What you need to know about a Filter Press

Filter Press

What is a filter press?

This is a tool, which is commonly used in industries like mining in separation processes. To be specific, it is used in the separation of solid and liquid – a slurry pump provides the necessary pressure. The mechanism involved in the use of filter press is fixed volume and of batch operations. By batch operations, it is meant that a fixed volume of mix is put in the press which separates the liquid and the solid and discharges the filter cake. Only after this batch has been discharged can the next batch be started.

What are the components of filter press?

A filter press has two components, which are the filter pack and the skeleton. The skeleton is the outside structure which holds the filter pack together. There is a filtration chamber in the filter pack in which the pressure develops for the separation process. As it is a fixed volume tool, the chamber is able to hold only specific volumes of solids.

What are the common applications of filter press?

The various uses of filter press range from blood plasma purification to dewatering of mineral mining slurries. Specifically in ultrafine coal dewatering, filter press is popular for filtrate recovery in coal preparation plants. This tool is known to be the most reliable and effective technique in metallurgy plant operations. Pilot scale plate filter press is a famous example for good use of filter press in dewatering coal slurries. It is also seen that with the use of filter press, the quality of water recovered in quite improved. This water is generally used for equipment cleaning.

Also filter press is used for municipal waste sludge dewatering- for these primarily automatic membrane filter presses are used. The other uses include metal concentrate recovery, ready mix concrete water recovery and large scale fly ash pond dewatering.

Sugaring operations make use of filter press in processes like production of maple syrup and others – essentially used in raw syrup filtration process. 

Planning or Updating a Garden

Composite Decking Australia

Living amidst natural surroundings is a blessing and if you have a yard, it is worthwhile to transform it into a beautiful garden.

Before you start planting in the garden, it is important to consider hedges to make boundaries, which are useful in protecting the area. This inexpensive ‘fence’ lends privacy and is useful in segregating the garden into various compartments which can be linked by patio or paths. You can choose from a wide variety of privet, formal yew, rustic hawthorn, beech and box or holly. Remember to have a good soil preparation as with hedging plants have to be planted very close and thus require special care.

You can also plant trees on either side of the path at regular intervals - this will make it look very appealing. It is also recommended to have garden focal points. These can be man-made and the options include an urn, a statue or you can even clip and shape the plants or trees and shrubs to look like a seat, a specific shape or a container. Also nicely coloured pots can be placed around the garden to enhance the aesthetics. Small trees in form of bonsais and shrubs look very nice in pots.

To create patios and walking paths in their garden, many people use composite decking in Australia. This is durable and also lends aesthetics to the space.

You can extend the flowering season with the use of roses, tender perennials, bulbs and annuals. To increase the volume, you can plant small shrubs and trees. Flower borders from hardy perennial plants can be utilised to enhance the garden appeal in the mid summers.

Shrubs can add a lot of beauty to the garden. Fragrant shrubs planted in their own beds or as in mixed borders look very pleasing. Also when planted singly in a file, they look very appealing.

Depending on what you would be using the garden for, you can add various elements like a patio or a deck. A patio is very easy to be done and when constructing it, remember that the areas which get most sun are south facing. Also a deck can be easily built quickly.
