Stages of Waste Water Treatment Process.
Industrial and domestic processes lead to various forms of waste including water, solids and gases. These wastes are absorbed into the environment and can be dangerous. However, taking these wastes through treatment process reduces harm made to the environment. The end products from the waste treatments plants include recycled products, clean water and safe, biodegradable products. The processes involved in the treatment of these wastes differs depending on the source and the type of waste. Wastewater is a produced in typical all process including homes and industries. There are different stages of the wastewater treatment process.
Most homes treat their water using the septic system Though the septic system is simple, it should always remain functional. However, septic systems serving large populations are complex since they have to absorb lots of waste. There are however wastewater treatment plants for use in high factories and residential estates. There are manufacturers of wastewater treatment plants and can assist you in design and construction of wastewater treatment plants. The process needs to be carried out per the circumstances. The manufacturers have engineers who handle the project since its inception to monitoring and maintenance works. These are a sophisticated process that requires large investments. The water released from these systems are quality clean and therefore used at commercial levels.
The wastewater treatment plants involve three main stages. water flows through pipes by means of pumping or gravitational force. There is removal of floating and suspending solids in the reservoirs. Centrifugal force is applied at this stage. 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. The organism in the water eat the food particles in the water remove the phosphate and nitrates nutrients in the water. About 80% of water impurities is removed at this stage. Water passed through his phase is not hazardous to the environment.
The third stage is however introduced to make the water pure. It is referred to as the tertiary stage and water can be used for a wide range of uses. The water may be treated using various chemicals to ensure its safety. Chlorine is used by several firms though it have become a subject of debate in the recent.
Water pumped to the treatment plant should not contain industrial chemicals. The individual factory releasing such waters should take individual responsibility by establishing a treatment plant at their base before releasing such water.
