The greenlife technology.
The ECO-BIS production line is an additional installation for standard WWTPs. It is added early on in the waste treatment process. Directly after the pre-treatment of the incoming waste water, turbidity and solids are removed with the ECO-BIS "Separator" technology. The advantages are that the separator process replaces the primary sedimentation process and that the chemical oxygen demand (COD) can be reduced by up to 70%. This also means that the quantity of sludge in the WWTP is significantly reduced.
Then the wet sludge is dewatered using the ECO-BIS "Vacuum Filter" technology. The new system consumes significantly less energy than any other known technology - less than 1 kWh/m³ wet sludge. Then the dewatered and dried sludges are carbonised into a high-quality carbon-phosphorus-fertiliser using the ECO-BIS "Pyrolysis" technology.
Reducing COD by up to 70 per cent!
The separator is a system for the mechanical separation of solids and liquids. The pre-treatment of waste water is carried out very efficient. Much of the turbidity and solids are removed via an ingenious combination of precisely calculated fluid dynamics, turbulence and gravitational forces. The chemical oxygen demand (COD) can be reduced by up to 70 per cent.
Less energy consumption in the aeration!
On average, two-thirds of the total costs of a waste water treatment plant incurred in the aeration. Due to the reduction of COD by the separator, less oxygen needs to be blown into the water to aerate the bacteria in the biological treatment. This reduces the energy consumption and operating costs of the plant.
Pimp your wastewater treatment plant!
For overloaded waste water treatment plants the separator and its effective pre-treatment saves an expensive expansion and comprehensive structural measures. If a waste water plant is built from new, it can be built smaller.
- efficient solid-liquid separation
- up to 70 % less COD
- less energy demand in aeration
- less operating costs
Dewatering: vacuum filter.
Economic and ecological dewatering of sewage sludges!
The vacuum filter system consumes significantly less energy than any other known dewatering system. Efficient dewatering is achieved through the use of ultra-fine filters and the vacuum effect. The vacuum filter is virtually maintenance free and requires only few chemical precipitants.
- less than 1 kWh/m³ energy consumption
- less operating costs
- high dry matter content
- easy maintenance
Sludge recycling: pyrolysis.
Turning waste water into a marketable product!
In conventional waste treatment plant nutrients such as carbon and nitrogen are not used as soil fertilisers because they are converted into CO and N₂. If the sludge is burned afterwards, the phosphorus goes by the wayside too. In the future, however, resources are dwindling. An innovative pyrolysis process is saving these nutrients by converting energy-rich sewage sludge into a valuable and marketable carbon-phosphorus fertiliser.
Less costs for disposal!
Each pyrolysis plant is converting 4.000 tons of dewatered sewage sludge (25% DM) in 500 tons of marketable fertiliser per year. The costs for sewage sludge disposal can be minimized.
