The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants ...
What is the treatment for drinking water?
Treatment for drinking water production involves the removal of contaminants and/or inactivation of any potentially harmful microbes from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. In general terms, the greatest microbial risks are associated with ingestion of water that is contaminated with human or animal (including bird) faeces. Faeces can be a source of pathogenic bacteria, viruses, protozoa and helminths. The removal or destruction of microbial pathogens is essential, and commonly involves the use of reactive chemical agents such as suspended solids, to remove bacteria, algae, viruses, fungi, and minerals including iron and manganese. Research including Professor Linda Lawton 's group at Robert Gordon University, Aberdeen is working to improve detection of cyanobacteria. These substances continue to cause great harm to several less developed countries who do not have access to effective water purification systems.
Why is water treatment important?
This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
How is saline water treated?
Saline water can be treated to yield fresh water. Two main processes are used, reverse osmosis or distillation. Both methods require more energy than water treatment of local surface waters, and are usually only used in coastal areas or where water such as groundwater has high salinity.

Packed tower aeration (PTA) uses towers filled with a packing media designed to mechanically increase the area of water exposed to non-contaminated air. Water falls from the top of the tower through the packing media while a blower forces air upwards through the tower.
What is the process of a bioreactor?
The process has a vessel or basin called a bioreactor that contains the bacteria in a media bed. As contaminated water flows through the bed, the bacteria, in combination with an electron donor and nutrients, react with contaminants to produce biomass and other non-toxic by-products.

GACs are manufactured from a variety of raw materials with porous structures including: Physical and/or chemical manufacturing processes are applied to these raw materials to create and/or enlarge pores.
What is the process of cation exchange?
In a cation exchange treatment process, water passes through a bed of synthetic resin. Positively charged contaminants in the water are exchanged with more innocuous positively charged ions, typically sodium, on the resin’s surface.
Why is water treatment important in power plants?
In power plants such as coal-fired, nuclear, co-generation and gas-steam, water treatment is a key element to ensure the efficiency of the water cooling system. The efficiency of the operation also contributes to guaranteeing its ecologically positive contribution, while being economically viable.
What are the threats to water?

Water purification, conservation and wastewater treatment are processes currently implemented in order to ensure an adequate and optimised use of water.
What is bromine in water?
Bromine-based products are ideal solutions for water treatment applications thanks to bromine’s ability to kill harmful contaminants 1 by combining with bacteria and other living organisms in water. Bromine dissociates in water by forming hypobromous acid (HBrO) which has powerful disinfectant properties, due to its ability to kill the cells of many pathogens. Bromine is effective against tough waterborne viruses, such as poliovirus, and rotaviruses as well as a wide spectrum of bacteria 2. It also reacts with other substances in water to form bromine-containing substances. As an example, bromine reacts with ammonia compounds to form bromamines, which are very effective antimicrobials.
What is brominated compound?
Brominated compounds improve the rate at which one can recycle industrial water, the quality of industrial water discharge and the safety of recreational water facilities.

What is reverse osmosis?
Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.
What is the process of filtration?
Filtration is a physical process that occurs when liquids, gases, dissolved or suspended matter adhere to the surface of, or in the pores of, an absorbent medium. Filtration of contaminants depends highly on the amount of contaminant, size of the contaminant particle, and the charge of the contaminant particle.
How does distillation work?
Distillation Systems use a process of heating water to the boiling point and then collecting the water vapor as it condenses, leaving many of the contaminants behind. Distillation Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);
How is treated raw water treated?
Treated raw water is mixed with potable water and pumped to the boiler feedwater treatment system. The system is designed to remove 99% of the dissolved minerals and provide high-purity water to the boiler. The mixed water flows through a reverse osmosis plant operating at a recovery of 80% and an average salt rejection of 95%. Permeate from the RO mixes with product water from both the waste RO unit and the distillate from the brine evaporator/crystalliser situated in the wastewater treatment plant. The combined flow then enters a degasifier, to remove carbon dioxide, and a mixed bed dimineraliser. The mixed bed plant consists of two 100% capacity ion exchange vessels which remove the final 5% of the dissolved salts. The ion exchange beds process 2 200 000 gallons (8327 m3) before being regenerated. Waste from the process is pH adjusted and combined with the RO reject before being pumped to the wastewater treatment plant.
What is centralized water treatment?
Centralized water treatment plants are based on coagulation, flocculation and disinfection processes and found to be most cost-effective in treating large quantities of water.
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.
What is water treatment automation?
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. To achieve these results the automation system relies on signals from correctly selected and placed instruments, devices such as actuators and motor control circuits and reliable control logic. The degree of automation to be used is fundamental to developing an automation system.
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
