Cmax is the maximum permissible concentration of pollutants in the emission discharged to the environment by the producing and trading establishments, expressed in milligram per cubic meter of emission in standard condition (mg/Nm3);
C is the value of the maximum permissible concentration of pollutants in TCVN 5939:2005;
Kp is the coefficient of wastewater flow rate;
Kv is the coefficient of the region where the establishments are situated.

The values of Kp are provided in Table 1A below.
Table 1A: Values of Kp corresponding to the flow rate of wastewater discharged by the producing and trading establishments.
Wastewater flow rate; Unit: cubic meter per hour (m3/h) | Giá trị hệ số Kp |
