Improve the performance and safety of your facilities with the EXPRESS DRAINAGE SOLUTIONS, NAIROBI, KENYA range of water treatment chemicals.

EXPRESS DRAINAGE SOLUTIONS, NAIROBI, KENYA water treatment chemicals range includes both organic and inorganic chemicals formulated to meet the individual specifications of customers in the industrial and municipal sectors:

  • Physical pre-treatment of water: settling, filtration, etc.
  • Physicochemical pre-treatment of water: reverse osmosis, resins, etc.
  • Treatment of energy carrying fluids: cooling towers, boilers, etc.
  • Drinking water productionrocess water production   
  • Effluent and sludge treatment, etc.

Antifoams; Antifoam blends contain oils combined with small amounts of silica. They break down foam thanks to two of silicone properties: incompatibility with aqueous systems and ease of spreading. Antifoam compounds are available either as powder or as an emulsion of the pure product.
Coagulants;  When referring to coagulants, positive ions with high valence are preferred. Generally aluminium and iron are applied, Aluminium sulphate and iron as either Ferrous (III) Chloride or Ferrous (III) Sulphate.
Corrosion inhibitors; Corrosion is a general term that indicates the conversion of a metal into a soluble compound. Corrosion can lead to failure of critical parts of boiler systems, deposition of corrosion products in critical heat exchange areas, and overall efficiency loss. Phosphate, molybdate, calcium, zinc or magnesium, silicate, phosphates, morpholine, hydrazine, salts of dicyclohexylamine, cyclohexylamine and hexamethylene-amine.
Disinfectants;    Disinfectants kill present unwanted microorganisms in water. There are various different types of disinfectants; Chlorine is an important chemical in water purification, in disinfectants, Calcium hypochlorite; Hypochlorite is applied in the same way as chlorine.
Flocculants; To promote the formation of flocs in water that contains suspended solids polymer flocculants (polyelectrolytes) are applied to promote bonds formation between particles. There can be several charges on one flocculent. There are cationic polymers, based on nitrogen, anionic polymers, based on carboxylate ions and poly-ampholytes, which carry both positive and negative charges.
Neutralizing agents (alkalinity control); In order to neutralize acids and basics we use either sodium hydroxide solution (NaOH), calcium carbonate, or lime suspension (Ca(OH)2) to increase pH levels. We use diluted sulphuric acid (H2SO4) or diluted hydrochloric acid (HCl) to decline pH levels.
Resin cleaners; Ion exchange resins need to be regenerated after application, after that, they can be reused. Chemicals that are used are for instance sodium chloride, potassium chloride, citric acid and chlorine dioxide.
