Operational application of the optimised conditions of aggregation-mixing on the separation properties of aggregates formed during the purification of surface waters
Original language description
The optimisation of agitation conditions decisively influences the properties of suspension formed during the chemical purification of water. It was found most beneficial with the application of the high mean velocity gradient G > 100 s-1. The velocity gradient G and the time of agitation T must be optimised when designing the technological arrangement of the waterworks. The results obtained from the application of the HRC technology proved that the high G value is instumental in achieving a very high upflow velocity in the clarifiers and improved the dewatering characteristics of produced sludge. The results obtained from the application of the FLGM proved a considerable extension of the filtration run of rapid gravity filters. Operation of the FLGM in A-mode resulted in extension of filtration run by 40% and in S-mode by 70%.
