Dangerous dust cut

PROLONGED exposure to high dust concentrations in pig units can be very damaging to human health, says cleaning systems specialists ALTO.

Now, the company has developed a Dust Binding System which it claims can eliminate up to 90% of breathable dust endured by pig producers on a daily basis.

Designed to work with ALTOs 44C3 KSA-1 and KSA-2 stationary pressure washers, the system sprays a very fine mist of water and vegetable oil.

Sprayed four times a day for 20 seconds, the mist attracts and collects dust particles, which then settles and binds to surfaces in pig units.

The vegetable oil is stored in a 25-litre container, mixed with the water through a venturi system and atomised inside buildings using a sprinkler system. After dust "binds" to surfaces, it can be washed away with plain water using a pressure washer, and be set up to work in a number of different pens inside pig units at once, says ALTO.

The company claims it is possible to "dust-bind" in two pens, wash down in a third by disconnecting the oil injector – together with soaking a fourth pen.

A sensor-controlled temperature facility also enables livestock to be showered with water mist to reduce the ambient air temperature in pens on hot days. &#42
