NSF 40, 245 and 350-Reuse

Our technologies and designs have been rigorously tested and certified at a NSF facility for 40, 245, and 350-Reuse.

The EZ Treat Re-Circulating Synthetic Media Filter is the first (as of 8/23) biologically-based blackwater treatment system certified and listed as passing NSF 350 for Water Reuse.

What is the NSF 350 Blackwater Certification?

Wastewater certification through NSF 350 is a rigorous process that manufacturers pursue to display the NSF mark on their products. This process includes 26-weeks of continuous third-party testing during which system maintenance or process adjustments are not allowed, It includes a review of design specification compliance, and a satisfactory 5-year audit history.

If a manufacturer has successfully completed the NSF 350 certification review, their product will have demonstrated satisfactory treatment for biochemical oxygen demand (BOD5), total suspended solids (TSS), turbidity (NTU), and bacteria (e-coli), among other test parameters.

Being tested and certified by NSF to meet their 350 standard is a great way for a product to show that it consistently meets high water quality requirements.

NSF 350 enable the reuse of treated effluent to be used inside residences and commercial facilities. Being able to produce a treated effluent that can now be used for expanded non potable activities such as toilet flushing, car washing, unlimited irrigation allows the ability to re-think the water budget and use water more efficiently.

Water reuse: why is it important?

Wastewater is water affected by human activities. Any wastewater that is discharged to the environment without suitable treatment might cause environmental pollution. As a matter fact 80% of urban wastewater is still discharged into the natural environment without any treatment.
Wastewater reuse or water recycling is the use of treated wastewater (or untreated wastewater) for a beneficial purpose.
Some of the key advantages of recycling treated wastewater is to protect water resources by reducing water pollution discharges, beneficial recharge and eliminating the need for water to be removed from natural habitats.

What is the NSF 40 Certification?

NSF/ANSI 40 is a standard for residential wastewater treatment systems with rated capacities between 400 and 1,500 gallons per day (1,514 and 5,678 liters), meeting an effluent quality limit of CBOD equal to or less than 25 mg/l and TSS equal to or less than 30 mg/l.

NSF/ANSI 40 is a requirement in conjunction with NSF 350 certification.

What is the NSF 245 Certification?

NSF/ANSI 245: Wastewater Treatment Systems – Nitrogen Reduction defines total nitrogen reduction requirements for residential wastewater treatment systems with rated capacities between 400 and 1,500 gallons per day (1,514 and 5,678 liters)

Nitrogen reduction provides access to the on-site residential wastewater market in which total nitrogen reduction is a requirement. NSF/ANSI 245 requires 50% reduction for total nitrogen to meet the growing demand for nutrient reduction in coastal areas and sensitive environments. Certification to NSF/ANSI 245 also meets all the requirements of NSF/ANSI 40.
