WHY EFFICIENT SLU IS CRUCIAL All water on earth circulates in a closed loop. The total quantity of water on earth amounts to 1.4 billion cubic-kilometers, 96.5% of which is sea water in the oceans. Only 3.5% is fresh water. However, more than half of this fresh water is in the form of ice on the poles, glaciers, and permafrost. Clean water is becoming an increasingly important raw material. That’s why municipal and industrial waste water treatment is also becoming increasingly important. 2 A key process in waste water treatment is the efficient separation and, as far as possible, mechanical...

UDGE TREATMENT The Five Most Important Parameters in Sludge Processing In order to find the optimum, and above all, most economical solution for your dewatering process, you should always consider all the important parameters, when selecting the appropriate separation equipment. The five most important parameters are as follows: ∙ Dry-substance content ∙ Capacity ∙ Polymer consumption ∙ Energy consumption ∙ Back-contamination in the clarified liquid (separation efficiency) Flottweg is your competent partner for the right selection and dimensioning of your separation equipment. Many...

Master Saver ∙ dditional energy recovery thanks to the A Flottweg Recuvane® System ∙ educed energy demand of your decanter of R up to 30%* ∙ Easy retrofitting, quick pay-off ∙ Existing separation processes remain unchanged *depending on the pond depth and the characteristics of the sludge ∙ ully automatic adjustment of the bowl and the F differential speed produces optimum dry substance levels in the dewatered solids at any time, even in case of varying conditions in the feed ∙ lready 4.0 compliant – all options for remote A monitoring and maintenance are...

FLOTTWEG FLOTTWEG OSE DECANTERS OSE DECANTERS for Sludge Thickening Customer Benefits Versus Other Thickening Techniques In sludge thickening, surplus sludge generated during the biological stages is concentrated from 1% or less dry substance content to 5 – 8% before it is pumped into the digester. As a result, the amount of sludge is reduced by 90 to 95%. Most important point ∙ olids concentration in the discharge is adjustable S and controllable ∙ Optimized feed of the digester ∙ Increased gas yield and degradation rate The Flottweg OSE Decanter (OSE = optimal sludge thickening) was...

FLOTTWEG FLOTTWEG HTS DECANTERS® AND HTS DECANTERS® AND XELLETOR DECANTERS XELLETOR DECANTERS for Sludge Dewatering Regardless of whether the sludge is transported after dewatering, reused as fertilizer, disposed of in landfills or incinerated – maximum dryness is the most critical factor. Other key factors are cost efficiency in terms of polymers, energy, water and spare parts, as well as continuous, automatic operation at minimal costs. All these critical design features were already taken into account at the beginning of the 1970s. The result of this continuous development is the...

HOW THE FLOTTWEG DECANTER WORKS A decanter centrifuge can be viewed as a settling pond wrapped around an axis. In the settling pond, solid particles, which are heavier than the liquid, settle to the bottom driven by gravity and build up a sediment layer on the bottom of the pond. In the rotating bowl of the centrifuge, solid particles, which are heavier than the liquid, move to the inner diameter of the bowl driven by centrifugal force and build up another sediment layer on the inner surface of the centrifugal bowl. Since the centrifugal force in the decanter is approximately 3000 x g...

Inside the bowl, there is a scroll conveyor for the The bowl of a decanter has a cylindrical-conical continuous discharge of the sediment which is shape. It rotates at a high speed creating the packed on the inner surface of the bowl wall. centrifugal force needed for the separation. The scroll conveyor rotates at a speed relative to the bowl speed. This differential speed is created by a rotating gear box at the drive end of the bowl. The sediment is delivered out of the pond on the conical end of the machine, also called the dry zone, before it leaves via discharge ports on the conical...
