Nutrient removal . nitrification / denitrification, phosphorous removal. Turbidity is a measure of . water clarity, how much the . material suspended in water. decreases the passage of light. through the water. . It is an optical characteristic of water and is an expression of the amount of light that is scattered by material in the water when a light is shined through the water sample. . nanocomposites. in water treatment.

Suspended load. : Sediments that move primarily suspended in fluid flow but may interact with bed load and is comprised primarily of silts and clays and sometimes sand. Suspended load has a continual exchange between sediment in fluid flow and on the bed as it is constantly being entrained from the bed and suspended while heavier particles settle out from the flow to the bed. .

Department of Civil, Structural & Environmental Engineering. Unit 1. By: Sarmad Rizvi. Introduction. General Perception of Chemical Engineering is to, “convert or separate raw materials into useful products.” How?. Some processes and industries where chemical engineering is essential:. is the provision of water for consumers (domestic, trade, public) via a system of facilities (pumps, aqueducts, reservoirs and water treatment units) . H. umans need water for cleaning, toilet flushing, and bathing, so normally a minimum of 20 liters per day is needed for an adult person. .
