Waste Water Treatment: State-of-the-Art System for Efficient Contaminant Removal_1
Waste Water Treatment
This state of the art water treatment system entails storage pool, a horizontal flow grit chamber, a
skimming tank, a sequencing batch reactor, a chlorine contact tank, a sludge thickener, and
sludge drying beds.
Storage pool
The storage ponds are rectangular or cylindrical depressions designed for the purposes of
removing pathogens and organic waste from the raw water being treated. These ponds are
usually over 3m deep to increase the retention time of the water and thus encourage sludge to
settle at the bottom of the pond. These ponds are designed such that the influent is allowed to
enter the pond from one point of the pond and stay in it for a number of days before exiting
through another point as effluent (Zuriaga-Agustí, 2011, p. 319). The ponds are able to reduce
the total suspended solids (TSS) as they tend to settle and be scrapped off the bottom of the pool
using sludge rakes. Scum, which floats on the surface of the raw water, may also be easily swept
off in the process to aid in reducing the total amount of oil and grease in the waste water.
The Manual Fine Bar Screen
The screen works to ensure that the effluent coming from the storage pond is mechanically or
manually separated from the fine solids suspended in the raw water to effectively reduce the
quantity of sludge to go through the treating process. In so doing, the manually cleaned screens
are able to reduce the problems of clogging expected further down in the treatment process.
Horizontal Flow Grit Chamber
This chamber is designed to reduce the horizontal flow rate of the water throughout the system in
order for the suspended solids to settle and improve the efficiency of being removed from the
raw water. This chamber allows the removal of particles that can cause wear and tear of the
wastewater treatment system in the event that they continue in the process. This chamber allows
the materials to settle down and be easily removed.
Skimming Tank
This tank allows for all the floating materials like grease and oil to be removed from the water
after it rises and settles on the surface of the wastewater. During the skimming process a
skimmer is used to skim off the floating scum as the raw water continues to flow into different
partitions of the skimming tank. The scum is removed so that it does not interfere with the
activated sludge treating process in the SBR tank.
SBR Tank
The SBR tank allows for the wastewater to be treated in batches and reduce the amount of
organic matter in the raw water through the activated sludge process where oxygen is bubbled
