When a Decanter is used in conjunction with a Eutek TeaCup^® solids classifier, the grit underflow and washed abrasives require no further washing before dewatering. This underflow can be pumped or flow by gravity to the Decanter for clarification and dewatering. Degritted overflow from the Decanter can be returned to the plant headworks.

The Decanter comes in three basic configurations to match local disposal trucks or equipment configurations: front-loading, rear-loading, and self-dumping. Standard features include a galvanized steel construction with female pipe thread connections. Optional features include quick disconnect fittings and hinged plastic covers.

Advantages

• Retains 75 micron grit and larger when used with a Eutek TeaCup^® or Eutek SlurryCup™ grit washing unit
• 1 and 1.5 cubic yard capacities
• Standard hot-dipped, galvanized finish (or stainless steel)
• Meets ANSI Standards for safety and compatibility
• Reduces abrasive wear & fouling of solids-handling equipment
• Easy disposal of dewatered solids
• Cost effective alternative to conventional dewatering systems
• Long product life
• Matches standard solids refuse trucks
• Available in front-loading, rear-loading, or self-dumping options

The Decanter quiescently settles high-density solids to retain grit and abrasives. A wedgewire dewatering screen allows free water to drain out without releasing captured grit. The Decanter is portable, mounted on four polyurethane casters suitable for movement on a smooth, hard floor.

Q. What is the Decanter?

The Decanter is a cost effective dewatering bin, suitable for use in smaller plants. The Decanter comes in front-loading, rear-loading, or self-dumping configurations in order to match existing plant operations.

Q. What are the advantages of the Decanter dewatering system?

The Decanter provides the dewatering performance required to effectively dewater fine grit particles captured by Hydro International’s high performance grit removal system in smaller plants. A wedgewire screen allows the water to drain from the captured grit without being lost with the effluent water. Durable galvanized construction provides a long product life. The Decanter is a cost-effective solution for small plants unwilling to sacrifice performance. Multiple Decanter units can be used to increase dewatering capacity or to facilitate disposal operations.

Q. When should we select a Eutek Grit Snail^®, and when should we select a Decanter dewatering system?

As a general rule of thumb, larger plants will typically require a Eutek Grit Snail^® system. In many smaller plants, a Decanter system will provide cost-effective dewatering performance. Contact Hydro International to determine whether a Eutek Grit Snail^® or a Decanter dewatering system is the optimal choice for your plant.
