project for Swedish Holiday Homes
Project Overview
This project focuses on the sewage treatment of holiday homes in extremely cold regions of Sweden. The treated water volumes are 3.0 tons per day (t/d) and 7.0 t/d. The selected equipment models include BioFilter - 3000 and BioFilter - 7000 series.
Equipment Selection Basis
1. Extreme Environmental Conditions
Sweden's extremely cold regions have winter minimum temperatures reaching - 30°C. The equipment needs to withstand such low - temperature environments. The BioFilter non - powered and maintenance - free purification tank, with its HDPE tank material (wall thickness 14mm), has excellent compression and freezing resistance, suitable for the local climate.
2. Fluctuating Water Quality and Quantity
The domestic sewage quality and quantity of holiday homes fluctuate greatly. Moreover, there are no professional technicians on - site for permanent maintenance. The BioFilter purification tank uses nano - porous bio - enzyme filler, does not require electricity connection and maintenance, and can accept a maximum of 6 months of no - raw - water shutdown, meeting the project's operation requirements.
Equipment Performance in Use
After installing purification tanks of series models such as BioFilter - 3000 and BioFilter - 5000, the system has always operated stably. During the peak holiday season, it ensures the continuous and stable up - to - standard treatment of domestic sewage, effectively solving the sewage treatment problem of holiday homes in this area.
