What is the Bendigo water treatment plant?
I. Bendigo water treatment plant (BWTP). The 12.54 × 10 4 m 3/day (33 MGD) BWTP has been producing drinking water for nearly 1 million people in central Victoria, Australia since 2002. It is one of the largest if not the largest MF plant in the world. The plant combines submerged microfiltration (CMF-S), ozonation and biological activated carbon (BAC) to treat a variable and difficult raw water. Raw (surface) water is pre-screened, and dosed with lime and carbon dioxide in a contact reactor to control alkalinity and corrosion. Next, water is dosed with a coagulant, liquid aluminium chlorohydrate (ACH) prior to entering the CMF-S plant to remove colour, some organic content, and dissolved metals. The coagulant dosage is typically 5–6 mg/l. The coagulant precipitate is removed by MF. The coagulant/CMF-S process removes up to 15% of the dissolved organic carbon.64

What is raw water pretreatment?
The raw water pretreatment plant is designed principally for solids removal from the incoming Hanover county sewage effluent (grey water), backwash water and wastewater from the oily water collection system. Raw water enters a coagulation/flocculation chamber followed by a clarifier and dual media depth filters. Backwash water from the filters is periodically returned to the clarifier. Clarifier sludge is dosed with polymer before being thickened and then sent to the filter press for dewatering. The cake is sent to landfill and the recovered water returned to the clarifier.

How is potable water run?
Potable water is run backwards through the filters releasing the entrapped particulates that are collected in drain troughs. The backwash water is sent to the Backwash Recovery Pond and, after a settling process, the backwash water is returned to the raw water settling pond for re-use.
What is the first chemical added to water?
The first chemical added is chlorine dioxide and it is an oxidant used to break down naturally occurring organic matter such as decaying leaves and other plant material. A chemical coagulant known as aluminum sulfate is used as the primary coagulant. A polymer, a long chain of synthetic organic compounds, is also added to the water as a coagulant aid to help in strengthening the primary coagulant’s bonding chains. The coagulants are added at the rapid mix unit; this is a unit that creates turbulent mixing energies to help thoroughly disperse the chemical coagulants into the raw water and to begin the coagulation process. The coagulants that cause very fine particles to clump together into larger particles that can then be removed later in the treatment process by settling, skimming, draining or filtering.

Distillation is a process in which impure water is boiled and the steam is collected and condensed in a separate container, leaving many of the solid contaminants behind. Disinfection. Disinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed.
Why is surface water more contaminated than ground water?
Typically, surface water requires more treatment and filtration than ground water because lakes, rivers, and streams contain more sediment and pollutants and are more likely to be contaminated than ground water. Some water supplies may also contain disinfections by-products, inorganic chemicals, organic chemicals, and radionuclides.
What is a water softener?

What are the resources used in water treatment?
The local water treatment plants usually rely on natural resources for procuring water, however; that is not always the case. The resources include river, dam, and well. The water that is obtained from these sources is treated thus making it safe for humans to consume at a mass level.
What are the three methods of disinfecting water?
Once the filtration is over, the water is disinfected. There are three approaches that can be employed; chlorination, ozone treatment, and ultraviolet treatment . These approaches can be used either individually or in combination. Once all of these steps are completed, water is pumped out to be used by the population.
What is the process of removing particles from water?
The process is not simple and begins with coagulation and flocculation. This particular process is responsible for removing all of the natural particles that accompany water from the actual water source. Coagulants, when added to the water, can make the debris stick together. An example of a typical coagulant is aluminum sulfites ...
How are coagulants introduced into water?
These coagulants are introduced in the water when it enters the treatment plant. The water is then passed through flocculation basins where slow mixing takes place. This mixing makes sure that thorough coagulation takes place. Once coagulation is completed, the water is pumped into a sedimentation basin. Water is allowed to sit thus enabling the ...
Why are water treatment plants important?
Water treatment plants are critical for a municipality so that clean water can be supplied to the local community. The process of water purification in water plants requires specialists to ensure safe and effective operation. The whole procedure occurs in stages and involves a combination of technical processes.
What chemicals are used in water treatment plants?
Polyelectrolyte, ferrous sulfate, and aluminum sulfate are examples of chemicals used in the water treatment plant process to aid coagulation. Adding these coagulating agents during these water treatment plant steps requires careful administration by qualified engineers, as measurements of the chemicals need to be precise.
What is the process of coagulation of water?
These mix the chemicals and water together and enable the micro particles to form into larger pieces that are likely to stick together, making the sedimentation process in water treatment more effective. This process is known as flocculation.
What is added to water after it is clarified?
Once clarified water leaves the sedimentation basins in the treatment plant, chlorine is added during the disinfection water treatment stage. After the chlorine wastewater treatment occurs, ammonia follows which forms chloramine. This chloramine disinfected water passes through a further set of basins to complete the disinfection process.
What is the pH adjustment in water?
pH Adjustment. After the disinfection phase the water undergoes a pH treatment stage. Lime or calcium oxide makes water less acidic by adjusting the pH. It is also less corrosive to domestic water pipes. Polyphosphate solution is also added to the water at this stage to keep the lime dissolved.
What is the first step in water treatment?
Coagulation. When water enters a treatment plant, the first stage in the process is coagulation where chemicals are added to the water supply to enable microparticles and small solids to stick together. Polyelectrolyte, ferrous sulfate, and aluminum sulfate are examples of chemicals used in the water treatment plant process to aid coagulation.
