  • Closed circuit Water Treatment Chemicals

    The problems encountered in closed circuit systems are like those in open systems – corrosion, suspended solids, scale, and microbiological contamination. However, there are differences between the systems which require us to treat them in different ways. The fixed volume, low make-up of a closed system allows us to dose water treatment products at much higher levels than is possible in ...

  • The cheapest, simplest, (yet highly effective) solution to cooling tower drift

    The problems caused by water drift are numerous. The water usually contains treatment chemicals that are corrosive and damage paint on nearby equipment, buildings, automobiles, etc. In cold climates, the drift can cause dangerous icing on the roads and walkways. In some cases, the drift represents a significant loss of water, treatment chemicals or process heat. If nothing else, drift is nearly ...

  • Manufacturer of Water Treatment Chemicals and Water Additives

    Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels contaminants and ...

  • The application of potassium manganate in water treatment

    This paper explores the feasibility of using potassium manganate (K2MnO4) in water treatment. Manganate (Mn(VI)), like ferrate (Fe(VI)), can act as both an oxidant and a coagulant/adsorbent arising from the formation of insoluble manganese dioxide (Mn(IV)) from the chemical reduction of MnO42−. In this paper the basic properties of K2MnO4 are described, including the standard electrode potential ...

  • Unique Steam Traps in Petrochem - Case Study

    Engen’s refinery in Durban, South Africa was approached by Delta Steam Systems in 2012 with a proposal to replace all steam traps in the refinery. With a nameplate capacity of 135,000 barrels per day, the refinery produces approximately 40 tons of product per hour, totaling 320,000 liters per day. When first approached by Delta Steam Systems, the refinery was experiencing massive steam ...

  • A study on fluorescence properties of carboxymethyl-quaternary ammonium oligochitosan and its performances as a tracing agent

    Carboxymethyl-quaternary ammonium oligochitosan (CM-QAOC) exhibited high inhibition to scaling and microbial formation and also remarkable fluorescence. In this paper its fluorescent properties and application as a fluorescent tracing chemical for industrial water treatment were studied in detail. The fluorescence intensities of CM-QAOC were in good linear agreement with its content in the ...

  • Evaluation of activated starch as an alternative to polyacrylamide polymers for drinking water flocculation

    Polyacrylamide polymers (PAM) are one of the most common water treatment chemicals used in clarification processes. Concerns have been raised with regards to the aquatic and human toxicity of acrylamide monomer. Greener polymers, produced using potato starch, were investigated at lab-scale as a potential non-toxic alternative to the use of PAM within a ballasted flocculation process ...

  • Kurita chemical deal solves sales dilemma

    The Japanese company has drastically ramped up its presence abroad with its first foreign acquisition in 16 years. The European sales boost will see the overseas chemicals business streak ahead of the facilities division. Kurita Water Industries has made a crucial step away from a sluggish home market in Japan with its first overseas acquisition since buying Hansu Technical Service in 1998. It ...

  • Fundamentals of Catalytic Activated Carbons

    Untitled Document Summary: Catalysts in water treatment speed chemical reactions so equipment can be scaled down or contact times shortened. Because the speed of a reaction can affect equipment price or useful life, it could mean the difference between a sale and a "no, thanks." Thus, recently developed catalytic activated carbons may enable water treatment ...

  • Understanding the impacts of allocation approaches during process‐based life cycle assessment of water treatment chemicals

    Chemicals are an important component of advanced water treatment operations not only in terms of economics, but also from an environmental standpoint. Tools such as life cycle assessment (LCA) are useful for estimating the environmental impacts of water treatment operations. At the same time, LCA analysts must manage several fundamental and as yet unresolved methodological challenges, one of ...

  • The Control of pH and Oxidation Reduction Potential (ORP) in Cooling Tower Applications

    The importance of keeping cooling tower water in proper chemical balance is becoming clearer. Cooling tower treatment control systems can limit scale formation to improve efficiency, limit corrosion to increase the service life of the cooling water system, and maintain a residual halogen level to reduce liability associated with biological growth, particularly Legionellae. The use of automatic ...

  • Reducing industrial water footprint lightens energy footprint, too

    The close connection between the water footprint of an industrial facility, which describes its overall consumption and efficiency of its water use, and its carbon footprint – much of which reflects the energy used to move, heat, cool or treat water – has never been more apparent. And as clean freshwater becomes increasingly scarce and energy becomes more expensive, reducing the water footprint ...

  • Veolia upgrades water treatment plant for Mozambique bottling plant

    Veolia Water Technologies South Africa recently commissioned a new water treatment plant for Refrigerantes Spar Mozambique Lda, a bottling plant contracted to bottle Coca-Cola and other soft drink products in Mozambique. Veolia replaced the entire water treatment plant, which treats a nominal flow of 15 m3/hour (with a peak of 20 m3/hour) of water from the municipal bulk supply, and a ...

  • Membrane fouling

    The Problem: Membrane water treatment is costly and complex due to the systems required to mitigate membrane fouling. Membranes have, therefore, been relegated to high value applications such as desalination and ultra-pure water needs. The systems used to mitigate fouling have a history of underperformance and high cost. EconoPure Solution: EconoPure has developed a low-fouling nanofiltration ...
