Marijuana Reverse Osmosis System – Cultivation Treatment Process

 

 

Lifestream was recently contacted to bid on a proposed marijuana reverse osmosis project.   The project was for a licensed recreational marijuana cultivation facility near Pueblo, Colorado.

Cultivation facilities often desire reverse osmosis permeate water.  But, why?

Growers often desire water that is free of all contaminants and minerals (ions, silica, and organics).  In short, they desire pure H20.

Growers working with pure water can then mix in nutrients.  Thus, creating their own plant specific nutrient blend.

Water Chemistry and Pretreatment Equipment

Reverse osmosis systems can become damaged by a number of factors or contaminants present within the source water supply.  Thus, Lifestream can’t recommend a treatment process with confidence without first understanding the source water’s chemical makeup.  Lifestream can recommend equipment and injections (pretreatment) ahead (upstream) of the reverse osmosis system only after the source water has been laboratory tested.  Example pre-treatment equipment includes: water softeners, carbon filters, sediment filters, UV lamps & chemical injection systems. This equipment protects the marijuana reverse osmosis system from scaling, fouling, and chemical attack.

 

Sizing Pretreatment Equipment and Reverse Osmosis Systems –

The following information is with regards to this specific project.  The feed water flow limited pre-treatment and RO equipment sizes at this job site.  The peak water flow was flowing at 10 – 11 GPM at 40 PSI out of the end-users well.  The slow flow rate and low pressure limited the size of equipment that the end-user could install at their cultivation facility.   Pre-treatment equipment often requires peak flow rates to backwash media.  Backwashing media frees trapped sediment from pre-treatment equipment.  Subsequently, we were able to design a RO system capable of producing reverse osmosis product water  at 10,000+ gallons per day.  Pre-treatment equipment was designed to operate under these limiting conditions as well.
