Environmental Engineering S.A. has over 22 years Successful  Experience in managment of environmental issues with main focus in Municipal and Industrial Wastewater Treatment industry.


Municapal Wastewater
Environmental Engineering S.A. design - build - operate and maintain Municipal Wastewater Treatment Plants with the capacity of few hundred to hundred thousands of equivalent population. We have extensive experience in activated sludge installations (suspended and attached growth systems, MBR etc).


Industrial Wastewater
Since 1993 the company has delivered numerous turn key pojects in Industrial Wastewater Treatment Industry such as:

  • Slaughterhouses
  • Dyeing
  • Foood and Confectionery
  • Diary

Wastewater Treatments Systems

Activated sludge - Secondary
Secondary treatment is designed to substantially degrade (>95%) the biological content of the wastewater which are derived from human waste, food waste, soaps and detergent.
Activated sludge - Tertiary
The purpose of tertiary treatment is to provide a final treatment stage to further improve the effluent quality before it is discharged to the receiving environment (sea, river, lake, wet lands, ground, etc.). More than one tertiary treatment process may be used at any treatment plant. If disinfection is practised, it is always the final process.
Reed Beds Muicipal Wastewater Treatment
Reed - beds (Constructed wetlands) are artificial swamps using reed or other marshland plants to form part of small-scale sewage treatment systems.
Rotating Biological Contactors
Rotating Biological Contactors: The rotating packs of disks (known as the media) are contained in a tank or trough and rotate at between 2 and 5 revolutions per minute. Commonly used plastics for the media are polythene, PVC and expanded polystyrene. The shaft is aligned with the flow of wastewater so that the discs rotate at right angles to the flow with several packs usually combined to make up a treatment train. Biological growth is attached to the surface of the disc and forms a slime layer. The discs contact the wastewater with the atmospheric air for oxidation as it rotates. The rotation helps to slough off excess solids. The disc system can be staged in series to obtain nearly any detention time or degree of removal required. Since the systems are staged, the culture of the later stages can be acclimated to the slowly degraded materials. This method has exceptional low operation cost.
Leachate Treatment
Leachate from a landfill varies widely in composition depending on the age of the landfill and the type of waste that it contains. It can usually contain both dissolved and suspended material. Environmental Engineering S.A. applies technologies such as SBR and MBR and Reverse Osmosis for final treatment.
MBBR System
Moving Bed Biofilm Reactor (MBBR) processes improve reliability, simplify operation, and require less space than traditional wastewater treatment systems. This technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm attached to the mobile biocarriers within the system automatically responds to load fluctuations. The sedimentation as well as disinfection stages can be skiped.
COMPACT biological Treatment
Compact system for small villages from 5.000-15.000 inhabitants. MBBR systems are compact, simple to operate and very efficient for removal of BOD, ammonia and nitrogen.
Industrial Wastewater Treatment
For the industrial wastewater treatment we apply, based on each specific case, Physico-Chemical treatment, with sedimentation or flotation, biological treatment, filtration, oxidation with ozon etc.
