ErtelAlsop Depth Filtration Systems for Cannabis Industry Excellence


From high quality water to achieving a clear and pure extract, excellence in filtration is as crucial to the Cannabis Industry as it is to the Food & Beverage and Pharmaceuticals Industries.

Extracts of the active ingredients from the Cannabis sativa plant are now common options for various applications in North America. Cannabis oil extracts can be further processed to make edible products or standard extracts like medical marijuana extracts or hemp oil.

The filtration stage of producing essential cannabis oil, medical marijuana, or hemp oil is key to ensuring product safety and quality regardless of the desired result.

That’s why reliable cannabis extract producers of medical-grade marijuana and hemp oil turn to precision equipment to achieve excellence in every aspect of the liquid product, from distillation, taste and smell to the right appearance.

The right combination of proper techniques and tools is the difference between a clear, amber extract, and a muddy, undesirable product that contains plant particles, debris, and unwanted lipids.

From research and development applications in the laboratory, to full production runs, ErtelAlsop’s food grade depth filters, equipment, and filter media are staples for producers looking for a professional result.

The 2-Step Filtration Process for Cannabis Purification

After CO2 extraction or cold ethanol extraction, the slurry is run through an initial filter stack. Most processes then pump the liquid through a filter that catches biomass, and finally another filter media grade as many times as necessary to finalize the product and remove unwanted compounds.

Step 1: Chlorophyll Removal

Achieve a clear product that can be applied to various applications. The muddy, dark brown or green appearance in the raw extract comes from the presence of chlorophyll. Activated carbon filtration effectively removes and adjusts the color and taste of your product without affecting the integrity of the product.

The results above were achieved solely through activated carbon filtration, using ErtelAlsop’s Micro-Clear MC35C activated carbon filter media.

Step 2: Polish Your Product Before Bottling

Filter media like Micro-Media M704 with 0.45 micron retention finishes your product by removing fine particles and debris that can affect purity and appearance, and prepares it for final processing or bottling.

As with all ErtelAlsop filtration equipment, you’ll find the right filter media for your specific operating conditions. ErtelAlsop offers the widest varieties of filter media and construction techniques to provide good particle retention, clear filtrate, high flow rates, and dry filter cakes, with our variety of filter media finishes and separation capabilities.
