Derypol, S.A. products

Our HIMOLOC products are flocculants where chemistry is art, to achieve the easiest to use polymers, the most respectful for the environment, exclusive, unique and different, the most efficient in many applications, innovative and sometimes magical.

The products of the Hygreen series were born with the aim of meeting the increasingly growing need for renewable, natural and environmentally friendly products. The aim of these products is to improve the performance of the treatments, reducing the environmental impact and the general costs derived from the same treatment.

Polidadmacs of different Molecular Weight They are acrylamide-free and comply with the requirements of the UNE:EN 1408:2008 standard, with regard to products used in the treatment of water intended for human consumption. Some of them have such a high Molecular Weight that they can successfully replace the use of classic polyacrylamides, with the advantage that, combined with aluminum salts, they leave a lower residual content of this metal compared to any other standard product.

Polyacrylamides with a residual monomer (acrylamide) content below the standard so that they can be used in highly efficient doses in compliance with current regulations (maximum residual acrylamide of 0.1 μg/L in the treated water).

High Molecular Weight CATIONIC polyacrylamides containing the special Derypol monomer (BZQ) to separate fats and oils, especially in flotation processes.

Very High Molecuar Weight CATIONIC polyacrylamides. Especially used in physical-chemical treatments and in sludge dewatering processes by centrifuges and screw presses.

High Molecular Weight and Cross-linked CATIONIC Polyacrylamides to increase sludge dryness in sludge dewatering systems, especially high speed centrifuges, obtaining solvent and surfactant free sludge, drastically reducing the emission of volatiles (VOC) into the air in Thermal Dryers and complying with regulations to use the final sludge for agricultural or land filling purposes.

High Molecular Weight ANIONIC and NON-IONIC polyacrylamides. Universal flocculants with great affinity to separate suspended solids. Some of them contain AMPS monomer performing in a wider pH range, improving their resistance to hydrolysis and facilitate their dissolution.

High Molecular Weight Amphoteric Polyacrylamides specially used in Physical-Chemical Treatments with lack of homogenization or where the quality of the residual water changes is frequent. Special synergy with the HYGREEN series of coagulants (tannin-based vegetable coagulants). Although these products have been recently developed, they are already successfully used in the dewatering of sludge in filter presses (avoiding the clogging of the fabrics) and in the waste water treatment in many industrial fields, especially when the oil and fat content is high.

High Molecular Weight acrylamide free Cationics polymers. Used in treatments or processes where strong cationic demand is required and/or where acrylamide-free processes are necessary.
