Ochsmann Chemie offers process water chemicals for all areas of water treatment, from water treatment and fresh water conditioning to process water and industrial water treatment through to waste water and sewage water treatment plant applications.

Regionally different water compositions are a challenge for every industrial plant that relies on the use of water. Depending on the nature of the water, the following phenomena can be found:

  • Deposits from lime, suspended substances, corrosion products
  • Corrosion of metals (steel, copper, aluminium, etc.)
  • Biological growth by slime-forming bacteria

When selecting the optimal strategy to avoid these problems and to avoid their harmful effects as far as possible, a closer look at the water composition must be taken. The following parameters, among others, must be observed here:

  • pH value
  • Water hardness (sum of Ca and Mg)
  • Acid capacity (buffer capacity)
  • Calcium/Carbonic Acid balance
  • Saturation Index
  • Salinity
  • organic substances

Ochsmann products offer a wide range of protection against water-related problems in cooling/heating circuits, in waste water treatment and in the drinking water network.

Ochsmann Chemie GmbH has been active in the field of chemical water treatment since 1993.

We are specialised in treatment of:

  • Drinking Water
  • Cooling Water
  • Feedwater and Boiler Water
  • Industrial Water
  • Water for Emergency Supplies

The aim of any treatment is to protect the systems against corrosion and deposits as well as to optimize the water quality. In this respect, Ochsmann Chemie has both the necessary specialist knowledge and experience, as well as the corresponding product range, in order to adapt the water quality to the respective application in the best possible way. At the same time, we are continuously working on the development of new techniques to minimise the use of chemicals and to optimise the treatment ecologically and economically. Tailor-made solutions are developed for every application.

Other areas of application for Ochsmann chemicals include wastewater treatment, dust control and dump sealing.

One of the main reasons for deposits is the well-known lime. This is a reaction in the water-carrying pipe, the so-called limescale:

  • Ca2+ + 2 HCO3– => CaCO3 + CO2 + H2O

This precipitation reaction depends on several factors:

  • the pH value,
  • the carbonate hardness and
  • the temperature

To avoid this type of deposit, Ochsmann products can be added to the water to simply lower the pH in the water system or to perform complex softening. The means of choice depends on the local conditions.

We are happy to help.

According to DIN EN ISO 8044, corrosion is defined as “physicochemical interaction between a metal and its environment.” It has many different causes. The most common causes of corrosion in the operational process and in water circuits are:

  • A pH value that is too low
  • Water is too soft
  • Excessive salt content
  • The interaction of different materials within a process
  • Temperature
  • Free carbonic acid
  • Organic substances
  • Deposits (e.g. due to carbonate hardness)
  • Microbiology

Due to the large number of corrosion factors, the solution approaches are also diverse. It is not uncommon for combination solutions to be used in order to use synergy effects and to compensate for weaknesses in the individual products.

Within the group of corrosion inhibitors, individual products can be differentiated according to their mode of action:

  • Interfacial inhibitors
    This includes, among others, phosphates and zinc products. ….
  • Electrolyte film inhibitors
    Electrolyte film inhibitors including amines and triazoles. …
  • Membrane inhibitors
    The main representatives of membrane inhibitors are phosphonates.

In order to avoid or at least reduce signs of corrosion and thus avoid high repair costs, Ochsmann Chemie offers a wide range of process chemicals for optimising the pH value as well as biocides, bio-dispersants and special corrosion inhibitors for use in the areas of cooling water, service water and boiler water as well as use in drinking water supply.

The prerequisite for the development of significant biological pollution in water is the combination of water with nutrients, oxygen and optimal temperatures. Phosphorus, nitrogen and organic substances are particularly important for the supply of nutrients. The optimum growth temperature is between 20°C and 40°C.

From many points of view, the avoidance of biological pollution in water cycles is advisable. The harmful effects of the biological population, which mostly consists of bacteria, are manifold:

  • Slime-forming bacteria lead in particular to blockages and corrosion
  • Sulphate-reducing bacteria increase corrosion and are mostly responsible for odour formation
  • Nitrifying and denitrifying bacteria can cause pitting, some of which is considerable
  • Legionellae represent a health hazard for people

In order to avoid biological contamination, you can, for example, reduce the input of nutrients into the water system (water treatment and purification) and constructively ensure that no growth zones arise (e.g. by avoiding so-called dead zones). It is not always possible to implement this and therefore biological pollution in the water circuits can be observed on a regular basis. Ongoing analytical support (germ counts and legionella tests), as offered by Ochsmann Chemie to its customers, shows when the biological load on individual systems is too high and countermeasures need to be taken. Here you can either carry out mechanical cleaning or fight the bacteria in situ with biocides.

Ochsmann Chemie offers a wide range of products for such puposes. Feel free to contact us.
