Ziziphus mauritiana is a hardy tree that copes with extreme temperatures and thrives under rather dry conditions with an annual rainfall of 6 to 88.5 in (15–225 cm). In Fiji, sometimes naturalised Ber trees grow along roadsides and in agricultural land, usually near sea level but occasionally up to an elevation of about 600 m.
Jujube (UK / ˈ dʒ uː dʒ uː b /; US / ˈ dʒ u dʒ u b / or / ˈ dʒ u dʒ ə b iː / [5]), sometimes jujuba, scientific name Ziziphus jujuba, and also called red date, Chinese date, and Chinese jujube, [6] is a species in the genus Ziziphus in the buckthorn family Rhamnaceae.
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
Portable water purification devices and methods are available for disinfection and treatment in emergencies or in remote locations. Disinfection is the primary goal, since aesthetic considerations such as taste, odour, appearance, and trace chemical contamination do not affect the short-term safety of drinking water.
Ziziphus / ˈ z ɪ z ɪ f ə s / [3] is a genus of spiny shrubs and small trees in the buckthorn family, Rhamnaceae. It includes 68 species native to tropical and subtropical Africa, Eurasia, and Australia and tropical South America. [ 1 ]
Ground water remediation techniques span biological, chemical, and physical treatment technologies. Most ground water treatment techniques utilize a combination of technologies. Some of the biological treatment techniques include bioaugmentation, bioventing, biosparging, bioslurping, and phytoremediation.
However, coagulation and flocculation can be used for building a compact treatment plant (also called a "package treatment plant"), or for further polishing of the treated water. [ 17 ] Sedimentation tanks called "secondary clarifiers" remove flocs of biological growth created in some methods of secondary treatment including activated sludge ...
Advancements in water treatment technology have affected all areas of industrial water treatment. Although mechanical filtration, such as reverse osmosis , is widely employed to filter contaminants, other technologies including the use of ozone generators, wastewater evaporation, electrodeionization and bioremediation are also able to address ...
