Healthy Environment with Clean Wastewater Management Stages
Wastewater treatment needs to be understood because if it is not done properly it can cause environmental pollution. Water polluted by sewage will seep into the ground, causing acid.
If it flows into the river, it will kill the biota in it. If the condition is not treated immediately, it can seep into the groundwater. Even though this ground water is widely used by humans for consumption needs, of course it is very dangerous.
3 Indicators of Water Pollution
To be able to carry out wastewater treatment properly, it is first necessary to know what the pollution indicators are. There are 3 indicators of pollution that can be observed, namely chemical, physical and bacteriological.
- Chemical indicators can be seen from the chemical substances contained. These chemicals are heavy metals and other dangerous chemicals. In plain view, there is not much difference from clean water, but if it is proven to be polluted, it will be harmful to health.
- Physics indicators can be seen from the physical appearance. Such as color, odor, temperature, and turbidity level. If there are contaminants from the waste, the appearance will not be clear, it tends to be colored, for example, as a result of contamination by textile dyes.
- The third indicator of contamination is the presence of bacteriological content. This can be seen from the number of bacteria per area or a certain size. The parameter is the amount of coliform, puristic and pathogenic, whether it crosses the threshold or not.
Wastewater Treatment Methods
Waste is the product that is no longer used from household activities, industry or other public places. Because it is the result of use, it contains substances that are not supposed to be a condition of cleanliness.
That doesn’t mean it can’t be used at all, but proper wastewater treatment is needed. Namely separating or neutralizing contaminants, the result will be clean water ready for use. There are several methods that can be applied in this case.
1. Dilution
Polluted water is diluted so that it has a lower concentration before being discharged into the drains.
2. Oxidation Ponds
Waste water treatment using the oxidation pond method utilizes sunlight, oxygen, bacteria, and algae (algae). These four elements are able to clean all contaminants naturally.
3. Irrigation
The irrigation method is carried out by flowing into an open ditch, this allows seepage into the soil through the bottom and walls of the ditch. A natural filtering process occurs in this method.
Wastewater Treatment Stage
In a larger scope, such as pollution due to industrial activities, certain stages of processing are needed. The point is to ensure that the end result of processing is completely safe for the environment and humans.
1. Introduction
The first stage is preliminary, where the waste will be separated from the coarse solids with fat or oil. The facilities needed include filters, enumerators, sand catchers, grease traps, and equalization tanks.
2. The first stage
The first stage is carried out by reducing the suspended solids content. The trick is through the process of deposition of solid particles. In this stage, chemicals are used to increase neutralization ability.
3. Second Stage
The biological oxidation mechanism stage, the goal is to reduce organic matter. In this case the quantity of liquid waste, the ability to reduce organic matter, to the available land is taken into account, supported by facilities in the form of drip filters, stabilization ponds and activated sludge units.
4. Advanced Processing
Advanced processing aims to remove phosphorus and nitrogen compounds, remove residual organic matter and compounds that cause color, and remove dissolved solids in the waste.
In order for processing to be more optimal, you can entrust it to third parties, such as Sucofindo. Sucofindo provides effluent testing to determine appropriate actions in wastewater treatment.
