Dosing systems

Carbon Source Dosing System
Dosing Unit - Ex Proof
Filling Arrangement

Supplemental Carbon addition in denitrification systems

Increasing nitrate discharge values induce operators of waste water treatment plants to use carbon dosing technology to ensure observance of limit values and efficiency of effluent treatment units.

Supplemental of diverse C source substrates expands biomass´ activity respectively excludes the lack of nutrient by operational disturbance or shutdown during weekends.

Size of operating unit and choice of substrate is determined by waste water treatment plant.

Possible substrates are acetic acid, glucose etc. without any ex-proof requirements. In case of non observing limit values, methanol and ethanol feeding is appropriate to increase denitrification rate. But if the substrate is overfed, it will not be completely consumed by the biological process which will result in elevated effluent biochemical oxygen demand concentrations.

Our dosing units allow a precise control of chemical dosage, that helps to minimize chemical costs.

Chemical storage tanks

Officially Certified Tank with Filling Arrangement
Tank Transport on Low Bed Truck

Officially certified by IFBT

As a company authorized according to:

  • § 19 l of the Water Resource Law
  • the Regulation on Flammable Liquids(vbf)

we are entitled to manufacture storage, treatment and dosing systems of waterendangering substances.

Our production line is subject to the external quality assurance supervision by the Technical Control Association of Hesse - Germany.

All tanks are custom-made. The storage capacity ranges from 0,1 – 50 m³.

For approved storage media, see at latest storage media list, permitted by “Institute of Bautechnik Berlin (IFBT)”.

LIKUSTA certificate number of IFBT is Z-40.21-63.

For your convenience, we also may organize the transport / shipping to your construction at site – also abroad. Alternatively we also may weld individual tanks on site.

Plastics technology

Plastic Tank Production
Tank Production

Waste gas treatment and odour control systems.

The use of plastic materials for plants and tanks, etc. is contrary to steel constructions a great long-term and cost saving alternative. Due to progress and innovative improvements of thermoplastic qualities and the optimization of technical processes, plastic materials are the choice, whenever aggressive media are involved in the process.

Our product range at a glance:

  • Tank and apparatus construction
  • Pipework construction
  • Certified, approved tanks for water endangering substances
  • Heated and insulated supply and storage tanks
  • Fittings for piping systems
  • Butterfly valves and duct systems
  • Plastic lining
  • Mounting skids for dosing pumps/devices
  • Flotation tanks
  • Agitated tanks
  • Multi-chambered tanks for polymer facilities
  • Surge-tanks for swimming pools

Tanks and apparatuses made of following materials:

  • Polyethylene (PE)
  • Polypropylene (PP, PPs, PPH)
  • Polyvinylchloride (PVC)
  • Polyvinylideneflouride (PVDF)
  • Fiberglass (FRP)

Electrically Conductive Materials like:

  • PPs-EL
  • PE-EL

Tanks are available in round, square, vertical and horizontal designs.All custom made and certified by the external quality control of Technical Control Association of Hesse Germany (TUEV).

Our department for construction and development is always up to date and knows the latest technological developments.

CO2 degassers

Water treatment

LIKUSTA desorption facilities are used as mechanical-physical deacidification facilities in waterworks for the reduction of CO2 , for adjusting the pH value or for the removal of toxic and/or odorous smells.

Materials: : PE, PP

We offer the following types of facilities:

  • LIKUSTA type KVR cylindrical, round, upright, as counterflow column with bulk packaging materials
  • LIKUSTA type KRR rectangular, upright, as counterflow column with packing material
  • LIKUSTA type FBB rectangular as flat bottom degasser (very usefull in case of limited space;height of the device 1,5 - 2m)
