Napier Reid - a company trusted worldwide for over 55 years and having
over 2900 installations in over 25 countries, designs and manufactures
package water treatment plants (WTP) that combines rapid mixer, flocculator,
clarifier and filter.
Water enters the package water treatment plant and undergoes different
processes like coagulation, flocculation, clarification and filtration.
First, chemical is mixed in the raw water with help of rapid mixer, and
then gently agitated in a detention tank called the flocculation chamber.
After flocculation, the water flows into the clarifier. The clarifier
is a large chamber where the flow velocity of water is minimized. The
low velocities allow the particulate matter / floc to settle out of
suspension by gravity. This process is often aided by the addition of
tube or plate settlers.
Water flows by gravity into the filter that consists of porous media
(gravel / sand / garnet / anthracite / etc.) As the water flows through
the porous media, the suspended particles are entrapped and filtered out.
Filtered, clear water flows out from the outlet connection.
Napier Reid also designs and supplies the chlorination system or the
UV system required for disinfection.
