The need of the hour is clean drinking water, and with depleting water sources, you cannot paint a rosy picture of the future. Drought conditions plague cities and alternate sources of water are the only solutions. Water Treatment perth makes use of the latest technologies and equipment to provide potable water to the citizens of Australia. Further, www.huffingtonpost.in draws your attention to the need for desalination plants in order to treat water.
Desalination Plant Requirement Before installing a desalination plant in the seabed, certain criteria must be fulfilled by the plant. It includes: · Brine water discharged from the unit must not have an adverse impact on the environment. · There must be minimum impact on aquatic life and environment during the installation of the plant. · The intake systems should not lead to seabed erosion and other effects that can come in the way of local marine life.
The DWG or Desalination Working Group lists few energy-efficient factors like: · An optimal amount of seawater must be extracted for treatment. Processing more than what is required can lead to an ecological imbalance. · Pre-treatment should include effective methods that provide clean water to the RO membranes. There should be no incidences of chemical usage, and no foul smell must emanate from the water. · Solar panels and other natural energy-efficient methods must be used in the desalination plant.
The Process In A Nutshell The intake station is located few kilometers away from the main unit, and untreated seawater flows through a narrow tunnel to reach the pumping station. Here, the seawater makes its way through band screens that help in removing large particulate matter. Partially treated water flows through disc filters that help in removing barnacle larvae. An ultrafiltration system immersed in water removes particles greater than 0.1 microns and eliminates viruses and bacteria.
Pressure Exchangers Filtered seawater is now transferred to the RO plant at varying pressure. This practice ensures a reduction in the total energy requirement by the desalination plant.
Gravitates To Storage Units The primary processing unit is located at a distance of 52m above sea level. After the exchange of pressure in the RO plant, the treated water gravitates to the storage tanks.
Recycling Water For optimal energy utilization, the disc filters and RO membranes have to be cleaned to get rid of trapped particles and solids.
Solar Powered Cells Photovoltaic systems are responsible for the generation of electricity that is used for lighting and ventilation in the buildings.
Operational Capability The desalination plant has the capacity to supply 30 million liters per day up to 300ML/day. The ease with which water is supplied to customers ensures that their daily requirement of water is met. The unique design of the plant and varying pressures at different stages ensure energy is used economically.
Sustainable principles must be practiced from the planning stage and right through design, construction and operation. This creates a minimal negative impact on the environment. The desalination project is an example of generating clean water from raw seawater, using energy-efficient methods for the use of future generations.
