IC Anaerobic Reactor Tower

When treating medium- to high-strength organic wastewater, the goals of "high loading, small footprint" must be balanced with stable operation and energy recovery—yet conventional UASB is already approaching its loading limit. The IC (Internal Circulation) anaerobic reactor is built around a "high height-to-diameter ratio tank + two-stage reaction chambers + biogas-driven internal circulation." Using biogas production as the driving force, it forms a sludge-water circulation inside the reactor, greatly improving mass transfer efficiency and volumetric loading. It is the preferred high-efficiency anaerobic equipment for industries such as brewing, starch, papermaking, and chemicals.

Microsand (High-Rate Ballasted Sedimentation) Clarifier vs. Conventional Clarifier vs. High-Density Clarifier: How to Choose?

All three are "coagulation + solid-liquid separation," but they differ in positioning, footprint, and investment. The key to selection is not "which is best," but "which best fits your constraints" — limited land? Need rapid startup? Or budget-sensitive? The table below lays out the differences clearly.

Which Industries Are Microsand (High-Rate Ballasted) Sedimentation Tanks Suitable For? Analysis of Seven Typical Application Scenarios

The strength of microsand (high-rate ballasted) sedimentation tanks lies in "rapid removal of suspended solids and colloids, chemically enhanced phosphorus removal, and efficient solid-liquid separation in space-constrained settings." Wherever the conditions involve "high turbidity, high SS, phosphorus removal requirements, limited land, and need for rapid startup," it is typically a priority candidate. The following seven categories are the most typical deployment scenarios.
