- What is a PURROT® ( Worldwide protected: PCT/DK2013/050077)
A self-cleaning vibrating Rotor-filter integrated with a high pressure screw press. PURROT® can – ”without using chemicals”– conduct a mechanical separation which, separates organic matter and nutrients from "liquid":
The module is used primarily for separating liquid manure (manure separation), as well as sewage from the food industry and public wastewater treatment.
- Why a PURROT® (higher livestock production or less demand for area)
Whether it is Pig manure, Cattle manure or Digested media from biogas, then PURROT® primo 2015 proven, that (ref. the Danish provisions), the module can "reduce your area requirements by approximately 35%"and the transport by 75% - 95% if the concentrate is removed from the farm. Price: <2 kW-hours electricity per m3.
PURROT® can - with the very high level of separation without the use of chemicals - as the only separator, produce a Fibre-fraction with > 40% Dry Matter. If the fibre is mixed with the concentrate from the module´ integrated Hydro-cyklon (PURPHO®), the module can remove more than 2/3 of the raw medium's Organic / Volatile Solid, VS = (Calorific Value).
Bio-Waste -> Bio-Fuel
- Calculate your benefits of investing in a PURROT® for Manure Separation

Example: Raw "thin" sow manure with 3.1% Dry Matter. The Fibre-% represents after the separation only 4%, but contains 59% of the manure´ "calorific value" (= VS). If PURPHO® is used, the weight of the fiber along with the sediment fraction is 22% of the applied liquid manure, while 58% of P and 67% of VS is recovered in the mixture, along with 28% of TN. That is to say:
Distribution costs are reduced by 78% compared to, that more than 2/3 of the energy content is deposited / delivered!
The solids content of the fibre has throughout the EU-ETV-Verification - where PURROT® has been programmed to a high solids content (can be varied referred to Customer requirements) - been > 40% TS, (of which VS is always above 90%). Therefore, the fibre fraction in addition to Biogas is also very suitable for ex. Thermic Gasification or rapid composting and subsequent use as Bedding (Recycling).
