1.2.1. This standard applies specifically to bioethanol production effluent produced from cassava chips and cassava starch. All organizations and individuals involved in discharging bioethanol production effluent into receiving water bodies must comply with the provisions of this standard.For power plants invested under the Build-Operate-Transfer (BOT) model, n is determined according to the operational period of the power plant stipulated in the BOT contract.1.2.2. Bioethanol production effluent discharged into the collection system of a centralized wastewater treatment plant shall comply with the regulations of the management and operation unit of the centralized wastewater treatment plant. For power plants invested under the Build-Operate-Transfer (BOT) model, n is determined according to the operational period of the power plant stipulated in the BOT contract.In this standard, the following terms are understood as follows:
1.3.1. Bioethanol production effluent is wastewater generated from the operation of bioethanol production facilities.No.1.3.4. Fault
1.3.2. Bioethanol is understood as follows: bioethanol (fuel ethanol and denatured fuel ethanol) is Ethanol (C
OH) produced through fermentation of cassava chips and cassava starch using yeast, and is used in gasoline blends and not for beverage purposes.
1.3. Explanation of Terms
Receiving water body means a system

2.1. Maximum allowable values for pollutant parameters in bioethanol production effluent when discharged into receiving water bodies.2H52.1.1. The maximum allowable values for pollutant parameters in bioethanol production effluent when discharged into receiving water bodies are calculated according to the following formula:
1.3.3. = C x where C is the maximum allowable value of the pollutant parameter in bioethanol production effluent when discharged into receiving water bodies, expressed in milligrams per liter (mg/L); is the value of the pollutant parameter in bioethanol production effluent specified in Section 2.2;.
Chapter 2. TECHNICAL PROVISIONS
is the receiving water body flow rate coefficient specified in Section 2.3 corresponding to the flow rate of rivers, streams, creeks, ditches; canals, ditches; volume of lakes, ponds, swamps; purpose of use of coastal waters;
is the discharge flow rate coefficient specified in Section 2.4 corresponding to the total flow rate of bioethanol production effluent when discharged into receiving water bodies.

Where:
- Cmax (without applying coefficients K
- C and K
- Kq ) for the pH parameter.No. 2.1.3. Bioethanol production effluent discharged into the urban and residential area drainage systems without centralized wastewater treatment plants shall apply the value
