To even begin to answer your question, I really need to know what question you wish to ask. I make my living in fluidics, and have no idea what you are trying to ask. What are you looking for, alkalinity, acidity, abrasion, what are you looking for?

I would assume that you would want to know if the waste water flowing into your WTP needs pre-treatment. This depends on where you are. There are specific codes you have to follow about waste water. Refer to them. Search what the codes tell you. If you are connected to the public waste water treatment plant, it would be different if your have your private waste water treatment plant. And by the way, what is your waste water treatment plant? Is it SBR, or what? What is actually important is the effluent. The degree of cleanliness of the water coming out is the final measure of whether you are code compliant or not. Some waste water treatment plants in advance countries produce effluents cleaner than what comes out of 3rd world country kitchen tap.

Also, I might add "WHY THE HELL ARE YOU ALLOWING WASTE WATER TO COME INTO A PLANT WHERE YOU ARE PREPAIRING MEAT, FOR CHRIST SAKE!!!"

ElectroCoagulate--simplest/most effective-you can start in Hours

Google it

If you have any practical difficulty-ask me.

Waste water from a slaughter house should have characterstic as described below

F.O.G (mg/l)

1000

SS (mg/l)

1560

BOD (mg/l)

2100

COD (mg/l)

4200

TKN (mg/l)

300

Yes in its Pre-treatment should include Screening, Coagulation, or seperation by creating flocs where suspended/ floating flats are seperated from liquid phase.

Oh Yeah!

We had a company come out and demonstrate the electro-coagulate process at our meat packing plant. What a great process. Took a sample, don't know how much as I was on vacation that day and wasn't invited besides, before pretreatment and ran it through the process. The engineer put it into a bottle and it looked like you could drink it!

But we don't want to use it at that point in the process. After the pretreatment to get rid of all of the fats/oils/grease we put it into anaerobic lagoons to siphon off the biogas, which we use to operate our boilers. Then it goes to the aerobic basins where it finishes up before it heads back out to the river.

Our concept would be to use the EC process after the anaerobic lagoon and right to the river. No aerobic basin, and a lot cleaner when it goes to the river.

I happened to see an article in a globalspec newsletter a couple of days before the company showed up. Everyone in the wastewater plant was pretty excited about the process. But it remains to be seen if the company buys into it or not. I personally think that it would be a benifit and keep the EPA more than happy.

Formulate a plan of what you have, what you need and current problems or issues.

Get the water tested, if you have'nt already, and post them so a plan can be devised

in an organized manner

for some natural minerals in the water can effect chemical treatment.

Most of what was considered as waste from inside slaughter houses is now a very valuable product worth more than the meat. Get an expert to advise you and make money from your effluent rather than cause environmental damage.

Pre-treatment may be necessary depending upon the FOG, BOD, COD content, pH level etc. What is the treatment capacity of your WWTP? As mentioned, electrocoagulation is a very effective way to deal with the problem. It also produces a minimal amount of low water-content sludge. A more conventional way of doing this will be anerobic treatment for 1-2 months followed by conventional aerobic treatment.
