Rotary drum screen--A key to successful wastewater filtration

 The rotary drum screen or rotary filter screen is part of the equipment usually found in municipal and industrial water treatment processes. This is the second pre-treatment process used in wastewater treatment plants after screening. It is generally placed upstream of the system, i.e. at the discharge of the pumping station which is in charge of collecting the wastewater to remove suspended solids from raw wastewater.

In addition, the sifter can collect mechanically fine and coarse debris. This way, the waste will not be mixed with mud and will not interfere with the downstream process.

The purpose of the rotary drum filter screen is to sort out various fine and coarse matters. The rotary drum screen ensures a fine screening based on the mesh size. 

 

Basically, all rotary drum screens have similar features:
Compactness
Easy to operate
Screening: a rotary drum screen use for solid/liquid separation. The finer the mesh, the more effective the separation. 
Securing the downstream process

Such as the Solid/liquid separation for the food industry:
meat processing factories
slaughterhouses
dairies
fast food
Viticultural and vinicultural effluents,
fish industry
potato processing
canning factories
animal feeding

Or in many activities:
Wastewater pretreatment for municipal and industrial wastewater
Storm overflow collection
Wastewater treatment with high content of solids including fibers, wool, feathers, and films.
Effluents from paper mills
The textile industry like dyeing, bleaching, etc…
The chemical and pharmaceutical industry

Screening and rotary drum screen is a very good idea to test its efficiency on your process.

Crude Prefiltration with Sieve Bend Filter Screen

 The sieve bend screen – also called bend screen – comprises a curved screen for filtration. The bend screen provides filtration by guiding the particles along with the curved sieve filter screen.

In some horticultural growing systems applying recirculation, large volumes of rainwater are produced. Particles and fibers flush with the drain water from for example tray- and container fields in strawberry and ornamental horticulture as these crops are still grown on peat or coir. Before collecting the water in a filthy drain silo it is necessary to remove these particles.

A sieve bend screen filter can be placed on top of a silo and separates the floating organic material from the drain water. Without this filtration step, the silo would pollute quickly.


Sieve bend screen filters are made in several shapes and sizes.  We are able to manufacture using different kinds of materials and grades depending on your request. Also, special surface treatments are available for your application of the wedge wire screen.

We are capable of manufacturing sieve wedge wire screens in customized dimensions, radii and lengths with skilled engineering and precise production.

Stainless Steel Perforated Filter Element

 

Stainless Steel Perforated Filter Elements – Perfect Filter Precision and Strength

Perforated filter elements are made of stainless steel. With accurate filter precision and high anti-corrosion performance, perforated filter elements can filter solid, liquid, gas, and others. They are widely applied to rubber, plastic industry, sewage treatment, petroleum, chemical industry, machinery, ships, vehicle industry, food making, and where the possibility of needing to filter accurately.

Generally, perforated filter elements can be divided into six types according to shape:
Cylinder perforated filter elements.
Cone perforated filter elements.
Basket perforated filter elements.
Y-type perforated filter elements.
Sintered and specially shaped perforated filter elements.


Our wire mesh stainless steel filters are useful in a wide range of applications that require a variety of openings. These stainless mesh filters can be used in conjunction with perforated metal filters. Stainless wire mesh filters are ideal for filtration used in adverse environmental conditions, such as jet engine lubricant filters or high-pressure hydraulic filters.

Stainless wire mesh is durable, cleanable, and reusable making it an economical choice for most filtering projects.

Stainless steel filters are available in many configurations. Stainless mesh is very pliable, allowing it to be worked into the custom shapes that are required by our customers. Please contact us to get more information or leave a message to us directly.
