Treatment of surface finishing wastewater
Water Centrifugal Machines
Our Products for Water Treatment
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.
Wastewater Treatment Machines
Filter cloth filtration machines for the treatment of wastewater from surface treatment processes. They operate by pressure filtration, retaining solid particles and automatically producing clean water. Available in different sizes depending on flow rate and type of waste, with a treatment capacity of up to 1 tonne per hour and an automatic warning when the filter cake reaches its limit.
Centrifugal Wastewater Treatment Machine
Particle and liquid separation system using high-speed centrifugation of wastewater from surface treatment processes. Especially effective with oily waste, it avoids the common problems of conventional filtration systems. It operates fully automatically and can treat up to 300 litres of wastewater per hour, producing clean water at the outlet.
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.
