    Improvement of Biogas Quality
    I am working a research on Hydrochar adsorbent for hydrogen sulphide in the circulation of Biogas at AnMBR. So, can you please give me some ideas on this issue which help me for my research to be improving (I know, you may not understand in detail what I am doing but you can give me general comments.)

    It has become apparent to others how much the effluent influences plant growth as fertilizer, and farmers are now eager to apply it. We are selling it at a low price ($.30 per 5 gallon jerry can) to encourage use.

    A Puxin 16 m3 digester was placed in the elbow of the building. Effluent that leaves the digester is pumped into the blue barrel, giving hydrostatic pressure for the flush toilets. So we are recycling digester effluent in order to flush the 10 toilets and 11 urinals. This seems to work quite well, but the particles in the effluent plug up the toilet resevoir entry valves.Next project is a filter system to clean up the lines.
