Stages of Waste Water Treatment Process.
Both domestic and industrial processes leads to variety of waste including solids, water 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. Wastewater is a produced in typical all process including homes and industries. The wastewater treatment process is carried out in three phases.
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 assist you in design and construction of wastewater treatment plants. The process needs to be carried out per the circumstances. 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 water treatment process ahs three main phases. Water flows through pipes either by pumping or gravitational force to large reservoirs. In these reservoirs, there is removal of floating and suspending solids. This process happens in the presence of centrifugal force. The stage removes about 60% of the suspended solids. Chemicals can be used at times to increase the removal of solids. water is then pumped to the secondary stage which is referred to as the organic stage. In this phase, the remaining biodegradable particles are provided as food to controlled 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 released to 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. Chlorine is used by several firms though it have become a subject of debate in the recent.
Water pumped into the wastewater 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.
