1. Proj. Name：Waste Water PP Fiber Filtering Equipment (Incl. Installation,

Commissioning & Training, etc.)

2. Client：CPC Refining Business Div. Tao-yuan Refinery 

3. Proj. Period：Feb. 2018∼Jan. 2019

4. Proj. Description：

Wastewater will be transferred from the existing monitoring pond of wastewater treatment unit Tao-yuan Refinery to the PP fiber filtering equipment by newly mounted submersible pumps for filtration. The suspended solid (SS) shall be ≦10 mg/L or >80% relative removal rate to comply with the treated wastewater quality standard with the total throughput of 10,000CMD. The filtered effluent will be derived through pipe to new filtered water storage tank. Then drain by gravity flow into the existing discharge pond. A provision nozzle shall be mounted at the bottom of filtered water storage tank for future connection and recycle use. The backwash water of the PP fiber filtering equipment is piped to newly backwashing wastewater storage tank. Then it’s pumped by backwashing wastewater transfer pumps to existing No. 4 aeration pond for treatment. Additionally a provisional nozzle shall be mounted on the backwashing wastewater transfer pipe for future connection to the No. 5 wastewater puddle treatment use.

The PP fiber filtering equipment is also equipped with chemical wash system. The wastewater after chemical washing will be pumped through chemical wash wastewater transfer pumps to discharge to existing wastewater buffer storage tank of A720 & A730 for temporary storage.
