Commissioning of the wastewater treatment plant in Baku Harbour

Every day thousands of oil tankers leave the port of the city of Baku. This also results in a large amount of contaminated wastewater, bilge water and ballast water from the oil ships. These discharges posed a risk to environmental safety and the technical solution was necessary.

 AWAS has developed a complete modern physical-chemical wastewater treatment system for bilge and ballast water precisely for these impurities. The special features of this technology are the low energy consumption, the compact design of the process technology, which is installed in a technical building, the easy maintenance, the high degree of automation of the control and monitoring of the technological process. AWAS designed, supplied, installed and commissioned the water treatment system.

The following process steps with the innovative AWAS products are included in the project: 

  1. The physical-mechanical pre-treatment of the wastewater with the AWAS Galaxy Tower with the discharge of all oils into an oil collection tank
  2. Further chemical-free treatment using AWAS Affinity
  3. Emulsion splitting, reduction of heavy metals and other ingredients on the molecular level by AWAS ADF flotation
  4. The retention of the smallest particles by AWAS sand and carbon filters
  5. Sludge treatment and dewatering

In addition to the process engineering, the delivery includes a control management system for external monitoring of the system operation.

Following the customer's contractual terms and conditions, AWAS guarantees the appropriate cleaning performance of the polluted water at the outlet under the defined discharge limits for further discharge into the Caspian Sea.

Unique water treatment plant installed in Kingisepp pond in Russia

The successful commissioning of the chemical-free Biolight Oloid Pyramid lake treatment plant took place on 25 July in the Kingisepp pond in Russia. It is the first installation of its kind in Russia and the second in the world.

The Biolight Oloid Pyramid water treatment system was specially developed for use in standing water. Using modern technologies, the system improves the molecular structure of the water and enriches it with oxygen both at the surface and at the bottom of the reservoir.

For the leisure park "Letniy" of Kingisepp, the upper side of the system was converted into a cascade well with illumination.

Successful Start-Up of Zero-Liquid-Discharge Plant at BMZ in Zhlobin, Belarus

AWAS has built and now put into operation a complex solution for highly salty and toxic wastewater, including: the concentrate from reverse osmosis systems and electroplating processes. The technical advantages of the AWAS Zero-Liquid Discharge process technology were the decisive factor for AWAS receiving the order from the largest steel company in Belarus, BMZ. The project, which worth approximately 10 million euros, was successfully supported by credit insurance group Euler Hermes.

The customer requested a waste water treatment plant for a volume flow of 25 cbm/h, which allows a reuse of the process waste water from the metal industry and discharges all pollutants as a dry residue with 5 - 15% humidity. AWAS has exceeded the expected parameter by achieving residual humidity of 2.9% (see the photo below).

-          2-stage Nano-Flotation with Photon Transmitter,

-          2-stage Reverse Osmosis

-          Crystallization plant with a vacuum evaporator.

Thanks to AWAS technology, the discharge of contaminated wastewater, as well as an environmental pollution of the Dnieper River was prevented.

New cosmetic waste water treatment project for renowned cosmetics manufacturer in Berlin

On the picture: AWAS pilot plant on site

During the production of various cosmetic products, waste water with fats, oils, surfactants, dyes, emulsions and other substances with a high COD content is produced.

The requirement to achieve a constantly low COD value at the discharge was the successfully implemented task of AWAS International GmbH.

Process engineering and design of the large-scale plant were successfully validated by our pilot plant on site at the customer's premises.

The best process combination determined is our specially developed nano-flotation with downstream separation of the solid and liquid phases with integrated sludge treatment.

We were thus able to offer the customer an economically efficient plant with minimal space requirements at the same time.

After the successful pilot tests, AWAS received the order in October 2018. Interested in testing our technology on your premises? Read more about pilot plants here or contact us!

Successful start-up of apron dewatering system for treatment of rainwater, floodwater and oily spillages at Muscat International Airport.

Protecting the environment is an important subject at Muscat International Airport. Especially the treatment of oily waste waters coming from heavy rainfall and subsequent contamination of the water with oil and kerosene.

Due to climate change, rainfall in the city of Muscat in Oman is steadily increasing, which places demands on the treatment of stormwater. AWAS has developed and planned an effective drainage technology for 4480 l/s, which was commissioned in the spring of 2018. The wastewater treatment and separation takes place physically and without filters by patented Galaxie 2002 vortex separators. In addition, the system is equipped with an automatic closing device against oil damage, which prevents the contamination of the water with oil and kerosene and thus the environmental impact.

Produced water solution for oil fields in Pakistan

In order to treat produced water for reinjection by Sonnek Engineering an AWAS Galaxie container was delivered in an encapsulated design at the end of 2015. The Galaxie is part of a turnkey solution in a modular container construction for an oil and gas field in Pakistan. After extensive testing and assembly of the individual components in Ternitz, south of Vienna, also the installation on is now complete and the unit can be started in September.

The Galaxy removes light materials and suspended solids from the wastewater. Due to the efficient purification performance of the vortex separator, the water only needs to be filtered prior to reinjectionthrough the high pressure pumps of the company Sonnek. There is no need for an expensive chemical cleaning.
