The installation of a carbon adsorption unit will be All Primary and Carbon Adsorption Technically Feasible evaluated should additional measures be needed Secondary Sources to control odours. Carbon adsorption would only be useful for smaller, unsaturated flows. Ozonation is an emerging technology and there is All Primary and Ozonation Technically Not limited documentation on demonstrated control Secondary Sources Feasible efficiency or applicability on VOC and odour destruction. NTP is an emerging technology and there is limited All Primary and Non-Thermal Plasma (NTP) Technically Not documentation on demonstrated control efficiency Secondary Sources Feasible or applicability on VOC and odour destruction. It is also not suitable for exhaust gases with high moisture content. The DAF system has been optimized, and DAF Process Optimization: Technically Feasible – monitoring is conducted to identify changes in previously implemented Optimize Bubble Size operating parameters that may require adjustments to maintain bubble size. The flocculation and coagulation chemical addition DAF Process Optimization: Technically Feasible – to the DAF system has been optimized and is previously implemented Optimize Flocculation/Coagulation automated. Chemistry The facility would conduct a review of the Rotary Screen BREF BAT Specific to Technically Feasible processes to identify opportunities to remove heat Wastewater Treatment: and thereby reduce the temperature of the Temperature wastewater requiring treatment.
