Treatment of Waste Water from Domestic, Agriculture and Industry

Household / agricultural / industrial wastewater treatment Main contaminants from household wastewater: - Suspended solid - Soluble solid - Precipitable solid - Inorganic substances (mineral, heavy metals, cadmium, calcium, copper, lead etc.), magnesium, nickel , Potassium, sodium, zinc) - Organic - Nutrients (eg nitrogen, phosphorus) - Oils - pathogens (eg bacteria, viruses, parasites) Major pollutants in agricultural drainage: - suspended solids - dissolved solids - Sexy solid - inorganic substances (like

In Trinidad and Tobago, water is mainly used for domestic, agricultural, industrial use, and our main pollution sources are related to them. Home - untreated sewage and solid waste (waste), agriculture - from fields and crops including fertilizers and pesticides. Industry - water treatment, solid waste, lubricant, chemicals and oil spills. Article 29 (1) (j) (Chapter 61, Chapter 02) of the Petroleum Act stipulates the formulation of regulations to prevent water pollution and compensation. Article 3 of the oil regulation established pursuant to Article 29 (1) (j) of the Petroleum Act outlines the crime of oil contamination. Section 42 (2) (c) of "Oil Regulation" requires permission to take precautionary measures to avoid tide river pollution. Part 2 of the oil Article 11 (Test, storage etc.)

Agriculture is one of the domestic water pollution sources in the country. Industrialized agricultural management often releases large quantities of water and waste from crop production and livestock, causing water shortages and harmful pollution in nearby areas. The main causes of this contamination are as follows. Nutrients: The US Environmental Protection Agency ranks nutrient pollution as one of the most difficult environmental problems. Nitrate is a common ingredient of fertilizer and it can cause serious harm to infants when present in drinking water. According to the 2010 US Geological Survey (USGS) report in 2004, 64% of the shallow wells investigated in urban and agricultural areas contained a lot of nitrates. Excessive nutrients hinder the growth of aquatic plants and may kill fish. Reproduction of this algae will produce blind spots such as those caused by nitrogen fertilizer used in farmland in the Mississippi Valley, as seen in the Gulf of Mexico.
