Manufacturer wholesale & retail anaerobic reactor UASB reactor IC reactor fermentation tank

UASBThe reactor consists of the following components: the inflow and distribution system, the reactor vessel, and the three-phase separator.

InUASBThe key equipment in the reactor is the three-phase separator, which is installed at the top of the reactor and divides it into the lower reaction zone and the upper sedimentation zone. To achieve effective separation of sludge flocs from the rising flow in the sedimentation tank,/Satisfactory settling effect of particles; the primary purpose of the three-phase separator is to separate the sludge bed as effectively as possible./Biogas produced within the layer, especially under high load conditions, is prevented from escaping through gaps between the collection chambers by the reflective plates beneath them. Additionally, baffles are beneficial in reducing the liquid turbulence caused by high gas volumes within the reaction chamber. The design of the reactor should ensure that sludge particles or flocs can slide back into the reaction chamber as long as the sludge layer has not expanded into the sedimentation tank.(It should be recognized that sometimes the expansion of sludge layers into the settler is not a bad thing. On the contrary, the expanded sludge layer within the settler will trap and aggregate the scattered sludge particles./Fibrous, and it also concerns the biodegradable solubilityCODIt serves as a certain degree of removal effect.)On one hand, there is a certain amount of free space available for sludge layer expansion, which is important to prevent heavy sludge from being lost under temporary organic or hydraulic load shocks. Hydrological and organic(Gas production rate)Load rates will both affect the expansion of sludge layer and sludge bed.UASBThe system principle is based on forming sedimentation-performance-excellent sludge flocs, and it combines a sludge sedimentation system within the reactor to achieve separation of the gas, liquid, and solid phases. To form and maintain sedimentation-performance-excellent sludge(It can be sludge in fibrous form or granular form.)IsUASBThe cornerstone of the system's smooth operation.

 IC Anaerobic Reactor

I. Overview：

    The IC anaerobic reactor is a multi-stage internal circulation reactor featuring numerous advantages such as a small footprint, high volumetric loading, uniform water distribution, strong shock resistance, superior stability, and simple operation. For instance, when dealing with high-concentration organic wastewater with a COD of 10,000-15,000 mg/l, the IC reactor offers the following benefits:

1. Rich container load capacity;

2. Small land area, saving base investment.

3. High impact load resistance.

4. Good stability of water output.

II. Working Principle:
The IC reactor is characterized by a large diameter-to-height ratio, typically reaching 4-8, with the reactor height around 20 meters. The entire reactor is composed of stacked anaerobic reaction chambers. Each anaerobic reaction chamber is equipped with a gas, solid, and liquid three-phase separator at the top. The primary three-phase separator primarily separates biogas and water, while the secondary three-phase separator mainly separates sludge and water. The incoming water and回流污泥 are mixed in one anaerobic reaction chamber. The reaction chamber possesses a significant organic removal capacity, allowing the wastewater entering the reactor to be further treated, removing remaining organic matter from the wastewater and improving the effluent water quality.
Three.Application Features:

◇ Compact structure, saving land area ◇ Utilize biogas internal energy to achieve internal circulation, no external power required
High impact load resistance
◇pH buffering capability
Good water output stability
◇ Reliability
Low infrastructure investment
FourCurrent Status and Future Prospects of IC Processing Technology Applications 
IC processing technology has been successfully applied in wastewater treatment for potato processing, chicory processing, beer, citric acid, and papermaking since its inception. In 1985, the Netherlands was the first to use an IC reactor for treating potato processing wastewater, with a volume load (calculated as COD) reaching 35 to 50 kg/(m³·d) and a detention time of 4 to 6 hours [9]; whereas the volume load of a UASB reactor for treating similar wastewater is only 10 to 15 kg/(m³·d), with a detention time of several to dozens of hours [3].
In beer wastewater treatment processes, the application of IC technology is prevalent, with several breweries in China having already adopted this technology. The operational results indicate that the IC process has a volume load (measured by COD) of 15 to 30 kg/(m³·d), with a detention time of 2 to 4.2 hours, and a COD removal efficiency ηCOD greater than 75％[9]; whereas the UASB reactor has a volume load of only 4 to 7 kg/(m³·d) with a detention time of nearly 10 hours[3].
For treating organic wastewater with high concentrations of concentration and salinity, the IC reactor has also gained successful experience. The wastewater from a chicory processing plant in Roosendaal, the Netherlands, has a COD of approximately 7900 mg/L, a SO42- concentration of 250 mg/L, and a Cl- concentration of 4200 mg/L. Using an IC reactor with a height of 22 meters and a volume of 1100 m3, the volume loading (based on COD) reaches 31 kg/(m3·d), with ηCOD > 80%, and an average retention time of only 6.1 hours [9].
   
Table 1 presents comparative results of IC reactor and UASB reactor treatment for typical wastewater. The data from the table indicates that the IC reactor largely addresses the shortcomings of the UASB, significantly enhancing the treatment capacity per unit volume of the reactor.

1．Anaerobic Fermentation Tank Principle, Detailed Description of Anaerobic Fermentation Tank Equipment, Detailed Introduction to Anaerobic Fermentation Tank, The process of biological degradation of organic matter, relying on the biochemical actions of facultative anaerobic bacteria and obligate anaerobic bacteria, under conditions of air exclusion, is referred to as anaerobic biological treatment or anaerobic digestion. This generally occurs in anaerobic tanks or anaerobic fermentation ponds.,Also known as anaerobic fermentation tanks, bio-fermentation tanks, etc.

2．Anaerobic fermentation tanks are primarily used to meet the living conditions of microorganisms, allowing them to thrive in a suitable environment.,To achieve vigorous fermentation and abundant gas production.

3．An anaerobic fermentation tank is a multi-stage internal circulation anaerobic reactor. It boasts high organic load, strong shock resistance, more stable performance, and simpler operation and management. The anaerobic fermentation tank is suitable for the treatment of slaughterhouse wastewater, and for the processing of animal manure from cattle, pigs, chickens, and other livestock, as well as for biogas production and power generation projects.;Urban waste sludgeSSA significant number of high-concentration organic wastewater treatment projects. 

Advantages of Anaerobic Fermentation Vats：

The anaerobic fermentation tank process can handle raw materials with high suspended solid content. The material inside the digester is evenly distributed, avoiding stratification and increasing the contact opportunities between the material and microorganisms. This allows the organic suspended matter on the liquid surface to circulate to the bottom of the reactor, gradually undergoing complete reaction, and avoids the accumulation of suspended matter on the liquid surface of the reactor.The "Insulation Cap Phenomenon" utilizes the excess heat from biogas generation to insulate and heat the external保温 system of the reactor, significantly enhancing the gas yield and investment efficiency. This also ensures the reactor operates normally throughout the year. The process is space-saving and cost-effective.
