Municipal water treatment
Aluminium based flocculants
Purification of wastewater
Every day many litres of water are used for both professional and private use. This results in enormous amounts of waste water that needs to be cleaned every day.
If the wastewater isn’t treated properly it can have a significant negative impact on plants and animals. Eventually, it can result in a shortage of pure and clean drinking water.
Our products are an essential part of the cleaning process, that turns wastewater into pure and clear water – preserving our nature and drinking water.
Essential in Municipal Water Treatment
The municipal waste water treatment plants are subject to rigorous discharge limits that only will get more and more strict by time. This means that biological cleaning isn’t enough to meet these requirements. A chemical cleaning of the water is also necessary to achieve a satisfying level of purification.
With aluminium based flocculants it’s possible to filter out tiny particles that are invisible to the eye, but still can pollute nature and drinking water. Alumichem’s product range is produced of the finest raw materials available, ensuring waste water treatment plants the highest level of efficiency.
Used in Small Wastewater Treatment Plants
It’s not only big factories and municipals that may need treatment of their wastewater.
Especially in the Nordic countries, the authorities tighten the requirements for discharge of waste water. Because of this, private homeowners of all year-round and leisure homes are faced with new demands for cleaning their waste water, before it is led out or submerged.
Flocculants remove phosphor
Depending on the area where the water is led out or submerged there are different requirements. In some areas, it is enough to remove organic matter. In other environmentally sensitive areas, both phosphor and nitrogen must be removed. One way to solve this is to install a small wastewater treatment plant where microorganisms and flocculants will purify the water before it is led out.
AluPAC (Poly aluminium chloride) is an effective flocculant for removal of phosphor in small wastewater treatment plants. Most suppliers of these also offer a service where flocculant filling is included. Alumichem delivers AluPAC for suppliers of small wastewater treatment plants – in bulk, IBC or cans.
All Alumichem Sodium Aluminate solutions are produced according to EN 882 (Chemicals used for the 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 for lime or hydroxides.

AluSAL 45% has a higher viscocity compared to AluSAL 38% due to the higher content of aluminium. It represents a strong alternative to AluSAL 38% when transporting over long distances.
In environments with low temperatures, AluSAL 38% is recommended.
