Quality Clean Water Is Essential for Healthy Living
and a Sustainable Environment
Waste Water Treatment for Municipalities and the Industrie
Our wastewater treatment technologies offer the solution to problems that industrial companies and municipalities have with their wastewater.
Together with our partners (over 30 years of experience) we offer sewage treatment plants worldwide to industrial and municipal customers.
In addition to the construction of complete sewage treatment plants for full and preliminary cleaning, we have carried out a number of extensions and renovations to existing wastewater treatment plants.
Every system concept is based on our experience and is constantly supplemented by the company's own research and development.
Our sewage treatment plants are designed and built according to the necessary requirements and needs for optimal use.
To do this, we apply all the necessary treatment steps, from pre-treatment to biological and chemical-physical cleaning to treatment of the waste water for internal or external reuse.
The sewage treatment plants, which we are continuously developing, have also been specially adapted for the African continent with its special conditions and different environmental influences.
We have specifically focused on 2 key areas:
1) The Waste Water Treatment and Waste Water Recycling of Municipalities and Cities
2) The Waste Water Treatment and Waste Water Recycling in the Industry and here in particular:
- metal and heavy metal industry
- chemical industry
- gas and oil industry
- mining
System 1: Activated Biological Sludge Reactor + ARS Reactor for Municipalities and Cities
technology consists of a mixing and equalizing tank, a biological reactor, an ARS reactor and a two-stage secondary treatment reactor.
We developed this technology ourselves and have often built it in various countries in Europe, America, Australia, Africa and Arabia.
Since this type is particularly suitable for weather conditions with hot, dry summers and winters with very heavy rainfall and hardly requires any maintenance.
The advantages are:
- Freely selectable, perfectly graded module sizes are combined in a space-saving and standardized way.
The arrangement and the rectangular shape of the individual reactors save until 30% investment costs
and 70% energy.
- Conception with minimized mechanical and electrical effort, clearly structured processes with fully
automatic control and central visualization on touch screens.
- The sludge age and thus the process stability is much higher than in conventional plants due to the
integrated ARS reactor with a 4 to 5 times higher concentration of suspended solids from mixed liquids
(MLSS).
- The technology has lower capital costs and requires a much smaller space with up to 50%
- Additional preliminary stages can be installed without any problems, so that it is no problem to purify
municipal and industrial wastewater together
- Subsequent stages can be added to increase the capacity without having to switch off the working Plant
System 2: Waste Water Treatments for the Industry
We offer “tailor-made” turnkey wastewater treatment plants for both pre-treatment and complete treatment of effluents up to internal reuse.
Proven cleaning processes are individually developed in the necessary cleaning stages, put together and used appropriately.
Since the wastewater content varies depending on the production process and contamination by heavy metals and other chemicals, there are a wide variety of technologies for cleaning wastewater.
Contaminants found in industrial wastewater from the steel, chemical, mining industries often include:
Organic impurities, which in most cases are expressed as sum parameters, such as:
-
AOX (Adsorbable Organic Halogen Compounds)
-
COD (Chemical Oxygen Demand)
-
TOC (Total Organic Carbon)
Specific organic impurities:
-
Aromatic hydrocarbons including BTEX: benzene, ethylbenzene, toluene and xylene
-
Halocarbons
-
Organo-metallic compounds (e.g. contain tin or mercury) derived from chemical synthesis processes pesticides and herbicides
Inorganic impurities:
-
heavy metals (Iron, zinc, copper, manganese, tin, chromium, cadmium, lead, mercury, uranium)
Due to the increasingly strict legislation on waste water quality, there is an urgent need to implement new, more efficient and cost-effective cleaning solutions.
Depending on the discharge limit values, the wastewater must meet specific specifications with regard to COD, TOC, AOX, pesticides and heavy metals, among other things.
Our sewage treatment plants are therefore designed according to these specified discharge limits in such a way that they reliably do not exceed these discharge limits, even in extreme cases.
We have adapted the following cleaning concepts for reliable cleaning of even chemically and biologically heavily polluted waste water, especially in the branches of industry that we specialize in:
-
Wastewater containing mineral oil is usually pre-cleaned with an oil separator.
Fats and oils can be separated from the waste water with the help of a flotation plant.
The addition of chemical substances for waste water treatment usually takes place in a combined CP or flotation plant.
-
There are various application methods to remove heavy metals, one of which is Ion Exchange Resins.
These can be used to remove heavy metals from industrial wastewater.
These chelating resins are used to remove heavy metals and work on the principle of complex formation.
The functional group of the resin is a ligand that forms a complex with the heavy metal cations, which can then be removed from the solution (transition metals).
-
by converting dissolved substances into undissolved substances and subsequent sedimentation or flocculation.
-
Ion exchanger for the selective removal of uranium Here, ions dissolved in the water can be removed by exchanging them for ions with the same charge, such as calcium.
Overview of the cleaning steps and procedures used:
Activated sludge process + ARS procedure, Sand trap, Sieving, Grease trap, Precipitation, Fixed-bed processes, Lamella separator, Flotation, Flocculation, Mixing and balancing reactors, Membrane filtration, MBR membrane bioreactor, Disinfection with UV, Chlorination
