Filterpress

Filter Press

A filter press is commonly used in three applications: as a fixed volume, batch pressure filter; as a polishing filter to remove solids from a stream; and as a variable volume filter through a filter plate.

Filter press is a separation process, specially employed by solid/liquid separation using the principle of pressure drive, provided by a slurry pump. Filter press is a fixed volume and batch operation, which simply means that the operation must be stopped to discharge the filter cake before the next batch can be started. The major components of filter press are skeleton and filter pack. The skeleton holds the filter pack together while pressure is being developed inside filter chamber. It however can only hold a specific volume of solids.

In operation, slurry is pumped under pressure into the press chambers through the manifold at the stationary head of the filter press. As each chamber fills with slurry, the liquid passes through the cloth medium, across the drain-field, through the drain ports and exits via gravity out of the corner discharge eyes.

The prime function of the filter media is to provide a porous support structure for the filter cake as it develops and builds. Initially, some solids may pass through the cloth media causing a slight turbidity in the filtrate, but gradually the larger particles within the slurry begin to bridge the openings in the media reducing the effective opening size. This allows smaller particles to bridge these reduced openings initiating the cake filtration process. Once a layer of solid particles achieves 1 to 2 mm in thickness, this “precoat” layer serves to separate out finer and finer particles as the cake builds in thickness, yielding a filtrate that is very low in turbidity.

Maintaining a clean environment, production of food and beverages, and development of essential medicines require filters that separate solids from liquids. ANDRITZ offers filter presses for a wide variety of applications and industries, ranging from treatment of wastewater sludge and drinking water, the food and beverage industry, the chemical industry, pharmacy and mining, to paper production. Applications include:

  • chemicals and pigments
  • metallurgical products and ores
  • minerals and inorganic products/mining
  • industrial and municipal wastewater treatment
  • food and pharmaceuticals

Belt Filter

The belt filter  is an industrial machine, used for solid/liquid separation processes, particularly the dewatering of sludges in the chemical industry, mining and water treatment.

The belt filter is mainly used for dewatering of sludge and slurry. Belt filters are used both municipally and industrially in a range of areas including urban sewage and wastewater treatment, metallurgy and mining, steel plants, coal plants, breweries, dyeing, tanneries, as well as chemical and paper factories. The applications of a belt filter are only limited to the sludges, slurry. The sludges from municipal use include raw, anaerobically digested and aerobically digested sludges, alum sludge, lime softening sludge and river water silt. In industry, any sludge or slurry is sourced from food processing wastes, pulp and paper wastes, chemical sludges, pharmaceutical wastes, industrial waste processing sludges, and petrochemical wastes. These wastes can include mixed sludge, mineral slurry, dust sediment, selected coal washing mud, biological sludge, primary sludge, and straw, wood or waste paper pulp. Some dewatering objectives include reducing the volume to reduce the transport and storage costs, removing liquids before landfill disposal, reducing fuel requirements before further drying or incineration, producing adequate material for composting, avoiding runoff and pooling when used for land applications, and optimizing other drying processes. Belt filters are specifically designed for each of these particular applications and feeds
There are many physical separation processes similar to the belt filter used for dewatering, including centrifuges, vacuum-disc filters, and the plate and frame filter press. When compared to other compression filters, belt filters use relatively lower pressures. Although centrifuges have lower moisture content, lower costs and simpler operations in coal tails processing, belt filters tend to make less noise and have much quicker startup and shutdown times. Belt filters are considered simple and reliable, with good availability, low staffing, easy maintenance and a long life. The belt filter is most advantageous when installed such that it is open and viewable at floor level for easier adjustment and monitoring. This is of course subject to what lighting and ventilation will allow. The belt filter press is often used in wastewater treatment, and thus the odour of the feed sludge, volatile emissions and the chemicals used in treatment, may become a problem. One control method is to use odour-neutralizing chemicals such as potassium permanganate. However this only neutralizes odours and doesn’t affect any gases or chemicals involved. Although all problems can be controlled by enclosing the filter, the enclosure reduces essential visibility and easy access to the machine for maintenance and repairs, leading to the expensive automation of the process. A belt filter press is also known for its high capacity throughput, as it is designed to handle excess capacity. It has low initial costs and low energy running costs.
Belt filters are less effective at processing some feeds. Unless the feed is well mixed from a digester, the use of belt filters will be more costly when processing a feed with varying solids content as this requires more operator attention, raising staffing costs. Feeds with high grease and oil content can lower the solids percentage in the cake by blinding the belt filter and all feeds need to be screened to protect the belt from being damaged by sharp objects. The type of feed may also affect the washing process. The belt filter needs to be washed frequently which consumes large amount of water and time. Water and time wastage, as well as the associated costs can be reduced by automating the washing system and using effluents.

RO System

10 Gal Ro System

 

10 Gal Ro System is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean delicious drinking water.

Series EPC10GalR1 Reverse Osmosis (RO) Systems are commercial grade high pressure RO units for the reduction of total dissolved solids from water. They are designed to supply reverse osmosis quality water with production rates of 10 gallons per minute. These units are designed for floor mount installations. Reverse osmosis is a process where high pressure feed water is fed into a semi-permeable membrane. In the membrane, pure water is allowed to pass through the membrane material and exit as purified permeate water. Dissolved mineral salts are not allowed to pass through the membrane and become a concentrated reject stream that is sent to drain. These RO systems use high pressure/high rejection membranes to achieve a minimum average NaCl ionic rejection of 97 percent.

  • Powder coated carbon steel support frame (We can also Customize the Frame to your factory floor) – Optional
  • Corrosion resistant 300psi FRP high pressure membrane housings
  • Pressure gauges for pre-filter inlet/outlet, membrane feed, and reject water pressure
  • Low feed water pressure safety switch
  • Digital microprocessor based controller with delayed auto restart after low pressure shut down
  • Permeate water conductivity meter with high conductivity alarm output
  • Tank level and pretreatment interlock inputs
  • High pressure/high rejection membranes with 97% minimum average salt rejection
  • Permeate, reject recycle, and reject water flow meters
  • Adjustable reject and reject recycle valves
  • Permeate check valve
  • Automatic inlet diaphragm valve
