Any hog farm biosecurity plan begins and ends with cleaning and disinfecting. The idea here is not to entirely sterilize the environment, but just to lower the pathogen load to a point in which disease is not transmitted. There are many steps involved in this, all of which can be streamlined with the help of the right pressure washing equipment.
Cleaning is the First Step
First and foremost, clean up the area by removing all organic material. You can do this with a broom, shovel, and / or scraper. Get as much solids removed as possible. If you have a farrowing house, this should be an easy step except for the point at which you must empty the sow feeders. However, if you are cleaning a semi-trailer, you will need to remove wood chips and other bedding, which can take time. Taking time to do this properly will significantly improve your results so be sure you are doing so.
Follow Cleaning by Washing
During the cleaning stage, you have picked up all materials so that you have a blank surface to wash. This is going to be the most time consuming of all the steps in the process, but it is the most important. Doing it correctly, with the right pressure washing equipment, can get rid of 99.99% of microorganisms. The purpose of this step is to get rid of all remaining organic matter, which includes feed, manure, urine, etc.
The best way to do this is via high pressure. You will need to look at your PSI (pounds per square inch of pressure) and the amount of water that you are moving, known as GPM. When you multiply the PSI with the GPM, you will get the effective cleaning units, otherwise known as ECU. If you have pressure that is too high, it can damage surfaces. For example, if you want to strip paint off a wall, 9,000 ECU will do it.
Deciding on the right ECU will depend on a number of factors. Your account executive at Hydro Tek can help you determine what your needs are. Just call us at 800-274-9376 for assistance.
A Word About Soaking and Detergents
If you have time to soak a surface, you can significantly cut down on how much time is needed to clean it. You can soak a larger area by using a sprinkler system to keep the room wet. If you are soaking at trailer, you can wet the entire trailer with a moderate amount of water and start washing at one end while the rest soaks.
You can also use specialty detergents that are created specifically to break down manure and similar organic matter. Essentially, this is likely using soap to clean your hands. Yes, you can wash your hands with just water but soap can help the process go much faster.
