Decanter Solutions:


What is a Decanter Centrifuge?

Horizontal Bowl centrifuges are also known as decanter centrifuges, centrifugal decanters or simply decanter machines and are primarily used for separation of liquids from appreciable amounts of solids. Decanters can separate over 50% (v/v) solids from liquids on a continuous basis. Typical industrial decanter applications include Crude Oil Tank Bottoms; Waste Oil; Industrial Wastewater; Sludge Dewatering; Fish Meal; WVO/UVO De-Sludging; Paint Sludge; Rendering etc. etc.

How does it work?

A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required.

The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually "ploughed" out of the pond and up the conical "beach". The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl.

Centrifuge Filtration-Clarification Systems

Manual Clean & Automatic Self-Cleaning Liquid/Liquid/Solids Centrifugal Separators:

Fluid is continuously pumped to a centrifuge filtration-clarification system where it is then subjected to high G forces. The fluid typically separates into a heavy phase (water) and a light phase (oil). The two liquid phases separate and the liquids exit the centrifuge through separate liquid discharge connections. Residual solids are separated and removed manually from manual clean units or discharged automatically (with an automatic self-cleaning style unit). These units are supplied with all stainless steel bowl components, necessary bowl insertion tools, set of gravity discs, supply device with sight glass for priming and wash water, outlet sight glass, revolution counter, standard set of tools, dual voltage electric motor, vibration isolators, mounting base, and operation manual.

All machines can be supplied as skid modules with custom control pumps, heaters, tanks, and other accessories. Complete custom solutions are also available.

DAF: Sludge Dewatering Systems

Proper sludge disposal and treatment enable operators to dramatically reduce disposal costs and improve the recovery of valuable oil and clean water. Sludge applications utilize decanter centrifuge and centrifuge filtration-clarification systems to properly separate and treat sludge from liquid processes.

Advantages
• Reduces total disposal volume by as much as 70%
• Produces stackable cake-like sludge
• Reduces handling costs
• Increases options for sludge disposal

The centrifuge is an effective piece of equipment for dewatering solids skimmed off most Dissolved Air Flotation (DAF) wastewater systems. The skimmed solids are typically wet, sloppy, and expensive to handle. Hard Chrome Solutions offers a wide range of liquid-liquid and liquid-solid centrifuge separation, solids dewatering, and centrifuge liquid filtration and fluid clarification systems and process options to optimize the advantages of the DAF Sludge Dewatering System.

Municipal Wastewater Treatment Systems:

Municipalities focus on water conservation center on advanced wastewater treatment. Sewage sludge volume is on the increase, and in order for municipalities to solve the problem they seek out our durable, reliable and cost-effective centrifuge systems. Decanter centrifuges are used extensively in sludge thickening and sludge dewatering duties.

Wastewater treatment plants for both municipal and industrial applications are designed to produce a clean, safe water discharge, usually to a river. The complexity of the plant will depend on the immediate environmental considerations and the consent limits negotiated with local, state and federal authorities.

Water Wash Spray Booth Paint Sludge Recovery:

Water wash paint booths face constant sludge recovery problems, especially when production volumes increase. In high volume environments, the equipment used to recover sludge from paint booths simply can't keep up with production volume. Centrifuge sludge-recovery systems facilitate separation while dramatically reducing labor costs, water consumption and chemical use.

Many water wash paint booths employ specialized equipment to recover sludge. Water wash paint booth operators who don't use centrifuges typically experience problems with traditional and ineffective paint separation methods, such as:

• Frequent maintenance down time associated with paint sludge
• Extra working shifts for cleaning
• Extra working shifts to make up production for booth downtime
• High cost of contaminated booth water
• High cost of wet sludge removal and disposal

Efficiently moving paint solids to the point of extraction for separation and removal requires specialized equipment, knowledge and experience. Hard Chrome Solutions engineers and technical support staff have the specialized expertise to design and install a complete paint sludge recovery system for new and existing paint installations. Centrifugal separation equipment can be designed to fit any paint wastewater treatment applications, from a single water wash booth to larger operations with multiple booth bays. By correctly integrating booth design with the paint sludge system it is possible to enhance booth efficiency and drastically reduce downtime and maintenance.

Hard Chrome Solutions designs modular dehydration and water clarifying systems for efficient settling and collection of suspended solids for the glass, stone, and other brittle material fabrication industries. Our engineers design and build settling tanks that have two specially baffled cone bottom tanks of specific volume with a drain manifold, valves and bags that hang to collect concentrated slurry, which are easily removed for replacement and disposal.

Settling Tank Features and Advantages
• Large water volume for added retention and greater settling time
• Large water volume stored above bags provides greater static drainage pressure
• Heavy-duty poly tanks with structural steel support base for added quality and long term usage with six bag drain manifold per tank
• Six smaller bags provide greater total external bag surface area for improved drainage capability and improved solids dehydration to the center of the bag
• Up to 50-lbs sludge cake per bag provides easier "one-man" handling and do not require added material handling equipment for exchange
• Fully engineered pre-constructed system modules ship knocked down for easier handling and sets up quickly for easy installation
