Methods Used in Wastewater Treatment
Water is an important substance in every home and industries. It is used daily in cleaning and cooking in our homes. Water in industries is utilized as a solvent and a coolant in various manufacturing processes. However, water supply has become scarce owing to increased utilization in homes and industries. This realization has led to recycling of used water. Some wastewater treatment Sydney processes have been set up to alleviate this shortage. This treatment clears waste water from pathogens and foreign materials making it ready for use both in homes and in industries.
Processes of wastewater treatment in Sydney
Sedimentation is a method used to clear large quantities of water containing particles and other foreign materials. The process involves moving water into large tanks. After a while, the heavy particles settle on the lower section of the tanks. Clearwater from the top part is siphoned off. This method clears dense particles while filtration clears smaller and less dense particles.
Water containing small particles is harmful to our health. Also, the use of such water can lead to machinery failure and pipes to clog in industries. Removal of small particles in water is by passing it through several filters. These filters, arranged in decreasing mesh sizes ensure elimination of the smallest particles. Alternatively, the wastewater treatment Sydney has today utilizes a sand bed that retains these particles as water passes through the bed.
Filtration using filters does not clear minute particles to ensure safety in the water. Good but cheap wastewater treatment Sydney has now utilizes filter membranes. These membranes have the capacity to remove particles with sizes less than 0.2 micrometers. Also, ultra filtration removes certain microbes like Giardia and Cryptosporidium.
Boiling is the oldest and most traditional method of water treatment. Boiling involves heating water at a temperature of 100 degrees Celsius. This heat destroys all disease causing pathogens to humans. Most Sydney wastewater treatment institutions advise people to boil drinking water from sources that have not been certified. These sources include rainfall and water supplied by various companies.
Treatment with chemicals
Chlorine is used for treating water as sodium hypochlorite. This form of chlorine ensures rapid destruction of microorganisms present in water. Companies involved in wastewater treatment Sydney has today apply this chemical to storage water with calculations on the quantity required for certain amounts of water. Excessive amounts of chlorine are toxic for human consumption. Therefore, it is important to exercise caution while using this component.
Softening hard water
Hard water contains large quantities of calcium and magnesium carbonates. Hard water presents a problem in homes when washing with soap. This water is difficult to lather resulting to a requirement of a greater amount of detergents. Besides, hard water contains chemicals that react with supply pipes and industrial machinery. Water hardness has been eliminated by wastewater treatment Sydney companies by use of ion exchange resins. Sodium or potassium ions dissolved in hard water replaces the calcium ions. This reaction results in soft water that eliminates the problems of hard water.
