Water Treatment – Phosphorous Removal Phosphorus and nitrogen are nutrients that are essential for aquatic plant and algae growth. However, an over-abundance of these nutrients can over-stimulate plant and algae growth such that they create water quality problems. The discharges of treated wastewater can be the most significant source of phosphorus loading and state environmental…
Water Treatment – Disinfection The overriding objective of water treatment is the removal or inactivation of pathogenic micro-organisms to prevent the spread of waterborne disease. It is important that water treatment works be equipped with adequate disinfection systems, when pristine water supplies collected from catchments totally under the control of the water supply authority are…
Municipal Wastewater Treatment Systems For the first half of the 20th century, pollution in the Nation’s urban waterways resulted in frequent occurrences of low dissolved oxygen, fish kills, algal blooms and bacterial contamination. Early efforts in water pollution control prevented human waste from reaching water supplies or reduced floating debris that obstructed shipping. Water pollution…
