For some international and large readymix companies, they need clean water as well as aggregates, and it is not allowed to reuse the slurry water in the batching plant. Introducing from Australia technology, UDO designs and develops the filter press system in order to solve the treatment of slurry water. Dry cakes and normal clean water can be recycled through this system which realize “Zero Waste”, “Zero Discharge” and make the batching plant green.
1. All the filter plates are made of totally new polypropylene.
2. The water is clean and the mud cake has low moisture content.
3. The filter press has an automatic flap device.
4. The filter mud is unloaded by a plate pulling trolley.
5. An electric three-way valve is installed by the water channel. When working normally, the clean water is discharged into the clear water tank. When the filter cloth is cleaned or the water is discharged abnormally, the valve is used to discharge the slurry water into the slurry tank to ensure that the slurry does not flow into the clean water tank.
6. Large amount of discharged water（High pressure type）
A filter press is a device used for separating solids from liquids. It is a piece of equipment that is commonly used in various industries such as pharmaceuticals, food and beverage, chemical manufacturing, and wastewater treatment plants.
The basic design of a filter press consists of a series of plates with filter media, such as cloth or paper, that are arranged in a vertical stack. The plates are pressed together using a hydraulic or mechanical mechanism, which creates a sealed chamber between them.
The process begins by feeding a slurry, or a mixture of solids and liquids, into the filter press. The liquid portion of the slurry passes through the filter media and is collected in a collection tank or reservoir. The solid portion of the slurry, or the filter cake, is retained on the filter media and is removed from the filter press.
The filter cake is then washed with additional water or other cleaning solutions to remove any remaining liquid or impurities. The washing process can be repeated multiple times to ensure complete removal of all solids.
Once the washing process is complete, the plates are separated, and the filter cake is removed from the filter press. The plates are then ready to be used again for the next filtration cycle.
The four main components of a filter press are:
Filter Plates: The filter plates are the primary components of the filter press. They provide the surface area where the filtration takes place. The filter plates are typically made of plastic, metal, or other durable materials, and are covered with filter media such as cloth or paper.
Hydraulic System: The hydraulic system provides the pressure necessary to compress the filter plates and create the sealed chamber where the filtration takes place. The hydraulic system typically consists of a motor, pump, and hydraulic fluid reservoir.
Filtration Pump: The filtration pump is used to feed the slurry into the filter press. The pump must be capable of handling the specific characteristics of the slurry, such as its viscosity and solids content.
Control System: The control system is responsible for regulating the operation of the filter press. It typically includes various sensors and gauges to monitor the pressure, flow rate, and other critical parameters. The control system can be automated or manual, depending on the specific application and user preferences.
1. Drive the truck to the fixed place, start the button switch, and the water pump will fill the water into the mixing trucks automatically.
2. Dump the waste concrete into the hopper, then through the reclaimer, the sand and stones will be separated cleanly from two different outlets.
3. The slurry water overflows to 2 mixing tanks, and there’re agitators to prevent from settling. Through the water sensors and pumps, the slurry water will be pumped into the filter press, and through the filter press system, it will get clean water and sludge cakes.
4. The clean water could be reused in batching plant or wash truck mixers, and the left could be discharged through the PH control system. And the sludge cakes could be reused to produce bricks and blocks.
