Over the years we have specialized in special fabrications, with greater engineering requirements for the design of them with a high level of specialization and quality. Becoming a reference company within the sector of wastewater treatment, adjusting to the technical needs of each company that creates a system of purification, storage of chemicals, industrial processes, desalination, equipment for biogas plants, and so on.

1. Storage tanks

Over the years we have specialized in special fabrications, with greater engineering requirements for the design of them with a high level of specialization and quality. Becoming a reference company within the sector of wastewater treatment, adjusting to the technical needs of each company that creates a system of purification, storage of chemicals, industrial processes, desalination, equipment for biogas plants, and so on.

2. Depuration

BUPOLSA offers you definitive and ecological solutions in wastewater treatment.

We present our different models for the disposal of solid and liquid waste.

3. Double-walled

BUPOLSA's double-walled tanks are designed in glass-fibre reinforced polyester (GRP) for the storage of all types of substances.

BUPOLSA has the patent 2644 of double wall tanks for the storage of hydrocarbons, having been taken as a reference model for many other manufacturers.

The double wall tanks have an interstitial space between the two walls. They are designed to avoid spills and consequently the contamination of the subsoil.

By means of a pump, a vacuum is made between the two chambers of the tank, the vacuum gauge will mark the permanence of this vacuum, in case of leakage the needle will mark zero.

4. Isotherms

The BUPOLSA isothermal tanks are manufactured by means of a sandwich structure composed of polyester reinforced with fiberglass (PRFV), closed cell polyurethane foam and finally another layer of PRFV.

BUPOLSA has its own machine for spraying polyurethane foam, so the manufacture is faster than other manufacturers.

The polyurethane foam used by BUPOLSA is of high density and closed cell so it provides a high quality insulation. In this way we isolate the product stored inside from the external meteorological conditions, being able to have temperature contrasts of more than 90ºC.

5. Pressure and Vacuum

BUPOLSA's pressure or vacuum tanks are made of glass fibre reinforced polyester (GRP) and are an essential element for storage or for use in pressure processes, such as: pneumatic impulsion of liquids, gas saturation on liquid, cartridge filters, sand filters, etc. These tanks are designed to contain both fluids and gases at pressures different from environmental or atmospheric pressure.

6. Scrubbers and chimneys

BUPOLSA Scrubbers are made of polyester reinforced with fiberglass (PRFV) and is an equipment designed to purify the air by means of a washing process that allows the removal of gases and contaminating particles present in the gases. Specially designed for gas streams generated by industry and wastewater treatment plants.

The installation works by putting a gas stream in close contact with a flushing liquid. Due to this contact, certain gaseous components dissolve and remain in the water. Therefore, there is a transfer of components in the gas phase to the liquid phase, also called absorption. The solubility of the particles in the liquid will determine to what extent the gaseous components dissolve in that phase.

7. Covers

The BUPOLSA covers are made of glass fibre reinforced polyester (GRP) and tailored to the customer's needs. They are removable covers designed according to the space to be covered and the load to be supported. They are suitable for any type of construction such as thickeners, sludge tanks, biological ponds, homogenisation tanks, etc.

The roofs are modular and self-supporting with cylindrical and rectangular geometry. Special designs are made, adapted to the characteristics and needs of each action. A multitude of accessories are also available, such as manholes, anchors, etc.

8. Pipes and accessories

BUPOLSA's fittings and pipes are made of glass fibre reinforced polyester (GRP), galvanised steel or stainless steel, and are made to measure according to the customer's needs. They are complementary elements to the rest of BUPOLSA's products and allow the registration, manipulation, connection, control, etc. of the tanks and equipment.
