Chemical Recovery System

I DO NOT HAVE MY COMPUTER NOW ONE THAT IT HAS A DESIGN REGARDING TO A PROJECT VERY SIMILAR AS YOUR´S

ONCE I GOT BACK IT TO ME I WILL SEND THE DATA WITH YOU

RIGTH NOW DUE TO THAT PROJECT I AM STUDING TO GET A MASTER DEGREE IN CHEMICAL ENGINEERING EVEN I AM AN ELECTRO-MECHANICAL ENGINEER

I THINK BY NEXT TUESDAY I WILL SEND THE PROJECT IDEA TO YOU

FIRST I ADVICE WHAT PRODUCTS YOU WILL GET

AND AFTER THEIR INDUSTRIAL USE

ANYWAY KEEP IN TOUCH

MY BEST REGARDS

It is pretty neat that you have concerns about a problem of this nature. I wonder how many other people in your position would have done the same. Your instincts might be telling you something that you should be very aware of.

This may be a silly question, but you might be wording your question with general information that is not specific enough for anybody to give you an answer that you can use or give you some direction for research.

If you want to find an answer to a problem you have to know what the problem is. You might want to include what is exactly in the water and how much of it. This might give us a starting point and help us advise you what you need to look into. I would not take anybodies recommendation unless you can find someone to support their answer.

If you are trying to find a more cost-effective method for chemical treatment, the first thing I would do is look at the treatment and where you are buying it from. You could be buying it from a distributor who might believe that some government worker are too stupid or lazy to go price shopping so they might be fuckin' your government pretty hard.

On a funny note: it may be its your bosses brother-in-law who is selling the stuff to your company. That may not be a hill you want to die on (another way of saying, "you pick your battles"). I hope that this is not true.

If you can get the bottle, look at the ingredients, you might find something similar on the shelf of your grocery store. Sometimes we overlook the simple ideas. I remember a "former" vendor of filtration media told me to clean my filters with a special chemical. My shop guy thought it was too expensive and found a bottle of Drano that did the same job for a third of the price.

To find the possible environmental impact of what your organization is doing or having on the environment, go to www.epa.gov and use the water contaminate as a search word. The US government has lots of reports and impact studies over the years.

Your country might have its own version of an environmental ministry that you should look into first.

Yes, we need more details about what you are using for chemical treatment and what is your system. Generally, for evaporative coolers (I'm thinking forced draft evaporative cooling towers like a "Marley" brand name), the chemicals needed are algicides/ biocides, wetting agents, and antifoam agents (for when you get too much wetting agent).

The chemicals that cause the most environmental concern are the algicides/ biocides because they are low concentration poisons. They keep stuff from growing in your tower, and in the high humidity/ warm environment they are critical to keep from fouling. Some are expensive, such as bromine compounds. Alternatives, as one poster has said, can be pretty cheap. Just be sure that the materials of construction in your system can deal with the alternative algicide/ biocide without corroding. For example, regular Clorox(Registered Trademark) chlorine bleach is a great algicide/ biocide in the right system, but don't use it in systems containing aluminum, etc. Clorox(registered Trademark) breaks down into salt water, so is pretty environmentally benign after it does its anti-microbial work.

Some older tower treatments were chromium based or arsenic based, and those were real bad guys. We don't use them in the US anymore.

Wetting agents are surfactants like liquid soaps. They make the water wetter and improve heat transfer by washing fouling off the heat exchanger tubes, as well as transfer contaminants through the system to settle out in the pump sump. Anti-foams are put in when you overdose with wetting agent and the tower starts shooting soap suds out the top. (Yes, this happens...I've done it).

Recovering the algicides/ biocides you are using now is, of course always possible, but the costs are terrible. After all, engineers can make any system with enough time and enough money and no expectation of return on investment. Better option is to use chemicals that break down into harmless entities after use.

Anyway, we need more information to help you out more.

Right now I am evaluating whether or not to specify this non-chemical system that may interest you: conservationsolutions.com/cfwt.html

If your system is appropriate for ozone use, a white paper discussion can be found here: p2pays.org/ref/19/18055.htm

Either may save you money, as well as eliminate environmental concerns.

First of all, we need to know what type of chemicals you use to control scale formation, whether organic or in-organic, commonly used chemicals to control scales are either phosphonates or phosphates.

Bleeding condensing water is essential to the success of your water treatment program, to avoid scale formation.

However, you may eliminate this loss by converting the bleed-off water to your non-potable water supply line. One way of doing this is by constructing an underground water cistern or an overhead water tank, where you may collect or deposit all bleed off water and re-use the water to your building bathrooms to flush-off toilet bowls, or for other purposes such as gardening etc.

Two of our client in manila, philippines did this and it was a great success.

asia pacific chemicals

That happens to be the business that I am in. Perhaps all you need is a second opinion from someone.

If you could tell me where you are located, I could find someone would could offer you some advice.
