Zakres prac

Our client in this case was a company located in Lithuania, dealing with the distribution of various types of cereals. The project was implemented thanks to our representative in Lithuania, UAB Prespa.

 

This is our first project, delivery and installation carried out entirely by Ecol-Unicon outside Poland.

It represents a milestone in the development of the company’s activities on foreign markets, as we have already delivered not only the product itself, but the same range of services as on domestic territory, and the assembly itself took us only two days.

 

The tank measures 10m x 6m, with a capacity of 174.5 m3. Inside, it is divided into 2 parts by a wall that acts as an overflow baffle. Thanks to the baffle, the larger parts that enter the tank are retained in the first chamber, then the water overflows into the second chamber, from which it is pumped out through pumps located on the tank lid.

Further success in Lithuania. Together with strategic partner Prespa, Ecol-Unicon was honored to supply a brand new rainwater treatment line for Boar Crossing between Lithuania and Belarus. Construction works should be ended within the next few months but three sets of settling tanks and high-efficiency separators are ready to serve with good faith and fidelity to protecting the environment.

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

Customer needs

The client struggled with the excessive emission of odour and toxic substances from the newly created sanitary sewage network, including as part of the project “Organizing the water and sewage management of the Słupia and Łupawa rivers in the Sierakowice Agglomeration” and “Construction of a sewage system with connections and sewage pumping stations in the villages of Mściszewice, Węsiory, Kistowo, Skoczkowo, Bukowa Góra and Żakowo in the Sulęczyno commune”.

Applied solutions

Over 100 pcs of EMF-600/570/CH sub-manhole filters with active carbon filling. Additionally, a sublimation layer was used to increase the effectiveness of removing odours.
