IMHOFF tanks
The Imhoff septic tanks are anaerobic units of primary treatment, consisting of a lower tank called "digester" and tan upper one "sedimenter". The branch enters the sedimentation compartment that is designed to retain solids and floating material, then enters in the lower tank (digester), through the opening on the bottom of the compartment. Digester and sedimenter are sized so that the first one has a biological stabilization of organic matter sedimented (fermentation and anaerobic digestion) and the second will create the necessary zone of calm that allows an eligible sedimentation of solids in wastewater. Periodically mineralized substances, sludge and floating substances, must be taken.

Septic tanks
The septic tanks are anaerobic units of primary treatment, in which is removed a portion of organic material and suspended solids. They are called septic tanks becouse are generated in an anaerobic fermentation, which is precisely a "septic" type. The septic tanks are appropriate only as an optional to a secondary treatment installation, but may be used alone only in cases of specific authorizations. The septic tanks and bicameral make a better performance primary treatment, as being composed of several compartments allow for a gradual clarification of the wastewater.  DegreaserDegreaser for residential, hotel and restaurant, similar activities (AE 50 liters).
Degreaser for restaurants, taverns, food preparation companies, villages, barracks, similar activities (30 liters AE)
Degreaser for hospital canteens served with meals, nursing homes served with meals prepared, similar activities (10 liters AE).
Active sludge
The active sludge plants are systems for biological treatment of biomass suspended for prolonged ventilation. They are called biological becouse the degradation of organic matter and part of the suspended solids in the slurry is effected by the action of bacteria feeding pollutants purifying the wastewater. The artificial aeration of the wastewater ensures the proliferation of those bacteria that form colonies "sludgeflakes" typical of suspended biomass. The active sludge plants are composed of two parts: the oxidation and sedimentation. The first is the oxidative phase of the wastewater: the sewage is subjected to an intensive treatment of artificial ventilation, in an environment so rich in oxygen start physical, chemical and especially biological that degrading the pollutants. The high microbial concentrations in the oxidation compartment, responsible for the purification of wastewater, is ensured by the continuous recirculation of activate sludge taken in the sedimentation compartment. In the sedimentation compartment, under a state of calm, occurs the separation and the precipitation of sludge which are recirculated in the oxidation compartment. The clarified and purified wastewater is sent to the next phase of treatment. Only the sludge produced in excess (excess sludge) must be periodically removed from the plant.  Purification unit

Equalizer
The equalizer is designed to equalize the hydraulic load and make more homogeneous as possible the load of polluting wastewater. Increases of load could cause serious consequences on the cleaning efficiency because the microorganisms are difficult to adapt to sudden environmental changes. The equalization compartment is advisable in all applications but becomes essential in cases where the variability of the scale and (as result) the pollution load is especially high. (see business, offices, bars, restaurants etc..). The Telcom equalizers are sized considering a production time of: 8 hours for business 16 hours for residential or similar activities.

Water tanks
Drinking water tanks, linear polyethylene, absolutely non-transparent (colored in mass for extrusion) in order to prevent (to 100%) the formation of algae, thus maintaining the perfect water potability and pleasantness.
 Vertical tanks
From 100 to 16000 liter, size 48x67 cm for 100 liter, 238x382 cm for 16000 liter.
 ShuttleFrom 1000 to 3000 liter, size 147x154 cm for 1000 liter, 308x198 cm for 3000 liter.
 Square tanks
From 100 to 1400 liter, size 58x52x52 cm for 100 litrer, 146x167x77 cm for 750 liter.
Inter tanks "Bunker"
The exceptional thickness and the very compact moleular distribution of used resins, allows an use even in critical conditions. The raw material (linear polyethylene) mass colored for extrusion and enriched with special additives gives to containers a high resistance to thermal degradation (-60 ° +80 ° C) and thus a barrier to aging. Used as reserves of drinking water for human consumption, for the collection of rainwater, waste water collection, storage of diesel and lubricating oil.
Bunker
From 500 to 10000 liter, size 94x87x98 for 500 liter, 230x225x310 cm for 10000 liter.
