No. Nordic’s high-level filtering and disinfection means that discharge is essentially filtered water with traces of nutrients. More than 99% of phosphorus, biological oxygen demand (BOD) and total suspended solids (TSS) are removed before the effluent is discharged into the ocean. High discharge treatment ensures that there is no significant impact to the surrounding waters or marine life at the point of discharge.
