Greetings,
I have a problem with dissolved organic carbon(DOC) in sludge. I need to lower the concentration of dissolved organic carbon in sludge. The sludge is generated from the treatment of waste water. The entry waste water in waste water treatment plant(WWTP) is with the following...
Hi springrise, thank you for you feedback there was some issue with the name of the file. I posted a link because for some reason even If I change the name doesn't work properly, but from the link it's working fine.

Hi bimr, pH controller which we have control pH = 8. The controller regulate through electrode how much CO2 need to dose so we can have pH = 8 in our waste water. I can say CO2 neutralization its probably the most economical option that I have. Because the expense for CO2 for just 1 month is not...
Hi springrise, I will explain the entire process. The waste water first goes to tank(1), after that is going to mediators(2), where the waste water is aerated, because of the high pH the waste water is passing process of neutralization, where carbon dioxide(4) is dosed according to the...
Hi springrise, I will make detail explanation. I'm working in thread dyeing factory. The only think I can tell you about dyes is that they are organic, dispersive, and they are not classified as harmful, hazardous and so on. In the process of dying we are using NaOH(from where the high pH come...
Hi bimr, I'm trying to reduce sulfates, from waste water. They are around 400-535 mg/l , I want to reduce them below 370 mg/l. My limit for sulfates are 400 mg/l. That's what I want to accomplish. There is no biological treatment in our ETP, there is only aeration, coagulation and precipitation...
Hi all, I make a lot of test with different type of coagulants, and the conclusion from all the experiments is that the coagulant(aluminum oxychloride) which we are using right now doesn't remove very well SO4 from the waste water, when we are using a little bit more than usual(which happen 1-3...
If you are not sure in something always check it. For example when your pH value is not with the expected value, search for the problems, always ask yourself a question when something isn't working fine, where is the problem. Always update your knowledge, you never know when something will be...
Thank you all for your responses. I bought expensive HDMI-VGA cable model Vivanco 45493 HDMI-VGA adapter for 21 euro, and I'm very content from the quality which this adapter provide.

Hi all, sorry about my stupid question, but I have problem with my new pc which I bought 1 day ago. My monitor is VGA-VGA (male-male), my new pc have DVI and HDMI exit only, so I want to know what type of adapter I need to buy HDMI-VGA or VGA-HDMI. I think I need to buy HDMI to VGA, because my...
Hi ashtree, we tested CFS which I described in my last theme " How to dose coagulant ", and we will make a test with the polyaluminum oxychloride. The formed sludge due to the coagulant used is beginning to rise from the transfer of waste water to precipitator through perforated tubes. We do not...
