16, 2009 issued by ministry of natural resource and environment national technical regulation on industrial wastewater1. general provisions1.1. scope of regulation this regulation provides for maximum allowable values of pollution parameters in industrial wastewater discharged into receiving facilities1.2. subjects of application 1.2.1. this regulation applies to individuals and organizations carrying out activities related to the discharge of industrial wastewater in to receiving facilities 1.2.2. wastewater of some industries and field of particular activities shall be regulated separately 1.3. interpretation of termsin this regulation, the terms below are construed as follows1.3.1. industrial wastewater means solution discharged from industrial manufacturing, processing, trading and servicing premises into wastewater-receiving facilities 1.3.2. kq means discharge coefficient/volumetric capacity of the receiving facilities corresponding to flow discharge of river, stream, spring, canal, channel, streamlet, rillet and volumetric capacity of reservoir, lake, pond and swamp 1.3.3. kf discharge coefficient of wastewater-discharging sources of industrial manufacturing, processing, trading and servicing premises into wastewater-receiving facilities1.3.4. wastewater-receiving facilities means surface water bodies or coastal water areas used with particular and specific purpose where industrial wastewater is discharged into1. technical regulation2.1. the allowable maximum value of pollution parameters in industrial wastewater is calculated as follows:cmax = c x kq x kf where:- cmax is allowable maximum value of the pollution parameter in industrial wastewater discharged into receiving facilities, measured in milligram per liter (mg/l);- c is value of pollution parameter in industrial wastewater stipulated at section 2.3- kq is discharge coefficient/volumetric capacity of the receiving facilities stipulated at section 2.4- kf is discharge coefficient of wastewater source stipulated at section 2.52.2. cmax = c (without coefficient of kq and kf) is applied to parameters: temperature, ph, odour, colour, coliform, gross activity and gross activity 2.3. the c value of pollution parameters in industrial wastewater is stipulated at the table no. 1 below:table 1: the c value of pollution parameters in industrial wastewatero.

stipulates value c of pollution parameter in industrial wastewater discharged into receiving facilities using for sources of domestic water supply- colume b stipulats value c of pollution parameter in industrial wastewater discharged into receiving facilities not using for sources of domestic water supply- parameter of chlorine shall not be applied to receiving facilities which are brackish and salt water2.4. discharge coefficient/volumetric capacity of receiving facilities kq is stipluated as follows2.4.1. coefficient kq corresponding to flow discharge of receiving facilities whichs are river, stream, spring, canal, channel, streamlet, rillet is stipulated at the table no. 2 below:table 2: coefficient kq of receiving facilities whichs are river, stream, spring, canal, channel,

discharge of river, stream, spring, canal, channel, streamlet, rillet during 03 driest months of 03 successive years (data issued by meteorological-hydrological agency). if there is no data on flow discharge of river, stream, spring, canal, channel, streamlet, rillet the value kq=0,9 shall be applied or department of natural resource and environment managing areas where wastewater-discharging sources are located shall appoint a unit with appropriate function to define average discharge during 03 driest of year for the basis of selecting coefficient kq2.4.2. coefficient kq corresponding to
