Basket Strainers: How to Use Them to Improve Your Process

Flow Control Network

<<Whether the flowing material is seawater, oil, paint or a variety of food or chemical products, there is often something present that can cause trouble. Dirt, foreign matter or even clumps of the product itself can clog or damage pumps, spray nozzles, condensers and similar equipment. Sometimes a finished product has to be rejected because of the presence of undesirable solid matter. Basket strainers remove unwanted particles from pipeline flow.>>

<<When it comes to solid-liquid separation, plant engineers and process engineers have a variety of options to choose from: horizontal-plate filters, vertical- and horizontal-plate filters, Nutsche filters , self-cleaning filters.>>

Engineering Aspects in Solid-Liquid Separation

by Josh Halberthal

<<Solid-Liquid Separation is a major unit operation that exists in almost every flowscheme related to the chemical process industries, ore beneficiation, pharmaceutics, food or water and waste treatment. The separation techniques are very diverse and the objective of this site is to provide a platform for plant and design engineers, research personnel and students to discuss practices, experiences and new developments in this fascinating unit operation.>>

Piping for Sand Filter Systems

Mer-Made Filter, Inc.

<<The piping arrangements possible when using sand filters are extremely flexible. This can be very helpful when laying out a new or retrofit system since the influent, effluent and backwash connections can be configured to match the way the pipes come from and return to the pool.>>

The Design of Process Filtration Systems

Engineer's Digest

<<Single-pass filtration systems are those in which process fluids pass through the system only once and are not recirculated. The major objective in single-pass systems is the reduction of contamination. However, other objectives might include clarification or classification. Clarification entails reducing the effects of particles on fluid clarity. Classification is the removing of selected particle sizes while intentionally leaving others. Filtration system design or an upgrade consists of two phases. First, filter locations are determined, and the media that will be used in them are chosen. Then, actual filter assemblies are selected based on manufacturers' published data.>>

Pipeline Strainer Installation Considerations

Hayward Industrial Products, Inc.

<<Strainers are bolted, screwed, or welded into pipelines like valves. In fact, because of the similarity in materials of construction, pressure ratings, etc., a strainer is installed in the same way as many valves. There are two fundamental types of pipeline strainers- Basket and Y-Type. Generally, Y-strainers are used with gases and in cases where the necessity for cleaning is infrequent. Basket strainers are generally used with liquids and where regular or frequent cleaning is needed. Basket strainers hold considerably more material than Y-strainers and they offer less pressure drop than Y-strainers - both factors of more importance in liquid flow than in gaseous flow.>>

What Is Reverse Osmosis?

Osmonics

<<Reverse osmosis, also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as ions from a solution. Reverse osmosis is used to purify water and remove salts and other impurities in order to improve the color, taste or properties of the fluid. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing. The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications that are currently in place.>>

Nanofiltration Technical Papers

Osmonics

<<Nanofiltration is a form of filtration that uses membranes to preferentially separate different fluids or ions. Nanofiltration is not as fine a filtration process as reverse osmosis, but it also does not require the same energy to perform the separation. Nanofiltration also uses a membrane that is partially permeable to perform the separation, but the membrane's pores are typically much larger than the membrane pores that are used in reverse osmosis.>>

Ultrafiltration Technical Papers

Osmonics

<<Ultrafiltration is a form of filtration that uses membranes to preferentially separate different fluids or ions. Ultrafiltration is not as fine a filtration process as nanofiltration, but it also does not require the same energy to perform the separation. Ultrafiltration also uses a membrane that is partially permeable to perform the separation, but the membrane's pores are typically much larger than the membrane pores that are used in nanofiltration.>>

Microfiltration Technical Papers

Osmonics

<<Microfiltration is a form of filtration that has two common forms. One form is crossflow separation. In crossflow separation, a fluid stream runs parallel to a membrane. There is a pressure differential across the membrane. This causes some of the fluid to pass through the membrane, while the remainder continues across the membrane, cleaning it. The other form of filtration is called dead-end filtration or perpendicular filtration. In dead-end filtration, all of the fluid passes through the membrane, and all of the particles that cannot fit through the pores of the membrane are stopped.>>

Microfiltration of Ultrapure Fluid

Osmonics

<<Microfilters are employed as polishing filters in the pharmaceutical, electronics, and specialty chemical industries. Electronics and pharmaceutical companies use microfiltration for polishing ultrapure water. Specialty chemical companies use filters to remove impurities after processing. Osmonics® offers a wide variety of nominal and absolute rated pleated filters to match the needs of all of these industries.>>
