2. Evaporation plants

3. Resin plants

For the agricultural and food fields, Tecam designs plants for treatment of primary and waste water and for depuration and valorisation of digestate from biomass plants.

Tecam designs systems that allows to recycle the water and recover by-products (for example juices, fertilizers like ammonium sulfate, compost) with the aim to allow a rapid Return on Investment.

Biofuels

1. Biological plants

2. Physico-chemical plants

3. Evaporation plants

4. Membrane plants

5. Resin plants

A field strongly in increase that heads for the substitution of currently used fuel with those of new generation, therefore the field is in continuous evolution and search. Tecam previews technologies that know to remain at par with the field development, previews to invest on the following technologies:

  • regenerable resins concur the purification of the crude biodiesel without water employment in the process of production of the biofuel.
  • Biogas recovery
  • Discharge treatment with biological plants like UASB
  • “zero discharge” plants
  • Evaporation treatment plant

Ceramics and glass

1. Physico-chemical plants

2. Membrane plants

3. Vacuum filtration plants

4. Resin plants

By means of techniques of filtration in continuous combined with physico-chemical treatments it is possible to obtain:

  • partial or total recovery of treated water;
  • effluent discharge in compliance with the national law limits.

Chemical and pharmaceutical

1. Biological plants

2. Physico-chemical plants

3. Evaporation plants

4. Membrane plants

5. Resin plants

  • Softening
  • Demineralization
  • Processes water recycling
  • Metals and nitrates removal
  • Arsenic removal

6. Recovery of the process solutions

In the chemical and pharmaceutical industry water is used not only like solvent, but also like ingredient in chemical formulations: all the process solutions consider the need of an high quality water for this production cycle. The main technologies used in systems for treatment of chemical and pharmaceutical industry water are:

  • Resin or reverse osmosis for softening or demineralization of primary water, in particular for ultrapure water production;
  • physico-chemical, in continuous and discontinuous (or “batch”), for heavy metals removal;
  • ion exchange resins for working water recycling;
  • resin and ultrafiltration for recovery of solutions;
  • evaporation and crystallization for pollutants concentrations.

Landfill leachate and organic waste

Bacino di lagunaggio del percolatoLandfill leachate is a contaminated liquid that can have physico-chemical qualities variable according the kind of waste disposed and of landfill characteristics. In general, landfill leachate contains heavy metals, COD (in concentrations until to 30.000 mg/l), chlorides, sulphates and other pollutants as nitrogen, nitrates, ammonia, boron. For leachate depuration Tecam suggests high energy efficiency evaporation plants – in particular machines that use as energy sources biogas produced by waste or cool water of cogeneration groups – usually in combination with membrane plants (reverse osmosis and ultrafiltration) and resin plants. Between treatment technologies applicable to leachate there is the UASB (Upflow Anaerobic Sludge Blanket), that is able to combine to water depuration its valorization, by biogas generation.

Mechanical and iron working

1. Chemical-physical plants

2. Evaporation plants

3. Membrane plants

4. Resin plants

5. “Zero discharge” plants

6. Existing plants Restoration

7. Recovery of the process solutions

8. Supervision control

9. Turnkey supply

In order to resolve the typical problems of the mechanical field, in the discharges of which it finds the presence of metals, alkaline substances, surface-actives, oils, greases (emulsifying agents and not), etc and of the iron and steel field, where instead suspended solids, metals and thermal pollution appear, Tecam offers specific proposes inspired to logic of the minimization of the discharges through waters recycle.

Considered the presence of toxic substances for the environment, the idea is that one to obtain, when it is possible, conditions of ” zero discharge”; for this purpose TECAM plans traditional plants and treatment plants with water and products recovery, privileging these last ones.

In particular, in the field of iron and steel industry it points to the total recovery of the water (to restart the process) and of the metallic scale (to bring back in foundry).

Painting and varnishing

1. Chemical-physical plants

2. Evaporation plants

3. Membrane plants

4. Resin plants

The discharge produced from the field of the painting and varnishing industry are characterized from pollution from metals, phosphates, alkaline and acid solutions, surface-active, oils and organic substances.
The plants that Tecam realizes can achieve three levels of results:

  • chemical-physical plant with nonreturnable discharge (within the law limits)
  • integrate plants with centrifugal separators and/or ultrafiltration plants degrease baths regeneration and for the desludge of the phosphatizing baths
  • plants tending to the ” zero discharge” by means of coupling of different technologies, as evaporation, ion exchange, filtration.

Paper and wood

5. Evaporation plants

Tecam is investing his resources in the installation of biological plants with anaerobic techniques and with the use of granular sludge. Systems like UASB, IC, EGSB are from decades employed with optimal performances in fields like the paper industry characterized from effluent rich of amids, it is having a COD of approximately 2000-5000 mg/l.

This kind of plants can be employed also up stream of an existing aerobic plant and concur therefore to economic return thanks to reduction of excess sludge and power consumptions by valorization of the biogas produced.

Petrochemical

3. Evaporation plants

4. Membrane plants

5. Resin plants

Tecam has put right of compact plant solutions which can be easy integrated in a context where the effluents to treat are of various species. Moreover it has studied sections of mobile evaporation easy to install that they do not need a place of installation of the plant inside the factory, since it is equipped of its own structure of control. Compact biological plants can be installed in such contexts, taking advantage of several techniques of treatment.

Plating and microelectronics

1. Biological plants

2. Chemical-physical plants

3. Evaporation plants

4. Membrane plants

5. Resin plants

  • Softening
  • Demineralization
  • Metals and nitrates removal
  • Boron and arsenic removal

6. “Zero discharge” plants

7. Restoration of existing plants

8. Recovery of the process solutions

For plating and microelectronics industries Tecam studied solutions aimed to problems of discharge characterized from the presence of metals in solution, acids and bases, surface-actives, cyanides, etc. The goal is the minimization of water discharges until, when possible, “zero liquid discharge”.  recovery of the chromium plating solutions, nickeling, galvanizing, green coppering etc can therefore be realized.

Several plants solutions aimed at the several problematic, than Tecam realizes for the plating and microelectronics industry, are the following:

  • “zero discharge” plants that use different technologies in order to obtain a total water recycling;
  • treatment of primary water with resin plants (softeners, demineralizers) or with reverse osmosis plants, in particular for microelectronics for ultrapure water production;
  • treatment of waste waters with physico-chemical treatment plants, in continuous, and discontinuous (or “Batch”);
  • working water recycling with ion exchange plants;
  • solutions recovery with resins, ultrafiltration, electrodialysis, evaporation and concentration plants.

Printing, graphic and photographic

1. Evaporation plants

2. Resin plants

3. Biological plants

The discharges produced from the flexo – graphic printing, rotogravure graphic and offset, have elevated concentrations of sospende solids, organic substances of various nature, solvents, ammonia nitrogen. Traditional chemical -physical treatment plants, ionic exchange resins, etc do not concur to obtain effluent with suitable characteristics for the discharge in superficial waters or the public sewage system, neither recyclable for internal uses in the plant.

Tecam has developed specific treatment processes for this tipology of effluent, that concur to bring the polluting substances concentrations down within the limits of law consented for the discharge or in alternative for the recycle.
Plants work completely in automatic and are of modular type, in order to render their application extremely flexible according to the daily volume to treat, of the pollution degree of effluents and from the final destiny of the effluent (discharge or recycle).

The main typology of plant, often combined to each other, than Tecam realizes for this industrial field are the following:

  • evaporation plants
  • resin plants
  • biological plants
  • continuous filtration for the removal of suspended solid

Soil remediation

evaporatore-3600Remediation of a contaminated soil can be made through aspiration of polluted liquids from it or, if the pollutants reach very high concentration levels, removal and washing of it. In either case is necessary a treatment of wastewater: in the first case in situ, in the second case in specific plants near specialized companies. For removal of boron, arsenic and heavy metals, wastewater has to be treated in:

1. Physico-chemical plants

2. Resins plants

If it is contaminated from organic compounds, in:

3. Biological plants

4. Activated carbon plants

The parameter for the choice of technologies for in situ treatment is the time necessary for soil remediation. If it has to prolong for years, fixed installations are more advisable. For recurring or temporary interventions, the best solution is a mobile unit.
