Abstract: Method for treating water in closed-circuit fish-farming systems comprises passing the water through a filter bed of solid material into which an oxygen-contg. gas is injected. This eliminates nitrogenous pollutants and replaces consumed oxygen in a single stage and, if necessary, also removes solid wastes. The flow rates of gas and water are controlled so that the pH is maintained at 5-9, esp. by stripping CO2 formed during the nitrification. Adequate purificn. is achieved in a single stage and treatment is carried out outside the fish-raising pond. Little or no fresh water needs to be supplied and stock levels 3-5 times higher than those generally used can be maintained. The filter material acts as a support for the denitrifying bacteria and the system can cope with large variations in the degree of nitrogen pollution.

Abstract: The water contg. 20 mg/l of ammonia is passed up at least one bed of granular material seeded with bacterial microorganisms. Oxygen in added to the water current before it is injected into the bed, which results in the release of oxygen bubbles throughout the filtration bed. The process is carried out using a bacterial bed of material such as sand of carbon with injection means for passing oxygen or an oxygen contg. gas into the current. The process is particularly applied to drinking water. It enables addn. of oxygen according to the ammonia content and the movement of the bubbles avoids blocking of the column, releasing excess biological mass which can be eliminated.

Abstract: Réacteur qui comporte trois cuves en série une première cuve de contact (1) recevant l'eau à traiter et destinée à l'action oxydante directe et rapide par l'ozone qui est introduit dans ladite cuve et mis au contact du liquide à traiter (4); une seconde cuve de contact (2) destinée à assurer la désinfection du liquide et dans laquelle on injecte la quantité d'ozone nécessaire au maintien dans le liquide à traiter de la concentration en ozone résiduel nécessaire à la désinfection de l'eau et ; une troisième cuve de contact (3) destinée à assurer l'action radicalaire de l'ozone dans laquelle on injecte, outre de l'ozone, une quantité de péroxyde d'hydrogène destinée à augmenter la quantité de radicaux OH disponible pour la réaction avec les polluants à éliminer par oxydation, l'eau traitée étant évacuée de cette troisième cuve.

Abstract: A reactor which includes three tanks in series, namely a first contact tank (1) which receives the water to be treated and intended for the direct and rapid oxidizing action by ozone which is introduced into the said tank and set in contact with the liquid (4) to be treated; a second contact tank (2) intended for disinfecting the liquid, into which tank the quantity of ozone is injected which is necessary for maintaining the residual ozone concentration necessary for disinfecting the water within the liquid to be treated; and a third contact tank (3) intended for providing the radical action of the ozone, into which tank, in addition to the ozone, a quantity of hydrogen peroxide is injected which is intended to increase the quantity of OH radicals available for reaction with the pollutants to be removed by oxidation, the treated water being removed from this third tank.

Abstract: Denitrification of water using ethanol as carbon source is characterised in that the ethanol is denatured with a phosphorus cpd. (I) before being introduced into the denitrification process. More specifically, the process involves biological treatment of water with bacteria which are capable of converting NO3 ions to N2 in the presence of ethanol. Unlike other denaturants (e.g. acetone, isobutanol or propylisobutanol), cpds. of type (I) do not inhibit bacterial growth; in addition, they supply P as an essential nutrient.

Abstract: In a system for decantation treating of liquid containing therein suspended material, the liquid to be treated is pulsatingly introduced into the bottom of a sludge bed and pulsated therein. The liquid is passed upwardly through the sludge bed at a predetermined speed whereby the suspended material is agglomerated and removed from the liquid. The liquid is forced through the sludge bed from the bottom to the top thereof in paths which are inclined both to the horizontal and to the vertical. Specifically, the liquid passes generally upwardly through an assembly of inclined flow control devices which are positioned within the sludge bed throughout substantially the entire height thereof. Sludge settles within the inclined passageways between the flow control devices for a slight distance until the sludge contacts an inclined bottom wall. The sludge then slides downwardly in an inclined manner along the bottom wall in a concentrated path or current. This concentrated path or current forces the liquid upwardly and away from the bottom wall, thereby creating a generally upwardly moving inclined path or current of liquid. The settling sludge and rising liquid thereby form concentrated currents in parallel but opposite inclined directions and increase the tendency of the suspended material to be agglomerated from the liquid.

Abstract: The water is passed upwards through a bed of a granular material on which are fixed bacterial microorganisms which provoke the nitrification and/or dentrificiation of the water. The internal recirculation of the support, such as sand, results in rubbing whereby the excess microorganisms are sepd. and evacuated from the upper part of the bed. The process is carried out in appts. which contains at least one hydro-ejector to circulate the material. It is used to treat water for drinking. It enables regeneration of the column, ensuring good yields and avoiding blockage.
