The system may consist of a single pond or several ponds in a series, each pond playing a different role in the removal of pollutants. After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water ) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens ).
Later, during World War II, Germany used open ponds to increase algal cultivation for use as a protein supplement. [2] Some of the first experiments with the aim of cultivating algae were conducted in 1957 by the Carnegie Institution for Science in Washington. In these experiments, monocellular Chlorella were cultivated by adding CO 2 and some ...
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
They hypothesized the 100-times diluted sludge would the best solution to grow the algae. Results from the experiment showed the average mass of the 10-times diluted sludge was abnormal from the ...
The general steps of affixing paraffin sections can be concluded as 1. Clean the required slides, 2. Mark the cleaned slides, 3. Drop affixative on each slide, 4. Put on another slide, 5. Spread the affixative, 6. Drop floating medium, 7. Divide the paraffin into required length, 8. Transfer the sections, 9.
An algae scrubber is a water filtering device which uses light to grow algae; in this process, undesirable chemicals are removed from the water. [1] Algae scrubbers allow hobbyists to operate their saltwater or freshwater tanks or ponds using natural filtration based on primary production, much as occurs in oceans and lakes.
