Water and wastewater treatment
In Finland we work with municipal wastewater treatment plants and industrial water treatment, especially at pulp and paper mills. Outside Finland our offer depends on the case. Tell us what you need, and we will tell you openly whether we can help.
What we do in Finland
- Municipal wastewater: precipitation and flocculation chemicals, phosphorus removal, sludge dewatering and odour control
- Industrial wastewater: pulp and paper and other industries
- Process and circulation water: clarification and fibre recovery at paper and board mills
- Trials and follow-up: trial plans, dosing, measurements and reports, followed by process optimisation
Examples of what we can offer
Whether we can supply abroad depends on the product and the country, so we check each enquiry separately. Typical examples:
| Need | Examples of solutions |
|---|---|
| Phosphorus removal and precipitation | iron and aluminium based precipitation chemicals, dosing plans and trials |
| Flocculation and sludge dewatering | polymer flocculants, coagulants, dosing equipment |
| Odour and corrosion: hydrogen sulphide | hydrogen sulphide control in sewer networks and sludge treatment |
| Circulation water clarification and fibre recovery | dissolved air flotation (DAF), fibre recovery filters |
| Shower and sealing water for paper machines | self-cleaning filters for clarified water |
| Pre-treatment of process and effluent water | self-cleaning fine screens |
| Small and temporary treatment needs | local, modular wastewater treatment solutions |
| Fouled equipment | heat exchanger cleaning and cleaning chemicals for tanks and pipes |
Outside Finland: case by case
We represent most of our water treatment manufacturers in Finland only, and in other countries they have their own partners. That is why we look at each enquiry separately. If we cannot supply the solution ourselves, we will tell you so and, where possible, put you in touch with the right supplier.
Frequently asked questions
Do you supply water treatment chemicals outside Finland?
Case by case. Many of the manufacturers we represent in Finland have their own partners in other countries. Tell us what you need, and we will tell you whether we can supply it or who can.
Can you run trials at our plant?
In Finland, yes: we plan the trial with you, follow the dosing and the results and report them. Outside Finland we agree on this case by case.
What can you supply abroad without restrictions?
Industrial cleaning chemicals, the HeatFlow Pro unit for cleaning heat exchangers, ruby nozzles, loading hoses, screen baskets and screen plates, and the Crawler duct cleaning robot.
