Municipal Water Treatment
The discharge limits for water become more and more stringent, motivating many municipal and industrial waste water plants, to implement both biological and chemical systems for their reductions.
Nordisk Aluminat’s product range is produced on the fines raw materials available, ensuring waster water treatment plants the highest level of efficiency.
All Nordisk Aluminat A/S’ Sodium Aluminate solutions are produced according to EN 882 (Chemicals used for treatment of water intended for human consumption). Aluminum products reduce chemical sludge production compared to iron, due to the low molecular weight of AI. Aluminates raise the alkalinity of the water, eliminating the need of lime or hydroxides. Additionally Sodium Aluminate has a very low content of heavy metals.
The high content of AI in aluminates, facilitates lowered transport costs.
NordPac 18 – Poly Aluminum Chloride
NordPac is produced according to EN 883 (Chemicals used for treatment of water intended for human consumption). With slightly larger molecyles compared to Sodium Aluminate, NordPac 18 provides excellent flocculation properties.
NordPac is also suited for Microthrix (filamentous bacterium) control in wastewater.
EC No. 215-100-1
Registration No. (REACH) 01-2119519249-35-0011
Sodium Aluminates comply to EN 882 “Chemicals used for treatment of water intended for human consumption”
EC No. 215-477-2
Registration number (REACH) 01-2119531563-43-0044
NordPac 18 comply to EN 883 “Chemicals used for treatment of water intended for human consumption”
In environments with low temperatures, Sodium Aluminate 38% is recommended.
NordPac has less influence on pH compared to alum, and can also be used for retention and dewatering as well as an anionic trash scavenger.
