INDUSTRIAL SEWAGE
Horizontal industrial sewage storage tanks

Industrial sewage is generated during technological processes in numerous types of sectors. In order to assess its harmfulness, one has to know not only the composition of general sewage drained from the entire industrial plant, but also the composition of sewage streams drained from particular production departments. The knowledge of quantitative and qualitative parameters of sewage allows for assessment of a necessary degree of treatment, for which drainage of the sewage into a natural reservoir will not cause water quality to deteriorate. It would be desirable to obtain better quality of sewage than that of water in a reservoir. On the other hand, there is economically specified minimum that has to be assumed in order not to increase costs of a plant and to make the price of a product competitive as compared to global prices. The problem of sewage is particularly seen in coke plants, petrochemical plants, tanneries, cellulose plants, dairies and sugar production plants. Untreated sewage from such plants pose a high risk for natural reservoirs.

In this case, an ideal solution would be to use ZH type cylindrical tanks manufactured by Trokotex and equipped with two integrated supports or a tank with a single integrated continuous support made of GRP.

Industrial sewage storage tanks are used for contact with sewage, water, aqueous solutions of chemical with a wide range of pH, organic liquids and food preparations. An industrial tank can be used for medium with maximum temperature of up to 140°C.

We select materials for every equipment, considering its specific operating parameters such as type of a medium, temperature and place of installation.

Polyester and glass laminate has a lot of advantages, which make it possible for our tanks to compete with PE or P tanks:

 

  • light structure – possibility of installation on higher storeys of a building,
  • excellent chemical resistance of materials,
  • resistance to weather conditions such as humidity, UV radiation

Apart from standard equipment recommended for tanks used for storage of sewage, we also recommend the following options:

 

  • liquid level gauges
  • breathing valves
  • GRP/AR steel ladders (internal and external)
  • service platforms (enabling maintenance and operation of the equipment)

A tank can be of any length, which is restricted only to due transportation.

As every tank is delivered as tailored, distribution and size of connections (basic stub pipes and nozzles, manholes, thread connections) can be agreed and will not affect the price of a finished tank.

Characteristics of tanks:

  • Each product is subject to detailed tests performed in a company test laboratory.
  • Resistance of chemical substances and mechanical strength of our products is confirmed by test laboratories accredited by the Technical Supervision Office.
  • For every tank a passport is issued including, among others, the following data: technical data, technical drawings, certificates, results of laboratory tests, a protocol of acceptance by UDT and KJ.
  • In order to facilitate design works, complete drawings of our products may be sent in *.dwg formats.
  • The company renders counselling and training services at a customer’s premises with respect to use of our products.
