Manure in a hog confinement area contains high levels of ammonia and hydrogen sulfide gas. While the odour is certainly uncomfortable for humans, a high level of gas makes young hogs irritable, reduces their feed conversion rate and makes them more susceptible to viral infections, like pneumonia.

With the application of BIOLOGIC™ SR2 in confinement areas, ammonia and hydrogen sulfide gases are reduced to safe levels. Controlling these gases is critical, especially in farrowing and nursery houses where younger pigs are contained.

High gas levels can also cause serious ill-effects on a persons health. Many people may not notice the high content of gases in water or in air because in time they become accustomed to it.

Up until now, this has been a serious problem because the solution was to cever up the foul odours with masking agents.

BIOLOGIC™ SR2 is effective in eliminating the harmful odours and does this by actually reducing the odour at the source rather than masking it.

Most of the bacterial population within a facultatve lagoon are facultative bacteria which are stimulated with the addition ol BIOLOGIC™ SR2. Some of the results which can beo expected with the addition of BIOLOGIC™ SR2, to a facultative lagoon, are as follows:

1) A decrease in the amount of oxygen required for biological degradation which results in more complete and efficient biological reduction of the wastewater with an equivalent retention time.

2) The dissolved oxygen level throughout the lagoon can be expected to increase.

3) An increase in dissolved oxygen eliminates hydrogen sulphide gas emissions resulting in complete odor reduction.

4) Increased biological treatment efficiency resulting in a substancial increase in effluent and supernatant quality. A significant decrease in Suspended Solids, BOD, Total Nitrogen and Total Phosphorous can be expected.

5) Increased anaerobic digestion efficiency resulting in more complete degradation of solids and better settleability which results in a dramatic decrease in sludge volume.

6) Significant decrease in the total volatile solids of the sludge can be expected.

7) Sludge concentation and/or dewatering problems are reduced due to the increase in sludge settleablilty.

8) Within a short time (hours or days) observation of bubbles on surface that look like rain.

9) The water will start to clear showing the settling of solids within the lagoon.
