Stages of Waste Water Treatment Process.
Both domestic and industrial processes leads to variety of waste including solids, water and gases. The wastes are absorbed into the environment and cab harmful, 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 choice of treatment plant is dependent on the source and type of waste. A typical waste product in both homes and industries is the wastewater. There are different stages of the wastewater treatment process.
The septic system is used to treat water in most homes. 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 and can help with the design and construction of wastewater treatment plant. A project plan is made according to the unique circumstances surrounding it. They have engineers who will oversee the whole project from the design stage to the monitoring and maintenance tasks. These systems are complex and require large capital outlay. These systems remove quality clean water and thus used at commercial levels.
The water treatment process ahs three main phases. water flows through pipes by means of pumping or gravitational force. In these reservoirs, there is removal of floating and suspending solids. Centrifugal force is applied at this stage. About 60% of solids will be removed at this stage. Chemicals can be used at times to increase the removal of solids. The water is taken to the second stage of treatment known as the secondary stage of organic stage. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates in the water. More than 80% of impurities in the water are 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. Various chemicals are applied to remove the impurities and ensure that it is safe. 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 company that is producing water containing chemicals should remove these chemicals by having a treatment plant at their base.
