Effect of O3 and O3/H2O2 on algae harvesting using chitosan
We examined the effects of pre-oxidation using ozone (O3) and a combination of O3 and hydrogen peroxide (O3/H2O2) on algae suspensions and their harvesting. Inactivation of algae cells, release of intracellular organic matter (IOM), mineralization of extracellular organic matter (EOM), and changes in molecular weight distribution of EOM were found after pre-oxidation. Enhanced separation ...

Rhodomonas
Have you ever come across a beautiful reddish (and pink in my opinion) coloured algae? That algae may have been rhodomoas, one of our favourites! Why use Rhodomonas for feeding oysters and other aquatic animals? Particle Size Rhodomonas algae have medium cell sizes, which makes them an ideal food source for oyster larvae. The cells are well-suited for the small filtering apparatus of young ...

Light Intensity
Microalgae Growth – Light Intensity If light is one of the key ingredients in photosynthesis, will more light always generate more productivity? Not exactly. Microalgae growth tends to have a consistent relationship with light intensity. Though the actual growth rates and intensities for different points in this curve will vary depending on many factors the general shape is consistent ...

Toxicity of ZnO nanoparticles to the copepod, Acartia tonsa, exposed through a phytoplankton diet
Zinc oxide (ZnO) nanoparticles (NPs) are being increasingly utilized in a variety of products and applications and are therefore commonly discharged into aquatic environments, increasing exposure and potentially impacting aquatic organisms. ZnO NPs can depress growth of some marine phytoplankton, and several examples of NP trophic transfer have been documented, although not within planktonic ...

Investigation of initial pH effects on growth of an oleaginous microalgae
Chlorella sp. HQ for lipid production and nutrient uptakeUsing microalgae for synchronous biodiesel production and wastewater treatment is a promising technology. The growth, lipid accumulation and nutrient uptake characteristics of an oleaginous microalga Chlorella sp. HQ were evaluated at different initial pH from 5.0 to 11.0. The pH values changed towards neutrality and ended in the range 6.0–9.0 without artificial control. The alkalinity ...

The treatment of (fish) ponds on an environmentally friendly manner with the usage of the LG Sonic case study
Aquaculture, or aqua farming, is the cultivation of aquatic organisms, such as fish or shrimps, in a controlled environment. Where this happens in a closed water container, algae may occur that pollute the water and may damage the organisms grown. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these. LG Sonic uses ...

The role of a hybrid phytosystem in landscape water purification and herbicides removal
The performance of a hybrid phytosystem in landscape water purification and herbicides removal was investigated. The phytosystem operating in an arboretum is located in the Minhang Campus of Shanghai Jiao Tong University, China. The phytosystem is composed of two purification stages: sedimentation Stage 1 without external air supply; and Stage 2 with an external air supply. Stage 2 is also ...

Lg Sonic Ultrasonic Algae and biofilm control for irrigation case study
Water used for irrigation can contain high levels of nutrients, some of these nutrients are beneficial for the plants watered, but can also lead to extensive algal growth. Algae in irrigation tanks can clog the irrigation system and can also be spread over the irrigated area. In addition, some types of fungus, also present in these waters, can be harmful for the plants grown. Therefore the ...

LG Sound, controlling algae in irrigation reservoirs
Algae growth in irrigation water can cause a serious problem. Algae in irrigation tanks can clog the entire irrigation system, such as the pumps, filters, drip-installation and sprinkler nozzles. Besides that the algae and their by-products can also be spread over the irrigated area. In addition, some types of fungi, also present in these waters, can be harmful for the plants grown. Typical ...

Photobioreactors: Advantages & Disadvantages
What are open and closed algae culture systems? The two broadest methods of culturing algae at medium to large scale are split into two styles of system: open and closed photobioreactors (PBRs). A PBR is any device or system that supports the culture of photosynthetic organisms using light. There are photobioreactor advantages and disadvantages to both types systems depending on the goals you ...
