Municipal Sewage Plant
For municipal sewage plant, especially in the densely populated area of the central city, "Land occupation" is one of its main problems, Hanqi seeks compacted programme: solving the problem with conventional physicochemical and biofilm technology.
A technology that combined of aeration, sand grit, oil removal, and clarification of inclined tube. With the characteristics of no chemicals adding, low land occupation, and high efficiency. Especially adapt as pretreatment of MBR and BAF.
The effect of sludge backflow and internal circulation system in the reaction zone is forming large, density and uniformity flocs, and achieving faster separation of mud and water. Flow velocity: 15-25m/h.Using: tight land occupation; high pollution concentratant of raw water; pre-treatment as chemical strengthening; combined application with BAF.
A kind of biofilter that adopts with irregular crushing medias, the larger specific surface area leads to a larger biomass per unit volume. A variety of forms and combinations like carbonization, nitrification and denitrification can be chose flexibly. We make the filter plates with the method called "Two-Step", which can help ensure the construction flatness and reduce difficulty, shorten the time limit.
BFR® Moving Bed Biofilm Reactor
BFRis modified MBBR, which is usually designed for reconstruction of biological system. We can expand the scale without changing the original tank capacity, and upgrade the index including COD, NH3-N, TN and TP to a higher standard.
Biofix® NDN Biofilter
Biofixfixed bed biofilter different
The effect of sludge backflow and Internal circulation system in the reaction zone is forming large, density and uniformity flocs, and achieving faster separation of mud and water. Flow velocity: 15-25m/h.
Loading flocs onto medias(micro sand) greatly speeds up the separation of mud and water. We can recycle and reuse the medias by a hydrocyclone. The velocity is 40-60m/h, which is suitable for land occupation limited situation; phosphorus removal; suitable for quality improvement and capacity expansion of existing water plants.
