MANILA， May 19 (Xinhua) -- The Philippines' gross domestic product (GDP) growth in the first quarter of the year reached 6.9 percent， exceeding average consensus forecast of 6.6 percent， the country's socioeconomic planning secretary said Thursday.


Emmanuel Esguerra， also the director-general of the National Economic and Development Authority， said in a press conference that the first-quarter performance of the economy increases the likelihood of achieving the official GDP projection of 6.8 to 7.8 percent for full-year 2016， despite the weak agriculture and fishery sector.


Esguerra attributed the strong growth to increasing investment and construction， as well as gains in the industry and service sectors.


He pointed out that the external demand weakened， with growth of exports of goods and services slowing down to 6.6 percent.


In addition， the agriculture sector remains a poor performer. For the first quarter of 2016， the agriculture sector contracted by 4.4 percent， coming from almost stagnation the past year.


Esguerra said the economic growth in the coming quarters is promising， but the government should be wary of the downside risks.


"In particular， the agriculture and fishery sector will continue to reel from the lingering impacts of El Nino though the transition to a normal weather condition is already happening. We should also start preparing for the La Nina which now has a 75 percent probability of occurrence，" said Esguerra.

Waste water is any water that is affected by anthropogenic activity or activities of human beings. Domestic Waste water is made up of 40% from toilet flushing Nani Portugal Jersey , 30% from bathing, 15% from laundry, 10% from kitchen, and 5% from others. Waste water is made up of a lot of ingredients. One of the ingredients is water that is flushed from the toilet and other household activities. Other ingredients in waste water are:

Bacteria, parasitic worms Miguel Monteiro Portugal Jersey , and other pathogens
1. Hair, vomit, feces
2. Fruit sugar, drugs, and medicines
3. Sand Jose Fonte Portugal Jersey , metal particles, and ceramics
4. Animals such as small fish
5. Macro-solids such as children’s toys
6. Gases such as carbon-dioxide
7. Emulsions such as mayonnaise and paints
8. Toxins such as poisons
9. Pharmaceuticals

Waste water can come from a variety of sources such as:
1. Leakage from Septic Tank or Cesspit
2. Rainfall on the roof of buildings
3. Cleaning liquids and paints from domestic sources
4. Seawater coming into land
5. Waste from acid or alkali manufacture
6. Draining of storm water
7. Wastes from pesticide manufacture
8. Drainage from agricultural activities

Why must you treat waste water? Waste water must be treated to remove the pollutants in the waste water, to improve health and public hygiene, to preserve organisms in waterways, wildlife Joao Moutinho Portugal Jersey , and to improve quality of life.
The waste water treatment procedure consists of a series of steps.

Primary Treatment of Waste water: The primary treatment of waste water involves the removal of large objects from sewage. This involves removal of rags, grease, sticks, and floating objects. Preliminary treatment makes use of units such as screening, grit chamber Joao Mario Portugal Jersey , skimming tanks, pumps. Screening is used for removing floating matter. Grit chamber is used for removing sand and grits. Primary treatment involves the following processes – sedimentation, and also coagulation. Sedimentation is used to settle heavy solids under the influence of gravity. The Fundamentals of Engineering helps in knowing the primary treatment of waste water.

Secondary Treatment of Waste water: Secondary treatment of waste water includes biological treatment of water. This biological treatment removes the organic waste from the water. Microorganisms are used to convert solids that will not settle into solids that will settle. Secondary Treatment is used for waste water applications. The various systems for secondary water treatment are aeration systems, biological treatment systems, sludge and bio-solids processing system. Secondary treatment consists of the processes of activated sludge process Fabio Coentrao Portugal Jersey , oxidation ponds and lagoons, and trickling filters. The Fundamentals of Engineering Exam include the secondary treatment of waste water.

While treating waste water, the sewage in the water can be considered as a resource or it can be considered as a pollutant. There are waste water treatment plants that purify the water using physical, chemical, or biological methods. Fixed film systems Eliseu Portugal Jersey , trickling filters, sand filters, suspended film systems, activated sludge systems, and lagoon systems are also used in the secondary treatment stage.

Tertiary Treatment of Waste water: Tertiary treatment involves the removal of disease causing germs. This tertiary treatment is done through chlorination Eduardo Portugal Jersey , Ozone rays, Ultraviolet light, and hydrogen peroxide. Tertiary Treatment includes the following units and processes. They are membrane filtration and separation and disinfectant systems, reverse osmosis systems, Ion exchange Eder Portugal Jersey , activated carbon absorption, and physicalchemical treatment. The Fundamentals of Engineering Exam Prep cover all types of waste water treatment.

Circulation of Treated Water: The treated water is sent across the country either to drink, used in industry, or for medicinal purposes. Bungee Jumping is a favorite adventure for many travelers.
