HZIC Anaerobic Internal Circulation Reactor for Industrial High-Strength Wastewater Treatment
Product Details
HZIC Anaerobic Internal Circulation Reactor for High-Strength Wastewater Treatment
Introduction to the HZIC Anaerobic Reactor
The HZIC anaerobic reactor is a third-generation anaerobic treatment system developed from research on the Upflow Anaerobic Sludge Blanket (UASB) reactor. It uses a two-stage three-phase separator to divide the reactor into two zones: a high-load zone at the lower section and a low-load zone at the upper section.
The reactor relies on the density difference between biogas in the riser and downcomer tubes to create internal fluid circulation. This circulation continuously passes the wastewater through the anaerobic granular sludge bed, enhancing contact between the wastewater and the active biomass. As a result, the wastewater is rapidly purified with high treatment efficiency.
Key Features of the HZIC Anaerobic Reactor
Small Footprint
The HZIC reactor achieves high treatment capacity in a relatively small volume. The internal circulation design allows for much higher loading rates than conventional UASB reactors. For the same wastewater flow and strength, the HZIC reactor requires significantly less floor space.
High Volumetric Loading Rate
The HZIC reactor can operate at volumetric loading rates of 15 to 30 kg COD/m³·day or even higher, depending on wastewater characteristics. This is substantially higher than conventional UASB reactors, which typically operate at 5 to 10 kg COD/m³·day.
Strong Shock Load Resistance
The high biomass concentration and internal circulation provide buffering capacity against sudden changes in flow rate or organic strength. The reactor recovers quickly from peak loads that would upset conventional systems.
Stable Performance
The internal circulation maintains uniform mixing and pH distribution. This stability prevents acidification and ensures consistent effluent quality even under variable operating conditions.
High Biogas Production
The efficient conversion of organic matter to methane results in high biogas yield. The biogas can be recovered and used as an energy source, offsetting plant operating costs.
Simple Operation and Low Operating Cost
The HZIC reactor requires minimal operator attention once started. No mechanical mixing is needed; the internal circulation is driven by biogas. Energy consumption is very low compared to aerobic treatment systems.
Economic Benefits
Lower land requirements, reduced energy consumption, high biogas recovery, and minimal sludge production combine to make the HZIC reactor a cost-effective solution for medium- to high-strength wastewater treatment applications.
