PURROT^®

1. 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.
   
   
2. 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^[1] 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
   
   
3. Calculate your benefits of investing in a PURROT^® for Manure Separation

   PURROT®	Part in Fibre			Part in Fibre + PURPHO®
   Part of Raw Medium	Sow manure	Cattle manure	After biogas	Sow manure	Cattle manure	After Biogas
   Weight- %	4 %	12 %	10 %	22 %	24 %	20 %
   Phosphor TP	33 %	23 %	46 %	58 %	34 %	58 %
   Total-N TN	10 %	19 %	22 %	28 %	32 %	31 %
   Org.-N. N-org.	17 %	29 %	33 %	35 %	44 %	51 %
   Total Solid TS	48 %	54 %	56 %	59 %	62 %	60 %
   Volatile VS	59 %	60 %	62 %	67 %	68 %	66 %

   The table shows the proven separation results from the verification.
   
   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).
