A foul, odorous anaerobic lagoon problem can usually be <br /> corrected by use of a mechanical aerator, and nitrogen <br /> Content of affluant can also be further reduacd. <br /> However, a significant operating cost frill be incurred. <br /> 11. Addition of foreign material -- long-s emmed getation, <br /> discarded feed, egg flats, egg shells, trash -- should <br /> be prevented. Solids separation may be ACCOMplishad <br /> With mechanical Separators or by gravity settling <br /> basins. <br /> I <br /> 12. Be conscious of sludge 1Qvel in the Ia400n, and remove <br /> before more than 60 parcent of the treAtment volume is <br /> occupied! Test autridnt and miner; content of sludge, <br /> and use environmentally safe land application methods. <br /> i <br /> 13. Remove lagoon effluent at least annually to control <br /> overflow, and to regulate salt concentrations. Add <br /> - fresh water if necessary to maintain minimum design <br /> volume. <br /> j <br /> s <br /> 14. Locate irrigation and flush recycle pLz p intakes about <br /> 18 inches beneath the Lagoon surface, end as far from <br /> waste inlet(s) as possible. <br /> 1S. Properly ground electric pump honmings ' to assure that <br /> stxay voltages do not contribute to salt deposits on <br /> pump intimal surfaces. <br /> 1S. Development of. a pink or purple color in the lagoon <br /> should not be, a concern= this is an indicator of <br /> establishment of aulfur-fixing bacteria which aid in <br /> reducing odors from hydrogen sulfide production. <br /> Raterowed <br /> American Society of Agricultural Engineerst 1990.
