    Ultraviolet disinfection systems for the total organic carbon (TOC) reduction sector

    Total Organic Carbon (TOC) is found in all water supplies as naturally occurring organic matter. Over many years of experience, medium or low pressure UV treatment has become recognised as an effective process step in the breakdown and reduction of TOC in water intended for use in pharmaceutical, health care, power generation and micro-electronics applications. In the latter case, ultra-pure water is used to wash silicon wafers on which even small deposits of carbon compounds on the wafers can severely affect their performance.

  • Wastewater solutions for wastewater UV disinfection performance

    Problem: Prior to environmental discharge, wastewater is disinfected to ensure pathogens present in the water are inactivated. Ultraviolet (UV) disinfection is becoming a widely accepted treatment technology for wastewater disinfection due to the deleterious effects of chlorine on aquatic life. The ability for the UV light to penetrate the water is directly related to the concentration of suspended particles and organic matter in water that absorb or scatter the light.

  • Optimization of Wastewater Processing and Operations

    The biocatalytic composition Bio-Organic Catalyst (BOC) provides numerous benefits for all of the biological processes (aerobic and anaerobic) used to convert waste loadings into high quality discharges. The array of benefits made possible with BOC can be applied system-wide to bring critical solutions to the fundamental challenges of operators. Odors, improving dissolved oxygen levels, reduction of organic loadings and biosolids, bio-film build up, elimination of Fats, Oils & Grease (FOG), and improvements in discharge quality are all operating parameters that can be improved with use of BOC.

  • Wastewater Colour Removal

    The presence of colour in water and wastewater, even a small amount, is highly visible and affects the aesthetic value. Colour is often caused by organic matter. Forms of organic content that cause colour pollution include synthetic chemical dyes, algae species and natural dissolved organics such as lignin and tannins.

  • Wastewater treatment for the meat and derived industry

    The water from this type of industry generates large amount of solids. The main sources of this waste are the phases of evisceration and blood draining, which contribute a large organic load. The application of our products is ideal for the treatment of this type of water.

  • Residential Areas and Hostelries wastewater treatment

    Residential Areas and Hostelries wastewater, including water generated by domestic use, by shops, restaurants and laundries, must be adequately treated to meet the discharge requirements of public sewers or channel, or reuse as irrigation water mainly.

    This wastewater has the following characteristics:

    • Variations in flow depending on the time of day and season (mainly in tourist areas).
    • High suspended solids content.
    • Presence of oils, fats and detergents.
    • High concentration of easily biodegradable organic matter.
    • Adequate concentration of nutrients.

  • BOD and COD Removal

    Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD / COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. These include: Predigestion of wastewaters which contain moderate to high levels of compounds that are toxic, inhibitory, or recalcitrant to biological treatment (e.g., pesticides, plasticizers, resins, coolants, and dyestuffs); Pretreatment of high strength / low flow wastewaters – where biotreatment may not be practical – prior to discharge to a Publicly Owned Treatment Works (POTW);Enhanced separation of entrained organics by flotation and settling processes; and Supply of supplemental Dissolved Oxygen (DO) when biological treatment systems experience temporary overloads or equipment failure. http://www.h2o2.com/industrial/applications.aspx?pid=104&name=BOD-COD-Removal

  • Drinking Water Treatment

    The AnoxKaldnes™ MBBR technology is an ideal solution for treatment of potable water whenever there is a need for removal of biologically transformable pollutants, such as NH4+, NO3- or organic compounds. In most cases, pollution levels in drinking water are relatively low, putting demands on a biological process to be able to maintain a high concentration of active microorganisms despite low incoming substrate concentrations. The fixed-film of AnoxKaldnes™ MBBR fulfills this very well and is successfully applied for removal of pollutants in concentrations of a few mg/L.

  • Wastewater Treatment for the Bioenergy Industry

    The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

    The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

    Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.

    Reduce biofilm formation

    In many industrial or professional applications where water is being stored, biofilm may grow. The growth of biofilm can damage the installations and reduce efficiency of the circuit. A biofilm can grow certain substrates which can be found in water. When temperatures are high, for example in cooling towers, a matrix of different micro- organisms such as bacteria, fungi, algae can grow very rapidly causing the formation of a biofilm on certain surfaces submerge in water. During the formation of this biofilm, certain micro organisms starts producing extra cellular polymeric substances (EPS) which reinforce the biofilm structure.

    Water oxidation for private an public drinking water

    Carus permanganates have been used in private and public drinking water applications for more than 40 years. Municipal drinking water plants use CAIROX® and AQUOX® potassium permanganates, and CARUSOL® liquid permanganate in both ground water (well) and surface water for Pretreatment, Pre-oxidation and Organics Removal. Today, municipal water providers face increased challenges as more stringent regulations are enacted and public awareness regarding water quality becomes heightened.

    Advanced water treatment equipments for deionization

    Deionized water, also known as demineralized water (DI water or de-ionized water; can also be spelled deionised water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.
