摘要:
The invention provides the use of a water-soluble biocide as an uncoupling agent at an effective amount to control bacterial biomass in an aqueous system. The invention also provides a method for controlling the growth of bacterial biomass in an aqueous system. The method comprises adding to, or contacting with, the aqueous system an effective amount of an uncoupling agent which is a water-soluble biocide. In a preferred embodiment the method comprises contacting an effective amount of an uncoupling agent which is a water-soluble biocide directly with the bacterial biomass in an aqueous system.
摘要:
The invention provides the use of an effective amount of a non-oxidizing water-soluble biocide in the improvement of sludge quality by reducing the sludge tendency towards bulking, wherein the biocide comprises an alkyl-substituted phosphonium compound, an alkyl-substituted phosphine, an alkyl-substituted phosphine condensate, or a polymeric quaternary ammonium compound.

摘要:
A process for decontaminating water contaminated by emergent pollutants or micropollutants, includes a step of injecting the contaminated water into a device having a vertically filtering planted organic filter, which planted organic filter includes: an inlet for the contaminated water; an outlet for treated water; filtration and decontamination elements interposed between the inlet and the outlet, characterized in that the filtration and decontamination elements take the form of a planted organic substrate composed of a compost and insoluble aggregates, making it possible for the organic substrate to maintain a permeability of at least 40 litres per hour per m2, preferably at least 70 litres per hour per m2 and particularly preferably at least 100 litres per hour per m2. A device for decontaminating water contaminated by emergent pollutants or micropollutants is also described.
