maximize plant performance
………………….TO A BRIGHTER FUTURE – WITH BIOGAS
(First prototype)
CAMBI THP PROCESS
BIOGAS PRODUCTION
“
The Dublin THP digestion plant ... can produce 3.5m³/day of biogas per m³
of digester capacity, which is 350% of the normal situation.”
Dublin, Ireland
Conventional treatment
CAMBI THP
CAMBI SIGNIFICANTLY REDUCES CARBON FOOTPRINT
”… installation of
anaerobic digestion …
significantly reduces
carbon foot print,
especially if
dewaterability is
improved” (Auty and
Blake, 2008, Barber,
2009)
“… [The] thermal
hydrolysis pretreatment
system at …
Davyhulme … will
reduce [United
Utilities’] carbon
footprint by 8% - the
equivalent of removing
270,000 cars off the
road for 30 years.”,
March-April 2009,

Benefits from the Cambi process
• Higher breakdown of material - produces more biogas
• Higher dewaterability – less cake with higher fertilizer value
• Higher digester load – smaller plant – smaller investment
• Sterilized sludge – can be spread on farmland

Scope of work- Consortium
•
Develop and modernize the sludge treatment systems at Vilnius Waste
Water Treatment Plant (WWTP)
•
Sludge thickening, digestion, sludge dewatering and low-temperature
drying as well as the utilization of the produced biogas in a combined
heat and power station.
•
After modernisation, plant will treat sludge from Vilnius WWTP and
surrounding water treatments plants
•
New sludge treatment system will be integrated in existing buildings
•
Turn Key delivery
Scope of work - Cambi
Turn key supply of Thermal Hydrolysis Plant (THP) which includes:
•
Thermal Hydrolysis Plant (THP)
– 1 pulper, 5 reactors, 1 flashtank and integrated control system
•
3 sludge coolers
– Heat exchanger and fin-fan coolers
•
Design and engineering related to the supplied plant
•
Installation of supplied equipment
•
Commissioning of all supplied plant on water
•
Training of operators
•
Operating and maintenance manual
THP-plant
Sludge coolers
Experience from cooperation with Lithuanian companies
•
Local company (RIFAS) is used for detailed design and installation of Control
system and MCC.
– Experience so far is good. (We do not know the conclusion until the plant has
started.)
– Communication might sometimes be challenging due to missing English skills
among some of the employees.
•
Local site representative hired through company Evikta
– Evikta was engaged by WTE for construction application process
– Experience is good
– He is fluent in Lithuanian and English
– Knowledge about local regulations
– Personal/company authorisation is required for approval of installation work
– Evikta is also used for minor mechanical modifications. Experience is good
with respect to quality and costs.
Experience from cooperation with Innovation Norway
• Innovation Norway was used for engaging the site representative
• Suggested potential companies that could offer the site
representative service in addition to evaluation of companies
suggested by Cambi.
• Prepared an evaluation of potential candidates
• Support during interwiev
• Support for writing the contract
Challenges related to the project in Vilnius
• Process for construction application
– Detailed engineering (Technical design) had to be
completed for construction application.
– A Lithuanian company (Evikta) prepared the
documentation for the application.
– 5 months approval period for evaluation of the
application for Litianianian authorities was indcated
at project start.
– The evaluation period was extended due to internal
processes inside Lithuanian authorities
Future possibilities
• Sludge centers
• Biowaste plants
• Farm residuals
