WATER TREATMENTS

The average working experience is now over 20 years in the Water and Waste Water treatment plants in the Industry as well as in Oil and Gas sector, with almost all employees sharing the same technical expertise.

Avietta is now in condition to supply a complete range of applications spanning from water and waste water treatment to the oil dehydration/ desalting, from the water injection to the Zero Liquid Discharge and chemicals crystallization.

Our area of work has no limits worldwide, with the ability of application of the various standards and regulations of the Countries where we offer our services: as an example Standards ISO, IEC, ASME, ANSI, IEC, EN, NORSOK, ANFOR, GHOST, CNS, etc..

As proof of our commitment to quality, we hold with our partners a complete range of Quality Certifications, including ISO 9001 for Engineering and Supply activities, BS OHSAS 18001 for the Health and Safety Management System, and ISO 14001 for the Environmental Management System.

The world challenge is today the way of managing the waste waters:

  • How to collect them
  • How to treat them
  • How to discharge them.

Water recovery is an essential part of environmental management and minimizes the consumption of water resources. The utmost aim is to reduce the production of waste waters, optimizing the majority of the processes at the maximum extent.

As an EP contractor present in the world market, Avietta is actively involved in finding always new solutions. Avietta’s challenge is to apply the more up-to-date technologies and the more reliable solution to each industrial case.

There are many processes for wastewater treatment. They include physical, biological and chemical treatment. Sludge treatment has mainly the purpose to reduce the volume of wastes to disposal or reuse and to produce environmentally safe fluid waste stream. Avietta applies a wide variety of technologies for waste water treatment and water recovery:

  • PRODUCED WATER TREATMENT AND INJECTION
  • SLUDGE TREATMENT
  • WET AIR OXIDATION
  • ZERO LIQUID DISCHARGE

Wellheads fluids can be simplified in crude oil, natural gas and brine or sand. The first operation is the separation of the components before transport, reinjection or disposal.

Once separated these components shall be processed in order to obtain a safe and economical storage of oil and gas and/ or transport by pipeline, tanker or truck.

Therefore the production of Oil & Gas involves a number of surface unit operation between the wellhead and the point of delivery. These operation are called field handling or oil processing.

Oil processing includes also water treatment which involves the produced waters for reiniecting for formation flooding or reservoir pressure maintenance.

Oilfield operation includes as principal:

  • Separation (Oil/ Water/ Sand)
  • Dehydration Desalting
  • Sweetening
  • Gas removal
