- Water Treatment
- 1. Collection – The source water for a municipal surface water treatment plant is typically a local river,
lake, or reservoir. There must be a method to get this water to the water treatment plant.
- 2. Screening and Straining – If you think about surface water sources, i.e., lakes, rivers, and reservoirs,
you realize they contain varying amounts of suspended and dissolved materials
- 3. Chemical Addition – Once the pre-screened source water is received into the treatment plant, chemicals
are added to help make the suspended particles that are floating in the water clump together to form a
heavier and larger gelatinous particle
- 4. Coagulation and Flocculation - A rapid mix unit is usually used where the coagulant is added to the
water to provide a very quick and thorough mixing
- 5. Sedimentation and Clarification – Once the flocculation process is complete, the water then passes over
the weir in the flocculator and travels to the center of the clarifier, or sedimentation basin
- 6. Filtration – Clarified water enters the filters from the top. Gravity pulls the water down through the
filters where it is collected in a drain system at the bottom of the unit
- 7. Disinfection – Once the water has gone through the filtration process, it is about as clear and clean as
it can get. However, there may still be bacteria and viruses remaining
- 8. Distribution – So how does the water come out of your kitchen tap? The stored water is pushed
through underground pipelines all over town in what is called a “distribution system”.

- Water
- Potable
- potable water, is water that is safe to
drink or to use for food preparation.
The amount of drinking water required
to maintain good health varies

- Pure
- Purified water is water that has
been mechanically filtered or
processed to remove impurities
and make it suitable for use

- pH
- pH is a scale used to specify how
acidic or basic a water-based
solution is. Acidic solutions have
a lower pH, while basic solutions
have a higher pH. At room
temperature, pure water is
neither acidic nor basic and has
a pH of 7

- Whats a settling Tank
- settling tank or clarifier, component of a
modern system of water supply or
wastewater treatment. A sedimentation
tank allows suspended particles to settle
out of water or wastewater as it flows slowly
through the tank

- Life Cycle Assesmet
- Life-cycle assessment (LCA, also known as life-cycle
analysis, ecobalance, and cradle-to-grave analysis) is a
technique to assess environmental impacts associated
with all the stages of a product's life from raw material
extraction through materials processing, manufacture,
distribution, use, repair and maintenance...

- Whats a Foculant?
- Flocculation, in the field of chemistry, is a
process in which colloids come out of
suspension in the form of floc or flake,
either spontaneously or due to the addition
of a clarifying agent

- Whats a graded sand bed?
- Pressure sand bed filters tend to be used in
industrial applications and often referred to as
rapid sand bed filters. Gravity fed units are
used in water purification especially drinking
water and these filters have found wide use in
developing countries
