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: 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: Na silicate soln. is reacted with a soln. of an aluminium hydroxy-chloride of formula Al(OH)xCl3-x, in which x is 1-2.5, in amts. such that the suspension obtd. contains 10-20 g/l SiO2 and has a pH of 6-8. The prod. is used as a flocculant in water treatment. The process does not require a maturation stage and gives little deposition on the vessel walls which is easily removed by washing with an Al salt soln. every 24-40 hrs. The prod. gives better flocculation results than normal activated silica or with an Al polychloride alone.

Abstract: Treatment of water by crystalline pptn. and decantation, comprises forming a homogeneous dispersion of the water, the reactants required for the pptn. and sepd. sludge from previously treated water. The conc. of crystal nuclei is sufficient for the pptn. to be almost complete before the decantation stage and to be completed during decantation. Used for treating drinking and industrial water or aq. industrial effluent contg. chalk, lime, bicarbonate, sulphates, phosphates etc., the process enables accurate closing and distribution avoiding crusting up of walls, pipes, etc.
