Water and Sludge Treatment Plants NO COMPROMISE QUALITY DRIVES TO OUTSTANDING PERFORMANCES! 1 A BIT OF HISTORY Tecnoidea Impianti (in short T.I.) was born at the beginning of 80s as sales structure becoming later a manufacturing
- Tecnoidea Impianti (in short T.I.) was born at the beginning of 80s as sales structure becoming later a
manufacturing company where all main devices and components were self-engineered.
- From 1985 to the beginning of 90s the main sector covered by T.I. was the stone processing industry
(marble and granites) with small-medium size WTP and plate press, mainly installed in Italy and neighboring countries, in India, in North-Africa and South-America countries.
- During 90s T.I. increase the production to complete a full set of machines for quarries and aggregates
field and started to sell turn-key plants all over the word.
- In the same years Abra Pompe was based; such sister company (sharing the some T.I. ownership)
design and manufactures centrifugal pumps with abrasion resistant coatings.
- In the following years (1995 – 2015), the acquired know-how, together with the expansion of the
company personnel and skills, allowed T.I. to penetrate other industrial fields as ceramic, concrete, drilling, tunneling, soil remediation and all the sector involving wet process with mineral particles.
- Tecnoidea Impianti today can list important references with approx. 3’000 installations worldwide,
and can compete to the maximum level for treatment plants ranging from 1’000 l/min (approx. 270 gall/min) up to 20’000 l/min (5’200 gall/min) of waste waters, and with automatic plate presses for sludge dehydration, having capacity from 0.1 to over 10.0 m3/cycle.
- All our activities are certified in compliance with ISO 9001 quality standard, and all the plants can be
engineered to fulfill any international requirements (CE , UL, CSA and all the needed certification).
- Giving priority to the projects success and to customer satisfaction, T.I. now proudly claim the total
absence of any litigation and legal dispute all around the world, an interesting result considering the installation of 4 plants per month (average figure: 2000 - 2016).

PROCESS OVERVIEW
At a first coarse level, the overall treatment process can be summarized with the following Block Flow diagram. Water clarification (1° Stage) Sludge dehydration (2° Stage)

Water Clarification CORE process
FLOCCULATION
Flocculation is the key process in the clarification stage. Suspended solids are chemically destabilized and forced to aggregate into bigger flocks thanks to the addition of a chemical solution (polymer based).

R&D - LABORATORY A KEY RESOURCE Laboratory tests are paramount to design the most efficient and reliable clarification and filtration process
Even if sludge and wate waters may be coarsely classified on an experience and empirical basis, each one has specific chemical and physical properties that generates clarification and dehydration different behaviours.

R&D - LABORATORY TEST TOOLS AND DEVICES
PILOT PLATE PRESS
Built as a scale reduction of a production plate press, and working at its nominal pressure, this device symulates the entire filtration process, allowing to cast an accurate prediction
- f the complete plant performances
Sludge solids gradation and physical conditions impact directly on filtration time. This test is capable of defining proper filtration time of customer’s sluge samples, that reflects on the correct press dimensioning. This way customer is safe that the selected press is:
- Large enougth to manage all the sludge production fulfilling the project specifications, avoiding the risk of
selecting a smaller and insufficient press
- Not larger than needed, allowing a cost saving in purchasement and maintenance phases
