Plankton Organisms

Generally the presence of plankton in the water will be influenced by the type of waters (running and stagnant), quality of the chemistry and physics of water (eg, temperature, brightness, flow, pH, CO2 content is free, the content of nutrients), and their competitors and or predators of plankton. In the stagnant waters (eg, ponds, swamps, lake, lake), the presence of ...

Organisms Bentos

The existence of benthic animals on a body of water, is strongly influenced by various environmental factors, both biotic and abiotic. Biotic factors that influence them is a manufacturer, which is a food source for benthic animals. The abiotic factors are physical-chemical water such as: temperature, flow, dissolved oxygen (DO), biological oxygen demand (BOD) and chemical (COD), and the amount ...

Viscosity Water Physics

The viscosity of water is the physical properties of water that should not be overlooked. This is a result of friction caused by the arrest of a liquid substance on moving objects. The amount of friction is proportional to the prisoners: a) The surface area of ​​objects associated with water. b) The speed of motion of a body. c) The ...

Parameters Biology

Biological parameters was rarely used as a parameter determining the pollution. In fact, measurements using physical and chemical parameters only provide momentary environmental quality and tend to give results with interpretation in a wide range. Today some developed countries such as France, Britain and Belgium glanced biological indicators for monitoring water pollution. Even already developed biotic water quality laws. In ...

The Influence of pH Brought Water

Water pH affects the fertility waters because it affects the lives of microorganisms. Acidic waters will be less productive, can even kill domestic animals. At low pH dissolved oxygen content is reduced, as a result of decreased oxygen consumption, decreased respiratory activity, respiratory activity rose and appetite will decrease, the opposite occurs in alkaline conditions. On this basis, the aquaculture ...

Oxygen Levels and Solubility

Decreased levels of oxygen. Basically the process of reduction of oxygen in the water caused by the process of chemistry, physics and biology, namely:  The process of breathing (respiration) either by animals or plants.  The process of decomposition (decomposition) of organic material.  Basic waters are reducing. The basis of these waters can only be covered by only ...
