Job offers PhD thesis on biomass from algae In the future, biofuels and animal feed could be produced with microalgae, the theoretical potential is high. They show high biomass productivity, can use CO2 from flue gases and can be cultivated on areas that are unsuitable for agriculture.
Among them are chemical, physical and biological treatment. Research of microalgae as a solution for wastewater treatment has gained importance in recent years. It is because microalgae require inexpensive substrate which can be found vastly in wastewater, carbon dioxide and solar light. Present review of biological treatment of wastewater by microalgae only covers municipal and agriculture related to animal manure waste.
However, biological treatment by microalgae of palm oil mill effluent POME scarcely being reviewed. POME contains organic waste, heavy metal, ammonium, phosphorus etc.
Previous review shown, microalgae have the capacity to reduce chemical oxygen demand CODheavy metal and other substrate value. Addition to that, microalgae also produce biomass that can potentially be used as other product such as bio-fertilizer, animal feed etc.
This review investigates several methods for culturing different strains of microalgae in wastewater. Introduction crude palm oil production is liquid sludge waste also known as palm oil mill effluent POME .
Water pollution has become a problem to This waste is rich in organic matter and highly humankind since the beginning of industrial polluting; for every FFB processed, 0.
POME is thick rivers, lakes and oceans which later interrupts the brownish colloidal suspension and released natural recycling process such as photosynthesis, unpleasant odour. This waste is rich in organic respiration, nitrogen fixation, evaporation and matter and highly polluting.
POME is generated precipitation. Therefore, wastewater treatment from 3 main process of crude oil production; plays a major role today to make we live in sterilization, clarification and nut cracking healthy environment and ensure the security of process. Like a palm oil mill, large-scale production of For the last decade Malaysia has been known wastewater is likely to consequence of all health as a leader in producing palm oil product.
Experiment resultsshowed that the activity of the microalgae separated from the lake rock attachments was thehighest of several samples, and the Aquatic VI culture medium was the most effective culturemedium for freshwater mixed microalgae cultivation. This thesis presented microalgae as the third generation biofuel feedstock. it has possibility Whether and feasibility to replace the fossil fuel in future was discussed. Microalgae play an important role in this regard, as they have promising characteristics as potential raw material for the production of biofuels, able to absorb large amounts of CO2.
Based effect to the societies. It has treated prior to disposal into streams, lakes, seas been reported that production capacity of and land surfaces. Wastewater treatment can be approximately 89 million tonne of fresh fruit classified into three groups which are physical, bunch FFB per year and revenue generated by chemical and biological treatment.
The main by-product in resources on a global scale Lau et al. Jordan International Energy Conference - Amman This is global problem that can be solved by the minimal land requirement, producing lipid used of microalgae which the wastewater is used content biomass which can be utilized for as feed for the microalgal growth.
The advantage biodiesel production and using wastewater is that while microalgae is removing the nutrient bodies as nutrient feed with no herbicides and from the wastewater and at the same time pesticides. The use of wide 2.
For example raw or treated exposed with microalgae shows a rapid decrease POME mostly contains extremely high content in level of metals, nitrates and phosphate of degradable organic matter.
POME contains for some times. POME can wastewater treatment solution. Oil exposure because of its ability to become a new content of POME can be found in two phase source of renewable energy.
Microalgae offer a which is either suspend in supernatant or float on great potential for exploitation especially in the upper layer of the suspension. Physical, production of biodiesel and other product. Some chemical and biological methods are used today of the main characteristic which set microalgae to remove contaminants from wastewater.
The not only for the biomass production for biodiesel main goal of wastewater treatment management are that microalgae do not require agricultural is the protection of the environment and the land, freshwater is not essential and nutrients can public health by protecting the water bodies be supplied by wastewater and CO2 by which provide important water resources.
The main advantages of 1 shows the composition of untreated domestic utilizing microalgae for wastewater treatment are wastewater levels. The fields are microalgae successfully, good algal growth and wastewater temperature, the colour, and the the factors that affect the growth must be odour release by the wastewater.
The growth rate of algae is wastewater is important because it affects influenced by physical, chemical and biological chemical and biological reaction in wastewater.
Temperature is also very important in determination other parameters such as pH, 3. The colour of wastewater plays as indicator of the age The need to supply mineral nutrients and other of wastewater.
Moreover microalgae undergo growth requirements to algae growth is essential. The most common wastewater treatment. Odour presents in elements for algal cell is ChO45N16P and for wastewater is caused by dissolved impurities optimal growth of microalgae, medium should be cause by decaying aquatic microorganism and prepared by this proportion.Goal: In her PhD thesis, Marjukka Lamminen studies the use of microalgae as a protein feeds for dairy cows.
The high protein content, rapid growth and high productivity of microalgae make them a. This thesis advances knowledge in the field of microalgae biodiesel research. The work has developed a methodology for screening microalgae species and for ensuring that the biomass is suitable for biodiesel production.
This thesis is based on a research question that came up in his work and he spent many hours teaching me the ins and outs of microalgae cultivation as well as helping with the setup of the experiments and the data collection.
Microalgae is a biofuel crop that needs large amounts of water and nutrients in cultivation stage and requires excessive energy at the downstream processes. Cultivation of microalgae: effect of light/dark cycles on biomass yield Marcel Janssen ˘. This thesis is organized into four chapters. Chapter 1 provides an introduction to the benefits of extracting lipids and carotenoids from microalgae and the objective of this thesis.
