The Challenge

A New England-based hydroponic agriculture operation desired consistent water quality to feed growing tanks. Tanks required feed water with a precise dosing of nutrients. Feed water bacteria reduction and mold spore elimination were key concerns as well. Supply was inconsistent as water was used to top up tanks but was also required in large batches to refill tanks after tanks are drained and cleaned. Supply of 10 GPM was required for filling growing tanks.

Our Solution

Pure Flow designed a reverse osmosis (RO) system to feed the hydroponic growing tanks. Pretreatment included a water softener, carbon filtration, and cartridge filtration for sediment removal. The RO was a Suez E4 producing approximately 5 GPM of RO permeate. For bacteria reduction, a recirculating loop included UV and sub-micron filtration on the loop out. Minerals are dosed at each point of use with the RO feed ensuring that dosing is consistent.

The system met all end user requirements and Pure Flow was engaged to provide a duplicate solution for an expansion project.
