Sludge frezing for dewatering. The effects of sludge freezing have been recognized for over 50 years, but until recently a generally applicable design procedure was not available.... A cycle of freezing and thawing converts sludge from a jelly-like consistency to a granular material that drains readily.  1, record 1, English, - sludge%20freezing

Distribution of Permafrost.- Permafrost underlies more than 50% of the ground surface of Canada. The two major divisions of permafrost are continuous permafrost and discontinuous permafrost. In the continuous permafrost zone, permafrost occurs everywhere beneath the ground surface except large bodies of water. In the far north, it may be more than 500 m thick. The discontinuous permafrost zone is broken into two other divisions: the widespread permafrost zone, where permafrost underlies 50-90% of the land area, and the sporadic permafrost zone, where it occurs mostly inpeatlands and underlies 10-50% of the land area.  3, record 2, English, - permafrost%20distribution

The total annual freezing index has been used to predict permafrost distribution, and the design freezing index is commonly used in engineering to estimate the maximum thickness of lake ice and the maximum depth of frost penetration in the ground.  1, record 2, English, - permafrost%20distribution

Distribution du pergélisol.- Le pergélisol est sous-jacent à plus de 50 % de la surface du Canada. Les deux types principaux de pergélisol sont le pergélisol continu et le pergélisol discontinu. Dans la zone à pergélisol continu, le pergélisol est présent partout sous la surface du sol, à l'exception des grandes étendues d'eau. Dans le Grand Nord il atteint plus de 500 m d'épaisseur. La zone à pergélisol discontinu comporte deux sous-divisions : la zone à pergélisol étendu, où le pergélisol est sous-jacent à 50-90 % de la surface, et la zone à pergélisol sporadique, où il est présent surtout sous les tourbières et est sous-jacent à 10-50 % de la surface.  1, record 2, French, - distribution%20du%20perg%C3%A9lisol
