COMPANY HISTORY
Established in 1979
HYDROTECH ENVIRONMENTAL is a group of
specialized Greek Companies in the field of
environmental protection and especially in the study,
design, construction and operation of domestic sewage
and industrial wastewater treatment plants. The
company group consists of Hydrotech S.A., two
personal companies of George and Andreas
Ganatsios as well as Hydrotech Environmental A.
Ganatsios & Co E.E.
The founding member of the companies is Dr George
Ganatsios, Chemical Engineer, with experience of at
least 35 years in the field of environmental protection.
Since 2007, HYDROTECH ENVIRONMENTAL has
implemented the Ydro Process® in various wastewater
treatment units and by altering parameters has
achieved the pioneering and unique method invention
of sludge elimination, simultaneously achieving plant
optimization and cost reduction.
HYDROTECH ENVIRONMENTAL has entered into
various strategic cooperation's offering solutions in this
area. 2
ACTIVITIES & SCOPE
The basic activities of Hydrotech
Environmental are:
1) Study and Design of municipal &
industrial wastewater treatment plants
2) Construction of turn-key municipal &
industrial wastewater treatment plants
3) Operation and Optimization of
Wastewater treatment plants
4) Implementation of the Ydro Process ®
for elimination of the excess sludge
production in wastewater treatment plants
3
The Ydro Process ®
The Ydro Process ® creates the suitable and optimum conditions for the
growth, the reproduction and the operation of the microbial product which
contains:
1. Hydrolyzing Enzymes
2. Facultative cultures
3. Aerobic cultures
4. Micronutrients
5. Bio-enhancers
The combination of the Ydro Process ® and the addition of the suitable
microbial product results in:
1. Total degradation and elimination of the excess sludge
2. Improvement of the effluent of the plant (BOD,COD,SS,TN,TP etc)
3. Liquefaction and elimination of FOG (fats, oils and grease) in the treatment
plants and in pumping stations
4. Elimination of odors
5. Possible reduction of the energy consumption in the aeration stage
6. Possible increase in the biogas production with a simultaneous increase of
methane content in it
7. Significant reduction of micropollutants
8. Higher resistance to incoming organic shocks 4
The Ydro Process ®
• The Ydro Process ® is the continuous adaptation of the microbial population to the
conditions of each process according to the targets.
• The added bacteria become dominant and the existing ones are adapted and
assimilated to coexist and collaborate.
• In suitable conditions the added microorganisms produce enzymes which enhance the
biological process.
• The degradation of complex organic molecules, oils and greases into simple ones leads
to the production of Volatile Fatty Acids (VFAs), i.e. Acetic, Butyric, Propionic Acid etc.
• The VFAs are then easily converted to Carbon Dioxide (CO2) and water (H2O) in aerobic
conditions, methane (CH4) and hydrogen (H2) in anaerobic conditions and free available
energy.
• The breakdown and molecule destruction occurs up to 80% of the total biomass
through the metabolic pathway called Catabolism. Only 20% of the total biomass is
utilized for the synthesis of new bacteria.
• The Ydro Process ® requires less oxygen supply as the Ammonia (NH4+) is converted
to Nitrites (NO2-) and then Nitrogen (N2) without first being converted to Nitrates (NO3-)
where the largest consumption of Oxygen occurs depending on operational conditions.

Interesting facts on the Ydro Process ®
The Ydro Process ® :
The most important control parameters for this method are: ORP (Oxidation
Reduction Potential), Dissolved Oxygen, degree of hydrolysis, Intracellular ATP
(measure of active biomass) and Extracellular ATP (released from dead
microorganisms) and Total ATP.
All technical documents follow our products i.e. MSDS, Biodegrability
certificate.
The Ydro Process ® is currently applied at more than 100 municipal
wastewater treatment plants in Europe and Asia and more than 15 large scale
and multinational industries.
The total current elimination of sludge with the use of The Ydro Process ® is
900 tons per day (ca a Population Equivalent of 6.000.000).

DECLARATION OF THE OPERATORS (PUBLIC
CORPORATION OF WATER AND WASTEWATER)
During the period of time between 15/03/2013 -
4/12/2013 it was verified that:
• There was an increased consumption of
organic load in the biological stage (aeration
tanks), with the suspended solids (MLSS)
remaining constant at a concentration of 3.500 –
4.000 mg/lt.
• Zero excess sludge was produced (EWC code
19 08 05), while during the same period of time
and at a conventional operation without the
application of bioaugmentation 4.800 tonnes
(mean average daily production 20 tonnes/day)
of excess sludge would have been produced.
The WWTP of Veria also processes external
sewage sludge produced from other municipal
sewage treatment plants. The following table
shows the quantities and origin of the sludge
processed.
