Summary

Summary: 
A Russian university develops innovative solutions in the field of wastewater treatment. The university has developed a water purification technology using innovative reagents-flocculants. Using them in the production and technological process will allow enterprises to reduce costs, energy intensity, and labor intensity of production. The university is looking for foreign partners to conclude a commercial agreement with technical assistance.

Description

Description: 

The developer of the technology is a research institute, which is
part of a multidisciplinary university from Russia. It was founded in 1916.
Water is an essential resource for many industries and serves as a source of life for all living beings. Therefore, thorough treatment of water and sewage is so necessary. There is a wide variety of soluble and insoluble pollutants, and therefore there is no universal way to neutralize and remove them. Therefore, for the implementation of sewage treatment processes, it is necessary to comply with various cleaning methods. One of the most popular methods in the world is mechanical. The method is used for the pre-treatment of water that flows to treatment facilities. As part of the process, the waters are not only prepared for further biological treatment but also purified from insoluble impurities. For such cleaning, several types of structures are used, including grates, primary settling tanks, sand traps, and septic tanks. This method is highly expensive and requires a long time for water purification.
Based on the world experience in water treatment, the university has developed an innovative solution. The use of flocculants is widespread for different kinds of purposes. However, there are still improvements to be made. For example, heavily contaminated effluents often require a preparatory stage of treatment before using of flocculants. As such, the galvanic industry has Cr-containing (chrome) effluent, and Cr has to be preliminarily transferred from a 6-valent state to 3-valent in order to use flocculants efficiently. The developed technology provides a flocculant that treats concentrated effluents with 6-valent Cr. The efficiency of this treatment is two orders of magnitude higher than the efficiency of widely used aluminum salts.
Another widely used preparatory stage is treatment with coagulants. The developed technology has an opportunity for effective treatment of industrial effluents and additional coagulants are unnecessary. It includes effluents containing high concentrations of magnesium, calcium, and iron. The developed compositions can be used for the treatment of concentrated city sewage.
Another option available for the developed technology is the preparation of drinking water. One of the developed variants of flocculant is efficient for processing water from humus. More importantly, the developed flocculant is much easier to remove after discoloration of water than most of the substances widely used for the same purpose.
Flocculants are based on block and graft copolymers of polysaccharides (starch, chitosan) with vinyl monomers of various molecular weights of natural and synthetic components. The developed product is multifunctional and can simultaneously perform the functions of a flocculant, a coagulant, and a sorbent since natural polysaccharides have functional groups in their composition, capable of sorbing not only suspended particles but also pollutants carrying a charge (metal ions). In addition, it is proposed to use the modernized "double additive method" in which the reagent carrying a charge opposite to the charge of reactants induced in the first stage is used in the second stage of waste treatment.
The Russian institute is looking for foreign partners from various fields of industry related to the use or treatment of water for concluding a commercial agreement with technical assistance. The institute is ready to sell the right to the technology and provide technical assistance, assistance in installing and configuring the technology, training personnel, etc.

Advantages & innovations

Cooperation plus value: 
- The technology has a lot of variations for different tasks set for the product: preparation of drinking water, treatment of industrial effluents or sewage. - Technology can be modified for obtaining of specific types of contaminants present in the effluent. Developed compositions of flocculants result in improved efficiency and ability to function at lower temperatures (down to 3°C). - All developed flocculants are eco-friendly and non-toxic.
