Effect of the industrial wastes purification system on the productivity of the yeast factory Lesaffre in Wolczyn

2014

The purpose of this work is to present that rearrangement of the industrial wastes purification system may cause the growth of the productivity. The analysis presented deals with the yeast factory Lesaffre in Wolczyn (Poland). Most of the industrial wastes (JW) produced there are utilized in agricultural fields (AF) but part of them is pre-treated in an evaporator battery (EB). The basic parameter determining amount of the JW to be utilized in the AF is nitrogen concentration for this element in excess can lead to destruction of plants. At present only the JW coming out from the first two separators are directed to the EB in the factory. In order to increase the yeast productivity of the fa…
