Hygiene requirements are growing increasingly strict in many sectors, and the treatment of industrial wastewater is no exception. The vacuum distillation process in particular has to deal with the question of sterile treatment and subsequent storage of water obtained from the process. The mere possibility of reintroducing wastewater into the production process makes it imperative to prevent bacterial impurities.
The risk of bacterial impurities in industrial wastewater
In many industrial production processes,...
Two different air-cathode stacked microbial fuel cell (MFC) configurations were evaluated under continuous flow during the treatment of municipal wastewater and electricity production at a hydraulic retention time (HRT) of 3, 1, and 0.5 d. Stacked MFC 1 was formed by 20 individual air-cathode MFC units. The second stacked MFC (stacked MFC 2) consisted of 40 air-cathode MFC units placed in a shared reactor. The maximum voltages produced at closed circuit (1,000 Ω) were 170 mV for stacked MFC 1 and 94 mV for...
Ultraviolet (UV) light can be applied to support numerous applications in a broad range of industries. In commercial paint spray booths and label manufacturing plants, UV lamps are used to streamline paint jobs and the printing of logos. Outside of such practices, the light source may also be utilized to eradicate harmful, disease-causing bacteria. Systems that rely on the light’s ability to disinfect the surrounding environment (surface and air) are mostly found in food processing plants and medical...
Industrial Wastewater Treatment
Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time.
In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage Tanks accumulate waste often segregated as acid, alkaline, cyanide and hexavalent chrome-bearing which is transferred to a single...
What is APCr?
Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic operation of incinerators, modern ERF technology is now typically only applied to residual waste, i.e. municipal waste following...
