ENBAFERM AD„High Load Hybrid Reactor“ • Patent pending
Influence of Substrate Characteristics • Maintaining cell vitality and groth of new bacterial sludge • Diet of micro-organisms must be supplied • Vital nutrients: Carbon, Nitrogen, Phosphorus, Minerals, Trace-Elements • Limitation of vital nutrients: stop of metabolic activity • Currently controversal discussion about addition of nutrients („wellness-drink“ for microbes) • Example: Washing-water of food industry nutrients + pH regulation necessary
Protein Containing Waste / Waste-Water • H2S in biogas • NH4+ in sludge and effluent • foaming as a result of gas mixing • metabolism-generated alkalinity
Fat Containing Waste / Wastewater • scum layers • bioavailability • toxicity • slow degradation
MAIN PROCESS- AND SUBSTRATE- RELATED FACTORS • temperature • mixing (process configuration) • retention time (loading rate) • substrate (type, composition) • C:N:P -relation • total solids • concentration • sulfur compounds • pH • organic acids
MSW OFMSW • variability • inerts • expensive pretreatment • depends on attitude of community
Complete Stirred Reactor • Mixer (Agitator) (e.g. CSTR) • Hydraulic Mixing • Tubular reactor with paddles
High Load Systems without particles and low COD UASB = Upflow Anaerobic Sludge Blanket Application: Washing-Waters, WW paper industry,
ENBAFERM New Technology UASB CSTR
High Performance Process TechnologyENBAFERM • Low Hydraulic Retention Time low demand for fermenter volume • Prevention of Foam and Floating Layershigh loading rates • Intense Contact between Substrate and Microorganismshigh degradation rates and rapid gas production
