Another classic example of a unique VA Filtration technology doing the job smarter - our Lo-Cross-Flo mobile microfiltration system. This is not a cross flow filter system, but uses a dead-end filtration mode, where no wines cross the membrane.
Utilising the considerably increased surface area to compensate for any loss in flow rate, we feed semi dead-end, as well as having a lower flux rate per m2 with an immediate lower trans-membrane pressure.
When needed, the filtered solids within the membrane can be backwashed into a system storage tank where they can be further filtered using cross flow filtration.
This system, currently operating in Australia, South Africa and USA, creates a far gentler, one-step filtration for your wine.
