The first such system in Poland

The ventilation, dust removal and deodorization system implemented for the Sorting Hall at the Solid Waste Utilization Plant in Tczew is the first such system in Poland, and probably even in Europe.

 

It all started with months of research conducted jointly with the Department of Toxicology of the Medical University of Gdańsk.

Air composition analyses were carried out in the Sorting Hall as well as on its roof, in a research model specially constructed for this purpose.

 

These studies, in addition to the precise determination of chemical compounds in the air, were designed to select the most effective active carbon mixture that would be used for the deodorization phase.

 

Signing of the Innovation Partnership agreement with town municipality of Tczew took place on April 7, 2017.

Assembly and tests

Wtedy właśnie rozpoczęła się druga faza projektu czyli montaż urządzeń. Koncepcja została przygotowana przez dr inż. Andrzeja Staniszewskiego. Zakładała montaż 3 niezależnych systemów, z których każdy składał się z systemu wentylacji, odpylania i dezodoryzacji.

Montaż zakończył się odbiorami oraz rozruchem urządzeń, który nastąpił 19 lipca. W tym samym dniu wykonano również badania tzw. zerowe wspólnie z GUMed. Cały projekt wszedł w ostatnią fazę, która skupi się na badaniach pozwalających na ostateczne dopasowanie mieszanki węgla aktywnego.

 

Ecol-Unicon, jako Generalny Wykonawca Inwestycji, do współpracy zaangażował partnerów: firmę SCROL, która realizowała montaż urządzeń oraz spółkę BIOPRO odpowiadającą  za realizację badań.

Technical description of the investment

The system consists of three independent systems and several stages of research and testing enabling individual adjustment of the system.

 

Technological solutions included in the ventilation, dust removal and deodorizing system:

  • Modernization of ventilation, carried out by the implementation of three independent systems, including a new system of channels ensuring at the same time effective collection and removal of dust and selected odorogenic substances, the total length of the channels is over 160m.
  • Dedusting devices – execution of 3 independent systems ensuring efficiency up to 60 000 m3/h.
  • Neutralization of odors and selected toxic substances – construction of three independent devices ensuring the removal of odors and toxic substances. After dedusting the polluted air from the hall, it is directed to the bed, where it is cleaned as it passes through a material that neutralizes odors and toxic substances. The flow of dust-free air is realized by blowers installed in the ventilation-dedusting-deodorization process line. The neutralizers are filled with two types of bed in a total amount of 36 m3

Applied solutions

  • renovation of the metal body (sandblasting, painting),
  • replacement of the entire facility equipment,
  • flowmeter chamber has been added,
  • connecting the facility to the monitoring system.

Applied solutions

The system includes:

 

  • 6 groups of tanks – 1720 m 3 in total, all with similar equipment
    and metering
  • valve with electric drive and radar water level measurement,
  • 2 valves (supply and emptying of tanks) with electric drives,
  • separator with a bypass and a tank for oil derivatives,
  • hydrant feed pump,
  • meter of water quality and conductivity
  • water level sensors in tanks

The scope of work included:

 

  1. Development of a local precipitation model, local reference hyetograms and computer hydrodynamic models.
  2. Development of complete project documentation and obtaining the necessary arrangements, decisions, permits for the performance of the contract.
  3. Delivery and installation of the Bumerang Smart software along with the necessary equipment for its operation, controlling water retention rainfall:
     

    • electrically controlled drives on gate valves
    • quality monitoring of retained rainwater
    • network controlled valves
    • monitoring of the filling of the cross-sections of the rainwater drainage system below the tanks
    • installation of a rain gauge and a weather forecast monitoring subsystem
  4. Execution of construction works
  5. System implementation and user training
  6. The system will control and optimize the operation of the retention reservoirs installed along the existing storm sewage collectors using the latest weather data and specially created models hydrodynamics.
