  • Umeå Wastewater Treatment Plant

    Type: 
    Product
    Objective:

    Within Umeå municipality there are a total of 19 wastewater treatment plants. The largest, Umeå Wastewater Treatment Plant, takes care of wastewater from households and various businesses in Umeå and surrounding villages. Every year, it receives about 13 million cubic meters of waste water, containing about 3000 tons of organic material and about 80 tonnes of phosphorus. The process of cleaning water demands a lot of energy, but the plant also produce biogas which gives 23 000 kWh per day. Clean water

  • Improvement of Agri-food processes

    Type: 
    Technology
    Sectors:
    Objective:

    The agri-food industry comprises an integrated complex production chain which ranges from the primary agriculture to the mature food and beverage sector. It is considered as one of the largest sectors  worldwide with significant contribution to the economic advancement of nations and major social impact.

  • Fertiliser, manure and straw management (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    Fertiliser and manure management in rice fields are important methane mitigation technologies. The fertiliser management mitigation option includes changes in: fertiliser types; fertiliser nutrient ratios; the rates and timing of applications; and use of nitrification inhibitors to reduce methane emissions by affecting methanogenesis in rice fields. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.

  • Straw ammoniation and silage

    Type: 
    Technology
    Sectors:
    Objective:

    Straw ammoniation is a process by which low-value forage such as corn stalks, rice straw, wheat straw, and straw of other crops is ammoniated. Adding liquid ammonia, urea, or ammonium bicarbonate as ammonia sources result in the straw lignin being completely degraded, while the nutrients are enhanced. It is made more easily digestible by rumen microorganisms, which increases the digestibility of forage.

  • Mid-season drainage (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    Mid-season drainage involves the removal of surface flood water from the rice crop for about seven days towards the end of tillering. The duration of the dry period must be long enough for rice plant to experience visible moisture stress. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.

  • Livestock management

    Type: 
    Technology
    Sectors:
    Objective:

    Livestock are important sources of methane. The United States Environmental Protection Agency calculated that livestock, especially ruminants such as cattle and sheep, account for approximately one-third of global anthropogenic emissions of methane (US-EPA, 2006). The methane is produced primarily through the process of enteric fermentation and released through the process of eructation (Crutzen, 1995). In addition, N2O emissions are generated by livestock through secretion of nitrogen through the urine and faeces.

  • Reverse osmosis membrane technology

    Type: 
    Product
    Objective:

    Membrane which permeates solvent (water) but does not permeate solute (salt). In desalination, pressure up to 10MPa is applied to seawater which enables water to pass through the revere osmosis membrane, while the salt is excluded.

    Currently, two types of material are used: bridged aromatic polyamides, and cellulose acetate. Membranes must withstand high pressure and also be resistant to fouling.

  • Sjölunda Wastewater Treatment Plant, Malmö

    Type: 
    Product
    Objective:

    Sjölunda Wastewater Treatment Plant, Malmö At the Sjölunda plant in Malmö wastewater from 550,000 inhabitants is treated. The plant was built in 1963. Recently expansion of biological treatment has reduced the use of precipitation chemicals to meet the Swedish requirements and the plant has at the same time reached emission requirements of organic compounds, phosphorous, and nitrogen. The sludge produced is used at the plant’s own production unit for biogas.

  • Jua Kali hydram

    Type: 
    Product
    Objective:

    Water fall pump based on hydrostatic pressure.

    A hydram (hydraulic ram pumps) is an automatic pumping device which utilises a small fall of water to lift a fraction of the supply flow to a much greater height.
