Malaysians consume 230 liters of water a day. In addition, the daily water use per capita in Malaysia is surprisingly high, about 6 liters per year (Kerri, 2008). Water plays an important role for human beings as a natural resource for drinking and irrigation. The increase in population and the increase in economic activity and industrial activity brought high demand for water. In order to produce drinking water, the water treatment process must be carried out appropriately.
The water treatment process has brought many importance to today's society. One of the importance of the water treatment process is to make sure that water is suitable for industrial and personal use. The purpose of the water treatment process is to remove pollutants from the water and make it more suitable for use. There are several methods for treating water such as filtration, mainly to disinfect clean water. Water is no longer a choice at all, so water is the key to human survival. Therefore it is important to make sure that it is purified to drink water. According to a global survey, many people die of aquatic life in most developing countries in the early stages. Therefore, it is very important to perform appropriate water treatment for a healthy life.
General treatment methods for water recovery There are several treatment options that you can choose at each stage of the process. Water administrators can choose one or more of these options and create a process to process the water to the quality required for the intended use. Water treatment begins with pretreatment and primary treatment for suspended particulate matter, followed by secondary treatment to remove biodegradable organic carbon. Water managers can also choose to remove nutrients and perform advanced treatments to remove organic chemicals and suspended solids. The artificial natural process makes it possible to mix the reclaimed water with water from other sources and to provide additional natural treatment to further remove contaminants from the water.
The process of recycling water. Since there are various processing techniques to achieve substantially the same results, the utility typically describes the various stages of processing, not the technique used when referring to water quality. In general, the four central stages of treatment are initial treatment, primary treatment, secondary treatment, and tertiary or advanced treatment. The main purpose of traditional wastewater treatment (ie the four phases above) is to reduce the nutrient burden on the environment and thereby maintain the health of aquatic ecosystems. For circulating water applications, conventional wastewater treatment complements additional processes to achieve consistent quality for the intended application. Regenerated water will undergo at least some form of disinfection (WateReuse Association, 2011b).
