Wastewater Treatment Plant for Deep-Cleaning of Wastewater Contaminated with Oil Products

Aprašymas:

An effective technology developed for cleaning water from hard-to-degrade toxic oil compounds uses the sorption capacity of a special sorbent and the oxidative potential of degrading microorganisms. The layer of microorganisms formed on particles of activated carbon creates a stable, resistant, and effective complex consisting of sorbent, microorganisms, and pollutants.

The plant operates under aerobic conditions, while the sorbent self-regenerates when dynamic equilibrium is reached, thus there is no need to replace it regularly. As the pollution of wastewater changes, the plant switches between absorption, biochemical degradation, and sorbent regeneration processes. 

The applications of the technology is continuously expanded to the treatment of other types of polluted waters, such as pharmaceutical and textile industries.

Research of the Properties and the Structure of Self-Compacting Concrete

Aprašymas:

Concrete and reinforced concrete constructions made out of this concrete have a non-porous, visually pleasing concrete surface.

This concrete does not require additional compaction; meanwhile, construction reinforcement can be highly dense. The use of such concrete in reinforced concrete factories allows maximum automation of the production process.

The developed technology allows to produce a concrete mix which is superior technologically, has the best physical and mechanical properties, and is the easiest to use. The spread of the concrete mix is less than 650 mm.

Novelty:

We expect this fluid concrete mix to replace around two thirds of the usual concrete mix in Europe over the next 10 years.

Ultra High Performance Fibre Concrete with Advanced Mechanical Properties and Durability

Aprašymas:

It has been proved that ultra high performance concrete can be prepared not only from expensive reactive powder but also from cheaper (local) materials.

Research has already found links between concrete’s properties and durability as well as identified its change patterns; the technology for achieving the optimum composition of the concrete as well as using it in a mixture has also been identified.

Novelty:

Ultra-high performance fibre reinforced concrete (UHPFRC) mixture with advanced mechanical and durability properties was created using ordinary mixer. Compressive strength varied  from 130 MPa (without micro steel fibres) up to 170 MPa (with 147 kg/m3 micro steel fibres). Flexural strength can be increased more than 5 times – from 6.9 MPa (without micro steel fibres) up to 36.2 MPa (with 147 kg/m3). Salt-scaling resistance at 40 cycles in 3% NaCl solution varied from 0.006 kg/m2 to 0.197 kg/m2.

Non-Autoclaved Aerated Concrete

Aprašymas:

The new aerated concrete composition allows to achieve highly stable properties of the concrete.

The proposed composition reduces the cost of the concrete thanks to using secondary raw materials.

Novelty:

The non-autoclaved aerated concrete based on the modified binding composition containing a supplementary cementitious material, reinforced with polypropylene fibers is characterized by the compressive strength of 2.0…3.0 MPa, with the density of 600…650 kg / m3. Pore size – 0.2-1.0 mm.

Cone Penetration System for Soil Exploration

Aprašymas:

To identify engineering geological conditions, physical-mechanical characteristics of the soil are needed. This type of information can be obtained after the soil engineering geological research.

Nowadays, fast and quite cheap soil research methods, which allow obtaining of all the information about engineering geological information, are widely spread. One of these methods is static probing or penetration.

IES research group is doing a research on creating an intelligent probe and integrating it with a management system.

Such system would allow to design and build bases of various buildings quicker, cheaper and more accurately.

Object Tracking and Security System without GPS

Aprašymas:

The device reacts to the movement and if the wood is moved, it sends an alarm message to the owner.

The path of a GSM device could be monitored by the PC after receiving alarm message.

After the storage place is found, the log could be located by using special equipment because of the hidden RFID and GSM device which will help you prove that the wood belongs to you.
