A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. In these situations the problem of how to adequately treat civil wastewater has to be tackled.
BONO ARTES has developed an activated sludge process called BIOCLAR; an advanced technology compared to conventional biological processes.
The high degree of innovation shown in recent years has allowed BONO ARTES to be awarded the contract of a package-type Biological treatment system designed to treat “human” waste water generated from a crude oil refinery located at Hassi Messaoud, Algeria.
The “Hassi Messaoud UTBS” project was developed by Saipem SpA, a company belonging to ENI group, one of the largest and most powerful Oil & Gas “turnkey” contractors, that has rewarded BONO ARTES thanks to the originality and efficiency of its proposal.
Each BIOCLAR module consists of an aeration basin and a settling tank. The key part of the treatment is the aeration chamber in which, thanks to its multistage composition, the oxidation process occurs.
While bacteria in the aeration tank decompose the sewage to form a suspended sludge, a settling chamber (clarifier) is placed after the aeration chamber to allow the micro-organisms grown in the aeration chamber to settle by gravity, forming sludge on the bottom of the clarifier.
Clarified water is discharged by gravity to a chlorination basin where residual bacteria is eliminating through chlorine dosing.
The entire plant is run automatically by a PLC (Programmable Logic Controller) that allows for negligible consumption and is supplied completely pre-fabricated. In fact the package is pre-assembled on skids and tested directly in the ARTES workshop.
The modular design is compact and easy to transport and requires minimal erection activities on site allowing for a quick start-up of the plant.
With this technology BONO ARTES has affirmed once again its role as the ideal partner in the realisation of Oil & Gas projects with the supply of innovative and efficient solutions to treat any kind of water even in the most extreme conditions.
