The invention of Seitz filter sheets at the beginning of the 19th century and the market introduction of the Seitz-EK by Theobald Friedrich and Georg Seitz can be regarded as a milestone in beverage production. Back then, the use of Seitz-EK filter sheets allowed for the first time the "cold-sterile" bottling of beverages without the necessity of heat treatment and without noteworthy quality losses.

Obviously, this invention can be considered as one of the most important pioneering achievements for the beverage industry.

Seitz FA-Series Developed to meet the production needs and requirements of the fruit juice industry and associated applications requiring TAB spores control. Seitz HS Series Depth Filter Sheets Developed to meet the production needs and requirements of the food and beverage industry for various products such as beer, gelatin or enzymes.

The high stability of Seitz HS sheets enables long production runs of aqueous and higher viscous fluids at low and high temperatures. These filter sheets are characterised by an increased chemical and mechanical stability. They are particularly suitable for the filtration of aggressive media. An outstanding property of the HR-sheets is their high resistance to cellulose-degrading enzymes.

They are characterized by a coarse pore structure and combine high throughput with a high particle holding capacity. The filtration resistance is low so that they prove to be very successful for the filtration of viscous media and for the retention of gel particles or coarse disperse components.

Sheets are acid washed for reduced Calcium and Magnesium contents. Seitz IR Series Depth Filter Sheets Undergo a proprietary treatment that results in extremely low levels of extractable ions making them the ideal solution for distilled spirits applications. A visually bright finished product free from visible particles is one of the main objectives of spirits filtration. Magnesium may also cause precipitations in tannin containing spirits like whisky and brandy. Standard filter sheets contain small quantities of these extractable ions from the raw materials.

Pure Cellulose Sheet Media Consists of highly fibrillated pure cellulose produced without the use of any inorganic material such as DE or Perlite.

A Guide To The Google Sheets Filter Function

You can use this Google Sheets tutorial as a reference guide to Filter. Once you complete this tutorial, start using this function offer with sample datasets. I am sure that you will slowly become a pro in Google Sheets Filter.

You can conditionally filter a source range to get only the required information. By doing so, you can exclude unwanted Rows and Columns from the output. Let me explain the Filter function arguments first. After that, we can move to some basic examples.

Quite confusing right? The below formula can clarify your doubts. One more thing. In independent use, this formula must be entered as an ArrayFormula like. You may have noticed the formula in cell E2. As you can see, the formula returns an array result. See the below formula where the condition is in the range C2 :C21which is outside of the filter range of A2 :B The below formula is also based on the same above sample data.

In this Filter formula, I have used the conditions from two different columns. Here in Filter, the approach is straightforward. You can directly use the cell references inside the formula.

The easiest way to apply multiple conditions in a single column equivalent to OR is using the Regexmatch in the Filter condition as below. This means you can use other functions as conditions in Filter. But there are enough solutions.

You can use the functions SearchFind or Regexmatch as below as an alternative to Wildcards in Filter formula. The first formula is case insensitive and the other two are case sensitive. With this example, I am winding up this tutorial on how to use the filter function in Google Sheets.

I hope you may know that the value of the toggled tick box is TRUE. So the entire row that matching the conditions will be populated. The Same is Possible in Query too. For the latest updates please follow me on my social channels. Thanks for the stay! As usually, you have crashed the topic. However, I cannot find the solution for something more complex. You have two tables:. I would like to retrieve all purchases from table 1 but starting from a date that is displayed in table 2.Ensure the appropriate seals are fitted to each filter plate.

Different makes and grades of filter sheet vary in thickness, so it's possible that seals of a different thickness may be needed; this normally only applies to 20 x 20 cm filters where 3.

A filter sheet should be inserted carefully centrally between each of the filter plates. The smooth side of the sheet is the discharge side. Seitz and Beco sheets are printed on the smooth side. Cordenons sheets are printed on the coarse side. There may be an even or odd number of filter plates, according to the model of filter and whether a single or double filtration with changeover plates is being carried out. When all the sheets and plates have been inserted the centre-screw-spindle is screwed in just enough to hold the 'filter pack' sufficiently firmly to stop the sheets slipping.

Water is then poured over the filter pack to thoroughly moisten the edges of the sheets. Not all types of filter plates are suitable for steaming. Noryl black plastic is a suitable material, even better is stainless steel.

The inlet of the filter is normally the lower connection point. Bringing the steam in from the lower channels inlet side could have the effect of washing off and thereby damaging sheets on the feed side. The bottle filler and connecting tubing must also be steam sterilised, by connecting to the inlet of the filter.

The nozzles of each filling tube must be propped open to allow steam to flow freely from them. The condensation water accumulating in the filter should be allowed to drain off freely at the bottom, by having the drain taps slightly open. It is important that each side-branch in the filter pressure gauge etc has a drain-cock through which steam can flow during sterilisation. The thermal load during sterilisation somewhat reduces the strength of the filter sheet.

The steaming process must be carried out with the filter pack slightly loose. This not only provides space for thermal expansion but allows the free flow of condensation water in the area of the sealing edges. All valves must be slightly open initially during the steaming process, and steam must flow for at least 20 minutes after it starts to flow out of the filler tubes. The rinsing process must be carried out with the filter pack slightly loose, to allow some free flow of water in the area of the sealing edges.

If this is not done, sludge particles deposited during filtration can be squeezed through the filter sheet with escaping gas bubbles.

Procedure: use appropriate tubing to connect the pump inlet to a vat of clean water, the pump outlet to the filter inlet, and the filter outlet back to the vat of water with the tube carefully positioned so that the bubbles do not circulate back to the inlet; direct the tube inside a jug placed under the water.

Adjust the pump bypass until the flow is as specified above, continue circulating for at least 10 minutes until the sheets are saturated with water and all air has been vented, then for a further 5 minutes with the outlet going to waste. Food-grade grease or Vaseline must be applied to the screw thread in order to prevent wear and make it easier to turn.

Before stopping the pump always open the pump bypass so that the pressure is low. The pump inlet should now be connected to the tank of wine to be filtered. Start the pump and begin to filter slowly.The Google Sheets Filter function is a powerful function we can use to filter our data.

The Google Sheets Filter function will take your dataset and return i. Suppose we want to retrieve all values above a certain threshold? Or values that were greater than average? Or all even, or odd, values? In this example, we have a range of values in column A and we want to extract specific values from that range, for example the numbers that are greater than average, or only the even numbers. The filter formula will return only the values that satisfy the conditions we set.

The syntax is:. For example, using the basic data above, we could display all the values i. Yes, simply add them as additional criteria to test.

For example in the following image there are two columns of exam scores. The Filter function used returns all the rows where the score is over 50 in both columns:. Note, using the Filter function with multiple columns like this demonstrates how to use AND logic with the Filter function.

Instead of hard-coding a value in the criteria, you can simply reference another cell which contains the test criteria. That way you can easily change the test criteria or use other parts of your spreadsheet analysis to drive the Filter function.

For example, in this image the Filter function looks to cell E1 for the test criteria, in this case 70, and returns all the values that exceed that score, i.

Advanced Filter Examples in Google Sheets. Do you know if there is a way to return the values horizontally instead of vertically? For example if there were 4 results and the formula was in cell B2 then the results would be in B2, B3, B4, B5.

Is there a way to instead have the results return in cells B2, C2, D2, E2? Hi there, what would be the best way to do this in google sheets…make a list of students who have a score of 0 for at least one assignment.

However, you may find it difficult to achieve a leak free seal. The cell body o-rings necessarily compress the membrane during installation and the physical action of separating the membrane from the o-rings during removal may cause damage.

This damage can impede that ability to achieve a leak free seal when the membrane is reused. Used flat sheet membranes must always remain wet, including during storage. Membranes that are allowed to dry will irreversibly loose water permeability. To prevent microbial growth, the membranes can be stored in a 0. Alternatively, the membranes can be stored in a 1. To maintain efficacy, the SMBS solution should be replaced monthly.

Or the membranes can be stored in UPDI water that is replaced weekly. Unfortunately, allowing a previously wetted crossflow membrane to dry usually results in permanent reduction of water permeability.
