Sewage Polluted Water Treatment via Chitosan: A Review

image

Due to the increasing scarcity of water, wastewater treatment and water conditioning are one of the major future issues. Together with the need to apply highly accessible abundant materials and the demand to replace fossil-based chemicals with sustainable compounds from renewable resources, chitosan (CS) provides some of the solutions to obtain these goals and combines both, abundance and sustainability. Hence, the focus of this review is on the application of CS in wastewater treatment providing advantages and drawbacks in using CS in contrast to chitin. We herewith present the application of CS for coagulation/flocculation purposes, whether as native compound, as functionalized molecule or as blend, respectively, composite. The heavy metal, respectively, dye removal is an additional theme to be addressed in the body of the text. The third topic of this review contains the application of CS blends or composites in order to prepare membrane materials for water purification or conditioning. Together with a summary of the recent study, we discuss these findings and possible consequences for future works. In addition, we provide some theoretical background of the processes that CS is involved in and state some mechanistic insights.

GAB Equation | Moisture Sorption Isotherm Modeling

Get to know how to use the Guggenheim-Anderson-de Boer (GAB) Equation for modeling of moisture sorption isotherms! The GAB Equation is suitable for modeling many food materials in a wide water activity range. Unlike BET, the workable range for the GAB model is from zero to 0.9. This is recommended by the European Project Group COST90 for the mathematical estimation of moisture content. I personally studied this lesson in my graduate class and I had a hard time learning this. I created this video so that you can easily learn how to calculate this equation. We’ll have a sample computation in this video. I’ve included the .xlsx file that I used in this video so that you can also learn this quickly. 3 posts - 2 participants Read full topic https://fstdesk.com/t/gab-equation-moisture-sorption-isotherm-modeling/4568

Phytochemistry of guava fruit

Guava ( Psidium guajava ) Fruit Phytochemistry and Nutritional Significance Economic Importance The fruit of guava is very rich in Vitamin C, which is substantially higher than what is found in citrus. It is also a good source of Vitamin A and other important elements. The fruit contains a large amount of citric, lactic, malic, oxalic and acetic acids and a trace amount of formic acid. The ripe fruit is usually eaten as a dessert. It can also be utilized in many ways for making jellies, jam, paste, juice, baby foods, puree, beverage base, syrup, wine and other processed products. It may be eaten sliced with cream and sugar and as ingredient in cakes and pies. It is also used in dishes like “sinigang”. Some parts of guava tree have medicinal and commercial usefulness. The bark and leaves are used in childbirth to expel the placenta. The leaves can be made into tea and astringent decoction can cure stomachache and act as vermifuge. When crushed or chewed, it is used for toothache t...
