Primary Wastewater Treatment: Physical Process

Following preliminary treatment, sewage water is pumped into the primary sedimentation tank. In this tank, the sedimentation of suspended solids and organic matter occurs. Approximately 50-70% of the solids settle down, leading to a reduction of about 30-40% in coliform organisms.

The organic matter that settles is called primary sludge, which is then removed by mechanically operated devices. The supernatant (effluent) remaining in the primary sedimentation tank still contains significant amounts of dissolved organic matter and microorganisms, which are subsequently removed during secondary treatment.

In 2001, James O’Neill of Goldman Sachs authored a paper titled “Building Better Global Economic BRICs.” The BRICs acronym in the title referred to:

• Brazil
• Russia
• India
• China

These nations are reshaping the international economy with the potential to transform global trade and capital flows. BRICs are large economies, ranking among the world’s top 10 in population and top 11 in GDP. They have undergone reforms that have transformed them, making them more internationally integrated and central to the future of the world economy.

In 2010, these countries accounted for approximately 41 percent of the world’s population and 25 percent of world GDP when measured in PPP terms.
