Production Waste Water Management

Post Date 02/04/2019

Where Is The Waste Water Left Over From The Production Process Produced By PT Gistex? Is It Thrown Into The River? Of Course Not !

The process of discharging the remaining waste from the production process will pass through several processes of the existing Waste Water Treatment Plant (WWTP) of PT Gistex Textile Division using a biological treatment system so that the discharged water is still within normal limits. The scheme of the waste treatment process includes the following:
1. Chopsticks
    Waste from the production process is accommodated in chopsticks with the intention to eliminate fluctuations in the
incoming waste discharge.
2. Neutralization
    Chemicals are included to help neutralize the pH of waste water in the Neutralization bath.
3. Equalization
    After that the waste water is put into an equalization bath to even the character of the wastewater after being neutralized in
the neutralization bath.
4. DAF (Dissolved Air Flotation) 1
    Furthermore, the waste water is inserted into the DAF (Dissolved Air Flotation) Tub 1, where flotation / flooding occurs in the
waste water so that solid particles
    separated from waste water.
5. Decoloring
    The process of decomposition and color breakdown in wastewater involving anoxic activated sludge (requires limited oxygen
supply). This tub is equipped with
   diffuser that can be adjusted bubble strength to supply oxygen needs are limited.
6. Aeration
   Biological wastewater decomposition process involving suspension of activated aeration mud (complete mix). The processing
takes place aerobically (a process that requires oxygen) by utilizing the activity of microorganisms to reduce biodegradable
organic material into suspended material. This tub equipped with surface aerators to supply oxygen.
7. Clarifier
   The process of splitting water with mud takes place.
8. DAF (Dissolved Air Flotation) 2
   Addition / inject of chemicals in water and flotation / floatation of impurities in wastewater so that solid particles are
separated from waste water.
9. Effluent
   The temporary storage of waste water is then channeled to the receiving water body, namely the Citarum river.
