nutrients (nitrogen and phosphate)

• N-Nitrate and Nitrite N-N-artificial fertilizers.
• N-Phospate household detergent.
• N and P food, etc.
• Phospate organic chemical reactions (40%) and Dissolved Orthophospate (60%).
• Total Nitrogen Organic Nitrogen (60-65%), Ammonia (35-40%), Nitrate and Nitrite Nitrogen.
• Nitrogen and high levels of lead Phospate Phytoplankton growth (algae) that excessive that a lake can be eutrophication.

Negative Aspects of Eutropikasi

• Fish die due to potential fluctuations Oxygen levels : 1) 0 ² = 5 mg / l, fish go from there.;2) 0 ² = 2 mg / l, fish die (turn into an anaerobic environment).
• The occurrence of odor problems at night.
• Ecosystem becomes unstable.

PATHOGENIC

In developing countries there are about ± 80% of the disease be transmitted through the medium of water. It is caused by several bacteria viruses and protozoa such as:

• Coliform Faecel
• Vibrio cholerae
• Hepatitis A
• Giardia lamblia

According to research there are various types of microbial pathogens in wastewater, for example:

• 10 types of viruses, eg, viral hepatitis A virus and adenovirus
• 8 types of bacteria, eg, bacteria E-coli and bacterium vibrio cholerae
• 3 types of protozoa, eg, protozoa Entamoeba histolytica
• 8 types of worms, eg, worms Fasciola hepatica

. INDUSTRIAL WASTE WATER

• Some types of pollutants that can be derived from Industrial Waste Water, as follows:
• Heavy metal (steel plant)
• Detergent (Textil Factory
• Pathogens, viruses (Hospital)
• Pesticides, Insecticides (Chemical Plant, Food, Textile)
