  • 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.

  • Energy reduction and coagulation process control for wastewater treatment industry

    One of the biggest costs for water-water treatment is energy consumption; the cost of which is likely to escalate with increased demand. Ineffective process control may not only be costly but environmentally impacts though the inefficient use of an un-renewable resource. Furthermore, poor process control in one area may also impinge on neighbouring processes ultimately affecting effluent water quality.

  • Process monitoring and controlling for wastewater treatment industry

    Automation can save money, optimise a process and give warning of potential breeches of discharge consent. However, instrument selection is fundamentally important if a control system is to function efficiently. The measurement device must accurately and quickly respond to process variations and it must be reliable in operation if the control system is to function as intended. Designed properly, energy and chemical use can be significantly reduced, saving money and ultimately improving effluent quality.

  • Waste gas & wastewater treatment for the solar industry

    Generating solar energy is considered `green technology`, even though the production of solar cells based on silicon predominantly uses process stages that have been common practice in the semiconductor industry for many years. As in the semiconductor industry the production of solar cells employs dangerous and environmentally harmful substances, which require abatement according to legal provisions. The production of photovoltaic cells therefore is subject to strict requirements for treatment of waste gases and wastewater. Solutions need to be easy and cost-effective. The contaminated wastewaters and waste gases should, under no circumstances, lower performance, endanger the health and safety of humans, or otherwise negatively affect the availability of production facilities. The safety of the production line must be guaranteed at every step and in every operating situation.

    Water treatment for power plants

    The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

    The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

    Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

    At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.

    Chemical Water Treatment for membrane treatments

    Membrane units, in our days are widely used in the water pre-treatment preparation and are becoming one of the most important technologies in the production of high pure water. Nevertheless they often face problems with scaling and fouling and are therefore limited by frequent maintenance, downtime and high costs. Our treatment programs are specifically designed for membrane units like reverse osmosis, ultra- and nanofiltration and enable to remove or preventive control scaling and fouling. Our main target is to run these plants under environmentally friendly and beneficial economic conditions. Special attention is given to an efficient utilization of energy as well as saving precious water.

    Real-time Control System for Wastewater Treatment Plants

    Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.

    In order to meet the operational demands of modern-day plants, a new control system was developed. Proprietary control algorithms were introduced based on a large set of data from nutrient measurements in various WWTPs. The customer`s benefits are twofold: (1) achieving optimum effuent quality and, at th same time, (2) lowering energy needs and dosing of commidity chemicals.

    Water treatment solutions for the power industry

    Fossil fuel or solar-thermal power plants require clean water for their operation. Water used may contain several impurities such as calcium, magnesium or silica which can cause damages to turbines or heat exchangers. For this reason, water must be treated by ionic exchange or mechanical filtration. Also, the appropriate wastewater treatment for its reuse through sand filters in order to contribute to a sustainable water use is of vital importance.

    Ultraviolet disinfection systems for the de-ozonation industry

    Ozone is an allotropic form of oxygen; each molecule contains three atoms of oxygen instead of the usual two.  Ozone is a powerful disinfectant and has been used commercially for the treatment of potable water since 1904.  It is produced on site in the same way that ozone is formed naturally, by the discharge of electricity during a thunderstorm.  A high voltage is passed across a gas stream containing oxygen.  This method of ozone generation is called corona discharge.  The energy of the high voltage splits an oxygen molecule (02) into two oxygen atoms (0) - which recombine with ordinary molecules of oxygen (02) to form ozone (03).

    ADVANCEES - Advanced water treatment equipments for desalination

    Areas that have no or limited surface water or groundwater may choose to desalinate seawater or brackish water to obtain drinking water. Reverse osmosis is the most common method of desalination, Sea Water Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. Because no heating or phase changes are needed, energy requirements are low in comparison to other processes of desalination, though still much higher than other forms of water supply (including reverse osmosis treatment of wastewater).
