Hydrotech's Sludge Thickening Beltfilters
Your new key to efficient filtration of heavy-loaded water and radical reduction of sludge handling.
Fields of use:
- Food Processing
- Industrial Water
- Recycling Applications
The Hydrotech belt filter is designed to thicken sludge when used in conjunction with a polymer mixing system. Typically, sludge from a Hydrotech drum or disc filter has a dry matter content of 0.030-0.050% (300-500 mg/litre).
After passing through the Hydrotech Belt Filter System, the dry matter content increases to 8-12%. This means the volume of de-watered sludge has been reduced by a factor of 150-250!This radical reduction of sludge translates to lower costs for sludge storage, labor and handling.
The Hydrotech Belt Filter System compliments traditional solids handling practices such as vacuuming or brush and flush methods by eliminating settling ponds. When solids remain in the water column they break down, leaching nutrients (phosphorus, nitrogen) into the water. This is referred to as nutrient leaching. By directing the sludge to Hydrotech's Belt Filter System, the solids are efficiently removed from the water column. The dewatered sludge, no longer in the water column, is now in a form for easy transport and disposal.
How It Works
The Beltfilter System is also great for rough screening to remove large debris (leaves, sticks...) from intake water.
