Sedimentation Equipment
High-Density Sedimentation Tank
In scenarios such as water supply purification, advanced wastewater treatment, and hardness and fluoride removal from industrial wastewater, traditional sedimentation tanks often fall into the dilemma of "large footprint, low surface loading rate, poor effluent quality under low-temperature and low-turbidity conditions, and high moisture content in discharged sludge." The high-density sedimentation tank launched by Rihong Environmental integrates rapid mixing, mechanical flocculation, inclined tube (plate) separation, and external sludge circulation and thickening into a single tank. With the "dense floc core" formed by high-concentration sludge return, it operates stably at a surface loading rate far higher than that of conventional sedimentation, producing clear effluent with minimal sludge discharge. It is an ideal choice for upgrading and new construction projects.
Microsand Sedimentation Tank
Traditional sedimentation tanks often fall into the dilemma of "large footprint, low loading rate, and unstable effluent under low-temperature low-turbidity and high-turbidity shock conditions." Rihong Environmental's Microsand Sedimentation Tank doses microsand as high-density floc "seed crystals," enabling flocs to rapidly densify and settle extremely fast, achieving efficient solid-liquid separation within a very short retention time—at the same effluent standard, the footprint is only a fraction of that of traditional sedimentation tanks, making it an ideal choice for upgrading and capacity expansion as well as high-turbidity water source purification.
High-Density Rapid Sedimentation Water Treatment Equipment
When facing water treatment scenarios with high turbidity, high suspended solids, low temperature and low turbidity, or limited land availability, the traditional problems of conventional coagulation and sedimentation—"low surface loading rate, bulky tank volume, slow start-up"—are always unavoidable. Rihong Environmental's High-Density Rapid Sedimentation Water Treatment Equipment (also known as micro-sand sedimentation tank, Actiflo-type ballasted sedimentation) uses fine quartz sand as the "weighting skeleton" of flocs, combined with high-speed inclined tube separation and micro-sand cyclone recovery and circulation. The surface loading rate can reach several times that of traditional sedimentation, allowing the sedimentation tank to "slim down by half while producing more stable effluent," providing a compact and efficient technical route for wastewater treatment plant upgrading and capacity expansion, stormwater overflow treatment, and industrial high-turbidity wastewater.
Inclined Tube Settler
Traditional horizontal sedimentation tanks often fall into the dilemma of "large footprint, low loading rate, and unstable effluent under low-temperature and low-turbidity conditions." The inclined tube settler directly applies "shallow pool theory"—by installing honeycomb inclined tube media at a 60° inclination in the sedimentation zone, the settling path of particles is shortened from several meters to less than one meter. The surface loading rate is increased by 2–3 times compared to ordinary sedimentation tanks, and the footprint is reduced by more than half, while retaining the advantages of simple structure, low investment, and easy operation and maintenance. It is the most widely applied mature equipment in the field of water supply and wastewater clarification.
