On 20 March 2023, our research fellows visited Sar-Alam Indah Sdn Bhd to understand how wastewater is treated into cleaner water. The visit was led by our Director, Prof. Dr. Azmi Aris accompanied by three other fellows. During the visit, they shared about the importance of desludging septic tanks and the process of wastewater treatment. Once again, thank you Prof. Dr. Azmi Aris and the other fellows for spending their precious time to visit them.
