What are the dimensions of a water treatment plant?
A water treatment plant is designed for 30 million gallons per day (mgd). The flocculator dimensions are length = 100 ft, width = 50 ft, depth = 16 ft. Revolving paddles attached to four horizontal shafts rotate at 1.7 rpm. Each shaft supports four paddles that are 6 in. wide and 48 in. long. Paddles are centered 6 ft from the shaft.
When was the first potable water treatment plant launched?
Already in 2001, the first potable water treatment plant using a MIEX®-DOC process was launched in Australia. In this plant, the MIEX®-DOC step was introduced prior to conventional treatment, and a significant improvement in water quality was observed.
What is automation of water treatment plant?
Automation of water treatment plant involves the control system opening and closing valves and starting and stopping equipment in predefined sequences to complete specific tasks or to provide the desired process plant output. From:Water Supply (Sixth Edition), 2009
How are water treatment plants construction?
The construction of wastewater treatment plants involves the use of a large amount of metal, concrete and other materials. In addition, the preparation of the construction site produces large volumes of soil, sand and stone after digging channels.
How long does the water treatment process take?
How long does it take to treat the wastewater? Approximately 24 hours.
How many stages are there in water treatment plant?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment.
What are the 6 stages of water treatment?
They typically consist of several steps in the treatment process. These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.
What are the 5 stages of water treatment?
Public water systems often use a series of water treatment steps that include coagulation, flocculation, sedimentation, filtration, and disinfection.
What are the 4 steps of water treatment?
4 Steps of Community Water TreatmentCoagulation and Flocculation. ... Sedimentation. ... Filtration. ... Disinfection.
What is the last stage of water treatment?
Tertiary treatmentTertiary treatment, also known as polishing, disinfects water to the highest standards. This stage is necessary to produce water to specification, such as technical waters, and to treat wastewater for public water systems. UV disinfection requires no chemicals, and it can be used in place of chemicals.
What are the 7 methods of water treatment?

The project was completed on a tight schedule, on a small site without disruption of an active refinery, despite record wet weather.
What is water treatment?
Water treatment is the process of removing all those substances, whether biological, chemical, or physical, that are potentially harmful to the water supply for human and domestic use. This treatment helps to produce water that is safe, palatable, clear, colorless, and odorless. Water also needs to be non-corrosive, meaning it will not cause damage to pipework.
How does aerated water work?
After screening, the water is aerated (supplied with air) by passing it over a series of steps to take in oxygen from the air. This process helps in expelling soluble gases such as carbon dioxide and hydrogen sulfide (both of which are acidic, so this process makes the water less corrosive) and expels any gas eous organic compounds an undesirable taste to the water. Aeration also removes iron or manganese by oxidation of these substances to their insoluble form. Iron and manganese can cause peculiar tastes and can stain clothing. Once in their insoluble forms, these substances can be removed by filtration.
What is the process of separating solids from liquids?
Filtration is the process where solids are separated from a liquid. In water treatment, the solids that are not separated in the sedimentation tank are removed by passing the water through sand and gravel beds. With a flow rate of 4–8 cubic meters per square meter of filter surface per hour, rapid gravity filters are often used.
What happens after aeration?
After aeration, coagulation occurs to remove the fine particles (less than 1 µm in size) suspended in the water . In this process, a chemical called a coagulant (with a positive electrical charge) is added to the water, which neutralizes the fine particles' negative electrical charge. The coagulant's addition takes place in a rapid mix tank where a high-speed impeller rapidly disperses the coagulant.
