explanation:

A negative number suggests that there are no savings through the use of CF nature compared to other systems

The numbers include VAT. The numbers are average prices in Germany and may vary depending on region and country

1.1.) Pre-chamber + biological stage + post treatment depending on the system for 4 PE; for retrofitting costs for kit parts, costs for planning and application documents (up to € 500) and expert assessment (€ 400) must be added

1.2.) Transport is included in the price for most manufacturers, for distances > 100km, however, it generally must be added

1.3.) Costs are only indicative and may vary considerably depending on the region; retrofitting costs may arise when making the present chamber leak-proof

1.4.) Costs for crane depending on the system, when retrofitting costs for installing the kit + leak test

1.5.) The approval is done by the responsible authority depending on the country and state and is independent of the type of plant

1.6.) Commissioning is usually included in the price, ClearFox is Plug and Play

2.1.) Energy costs for magnetic-valves, blowers, pumps, control unit, malfunctions and telemetric depending on the system € 40-150
Calculation: Consumption in kWh/a x energy costs in €/kWh, assumption: € 0.29/kWh

2.2.) Maintenance costs include costs for wear parts (e.g. pump € 150/5y, blower € 375/10y, gasket kit € 40/2y, magnetic-valve € 50/7y, control unit € 675/12y) and expenses for replacement and repair at bio filters: Cleaning of the filter material € 150/2y, replacement+disposal € 500/5y (partly included in a service agreement). The costs for spare parts are based on prices to date and may vary considerably depending on the market and the manufacturer

2.3.) Primary sludge + secondary sludge depending on production, € 40.00/m3 + call-out charge € 20.00 average production: For SBR plants / aeration plants / fixed-bed plants: 3m3/y; biofilm plant with filtration / constructed wetlands for wastewater treatment / Clearfox nature: 1.5m3 per year (no secondary sludge)

2.4.) Service intervals depend on the building-authority approval, generally 2x/y for techn. plants; 1x/y for natural treatment plants. Assumption: € 90.00/service plus spare parts plus fault-clearing service blackout, defects, repairs, defect information

3.) Annual costs after 10 years with an increase in prices of 2%/y and increase in energy costs of 3.5%/y. The increase in prices are assumptions and may vary considerably depending on the market

4.) Sources for assumptions: Auth and Seyler, Bayer. Landesamt für Umwelt; Straub, Hochschule Lausitz, Cottbus; Herstellerangaben; BDEW (2015)
