Still using old technologies, aggressive chemical liquids (acids, alkalis, salt solutions, production effluents) and waste water are stored 
in metal tanks, which over time are affected by chemical corrosion, leaky and require repair or renovation. UAB "AQUATERA" has developed a unique technology that allows renovating steel tanks with plastic material. The size of the material capacity can reach up to 3000m3 and more. During the renovation, the old metal tank is covered with plastic from the inside and basically the customer receives a new
plastic tank that is installed inside the old metal tank. In this way, the old metal container becomes completely resistant to corrosion processes and the service life of the metal container
is significantly extended when renovating it with plastic.
