Stages of Waste Water Treatment Process.
Both domestic and industrial processes leads to variety of waste including solids, water and gases. These types of wastes are directed into the environment and cab e hazardous. However, taking these wastes through treatment process reduces harm made to the environment. The waste treatment process produces harmless products such as water, recycled products and harmless, biodegradable products. The processes involved in the treatment of these wastes differs depending on the source and the type of waste. Wastewater is common in most process including in homes and industries. The wastewater treatment process is carried out in three phases.
The septic system is used to treat water in most homes. The septic system is not complicated but should always be functional mode. Nevertheless, septic systems that serve several homes are more complex since they have to absorb lots of waste. Large water treatment plants for use in large factories and high residential areas are however available. There are manufacturers of wastewater treatment plants and can assist you in design and construction of wastewater treatment plants. They will design the plan according to the project specific needs. They have engineers who will oversee the whole project from the design stage to the monitoring and maintenance tasks. These types of plants are huge capital investments and are also sophisticated. These systems remove quality clean water and thus used at commercial levels.
The wastewater treatment plants involve three main stages. water flows through pipes by means of pumping or gravitational force. In these reservoirs, there is removal of floating and suspending solids. This process happens in the presence of centrifugal force. About 60% of solids will be removed at this stage. Removal of solids can be increased through addition of chemicals. The water is taken to the second stage of treatment known as the secondary stage of organic stage. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. These organisms consume the biodegradable components in the water and remove the nutrients such as phosphorus and nitrogen present. About 80% of water impurities is removed at this stage. Water passed through his phase is not hazardous to the environment.
water is however made pure by
taking it to the third stage. It is referred to as the tertiary stage and water can be used for a wide range of uses. Various chemicals are applied to remove the impurities and ensure that it is safe. Some firms use chlorine to remove all impurities though it has become a subject of discussion in the recent.
Water pumped to the treatment plant should not contain industrial chemicals. The company that is producing water containing chemicals should remove these chemicals by having a treatment plant at their base.
