Small improvements can make the differance

We have specialized persons that only work with rebuilds and improvements of water treatment facilities. Sometimes a plant needs to be upgraded with new equipment such as pumps, scrapers, diffussors etc. In other cases a rebuild of existing process on site is necessary. Our experts have long practical experience in solving such missions.

We can help you today

We are experienced in designing, re-
building and improve operations for
water treatment facilities. After an
inspection on site we can quiclky
make an assessment of the scope of
work and make a recommendation.
Sometimes it´s only minor adjust-
ments such as replacing pumps and
other equipment and sometimes it
can be replacing larger systems such
as scrapers or an entire diffussor system.
