A process for treating effluents loaded with organic material, particularly wine-making effluents essential in the form of wash water, comprises pouring the effluents to be treated into a storage basin (1) and actuating a recirculation circuit (2) between this latter and an oxygenation reactor (3) for the effluents, actuating a superoxygenation device (4) when the volume of effluents stored is too great to avoid passing into anaerobic phase, then stopping the superoxygenation and maintaining the recirculation at a minimum level avoiding the passage into anoxia of the effluents, when these latter fulfill certain minimum pollution conditions. The effluents are poured over at least one purification body (5) and the purified effluents are withdrawn, until there is substantially nothing left but residual decantation sludges more or less mineralized, in the storage basin (1). These latter are treated to delay the organic components present and to lead to a substantially inert mineralized sludge.

Process and installation for the treatment of effluents loaded with

An automatic process in which after the press is filled and before starting a normal pressing cycle the flow rate of liquids is measured continuously without applying any pressing pressure. The tank is then rotated and the minimum and maximum values of the flow rates are determined and then compared respectively with predetermined values. Based upon this comparison and as a function of the results of the comparisons there is performed a preliminary pressurized draining of the materials to be pressed while at the same time the orifices for evacuation of the liquids are checked for possible clogging. These operations are repeated until the results of the comparisons no longer warrant a pressurized preliminary draining and subsequently initiating the normal pressing cycle.

Process and apparatus for the control and the adjustment of a press during a juice extraction operating having at least one pressure increase sequence and measuring and comparing to a predetermined value the rate or the amount of liquid extracted before, during or after the pressing, or the partially pressed materials to be pressed remaining in the press after the pressing, and then using the resulting value of the difference of the rates or the amounts of extracted liquid and the value of the expected rates or amounts or the amount of materials to be pressed remaining in the press, if applicable, partially pressed, to begin, continue, interrupt, modify or complete the process of extracting the juice. The process is at least partially programmed.

A process for preparing liquid treating agents, stable under storage, especially for improving the wrinkle-free characteristics of cellulosic textiles treated with the liquid in which urea is condensed with formaldehyde in an aqueous solution in the presence of glyoxylic acid. This condensation is carried out in a first step using an acid pH between 2 and 5 with a molar ratio of urea/formaldehyde/glyoxylic acid of 1 : 2 to 10 : 0.03 to 0.6 and at a temperature between 20.degree. and 100.degree. C. In a second stage the reaction is carried out at a slightly acidic pH between 6 and 7 at a temperature between 20.degree. and 60.degree. C with addition of a fresh quantity of urea and eventually a fresh quantity of formaldehyde in an aqueous solution so as to obtain an overall molar ratio of urea/formaldehyde/glyoxylic acid of 1 : 1.5 to 3.5 : 0.03 to 0.6.

A latex composition sensitive to heat, particularly for use as a binder for nonwoven fabrics, comprises 0.05 to 5 parts by weight per 100 parts by weight of a latex (as the dry solids) of a urethane-oxyalkylene copolymer having the formula ##STR1## IN WHICH R represents an aliphatic group and/or an aromatic group which can contain a biuret group, a urethane group or isocyanate groups, R' is hydrogen or a lower alkyl radical having 1 to 8 carbon atoms (straight or branch chain), an aryl radical or an alkylaryl radical, x is 0 or 1, y is always greater than 2 and x+y is also always greater than 2; n has a value ranging between 2 and 4 inclusive while p has a value at least equal to 5.
