Dosage technology

ENSPAR offers robust and low-maintenance technology for the dosing of solid substrates, e.g. maize, GPS, grass silage, solid and poultry manure. The feed into the digester is carried out using proven screw technology below the liquid level.

Dosing units for solid substrates

A biogas plant can be fed evenly and reliably with a screw conveyer system in combination with a solid dosing unit. The substructure of the dosing unit is standardly manufactured of stainless steel. Optionally, the top element, the mixing screw and it´s knives can likewise be delivered in stainless steel. Low wear is thereby guaranteed.

The drive operates with robust geared motors with subsequent cardan shaft and planetary mitre gear. A shear pin clutch is integrated in the powertrain as safeguard. The consistency of the added material has a decisive influence on the duration of the mixing process. An optimal operation is guaranteed with chopped raw materials of 3-5 cm length. For longer materials, we recommend the use of cutters in the dosing units. 

 

 

Liquid dosing 

For the safe and reliable injection of solids into a flow-through, closed piping systems, ENSPAR's liquid NawaRo injection technology is a guarantor. We recommend this technique for plants with a high liquid share and fibrous materials. 

 This dosing technology is available for the injection of up to 5t / h or up to 9t / h. The Fastfeed 300 can handle up to 4 t / h at very low, wear-resistant speeds, while the Fastfeed 400 can deliver up to 9 t / h. The feeding power can be increased by increasing the rotational speed.

Sectors

Profitable recycling of residues

Tons of organic residues that release methane during decomposition are accumulated in agriculture, food production and wastewater treatment. This gas can contribute significantly to climate change if it is emitted unchecked into the atmosphere.

Wastewater technology

Prozessing of manure, digestate and industrial wastewater

The disposal of manure, digestate and industrial wastewater is expensive and laborious. In many regions there is a strong oversupply of liquid manure and digestate from biogas plants. Food-producing companies generate highly contaminated wastewater. What is needed, therefore, are sustainable solutions that facilitate the transport of residues and reduce nutrient surpluses. ENSPAR has developed a treatment solution for the processing of highly polluted waste water streams of liquid manure, digestate and industrial wastewater.

Concept processing plant

In the processing plant, solids are separated from the water in a multi-stage process. Depending on the requirements, the treatment is supplemented by classical sewage treatment plant technology with nitrification and denitrification or by the proven reverse osmosis process. What remains are solids in varying amounts of water and in reverse osmosis a liquid nutrient concentrate.

The reliable technology convinces users by a high technical plant availability. The system is modularly scalable and can be used economically from as little as 20,000 m³ per year.

Process sequence with reverse osmosis

  1. Flocculation & polymerization
    In a mixing unit, raw materials and additives are mixed. This allows a fast reaction time and the economical use of coagulation and / or flocculants. By adding the additives flake fine components and can be easily separated from the water. In addition, the addition of the additives leads to better separation of certain substances and minimizes odor emissions.
  2. pressure filtration In the next step, the pretreated materials are dewatered with a special belt filter press. They are pressed with increasing pressure on a wire belt via different rollers and rollers against a second, water-permeable belt. The result is a dehydrated solid with a TS content of 30%. This can be used as fertilizer, compost, animal bedding or biogas substrate or dried up with the waste heat from the biogas plant.
  3. Flotation & fine filter

    The remaining aqueous phase is aerated in a stainless steel flotation tank. Small particles and suspended matter settle on the tank bottom as sludge, which can be reticulated in the process. The remaining solids in the pool are separated by a filter.
  4. Reverse osmosis & ion exchanger
    For the final cleaning of the already well-clarified liquid phase, a three-stage reverse osmosis is carried out. The semipermeable membranes of the reverse osmosis unit can deposit 95 to 99% of the dissolved salts and nutrients. The nutrient concentrate obtained can be used as an easy-to-transport liquid fertilizer. The remaining water is cleaned after the reverse osmosis abschießend an ion exchanger and can then be used as process water for various purposes on the system or the water cycle zurückgeführt.einem a stainless steel flotation basin ventilated. Small particles and suspended matter settle on the pelvic floor as sludge, which can be reticulated in the process. The remaining solids in the pool are separated by a filter.

The processing plant convinces by a high quality of technology and conception.
