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. The harm made to the environment can, however, be reduced by taking waste through treatment plants. 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. The wastewater treatment process is carried out in three phases.
Wastewater from homes is normally treated in septic systems. 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. There are however waste water treatment plants for use in large residential estates and factories. There are manufacturers of wastewater treatment plants and can assist you in design and construction of wastewater treatment plants. 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 are a sophisticated process that requires large investments. These systems remove quality clean water and thus used at commercial levels.
The water treatment process ahs three main phases. Water flows to reservoirs either by pumping or gravitational force. There is removal of floating and suspending solids in the reservoirs. Centrifugal force is applied at this stage. 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. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. These organisms consume the biodegradable components in the water and remove the nutrients such as phosphorus and nitrogen present. This stage removes over 80% f the water impurities. The water that is released into the environment at this stage is not harmful.
However, to make the water pure, the third stage is incorporated. The phase is referred as the tertiary level and the water released is usable for a variety of uses. There is application of different water treatment chemicals to make it safe. Some firms use chlorine to remove all impurities though it has become a subject of discussion in the recent.
When water is being pumped into the treatment plant; it 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.
