Emulsions and other waste water

...are by-products that often occur in large quantities during industrial production and processing. In other words: they are environmentally harmful industrial residues which must not be discharged into the sewage network or into surface water without prior treatment. Otherwise they would be a hazard to the ecosystem and to human health. This type of waste must be disposed of or treated at source according to the statutory requirements.

Application for industrial waste water

The effluent from many industrial processes consists of a mixture of oil and water in the form of a stable emulsion, in which tiny, finely dispersed oil particles are present in the aqueous phase. These cannot be separated solely by means of gravity, e.g., using a low-viscosity fluid separator or a coalescence separator. The BEKOSPLIT® system provides a reliable means of processing oil-contaminated, emulsified industrial effluent. By adding a natural high-alumina mineral, water-insoluble organic impurities – such as oils, vegetable an animal fats and a variety of solid contaminants – are removed from the waste water, and any existing heavy metals, dirt or paint particles are reliably absorbed.

FLEXIBLE SPLITTING AND TREATING = REUTILIZATION

Your 1st choice: BEKOSPLIT®

The BEKOSPLIT® unit is your guarantee for the safe and effective treatment of emulsion – be it for small or large capacities. BEKOSPLIT® emulsion splitting plants are available in different sizes; they are designed for reliable and low-maintenance operation. The independently operating splitting unit in combination with corresponding tank components allows you to choose the best possible configuration for your particular application.
The purification of waste water using the BEKOSPLIT® technique is particularly suitable for oil/water emulsions with concentrations of emulsified oil below 1%. The BEKOSPLIT® plant permits virtually waste-free and environmentally friendly operation, since the material of the spent filter cake can be reutilized.

THE BEKOSPLIT – PROCESS

The emulsions are conveyed to the primary feed tank via the patented pressure relief chamber (1). Here preliminary cleaning of the waste water takes places by gravitational separation, which permits separating the free oil parts (2), even with fluctuating feed quantities.

The oil discharge (3) is automatic and the liquid level states are monitored by the BEKO sensor system.

The specially developed capacitive electronic monitoring device is capable of distinguishing between air, oil and emulsion. Consequently, emulsion cannot get into the oil collector, and free oil parts cannot get into the oil collector, and free oil parts cannot enter the splitting process.

The waste water to be treated is pumped by a hose pump into the reaction chamber of the splitting unit.

The subsequent waste water treatment is fully automatic, starting with the addition of the bentonite splitting agent. This non-toxic, but highly effective emulsion splitting powder is stored in a metering unit (4), which releases the exact amount of powder to be stirred into the emulsion (5).

Splitting and separating of the emulsion are performed in a single sequence. The separated oil and dirt particles are encapsulated by the splitting agent and form macroflocs that can be filtered easily. The flocs flow through a discharge duct into the filter bags where they are retained (6).

The purified water can then be safely discharged into the industrial water or sewage network.

Compared with other methods, characterized by high maintenance and high costs, the BEKOSPLIT® system offers genuine advantages:

ADVANTAGES

Specially developed concept for oil-contaminated effluent

• Throughput of varying emulsion quantities without special adjustment

•  Combination with effective preseparation tank for the removal of free oils.

•  Very low splitting agent requirements

•  The patented pressure relief chamber ensures smooth waste water flow into the preseparator. This facilitates the separation of pure oil, reduces the consumption of splitting agent, and increases the service life of the filter.

•  Simple and reliable measurement of cloudiness

Filtration through bag filters

•  Low water content of filter residue due to large filter surface

•  The filter cake consists of a compact, non-leachable residue suitable for waste disposal

•  Low filter consumption owing to filtration through bag filters

•  Simple, fast filter replacement

Electronic monitoring of all operating states

•  Microprocessor control of sequences

•  Monitoring of splitting agent

•  Permanent monitoring of filters

•  Maintenance and alarm messages can be processed externally via signal outputs

•  The fully electronic control and monitoring system permits largely unsupervised operation. This saves labour costs.

Non-toxic, environmentally compatible splitting agent

•  No protective measures necessary for handling water-endangering substances

•  Simple reliable metering

•  No addition of auxiliary splitting substances required

•  The highly effective, broad-spectrum splitting agent makes continuous pH-value adjustment unnecessary. Chemicals are therefore not required

•  Adsorption is also effective for other substances contained in the waste water (dissolved hydrocarbons, heavy metals); after treatment of the clean water is normally not necessary

Full range of accessories and service option

•  Primary feed tank for collecting varying quantities of effluent

•  Drying rack for drying of spent filters: to reduce weight and thus save disposal costs

• Receiving troughs for installation according to the legal provisions

•  The BEKO inspection agreement offers a comprehensive service to ensure constant availability of your BEKOSPLIT® emulsion splitting plant

•  Full range analysis service.
