(Peer review+Similarity+Dokumen) Pilot Plant of Water Treatment Unit for Flood Water becomes Clean Water with Pneumatic Flash Mix

Water is primary needs for human beings in any condition such as in disaster condition. More specifically in floods where water condition is abundant but cannot be consumed because it does not comply the existing quality standards. This pilot plant is based on the condition where the location of flood is quite difficult to be accessed and the energy resources are limited. In principle, this water treatmen unit in the future is only intended to treat flood water. The process that occurs in this reactor was the coagulation and flocculation process which were done by batch system Flash mix process using a pneumatic system and slow mix process using pedals were applied in this reactor. All process was done without involving the electrical energy, this was due to limited access to disaster conditions. At this stage, this pilot plant was proved to be effective for decreasing TDS and turbidity in flood water. The turbidity parameter showed the quality of raw water was 14.5 NTU and the treated water turbidity value was 6.51 NTU. Thus, the percentage of removal for turbidity parameter was 55,1%. The decline of turbidity affects the decrease of TDS value. The value of TDS in raw water was 135 mg/l while in the treated water was 1.27 mg/l. As a result, the percentage of TDS removal was 99.06%.
