Anaerobic System Design and Technology | US EPA

A batch digester is the simplest form of digestion, where manure is added to the reactor at the beginning of the process in a batch and the reactor remains closed for the duration of the process. Induced Blanket Reactors are digesters in which a blanket of sludge develops and retains anaerobic bacteria, providing a bacteria-rich environment

Kraft process - Wikipedia

The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibers, the main component of paper.The kraft process entails treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white liquor, that breaks the bonds that link lignin

fits well into the daily routine. Gas production is constant, and higher than in batch plants. Today, nearly all biogas plants are operating on a continuous mode. If straw and dung are to be digested together, a biogas plant can be operated on a semi-batch basis. The slowly digested straw-type material is fed in about twice a year as a batch load.

Overview of Paper Pulp Cooking Digester

The size of wood pulp produced under 300t/d is best used in large and medium batch cooking digester, because the investment cost of batch cooking pot is 13% to 20% lower than that of continuous cooking digester under 300t/d. The wood pulp production is above 300t/d, and the continuous cooking digester should be selected.

Biogas from Manure

Mar 05, 2012 · Digesters can be loaded with slurry continuously or by the batch. A batch-load digester is filled to capacity, sealed until it has produced all the biogas it can, emptied, and filled again. Gas production is uneven because bacterial digestion starts slowly, peaks, and then tapers off as the volatile solids are consumed.

Following this time period, the digester is manually emptied and reloaded. In a continuous flow digester, feedstocks are constantly fed into the digester and digested material is continuously removed.
