0707 jari001 Thanks a lot MJCronin thanks anyway but just take it easy bro here it is a forum if any one know a simple information which can help just share with others without too much philosophy it is as simple as that only there is a recommendation for each chemical for example antiscalant...

Dear all, In water treatment plant there are many chemicals used and as I know there is a concentration of each chemical recommended from the supplier according to raw water analysis. Please anyone can explain me how they recommend the concentration of chemicals or anyone know the relation...

Thanks all for replying @EdS yes that is true the ss 316 is the best material to treat high pressure and avoid corrosion problem. @Dhurjati yes am trying to find even 304 but still not available because of block of some areas means we don't have many choices because of this pandemic...

hello, there is too much leakage in our ss pipe we tried to weld many times but not succeed also stain less steel 316 is not available now in the market because of this pandemic that is why am trying to know which type of material we can put in place of stainless steel pipe? we have RO plant to...

Dear all, Please is there any specification for concentration of chemicals in ppm for each water (with specific use) means for example we have sewage water we will treat it with RO to product water to use in chiller and cooling tower after and I find this equation ppm= ltr/h* dilution ratio...

Hello, Dears Our RO plant is working for more than 5 years now and we need to check spare parts and replacement for the majority of parts. I searched for these parts and I prepared quotation for. I should prepare now a technical report to convince the client that we need to replace some items...

Dear all, Thanks for replying For who told me about new material, yes you have reason and that what i suggested but now it's very difficult to find material the majority of workshops and shops are closed and some industrial areas are closed also so that is why we are trying to fix without...

Thanks a lot for replying, I already give it back to the workshop and I asked them to remove all the old welding and corrosion and make grinding then we can weld again. we will see maybe if they clean it good it will work the argon welding is stronger one. Thank you all

thanks for replying, here is photos

Hello, there is on ss pipe in small RO plant which was not working maybe for 1 or 2 years now we are checking to restart this plant the proble in the ss pipe there is leakage in elbow and T our workers tried to fix with normal stainless steel welding rod 2 times but still leak coming also we...

Dear all, thanks a lot for replying I found one equation saying ppm = dosing pump flow*specific gravity*dilution*1000/feed flow. I think for dilution the mean how many liters of chemical we should put and mix with water in the tank. Really this is the first time I see this equation and am...

@ashtree thanks for replying and yes housed in a pressure vessel with back en caps.

Hello, I want to understand in general how to arrange percentage of dosing in the dosing pump? and what is the relation with the concentration of chemicals we need to add? and how we calculate the quantities? Thanks in advance.

@mk3223 thanks for replying, ok now already our plant is not working 100% because there is maintenance in the chiller this period so we are only making the plant working for some hours a day and also we are already operate streams separately means for exemple UF stream 1 and RO stream 3 ...

we have RO plant with 3 streams same procedure which start by carbon filters them mechanical filter then Ultra Filtration Modules then Reverse Osmosis Membranes. I found 2 streams with low inlet and outlet pressure in the mechanical filter and low flow rate from the UF also conductivity in the...

@TiCl4 Thanks for replying
