Membrane Solutions' UF Plant
At present, Client’s Process isn’t too complex: Grille Screen + Primary Sediment + Dosing Chemical + UF + Chlorine disinfection
Issue 1:
Dosing Al2O3 to reduce color of raw water, Because Influence’s Color up to 200, Client dose lots of ppm Al2O3 and ETI Soda, meanwhile, volume of balance mixed tank is too small to be enough mixed chemical. Influence high TSS, Effluence up to 8ppm, so security filter bag have to clean per 4 hrs
Suggestion:
1. Build new balance mixed tank and monitor the value of TSS. Ensure reasonable TSS before enter bag filter and Effluence of UF system.
2. Recommend other chemical to replace Al2O3 and ETI Soda
Effluence & Influence
Issue 2:
Total recycle working time revised from 2400sec to 1800sec, some set even to be 1500sec to backwash operation. It will higher effect UF system flux and lifespan. Feed pump without frequency PLC control, they have to handle operate.
Suggestion:
1. Work together to solve high color issue to ensure system’s flux and lifespan;
2. Add frequency device in new UF system order.
Backwash
Issue 3:
Client still don’t install CEB and CIP Dosing device for UF system
Suggestion:
Add dosing timing, concentration and recommend pump and tank to reduce pollution for UF system;
Water Plant
Issue 4:
All of system is ISO DN standard, but local is EN JIS Standard, Once broken, whole system would
be stopped. Meanwhile, UF connection is PVC material, there are broken risk during transportation;
Suggestion:
Prepare enough pipe spare part and change UF connection from Screw to Snap hoops
Issue 5:
PLC system can’t connect with PC, the design system have some different set, local clients can’t remotely revise parameter but manual revise on touch screen.
Suggestion:
Prepare PC for new UF system order
PLC Cabinet
Touch Screen
All above, MS’s UF system still good work from 2016. The reason why those issue occur is that prefiltration process is too simple to meet UF system requirement. Of course, we will work together with our client to solve their present and potential problem.
