A water centrifuge machine is a device designed to separate solids from liquids by means of the centrifugal force generated by the rotation of a drum or basket. These machines are commonly used in industrial and water treatment applications for the separation and removal of solid particles suspended in water.

It is a technology that ensures the separation of particles and liquids by transferring the wastewater from the surface treatment machines to a boiler that rotates at high speed.

A major advantage over other systems is that oily debris, which causes problems in filtration systems, does not cause problems in water centrifuges.

Our water centrifuges can separate 300 liters of wastewater per hour. They are machines that operate automatically from the inlet of the wastewater to the outlet of the clean water.

The drum or basket is usually equipped with orifices or filters that allow the liquid to pass through, but retain larger solid particles. As solid particles accumulate on the drum walls, they can be periodically removed by controlled discharge.

  • Engine speed: 3000 rpm
  • G-force: 1500 gr
  • Maximum water flow rate: 600 Liters/hour
  • Weight: 560 Kg

Operation of a water centrifuge

The basic operation of a water centrifugal machine involves water or other liquid being fed into the moving drum or basket. As the drum rotates rapidly, centrifugal force pushes the solid particles towards the drum walls, while the cleaner liquid moves towards the center and heads towards the outlet.

These are the main stages in the treatment of liquid waste by means of a centrifugal machine.

    • The first step is to collect the waste liquids generated in the surface finishing process, which may contain solid particles such as paint residues, coatings, powders, metal chips, among others. These liquids are introduced into the centrifuge machine.
    • Once inside the centrifugal machine, the drum or basket containing the waste liquids begins to rotate at high speed. The rotation generates a centrifugal force that pushes the solid particles towards the drum walls.
    • Centrifugal force causes the heavier solid particles to accumulate on the drum walls, while the cleaner liquid moves towards the center of the drum, thus resulting in the separation of solids and liquids.
    • To remove accumulated solids, the centrifugal machine is equipped with holes or filters in the drum walls. These allow solids to be ejected out of the drum into a suitable container or collection system.
    • The clean liquid, free of most solids, is directed to the outlet of the centrifuge machine and can be collected for further treatment, reuse or proper disposal according to requirements.

It is important to note that although water centrifuge machines are an effective technology for the separation and removal of solids in liquid waste, they may not be sufficient to obtain water that complies with applicable environmental regulations.

In this sense, water centrifuges are an ideal technology to be part of a complete water treatment system, as other systems or additional processes may be required to achieve a complete treatment in order to comply with current environmental regulations.

This may include finer filtration systems, decantation, chemical neutralization or other specific treatment methods depending on the characteristics of the waste generated.

Water centrifuges for the treatment of wastewater from surface finishing processes

Water centrifuges are used in the treatment of wastewater generated in the finishing of metal surfaces and parts to separate and remove suspended solids in the water.

A wastewater treatment process using a water centrifuge machine includes the following stages:

    • First, the wastewater generated during the surface finishing process and metal parts is collected. These waters may contain solid particles, treatment chemicals, oils, grease and other contaminants.
    • In some cases, wastewater pretreatment may be required to remove larger or heavier contaminants prior to introducing the water into the centrifuge. This may include screening, sedimentation or other methods of removing larger solids.
    • After this pre-treatment stage, the wastewater is fed into the water centrifuge machine. Depending on the size and design of the centrifuge, a basket, drum or specialized rotor may be used to retain suspended solids while the water is separated.
    • At this point, the separation process is initiated by centrifugal force. The water centrifuge is put into operation and starts spinning at high speed. The centrifugal force generated pushes the solid particles towards the walls of the drum or basket, while the cleaner water moves towards the center and is directed towards the outlet.
    • The solids accumulated on the walls of the drum or basket are periodically discharged. This can be by opening a controlled discharge valve that allows solids to be expelled out of the centrifuge into a suitable container or collection system.
    • Recovery of treated water. The treated water, with a significant reduction of suspended solids, is collected from the centrifuge outlet. Depending on the quality of the treated water and specific requirements, additional treatment may be required prior to reuse or discharge to the wastewater system.

As mentioned above, it is important to keep in mind that the use of water centrifuges in the treatment of wastewater generated in the finishing of metal surfaces and parts is one component of a larger water treatment system. Other processes, such as filtration, decanting, pH adjustment or disinfection may be necessary to achieve complete treatment and comply with applicable environmental regulations.
