Sludge Dewatering

  1. 1.
    thick, soft, wet mud or a similar viscous mixture of liquid and solid components, especially the product of an industrial or refining process.

  2. Such a simple word, suggests the way it looks and covers a multitude of materials, many very different from each other. The common denominator, despite appearances, is that they generally have a very high water content. Sludge disposal is rapidly becoming one of the greatest costs in running an effective wastewater treatment plant. Water Clean are committed to helping you reduce those costs and therefore increase your overall company profits.

When looking at a sludge from a treatment process you could be forgiven for thinking there were more solids in it than actually there is. A typical DAF plant sludge will be approximately 5% solid-or 95% water! So when your next 20 tonne load of sludge goes off site by tanker-remember it may be 19 tonnes of water and 1 tonne of solids. The good news is that this creates a cost saving opportunity-and one which will continue to return profit to your business for as long as you capitalise on it. The theory is simple. Increase the solids content to reduce total material removed from site by tanker and put more of the water down the drain. 
Fortunately, we are here to help you with this task which comes in two stages:

1) Make a good liquid-solid separation of the sludge so that the water is ready to separate effectively from the solids. This means getting the chemistry right.

2) Make a good physical separation of the liquid and the solids so that as much water as possible can be "squeezed" out of the sludge and disposed of to drain. This means getting the equipment right.

Water Clean have teamed up with some of the best players in the mechanical separation industry. Combined with our ability to chemically engineer the water to "want to leave" it produces a great opportunity for you to save money on your effluent treatment costs.
