CIP Water QualityWater used for flushing, cleaning and disinfecting of membrane filtration plants mustconform to the following standards to obtain best possible service.It is a prerequisite that the following standards be adhered to for membraneguarantee to be valid. It is also recommended that the water be analyzed atleast every three months to ensure proper quality. If the water quality does notmeet these standards, consult a Niro representative. Every six months themust be sent to Niro for review.analysis• Iron Less than 0.05 PPM• Manganese (MN) Less than 0.02 PPM• Silicate (Si0 2 ) Less than 10 PPM• Aluminum (Al) Less than 1 PPM• Hardness as (CaCO 2 ) Less than 10 gr/gal (170 PPM)• Particles Less than 25 microns• Turbidity Less than 1 NTU• Silt Index Less than 2.5 SDI• Total Plate Count Less than 1000 per ml• Coli Count 0 per 100 ml• Chlorine (RO and NF only) 0 PPM66
Oxidizer IntoleranceIf you have a reverse osmosis or nano-filtration system, the membranes have no tolerancefor oxidizers. Introduction of any oxidizers, especially chlorine (sodium hypochlorite),will cause permanent damage.Niro will not assume any responsibility for damaged membranes of oxidizers come incontact with the membrane.Defoamer IntoleranceUse of anti-foaming agents is not recommended since they can cause irreversible loss offlux.* If use of anti-foaming is necessary, please consult a Niro representative.No chemical that has not been approved by Niro should be used for membrane cleaningor shall come in contact with the membranes.Niro will not assume any responsibility for damaged membranes if unapproved chemicalscome in contact with the membranes.A common component of anti-foaming agents in silicon, which is the primary cause ofthe flux loss. Silicon is also found in many lubricants, which also should not comein contact with the67
