Do I need to include a DO analyser in a DAF system for Desalination of seawater application?

Thanks ashtree and bimr for the informative answer. Is it normal to RO plant to make it online conductivity profiling? Will it cost a lot to have this smart technology? Is it useful?

How do you normally do the RO system conductivity profiling?

Hi ashtree, thanks for the wide experience you shared for the mbr possible fouling causes. The wastewater came from a soda making company with a COD content of 2,000ppm, TSS=50-100ppm, BOD=1500ppm & O&G=10ppm. Flow is 5000 m3/d. It has a coarse bar screen before it goes to EQ tank, AX, AE...

What are the probable reasons or causes why there is a chokage on MBR filtration?

Hi Ashtree thanks for the illuminating response. Yes it does have the re-circulation and still operating at normal flows. We will try the method above and see what will be the effect. Hopefully it can go back to original feed pressure since its a new system which is just less than a year.

Thanks for responding georgeverghese. Pre-filtration system has no problem at the moment. There is no leaks as well. Will check the feed-reject stream. What is the suggested reject to feed flow ratio?

What is normally the causes that spikes the RO feed pressure? CIP cleaning is done regularly. The NDP (Normalised pressure differential [Feed – Reject]) for 2 stages RO had hit CIP trigger limit for 2 months since operation. RO CIP was done after 4 months only. Is the current observation...
