General procedure of designing the technologies to obtain the end-products from pig manure: LTS (M)—long-term storing (maturing); SF—separation into fractions; S + BP—sedimentation in tanks with stop-logs and treatment in biological ponds; A + F—aeration and flocculation; A + C—aeration and coagulation; A + S—aeration and sedimentation in batch-type settling tanks; DF—fermentation in drum fermenters; CA—fermentation in chamber fermenters; PC—passive composting; AC—active composting; MemF—membrane filtration; MethF—methane fermentation; RO—reverse osmosis; TD—thermal drying; VD—vacuum drying; Gr—granulation; LOF—liquid organic fertilizer; L-PW—liquid (water) suitable for use in the processes; L-FI—liquid (water) suitable for additional fertilizing of fodder crops; Eff—methane tank effluent; L-D—cleaned liquid (water) dischargeable into the open water bodies; SOF—solid organic fertiliser.
