Effluent treatment plants from Veolia Water Technologies South Africa (Veolia) are designed to treat both municipal and industrial effluent, which consists of wastewater, sludge or sewage. These effluent treatment plants are tailored to remove harmful pathogens, clear hazardous chemicals, detergents and toxins, and separate and extract valuable substances from effluent.
To treat water efficiently and effectively in our country’s numerous effluent treatment plants, the recommended water treatment chemical used by Veolia is the Hydrex™ 6000 series. This series is ideal to treat flocculants like anionic emulsions, anionic powders, anionic beads, cationic emulsions, cationic powders, cationic beads; as well as organic and inorganic coagulants. Aerobic and anaerobic biological processes are also used in effluent treatment plants.
AEROBIC AND ANAEROBIC BIOLOGICAL PROCESSES
Aerobic and anaerobic biological digestion is harnessed to treat waste, provide heat and produce biogas and compost in our effluent treatment plants. The digesters aid in upgrading the quality of effluent that is released into the environment and form a major component in water recycling from high organic load to wastewater.
Aerobic and anaerobic biological process that Veolia uses in effluent treatment plants include:

This is a highly efficient, cost-effective and easy to install advanced technology that is intelligent and compact in design. It uses biological aerated filters (BAF) to remove carbon, nitrification, denitrification and post-denitrification in effluent. Read more
MBBR (Moving Bed Biofilm Reactor)
Based on the biofilm principle, this technology uses the advantages of activated sludge and other biofilm systems. It is used for numerous applications from food & diary to chemical, pharmaceutical, distilling & brewing and oil refineries, among others. Read more
Also known as Biothane UASB, it uses an up-flow anaerobic sludge blanket and patented double baffle plate 3-phrase separator to treat various kinds of effluent. This technology, which has been proven for over 20 years, has a high volumetric loading rate and a compact reactor footprint among other advantages. Read more
BIOSEP Membrane Bioreactors
A high performance solution that combines aerobic biological treatment using activated sludge and membrane filtration to treat effluent. This process provides exceptional quality treated water and high COD removal with no final clarification. It also reduces reagent levels in phosphorus elimination. Read more

SOUTH AFRICAN EFFLUENT TREATMENT PLANT REFERENCES
Anaerobic effluent treatment plant, Stellenbosch, Western Cape
South Africa’s first Biobulk® effluent treatment plant uses Biobulk® CSTR (Continuous Stirred Tank Reactor) technology – a robust and proven green technology that treats effluent with significant amounts of suspended solids. This is the anaerobic equivalent of conventional activated sludge digestion systems. Read the case study here.
Ceres effluent treatment plant, Western Cape
After 18 years of operation, certain systems needed overhauling to achieve the plant’s effluent discharge standard with maximum efficiency. Veolia conducted an audit, the results thereof showed that the digester compartments needed overhauling, the parabolic screen required replacing and several systems needed refurbishing. Read the case study here.
OVERSEAS EFFLUENT TREATMENT PLANT REFERENCES
FGD Scrubber effluent treatment plant, Monfalcone, Italy
A coal-fired generation plant installed a state-of-the-art FGD (flue gas desulfurisation) system at their effluent treatment plant. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station. Read more here.
Pretium Resources Brucejack gold mine, northern British Columbia, Canada
A recently acquired contract that will see Veolia supply proven proprietary processes to treat up to 10 000 m³ of mine effluent per day. It will be treated with a permanent effluent treatment system using robust and compact technologies. Read more here.
The Pearl GTL project, north-east Qatar
Petroleum giant Shell requested a ZLD facility with 12 different water streams treated when entering the plant. Treatment of these streams is required at 8 different locations, and 5 different recycled water qualities are required. Read more here.
