Comparative diagrams of the performance of coagulants
in removing turbidity (NTU) and TOC of samples:
My study indicates that clarification of turbid water with natural coagulants
from plant material (seeds) combined with use of solar radiation (on a black-painted roof for 8 hours) could provide a simple low-cost water treatment method for rural communities in Tanzania.
which were used here are divided into two groups: minerals and polymers.
Post-lime feed costs for the alternative coagulants
were based on estimated lime usage determined using the Rothberg, Tamburini, & Winsor Model for Water Process and Corrosion Chemistry, version 4.
Therefore, it can be envisaged that, the lime could be very useful for post disinfection of water treated with coagulants
prior drinking especially in poor households where drinking water is stored under unhygienic conditions.
The formation of the hydrolytic products formed from metal salt coagulants
occurred in a very short time and they are readily absorbed onto the colloid particles and then cause destabilization of their electrical charge.

While privatisation of Hungary's municipal water treatment system is driving demand for coagulants
and flocculants, robust economic growth and building projects for plants are key factors driving the demand in the Baltic States.
For instance, the entire structure of the water treatment market for coagulants
and flocculants will change as a direct consequence of the directive.
Frost & Sullivan says this increase in demand is expected to drive revenues in the market for coagulants
and flocculants from EUR 62.
