Can 300 Micron Mesh Filter Out Algae
When filtering waste vegetable oil or waste matter motor oil, we all typically employ filters that are rated in micron ratings. But, what practice those ratings really mean? And how big is the pigsty? If you oasis't seen or touched an actual micron screen, it's difficult to go a relative size in mind of merely what a particular mesh might look similar.
So, we decided to take some pictures of unlike micron rated stainless steel mesh so y'all could go a feel for things.
Before we start with the pictures it'south important to empathise what the micron rating actually represents.
Microns is a metric measurement that refers to how big the hole is in the weave of wire. It ties to a millimeter square pigsty. For example, a 1000 micron mesh means that each hole is ane mm. A 400 micron weave means that each hole is 0.400 millimeters. A 100 micron weave means that each hole is 0.100 millimeters. Then the smaller the number, the smaller the hole.
Too, before starting, hither'southward the total specs on the mesh we'll be taking pictures of.
Nominal means "average particle size" allowed through the filter
Absolute means "largest particle size" immune through the filter
Evidently Dutch and Twill Dutch carry both a nominal and an absolute micron ratings.
The Straight Weave mesh only carries a nominal micron rating.
And here's what the weave styles mean.
Cheesecloth Equivalents
– Cheesecloth is sold in MESH ratings.
Hither's how to catechumen it to Micron
– 12 Mesh Cheesecloth – 1526 micron Stainless Mesh
– 20 Mesh Cheesecloth – m micron Stainless Mesh
– 30 Mesh Cheesecloth – 600 micron Stainless Mesh
– twoscore Mesh Cheesecloth – 400 micron Stainless Mesh
– 50 Mesh Cheesecloth – 300 micron Stainless Mesh
– 60 Mesh Cheesecloth – 234 micron Stainless Mesh
– 80 Mesh Cheesecloth – 177 micron Stainless Mesh
– 100 Mesh Cheesecloth – 149 Micron Stainless Mesh
Then, with that in mind, let's show some pictures….
The start few pictures are all the samples together.
This shows the broad range of sizes available.
This shows our large hole mesh. 1/4″, 1/8″, and i/16″. The 1/sixteen″ is also known as our 1526 micron mesh too. These are heavy duty meshes with fairly thick wires and big holes.
These are our standard hole meshes. Nice & sturdy with a wide range of hole sizes. 1000 is extremely sturdy and gets used as a capitalist to our smaller meshes quite often. 800 feels like to 1000, simply isn't quite so hard to bend. 600, 500, 400, and 300 are pretty robust and are by far the most popular sizes.
These meshes are the smallest of our standard weave meshes. 234 is commonly used in the marijuana production manufacture while the other sizes are used in just about every production manufacture we work with.
These are our tightest meshes. The 100 and 74 meshes feature a nice, tight plain dutch weave while the 15 and five feature an extremely tight twill dutch weave mesh. The 5 micron is extremely sparse and flexible and requires a backer when used as a filter.
The 177 and 149 micron are semi-transparent. The 100 micron is much tighter. The 74 micron reminds me of a t-shirt weave. The 43 Micron is like a high thread-count bed-sheet. It has an extremely tight weave just as yous feel it, yous can nevertheless somewhat feel the wire threads. The 15 and five micron sheets look and feel but like a sheet of glossy paper. They're extremely malleable and will easily conform to just near anything they're pressed into–particularly the 5 micron! However, this also ways that they tin can have a tendency to tear fairly easily.
Also, here's a video of some of the mesh samples also

We besides shot a video of water flowing through 74, 43, 15, and 5 micron stainless mesh in the form of our Stainless Bucket Filters. It helps give you an idea of what the flow rate of water through the screens would be.

Ok, more pictures!
For these I took close upwards shots of each piece with a penny on them to give you a relative size of the mesh holes. As you look at the pictures, expect at the Fifty in the give-and-take LIBERTY on the penny. It will act as a good approximate to compare confronting any screen you lot may have that you're trying to match.
This reminds me rabbit cage wire. It has 1/4″ holes and is fairly rigid. It makes an excellent strainer for getting really large chunks. Nosotros build a bucket strainer out of this cloth that is well liked by restaurants.
This cloth has pigsty sizes one-half the size of the to a higher place sample at i/viii″. Nosotros've used information technology for a variety of custom filters for filtering large particles out of liquids or even powders. Because the holes are closer together, the material is stronger than the 1/iv″ to a higher place. It makes a great filter!
1526 Micron is our largest mesh that nosotros stock. Information technology's extremely heavy duty and robust. Much bigger than a window screen. It'due south some tough mesh!
This i is 1000 micron. Notice that the Fifty in Lincoln easily tin can fit within each square. This is besides bigger than a typical window screen. This will filter granulated carbohydrate extremely well. It lets sugar fall through it just anything larger than carbohydrate will be held by the filter.
800 micron has pigsty sizes very similar to a typical window screen. Information technology's a adequately rigid material and holds up well to weight in filters.
600 micron is very similar to the rigidity of the 800 micron above just with a smaller hole size. This size is very popular every bit the outset filter for waste vegetable oil or waste material motor oil. In fact, nosotros even use it as the preferred filter with our locking drum lids.
500 micron is only a picayune smaller than 600 micron. Information technology's a pop size for beer mashing and grain brewing. It'south too a dainty size for filtering vegetable oil with every bit well.
400 micron is a pace downward in hole size from the 600 micron and is by far our most pop size for filtering vegetable oil before reacting it into biodiesel. In fact, it's the size I personally utilize when filtering my oil before putting it into my BioPro 190 Automated Biodiesel Processor
If you're looking for a great universal size for vegetable oil filtering, this is the size I e'er recommend.
300 micron is but a hair smaller than 400 micron is and is by far the virtually popular size among beer brewers! In fact, it'due south the #1 size we sell in our brewing filters.
234 micron is a special size nosotros brought in for customers in states where marijuana production is legal. It's the largest size they typically use to filter out the plant media. It's a fairly robust mesh and can be used in just about any application needed.
177 micron has always been popular among our customers filtering waste engine oil and waste matter vegetable oil to be used straight in a diesel engine. It'southward weave is fairly tight and information technology does a adept chore of getting a lot of the gunk out. If your liquid your filtering is thick, information technology can take a while to go through 177, so program accordingly, simply information technology does a great job of filtering!
149 micron is the closest we have to 150 micron. We've had several customers that demand to get as close to 150 equally possible and we've used information technology for a multifariousness of custom filter applications. It was even one of the sizes we offered in our drum filters when we offset released them. It's not a terribly rigid cloth and isn't the greatest for bearing a lot of weight, only if y'all admittedly demand something close to 150, this is it!
120 dutch is great! It's a plain dutch woven mesh, which makes information technology nice and strong, and information technology has a swell hole size just in a higher place the 100 micron dutch below. It'due south a newer mesh to our line of mesh and works great for making a nice, stiff, rigid filter.
100 micron is awesome! Information technology'southward our go-to size for methoxide filters. The pigsty size is perfect for keeping sodium or potassium hydroxide in the filter until the methanol can dissolve it. Information technology has a actually tight weave and it's ane of the toughest stainless mesh sizes nosotros offer. Information technology'southward extremely rigid and holds it'southward shape exceptionally well. In fact, because it's then potent, we're able to build bigger filters out of it without having to add together supports.
74 micron is our smallest size nosotros offer in our standard filters. It'south extremely popular among those filtering waste material vegetable oil and motor oil. It's very good at getting the really small-scale stuff out and is usually the last stainless filter our customers utilise before switching over to our pocketbook filters for smaller sizes. It does take longer than the larger sizes for liquids to filter through it, just it's a good, heavy duty mesh that holds up well over time. This is past far our about preferred size for cold mash coffee brewers. It's been extremely popular with them and holds upwards well.
Nosotros also took some pictures at high magnification to show the mesh even closer.
This blitheness is at 12.5 x magnification (1000 micron to 5 micron).
Here's an blitheness of mesh at 30x magnification (100 micron to v micron)
Here's a picture of 100, 74, 43, 15, and 5 micron at 30x magnification
At present for some perforated stainless!
3/4″ Perforated Stainless Steel. 16 gauge on 1″ centers. We use this as a backer on our large stainless steel filters. It'southward extremely robust
1/2″ Perforated Stainless Steel. 16 gauge on 3/eight″ centers. We also use this to back our big stainless steel filters. It'due south actually tough stuff!
ane/4″ Perforated Stainless Steel on iii/8″ centers. This is a heavy duty 1/4″ perf. We don't use it a lot, but when it's needed it does an awesome task.
one/4″ Perforated stainless steel on 1/viii″ centers. This is 18 gauge and nosotros use information technology all the time to dorsum suction filters and smaller filters with really fine stainless mesh.
1/viii″ Perforated Stainless Steel on 3/xvi″ centers. We employ this to back suction filters and smaller filters equally needed. Information technology tin can also be used to dorsum stainless mesh equally well.
iii/32″ Perforated Stainless Steel on 5/32″ centers. This is xvi approximate 304 stainless steel and is commonly used past brewers every bit a false bottom. It can also be used as a backer with stainless mesh too.
1/16″ Perforated stainless steel on ane/8″ center. We use 18 gauge in this size. Information technology'southward used for really small suction filters or places where one/16″ holes are necessary with a strong structural bankroll.
For the adjacent fix of pictures, I set up a light below a drinking glass plate and ready the mesh onto the plate ane by one to meet what the transparency through the mesh looks similar.
low-cal for transparency exam
I was able to easily see through everything downwardly to 120 micron. 100 micron started to become harder to see through. 74 micron got even tougher, I could make out the faint glow of the bulb, and at different angles I could even make out the outline of the bulb, but it was still pretty opaque. The 43 micron hid the seedling even more and at 15 micron, I wasn't able to run into the seedling at all but could tell something behind it was glowing. five micron made it even more difficult to see the light backside it. You could faintly tell that at that place was a light backside it, but couldn't make out what information technology was at all.
Now the meg dollar question…which one should y'all use? Well, that depends on your awarding.
If you're filtering waste vegetable oil for biodiesel production, I recommend either 600 or 400 micron screens. If you take really thick, nasty oil, 800 would be cracking to apply to get the big chunks out. 400 micron is what I personally use in my own oil filtering setup when I'chiliad planning to make Biodiesel.
If yous're filtering Straight Vegetable Oil or Motor Oil, the 177 and 100 micron are clearly the most popular. The 74 micron will however work, simply yous may exist hanging effectually a while waiting for the oil to period through the mesh. The 40 & xv micron are good for filtering Biodiesel and waste material water, merely SVO will definitely take a while to get through them.
As well, when nosotros build our filters, anything lower than 74 micron requires u.s. to line the filter with a capitalist mesh to keep the shape of the filter. Typically, we'll employ a 400 micron filter and so inlay and weld the finer mesh requested. This provides a very rigid filter while nevertheless allowing for the finer filtration micron rating.
So, go with the larger microns for filtering waste veggie to get the chunks out & go smaller for filtering biodiesel or waste matter water. In stainless, much smaller than 74 micron though & svo will usually take forever to go through it. If you need to filter down to that level, our poly bag filters would be meliorate suited.
Also, you may have run beyond people rating stainless weave in mesh ratings. Information technology's quite a bit different, but there is a relation. To help yous out with this, here's a handy conversion nautical chart betwixt mesh & micron.
So, in that location you have it, a quick demo on the dissimilar sizes of stainless screens!
If you'd like to exam out a few different sizes for your application, we sell stainless sample sheets in half dozen″ 10 half-dozen″ and 12″ 10 12″ in every micron size nosotros stock.
