Biodiesel Laminar Flow Separators
Hydrasep® for your Biodiesel Production
Hydrasep®, Inc. has developed a new line of separators specifically tailored to the needs of Biodiesel production. Our BD separators are specifically designed to continually separate glycerin from biodiesel, wash water from biodiesel, and remove water from feedstock. We customize to meet your specific process needs.
If your process is continuous, if you use high shear reactors, or if you want to upgrade your batch process to sequence batching, we can assist you. If you want to double your production without doubling the size of your plant, we can assist you. Depending on your process, a Hydrasep® will handle two or more sequenced batch reactors, thus operating in a continuous mode.
We offer carbon steel or stainless steel construction for atmospheric, blanketed, pressure or vacuum operation. Thermal insulation and heaters can also be provided.
We have a system tailored to best suit your needs in all of these scenarios:
- pre-treat your waste oil feedstock,
- separate water after acid esterification
- separate glycerin from methyl esters
- seperate water from acid estification process
- separate wash water from biodiesel
- recover solids from dry wash
- or recover biodiesel from wastewater
A Hydrasep® separator can be used to replace slow, bulky and heat consuming decanters. The separation process becomes continuous, saving time, valuable real estate and energy. The Hydrasep® has no moving parts, no replaceable parts and does not consume any power. Unlike a centrifuge, it requires no power input and is virtually maintenance free.
Save time and heat over lengthy batch decanting. Save capital and operating cost, power consumption and maintenance on centrifuges.
Get the results you are looking for.
Hydrasep® biodiesel separators increase production at lower capital cost and virtually no operating cost.
The descriptions below will help guide you towards selecting the product best suited for your application:
