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, 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. A typical waste product in both homes and industries is the wastewater. The wastewater treatment process is carried out in three phases.
The septic system is used to treat water in most homes. 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 waste water treatment plants for use in large residential estates and factories. 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. 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.
There are three main stages in the water treatment process. 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. Removal of solids can be increased through addition of chemicals. water is then pumped to the secondary stage which is referred to as the organic stage. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. The organism in the water eat the food particles in the water remove the phosphate and nitrates nutrients 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. 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.
Water pumped to the treatment plant should not contain industrial chemicals. The company responsible for releasing water with industrial chemical should take responsibility by establishing a treatment plant at their base to remove the chemicals.
