7.A method of wastewater treatment, the method comprising the steps of:receiving a raw silicon processing wastewater in a wastewater storage tank;treating the received raw silicon processing wastewater with an acid fluid;measuring a pH of the raw silicon processing wastewater after treating with the...
when a treatment plant receives larger-than-normal amounts of untreated raw wastewater, a portion of the untreated wastewater must be diverted into a body of water, such as a river, in order not to exceed the amount of wastewater the plant was designed to handle. As discussed above, dischar...
During the treatment process, the maximum phosphorus removal rate is achieved during the early logarithmic growth phase of microalgal growth. Typically, phosphorus removal rates range from 1 to 7 mg/(L d) when initial phosphorus levels are between 4 and 20 mg/L. For instance, Chlorella displayed...

for plant cultivation, shifting the paradigm of wastewater management from treatment and disposal to reuse, recycle and resource recovery. In the context of a circular economy, where economic development is balanced with the protection of natural resources and environmental sustainability, wastewater ...
The wastewater treatment apparatus of the present invention has several advantages. First, the apparatus combines biotreatment, equalization, and clarification within single tank. This combination allows a more compact design (i.e, a smaller "footprint") for the treatment plant and decreases the facil...
