Working principle:
AquaBelt is a gravity belt thickener for municipal sludges and all other sludges that fl occulate. It works on the principle of separating liquid from solids by gravity drainage through a slowly rolling belt cloth.

AquaBelt is equipped with a patented sludge polymer mixing valve with an adjustable lever arm that is set at approx 70% open to ensure suffi cient sludge/polymer turbulent mixing. A sludge retention tank, also known as the fl occulation chamber is fi lled from the bottom and then rises up over a weir to ensure even distribution onto the belt.

Sludge ploughs force the sludge into lanes which allows free water to run through the belt cloth where sludge is not present, thus enhancing the pre-dewatering process. Sludge ploughs can be lifted to allow for removal of rags etc. 
 

Features:
• Patented ramp for enhanced thickening performance
• 316 stainless steel construction or 304
• Robust belt steering and & tension mechanism
• Fully enclosed design to eliminate aerosol and odour
• Externally adjustable ploughs
• 20% increase in fi ltration area
• Few moving parts
 

Benefits:
• No spill design
• Minimum operator input
• Low power consumption
• Low polymer usage
• Low internal volume to minimise costs of odour control equipment
• Cost effective thickening
• Suitable for outdoor operation
• No additional fl occulator and mixer requirement
• Higher percentage thickened dry solids
• Higher throughput
