WVO Filter VS WVO Centrifuge

First what are these two types of filtering systems?

WVO (waste vegetable oil) centrifuge:

A centrifuge is a piece of equipment, generally driven by a motor that puts WVO in rotation around a fixed axis, applying a force perpendicular to the axis. The oil entrifuge works using the sedimentation principle, where the centripetal acceleration is used to evenly distribute substances (WVO) of greater and lesser density. Traditional centrifuges use an electric motor to spin a bowl at high RPM and create a force like gravity but up to 3000 times the force of gravity. This speeds up partical and water separation enormously. Separation levels that might take months using only gravity take less than a minute in a centrifuge. And most industrial centrifuges are continuous so dirty WVO can be fed in and clean/dry WVO fuel exits. accumulatMost centrifuges must be stopped to remove the contaminants but some systems are available that allow automated cleaning without stopping the centrifuge.

WVO (waste vegetable oil) Filter:

A gravity or pressure filtration system, the WVO is simply poured into a filter bag placed over a container into which the WVO is collected. These filter bags come in different microns or levels of filtering ability to fit your needs.

Which is better well it all comes down to how much WVO you want to process, how much time you have to spend processing how much money do you want to spend and how hard do you want to work.

With WVO Filter system Oil will run through a 100 micron filter bag at 2-5 gallons per minute however, if the oil is dirty or just creamy the flow rate will deteriorate rapidly. Pre-heating the oil helps as does larger/longer filter bags.  My advice is to only use filter bags after settling. This means time waiting for the oil to settle. Cartridge WVO filters, tee strainers ECT, should be used only with heated oil or heating of the filter.Waxy particles in cool oil quickly clog cartridge filters and no amount of pressure will resolve this issue. Any mechanical cartridge filter will require an amount of pressure to work, finding an appropriate pump, plumbing and pressure relief system can be difficult and large spills are possible.

ith WVO Centrifuge Forced Settling can clean WVO to sub micron levels as well as removing heavier liquid contaminants such as water.f you are looking at having to deal with hundreds of gallons or more a centrifuge is your only solution. A WVO centrifuge is required to remove solid and liquid contaminants from the WVO regardless of size. Centrifuges have proven to be quite efficient in the cleaning of waste vegetable oil and reducing the free fatty acids in the pre-processing of Biodiesel. They also have proven to remove glycerin during the processing. Contaminant particles as small as 1/10^th of 1 micron are removed, all without the use of a disposable costly filter element. There is no better way to make quality biodiesel quickly. What takes many hours for gravity to separate down; a centrifuge can separate instantly in seconds.

 

The Benefits of Conversion from Diesel to Biofuel (WVO)

ue to unstable oil price situation in the world market, many countries have been looking for alternative energy to substitute petroleum. Researches on the use of waste vegetable oils (WVO) as fuel substitutes in diesel engines have been done in many countries with much success.
Biofuel is diesel fuel that is made by reacting waste vegetable oil (WVO) with other common chemicals. Biofuel may be used in any diesel automotive engine in its pure form or blended with petroleum-based diesel.
Biodiesel is nontoxic and biodegradable, that it can help reduce dependence on foreign oil and cut down on greenhouse gas emissions. It’s an oxygenated fuel, so it burns more completely than other fossil-based products. Filling your car with biodiesel cuts down on emissions of unburned hydrocarbons, carbon monoxide, sulfur and the nastiest of all diesel byproducts–particulate matter.
Cars built since 1994 that are already equipped with diesel engines can run even 100 percent biodiesel with little or no modification. Some work will be needed to run on pure vegetable oil, but you may be able to do it yourself.
The energy content of a given amount of waste vegetable oil is only a little less than that of diesel fuel, and is more than for gasoline. Therefore, power and fuel economy on WVO is almost the same as on diesel. Under most conditions, there is little or no perceptible difference to the driver between driving on diesel and driving on WVO.
WVO system reliability has improved greatly in a short period of time. The growing base of WVO users have contributed their knowledge to that gained in production and sale of systems.
Biodiesel is a natural fuel system lubricant. Independent studies by Stanadyne Automotive Corp. and Southwest Research Institute show biodiesel improves the wear or scarring of metal parts within the fuel system.
The flash point (the point at which fuel ignites) for biodiesel (B100) is a minimum of 300 degrees versus about 125 degrees Fahrenheit for regular petroleum diesel #2.
Biodiesel is also non-toxic and biodegradable. These factors make biodiesel one of the safest fuels to use, handle and store.
