The management of water resources is one of the major challenges we will be facing over next few decades. The growth in urban development, together with industrialisation and the development of irrigation are increasing the demand for water. BHT’s range of flocculants and coagulants covers all type of market requirements. These products have been approved by authorities for use within the scope of established standards. BHT has a range of polymers which suit from production of drinking water to sludge dewatering. To meet the needs of this ever-growing market, we have a product range of more than 1000 organic coagulants and flocculants.

Increased paper and water recycling practices place a heavier burden on improvement of chemistries used to maintain paper and board quality. BHT’s Polymers for Paper – BHT supplies products specially designed to meet pulp and paper industry needs. We provide not only process chemicals for on-machine application but also flocculants and coagulants for effluent treatment plants. From the highest quality printing paper grade to the stiffest board made from recycled waste paper, BHT has specific products to improve the manufacturing process. BHT supplies most of the synthetic coagulants and flocculants useful to the paper processes covering a wide range of formulations: cationic, anionic, amphoteric, with various molecular weights, in solid, liquid or emulsion phases.
Water is essential to the paper industry, where it is used to transport cellulosic fibers and mix them with other components. Polyacrylamides enhance productivity, retention and drainage. Coagulants act as fixative for various chemicals such as dyes and sizing agents, charge neutralization for pitch and cationic demand control. BHT supplies synthetic dry strength resins which are acrylamide based, glyoxalated or issued from Hofmann rearrangement. These resins, applied in the thick stock, imparts higher strength properties to paper & board, allows fiber substitution by lower quality grades or by fillers.
Polyacrylamide superabsorbents can absorb up to 400 times their weight in water, they are used for many applications such as reforestation, horticulture, landscaping and ornamentals. These products sold under the BHWRSORB tradename, increase the water holding capacity of soils for several years, reduce irrigation time and water usage, and decrease water and nutrients losses linked to leaching. Soluble polyacrylamide polymers are used to flocculate the irrigated soil thus improving water penetration and soil aeration while diminishing soil erosion. Polyacrylamide superabsorbents can absorb up to 400 times their weight in water.
PRODUCT LINE :
BHWRSORB – Increase the water and nutrient retention capacity of soil. These products, increase the water holding capacity of soils for several years, while reducing irrigation time, water usage, and water and nutrients losses linked to leaching.
BHBOND – Reduce erosion and crusting. Prevent the runoff of certain mineral fertilisers and of pesticide residues. BHBOND soluble polyacrylamide polymers are used to flocculate the irrigated soil thus improving water penetration and soil aeration and diminishing soil erosion.
BHPRINT textile thickeners are used in pigment, reactive and dispersed printing. They are available as standard inverse emulsions, dewatered inverse emulsions and powders. BHT also supplies textile auxiliaries used as antimigrants, dispersants, sizing and fixing agents.
BHT has a broad range of thickeners for pigment, disperse and reactive printing. These products make it possible to print very fine details and allow for improved color yield. The range is accompanied by fixatives, anti-migration agents and dispersants.
