Swedish-made solutions for water and air treatment
Polyproject Environment
We design and manufacture plants and components for water and air treatment – from individual tanks to complete, turnkey systems. Everything is adapted to the plant it will operate in.
Tanks and cisterns
Open and closed cisterns, tanks and vats from 200 up to 200,000 litres – in glass fibre reinforced plastic, thermoplastic or with a liner. Every tank is designed for the medium it will hold and the place where it will stand.
Water treatment
Plants and components for treating scrubber water, condensate and wastewater. We work closely with some of the largest flue gas cleaning companies in the industry – in Sweden and internationally.
Air treatment
We supply both individual treatment units and complete installations with gas ducts, fans, stacks and circulation systems – built for aggressive media and high temperatures.
Fibreglass is a cost-effective alternative to concrete, steel, aluminium and wood. It is light, impact-resistant and does not corrode, giving a longer service life even in corrosive and extremely demanding environments. We have made products in glass fibre reinforced plastic for more than 50 years – often lined on the inside with thermoplastic for the best possible service life at the lowest cost.
Products
We work with all types of thermoplastics and glass fibre reinforced plastic, as well as steel products – in standard designs or custom-made.
Certified
Our management system is certified for sales, design, manufacturing, installation and service of components and plants for water treatment, air treatment and industrial processes.

Yes. We deliver both turnkey plants and custom-built components. Every product is adapted to the system it will be installed in.
We work with all types of thermoplastics and glass fibre reinforced plastic (GRP) for aggressive media and high temperatures, as well as all types of steel products.
Fibreglass is light, impact-resistant and does not corrode. It lasts longer than concrete and stainless steel, weighs less to transport and is a better environmental choice over time.
