Starch wastewater treatment technology Product Details Technical Highlights: This process employs an anaerobic-aerobic biological treatment method for high-concentration organic wastewater. The anaerobic treatment unit utilises the UASB (Upflow Anaerobic Sludge Blanket) process, whilst the aerobic treatment employs the SBR (Sequencing Batch Reactor) process. Following anaerobic treatment, the refractory CODCr in the wastewater is converted into…

Membrane Bioreactor (MBR) Technology for the Treatment and Reuse of Domestic Wastewater Product Details The Membrane Bioreactor (MBR) process represents an organic integration of biological wastewater treatment technology and membrane separation technology. After biological treatment within the reactor has broken down and converted organic pollutants, microfiltration (MF) or ultrafiltration (UF) membranes are used to separate…

Anaerobic internal circulation (HZIC) reactor Product Details Introduction to the HZIC Anaerobic Reactor The HZIC anaerobic reactor is a third-generation anaerobic reactor developed on the basis of research into Upflow Anaerobic Sludge Bed (UASB) reactors. It utilises a two-stage, three-phase separator to divide the reactor into a high-load zone at the bottom and a low-load…

Tannery Wastewater Treatment Technologies Product Details Sulphide wastewater: Following MnSO₄-catalysed oxidation, a desulphurisation aid is added and the pH is adjusted to neutral. After precipitation, the removal rates for CODcr and BOD₅ are 70–80%, whilst the removal rate for sulphides exceeds 97%. Chrome tanning wastewater: The pH is adjusted to 8–8.5 to precipitate chromium in…
