Chemical Additives Used In Wastewater Treatment

 Beyond planning and construction of plants, EnvoTech LTD offers chemical additives for wastewater treatment such as: anionic or cationic polymers - granular form, aluminium chloride, sodium hidroxide and others widely used in wastewater treatment plants.
FlOCCULANTS (POLYMERS):

Polyelectrolite Cationic Polyacrylamide

It can be used in pre-disposal of sludges as thickener and separation processes of wastewater from manufacturing foods, alcohol and paper, city wastewater treatment plants, beer factory, sugar manufacturing and deal with wastewater with high content of organic substance, wastewater from textile and other industries. In addition, it can also be used as chemical assistant such as thickening agent of oil field acidification and as enchancer in paper manufacturing.
We offer (sell) cationic polymer (granular form) to wholesale dealers and retail end user. Please do enquiry for price and details.

    Anionic Polyacrylamide

    Anionic Polyacrylamide is used for water treatment, mining and paper mills and others.

    Non-ionic Polyacrylamide

    When Ph of suspending polluted water is less than 7, it is suitable to adopt non-ionic polyacrylamide as flocculating agent and polyacrilamide takes function of bridging at the time to make suspended particle become flocculating precipitate and realize the aim of purifying wastewater. It is used in purification of city water, when it is combined to be used with imorganic flocculating agent, there will be a better effect for water disposal.
