The ,Filtration, Model The ,filtration, of suspended and colloidal particles from a water or ,wastewater, can be considered as involving two separate and distinct steps: (i) the transport of the suspended particles to the immediate vicinity of the filter grains, and (ii) the attachment of the suspended particles to the filter grains or to another particle which has previously been deposited

7/1/2020, · ,Wastewater, was prepared as growth medium by autoclaving after ,filtration, through filter paper with ca. 10 μm pores, provided by Munktell AB (Sweden). Algal harvesting and experimental setup Cultures of each strain were harvested in exponential growth phase by centrifugation (6 min, 3700 g ), washed repeatedly with the treated ,wastewater, medium, and resuspended in it.

A more promising alternative for ,wastewater, remediation is the combination of the activated sludge treatment with membrane ,filtration, process. This technology, also known as membrane bioreactor (MBR), differs from CAS since a membrane module is used instead of the secondary clarifier to separate activated sludge from the final effluent ( Xing et al., 2000 ).

The performance of catalytic ozonation in the removal of organic contaminants from actual petrochemical ,wastewater, was studied using iron‐nickel foam as catalyst (Huang, Luo, Xu, Zhang, & Li, 2019). Catalytic ozonation not only improved the biodegradability of the petrochemical ,wastewater, but also enhance the removal of nutrients and heavy metals.
