To treat wastewater, there are several steps that must be done. Check out the short review below.
At this initial stage, the wastewater will be separated from the crude solids and fat or oil. The facilities needed for this include filters, choppers, sand traps, fat and oil catchers, and equalization tanks.
First Stage Processing
The first stage of waste water treatment plant Indonesia is to reduce the suspended solids content. The trick is through the deposition process. Solid particles will be allowed to settle. To increase the ability of neutralization or reduction of suspended solids, chemicals can be used.
Second Stage Processing
Next, you can carry out the second stage of processing, namely the biological oxidation mechanism. The goal is to reduce organic substances. To do this, it is necessary to consider the quantity of liquid waste, the ability to reduce organic matter, and the available land. The units used for this purpose are drip filter, stabilization pond, and activated sludge unit.
After that, there is also further processing that aims to remove certain contaminants. Further treatment is also useful if the waste is to be reused.
In this third stage, the treatment aims to remove phosphorus and nitrogen compounds, remove residual organic matter and color-causing compounds, and remove dissolved solids in the waste. The method used varies depending on the needs.
This processing can be done simultaneously or a combination of several stages. This can be adjusted to the needs and financial capabilities.
However, regardless of how the processing is carried out, there are standards that must be met according to the applicable regulations. The person responsible for wastewater treatment must also have a certification that demonstrates his competence.
Certification can be obtained after conducting special training. To take part in the training, you can take advantage of the services of the Quality Institute, an institution that provides various training and certifications, including those who want to be in charge of Water Pollution Control (PPPA).
