Hello,
I am putting together a short presentation for septic system installers. The basic focus of the presentation is ways that the contractor can ensure a smooth working relationship with the engineer. I am looking for common generic problems encountered by engineers when working with...
Hello,
I am looking for information on converting nitrate to inert nitrogen gas (denitrification), without harmful byproducts, for use in treating domestic wastewater. Most processes I've been introduced to use biological means to accomplish denitrification, so I was wondering if anyone could...
Hi Alternety,
We had Maytag come into our office and give us the spiel on the 4200 a month or two back. They only provided part of the manual in hardcopy form, and its not the technical part, unforunately. This link may give you some idea of the specs...
Hi Masuk,
These definitions from Google...
A surface phenomenon which may be either absorption or adsorption, or a combination of the two; often used when the specific mechanism is not known.

Hello all,
As many of you are aware, land application of septage and treatment of septage at WWTP's are the two predominant ways to deal with septage. However, with the tide turning against land application of untreated septage, less popular ways of dealing with it should be coming into more...
Hello,
Does anyone know where I can find any data on whether hydrocarbons (gasoline, diesel) have any effect, such as degeneration over time, on Zenon membranes (Zeeweed)?
There's a water plant that's having some problems with their filtration system, and we're trying to find out if the culprit...

Thanks in advance.

I assume you are looking for corrosion guides? Other people probably have better guides, but http://www.leightonstone.com/ashcroft/Corrosion_Guide.pdf
has a pretty comprehensive list of chemicals and their compatibility with some metals, alloys and polymers.
If you have a...
Hello,
Thanks for all your help, its has been very beneficial to not have to thrash around blindly on the internet. I've located a couple of helpful sites thanks to your information.
P.S. I'm not Russian, I'm actually from Ontario, Canada. Just a handle I've been using using for a long...
Hello all,
I have been given the dubious project of obtaining and compiling general cost estimates for assets in water treatment and wastewater treatment plants. It is a fairly comprehensive list, so there are a tonne of items and they want me to find as many as I can. If I chase down each...
Hello,
I am currently trying to mount a pH probe in an industrial sanitary sewer. The sewer has occasional large solids travel through, and it is imperative the probe does not block the objects, and plug up the flow. The probe has to be removable from the surface (12 feet) through a...
First I want to thank everyone for responding.
Second, the plant used to just paint some SS pipe they ran through the hypochlorite vat. I want to know if anyone has opinions on whether painting the SS pipe would help prevent corrosion/metal contamination, or if that is just a band-aid...
ApC2Kp,
Finally got some more information on the situation.
The vat is made of concrete, and is not a candidate for heat tracing. The hypochlorite solution is 12%, and the heating media is going to be water, not steam. Also, the heating coil will only be exposed to the solution for a week at...
Hi,
I'm trying to nail down a good, cost-effective material for heating a vat containing sodium hypochlorite, for the purpose of membrane cleaning. The temperature is only going to be up to 30 degrees Centigrade. I'm getting mixed signals on 316 steel, some information and companies highly...
