  • How do DTRO systems differ from other membrane systems?
    DTRO (Disk Tube Reverse Osmosis) systems are specifically designed to treat heavily contaminated industrial wastewater and can handle higher pressures and more demanding wastewater types.
  • What are the benefits of DTRO?
    The DTRO (Disk Tube Reverse Osmosis) offers several advantages over a regular spiral wound RO (Reverse Osmosis). Here are some of the key advantages of DTRO compared to traditional spiral wound RO systems: Fewer clogging problems : DTRO passes water through narrow, cylindrical channels lined with membranes, minimizing the risk of clogging compared to the flat wound modules in traditional RO systems. Clogging can affect pressure buildup and performance. Robustness and durability : DTRO modules are more durable and resistant to operating conditions with high solids concentrations or difficult effluents due to their robust construction and structured arrangement of the membranes. They can more effectively handle difficult effluents that could normally cause blockages. Higher concentration efficiency : DTRO systems are better suited to handle higher concentrations of dissolved solids. The special structure of the membranes and the unique flow design allow DTRO modules to handle high concentrations of solids without compromising performance. Less cleaning required : Due to the less prone structure to clogging and deposits, DTRO modules generally require less frequent cleaning compared to traditional RO systems. This results in improved uptime and lower maintenance costs. Better performance in difficult wastewaters : DTRO systems are ideal for treating difficult wastewaters with high concentrations of solids, COD or other difficult-to-degrade contaminants. They offer reliable performance even under challenging conditions. Scalability: DTRO systems can be scaled well to meet the needs of different applications. They are flexible and can be used in various industries, from wastewater treatment to seawater desalination. Overall, DTRO offers improved performance and reliability when treating challenging wastewater and process streams compared to traditional wound-wound RO systems. The use of DTRO can result in more efficient and cost-effective water treatment, especially in areas with high solids concentrations or difficult wastewater.
  • Can PFAS be separated using reverse osmosis?
    The removal of PFAS (per- and polyfluorinated alkyl substances) using reverse osmosis (RO) is possible, but there are some important considerations to take into account: Size and structure of PFAS molecules : PFAS are organic compounds with strong carbon-fluorine bonds and variable molecular size. Some PFAS molecules can be relatively small and may be able to pass through the membranes of reverse osmosis systems. Membrane permeability: Standard RO membranes can have different permeabilities depending on the size and chemical nature of the PFAS molecules. Some PFAS compounds can penetrate the membranes, while other larger or highly charged molecules are retained. The pH of the wastewater must also be taken into account here. Removal effectiveness: Studies have shown that reverse osmosis systems tend to effectively remove PFAS compounds, especially those with longer carbon chains or larger molecules. However, small or less charged PFAS molecules may have a lower removal rate. Retention rates can be optimized by adjusting the pH. Membrane type and treatment conditions : Special RO membranes optimized for PFAS removal may have higher efficiency. In addition, operating conditions such as pressure, temperature, and flow rate can affect the performance of reverse osmosis in PFAS removal. Reverse osmosis is an effective method for removing PFAS from water, especially when special membranes are used and operating conditions are optimized. Nevertheless, it is important to note that efficiency may vary depending on the specific properties of the PFAS compounds. Therefore, it is advisable to evaluate the performance of reverse osmosis on PFAS in laboratory studies or pilot tests to determine the optimal treatment strategy.
  • Do ZLD applications make sense in every case?
    The question of whether Zero Liquid Discharge (ZLD) applications always make sense depends on various factors, including the type of industrial processes, the available resources and local environmental regulations. It is important to consider both the energetic aspects and the limit values to be observed in the wastewater. Energy aspects : ZLD systems typically require significant amounts of energy, especially for evaporation and drying technologies. Energy consumption can be high, leading to increased operating costs and additional environmental impacts due to the use of energy sources. Before implementing a ZLD system, it is important to conduct a comprehensive energy assessment to ensure that the benefit of waste prevention justifies the additional energy costs. Wastewater volume and composition : ZLD is particularly useful in industries where large volumes of wastewater are generated and/or the wastewater contains high concentrations of pollutants or salts that cannot be easily disposed of. In such cases, ZLD can help to recover valuable resources such as water and minimize waste. However, the use of ZLD is not always necessary or economical, especially when the wastewater volume is low or the pollutant concentrations are moderate. MLD (Minimum Liquid Discharge) applications are often sufficient if the wastewater can be treated energy-efficiently via reverse osmosis and fed back into the process, while the resulting concentrate still complies with discharge regulations. Environmental regulations and limits : Many regions have strict environmental regulations and limits for wastewater, especially for certain pollutants, salts or chemicals. ZLD may be required to comply with these limits and avoid the discharge of contaminated wastewater into the environment. The use of ZLD should be seriously considered in such cases to minimize environmental impacts and meet legal requirements. Economic considerations : Implementing a ZLD system can require a significant investment, including the cost of equipment, energy consumption and maintenance. It is important to conduct a cost-benefit analysis to determine whether the long-term benefits of ZLD justify the initial investment and operating costs. In summary, ZLD is not always the ideal solution for every industrial application. MLD can be an alternative. It is important to consider the specific circumstances and requirements of the company, including energetic aspects, wastewater volume and composition, as well as applicable environmental regulations and economic considerations. In some cases, alternative wastewater treatment approaches such as pretreatment, reuse or off-site disposal (for small wastewater volumes) can be an effective and more cost-effective option.
  • What are the advantages of the Bloom Absolut Filter?
    The Boom Absolut Filter has a defined filter fineness due to its special structure. The filter medium consists of small glass balls whose geometry precisely defines the gaps (filter fineness). The filter is operated automatically so that operation can take place without interruption for filter candle changes. This saves money on labor costs and replacement filters, as well as waste disposal fees for used filter candles. All in all, a sustainable concept.
  • Do I still need reverse osmosis after ultrafiltration?
    The working range of ultrafiltration is different from that of reverse osmosis. If you want to discharge treated wastewater, ultrafiltration is usually sufficient to comply with the required limit values. The finest particles or even emulsified oils or fats are safely retained. If you want to recycle the wastewater, the water quality achieved by ultrafiltration is usually not sufficient, as it allows dissolved salts in the wastewater to pass through the membrane. This is where the working range of reverse osmosis begins, which can also safely retain dissolved salts and small organic molecules. If you want to recycle your wastewater, you cannot avoid reverse osmosis. Special trace substances such as PFAS (per- and polyfluorinated alkyl compounds) or pharmaceuticals can only be safely separated using reverse osmosis.
  • Don't evaporators use too much energy to treat wastewater?
    Modern evaporators usually work using the vapor compression method. Up to 95% of the energy required for evaporation is recovered internally. In practice, the steam generated is compressed using a Roots blower and heated up further. The energy from this hot steam is then transferred to the wastewater to be evaporated via a heat exchanger, thus closing the energy cycle. This makes it possible to evaporate one m³ of pure water with an energy quantity of 35 kWh. This value is higher for contaminated wastewater. Here you can expect 60 - 70 kWh/m³. Evaporation as a method of wastewater treatment is particularly useful for wastewater that has certain properties, such as highly concentrated wastewater (industrial wastewater from chemical production or saline wastewater), or for organic substances that are difficult to degrade and for wastewater that is contaminated by chemicals, heavy metals or other toxic substances and cannot be safely treated in any other way.
  • Can used highly alkaline cleaners be recycled?
    Highly alkaline cleaners, such as those used in bottle cleaning or textile cleaning, can be freed of their impurities using our alkali-resistant NanoPro membranes. The nanofiltration membrane allows the cleaning component, the caustic soda, to pass through the membrane while impurities such as aluminates or organic residues are safely separated. The membranes can be used up to a concentration of 20% NaOH. This saves chemical costs for the preparation of the new cleaner or costs for neutralization during wastewater treatment.
  • Why are plasticizers suddenly on everyone's lips? Are they also in the wastewater?
    Plasticizers are chemical substances that are often used in plastics to improve their flexibility and stretchability. In principle, all PVC plastics that have to be flexible contain plasticizers, such as cables, hoses or textiles. Even medical devices and packaging contain plasticizers. What is so worrying about this? Some plasticizers, particularly certain phthalates, are suspected of causing health problems. They can cause hormonal disorders and impair male reproductive ability. Plasticizers have been detected in drinking water and in the urine of small children. Due to their harmful properties, phthalates have been generally banned in baby products and toys in the EU since 2005. In order to protect drinking water, many countries have applied stricter limits for DEHP (di(2-ethylhexyl)phthalate). This can be a problem for laundries, for example, as synthetic fibers often release phthalates. One way to safely and efficiently separate plasticizers is to use membrane processes such as nanofiltration and reverse osmosis. We are happy to help you.
