“…This was higher than 67% removal from wastewater using mixed algal cultures (Prathima et al, 2012). It was almost similar to other studies conducted where reduction was 90% (Kothari et al, 2013) in dairy effluent.…”

“…This was found to be higher than the mixotrophic cultivation yield of biomass of 0.8gm/L (Beevi et al, 2014), but was lower than the 3.1gm/L biomass yield of Chlamydomonas polypyrenoidium on dairy wastewater as measured on the 15 th day (Kothari et al, 2013). The biomass productivity of the algae was calculated to be 24.5 mg/L/day.…”

“…6, in the present study, total phosphates reduction after fifteen days was 64.7% and total reduction was seen to be 88.235% after 45 days. These results are higher as compared to 70% removal (Mahapatra et al, 2014), 72% removal (Wang et al, 2013), 70% removal (Kothari et al, 2013) in dairy effluent. But it was a little lower than phosphate removal in piggery wastewater treatment which was more than 90% within five days.…”

Nutrient pollution of wastewater and its treatment is currently one of the biggest challenges being faced in waste management in India. As nutrient pollution leads to eutrophication and algal bloom, the present research aims to reduce the nutrient load in wastewater using microalgae, before its release in water bodies. Microalgae was successfully isolated from municipal wastewater fed urban lake in Bengaluru and inoculated in domestic wastewater to carry out the treatment. Growth curve analysis and biomass studies were carried out on the microalgae isolated from lakes. The dry algal biomass was found to be 1.078gm/L and biomass productivity was 24.5mg/L/d. The nutrient removal efficiencies were found to be 33.33%, 66.66%, 80%, 88.88% and 88.235% for Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Nitrate Nitrogen and Total Phosphates respectively. Crude lipid extracted was 22.54% of the weight of dry algae.

“…Their study used a column photobioreactor with varying nutrient concentration and found that biomass productivity was different subject to several concentrations. Also, Kothari et al (2013) used dairy industry wastewater for the cultivation of Chlamydomonas polypyrenoideum on biodiesel production. Results indicated that dairy wastewater was a great medium for algae growth when 75% concentration was applied.…”

Abstract. The aim of this study was to compare the specific growth rate and biomass productivity of microalgae in domestic wastewater according to the initial cell concentration. The initial microalgae cell concentrations tested started from 10 3 cell/mL, 10 4 cell/mL, 10 5 cell/mL, 10 6 cell/mL, and 10 7 cell/mL under outdoor condition. The result revealed that the highest biomass productivity occurred at 10 6 cell/mL concentration with a value of 1.24 × 10 4 cell/mL/day, 0.26 day -1 of specific growth rate, and a doubling time of 2.63 days. Meanwhile, the lowest biomass productivity occurred at 10 3 cell/mL concentration with the lowest specific growth rate of 0.1 day -1 and the longest doubling time, which reached up to 7.14 day. As a result, the initial cell concentration of microalgae did influence the algal biomass productivity and growth rate differently. Thus, the maximum growth rate and biomass productivity were obtained at 10 6 cell/mL concentration which is recommended to be used in biotechnology industries and any wastewater treatment.

“…Actualmente el uso de microalgas en el tratamiento y reciclaje de aguas residuales ha atraído un gran interés debido a la generación excesiva de biomasa a un costo más económico y sin entrada adicional de nutrientes (Kothari et al, 2013;Amini et al, 2013), pero la aplicabilidad de los bioprocesos en la protección ambiental y los procesos de tratamiento de aguas residuales de la industria láctea se basan en investigar la forma en que los microorganismos actúan sobre el reciclaje de aguas residuales, la contaminación del aire y la recuperación del suelo. En este contexto, el modelado de bioprocesos de tratamiento de aguas residuales, especialmente de los procesos biotecnológicos utilizados para las aguas residuales y el tratamiento de residuos orgánicos se convierte en una necesidad (Román, Selisteanu, Sendrescu y Bobasu, 2011).…”

RESUMENEl objetivo de esta revisión fue consultar, analizar y concluir los principales tratamientos aplicados a las aguas residuales de la industria láctea. Las tecnologías que más se utilizan en el tratamiento de aguas residuales son los métodos biológicos y fisicoquímicos, así como también los microorganismos benéficos, microalgas, coagulantes, etc.; sin embargo, la digestión anaerobia es un proceso biológico que se aplica en este tipo de aguas, debido a que tiene mayor ventaja en comparación con los otros tratamientos en el mayor grado de estabilización y bajo crecimiento de biomasa. Se encontró que las aguas residuales presentan altos niveles de sólidos disueltos o suspendidos, que incluyen grasas, aceites y nutrientes tales como amoníaco, minerales y fosfatos.
