Stages of Waste Water Treatment Process.
There is release of variety of waste from both domestic and industrial such as water, solids and gases. These wastes are absorbed into the environment and can be dangerous. However, if the wastes are taken through treatment plants, the amount of harm done to the environment could be minimal. 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. A typical waste product in both homes and industries is the wastewater. The wastewater treatment process involves various stages.
Wastewater from homes is normally treated in septic systems. The septic system is simple and should always be functional. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume 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 that can help you design and manufacture a treatment plant. A project plan is made according to the unique circumstances surrounding it. Engineers at the manufacturers will oversee the project from its design stage to monitoring and maintenance works. These types of plants are huge capital investments and are also sophisticated. 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. In these reservoirs, there is removal of floating and suspending solids. The process involves use of centrifugal force. The stage removes about 60% of the suspended solids. 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. More than 80% of impurities in the water are removed at this stage. The water that is released into the environment at this stage is not harmful.
The third stage is however introduced to make the water pure. This phase is known as tertiary level, and the water released here can be used for different purposes. Various chemicals are applied to remove the impurities and ensure that it is safe. Chlorine is used to purify the water though it has been disputed in the recent times.
When water is being pumped into the treatment plant; it 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.
