Optimization of some independent process variables (inoculum size, palm oil mill effluent concentration, light intensity, agitation and pH) by response surface methodology (RS M has been reported by Jamil et al. [ 47].
As expected, less H2O2 photolysis occurred in municipal wastewater effluent due to light screening.
The effect of wall reflection of the light on effluent log inactivation was also investigated under different water qualities and lamp power conditions.
Well-mixed photobioreactors with algal biomass recirculation are recommended to protect the microalgae from effluent toxicity and optimize light utilization efficiency.
The effluent gas compositions include light hydrocarbons (C1 C5, H2, CO, CO2, H2S, etc).. Based on the results from literatures, it shows that THAI CAPRI process has the potential to convert heavy crude oil to almost light crude oil in a single step, without further surface upgrade required.
This research represents an important advance in the synthesis of novel co-doped oxides for the photocatalytic degradation of organic pollutant under visible light irradiation for industrial effluent.
Besides the anti-aesthetic effect produced in the effluents, the coloration reduces the solar light transmittance, affecting the aquatic organisms' photosynthetic activity (Michniewicz et al. 2008).
For examination by light microscopy, samples of ileal effluent were immersed in Karnovsky's fixative (1.6% formaldehyde and 2% glutaraldehyde; 0.08M sodium cacodylate; pH 7.2), and left to fix at room temperature for at least 24 h.
By contrast, above mentioned VFAs in effluent can be further utilized by microalgae without light for lipid production and energy recovery, whereas so far related research on this field was lacking.
The degradation of the pharmaceuticals was then evaluated when present in an effluent from sewage treatment plant (STP) under black-light irradiation.
