Integral Treatment of Leachate – TIL

Integral Treatment of Leachate, just as an industrial water treatment plant (WTP) aims to achieve, from sewage or mixed and through different physical, chemical and biotechnological methods, a water effluent of better characteristics of quality and quantity, on the certain parameters normalized basis.

In general, wastewater treatment plants treat wastewater locally, from the citizen consumption for the most part, as well as surface runoff drainage urbanized areas, in addition to water from small towns, through processes and treatments more or less standard and conventional. There are also WTPs are designed and built for large enterprises, which specializes in overall wastewater treatment.
TIL, instead, it is a new system, expandable by modules, getting to realize a comprehensive and compact structure with all the technological advances.

Asphalt irrigation

While this type of firm is being replaced by the hot mix asphalt over the years, is still used in addition to repair existing roads originally built with this technique, paving rural roads, rails services parallelogram alleles in major traffic routes and other traffic access limited volume and weight.

As it is not a manufactured and controlled centrally and then start work mix, but its most important feature is the “in situ” execution, the durability of these works will depend largely on the quality of the materials used, the embodiment:

  • Control of the emulsion temperature
  • Accuracy endowment arid surface
  • < p>

    Given these parameters without forgetting the climatic conditions that sometimes hinder the execution of these works, as well as having a team of professionals with proven experience, only you can successfully do this work with teams of execution as described below:

    Gravel machine
    • Opening and closing hatches to vary the width of lying with pneumatic drive, which optimizes the speed.
    • Gravel extraction system from proportional to Dump truck speed mechanical drive.
    • Bottom drawer for manual loading in repair operations.
    • Dump capacity of 18 cubic meters.

    Emulsion tank and ramp
    • Hydraulically width varying between 2.5 and 5 meters controlled from the truck.
    • Computerized support surface envelope which varies the speed of the emulsion pump, and therefore its flow.
    • Set ramp width.

    These teams, along with teams of compaction with the needs, make a team characterized by its high daily production and a high level of control which benefits the durability of the work.
