How to Improve Wastewater Effluent Quality?

Published on by in Technology

How can we improve the wastewater effluent quality from any manufacturing industry?

I'm looking for new ideas to reduce operating costs and mitigate the effluent effect on the environment.

Can you suggest any alternative methods for treatment?

Furthermore, does anyone have suggestions on technology improvements to the available technology for waste water treatment?

    Hello it's very simple

    It is already necessary to define the word used because there is used water and used water

    Domestic chemical waste water

    Organic domestic wastewater

    Biochemical industrial waste water

    Industrial chemical waste water

    Heavy industrial biological waste water

    Once the definition of used water in question determines its pollution load

    Determine the characteristics of pollution


    To improve a waste water it is necessary to tackle the source of the pollution that is injected into the water and to reduce it if it is possible or to modify certain pollution by taking less toxic pollutants alternative to see biological if possible

    Then adapt a treatment that purifies each type of pollutants

    After if the effluent is totally biological lyseconcept proposes its purification biotechnology

    In fact it is simple

  4. Hello Maya,

               It is possible to monitor the BOD, microbial activity and toxicity of industrial effluents in near-real time using pressure based measurements (respirometry). One key advantage is the lack of maintenance required because sensors  are protected from this aggressive environment. The Shepherd system (Bactest) can help you monitor the loading, the reaction of the  biomass to that loading in activated sludge, and the oxygen required to process it. Should a toxic event occur, the system senses the change in biological activity and alerts accordingly, allowing rapid remediation. The system has both local display and cloyd based dashbouard so that all historical data and trends can be accessed remotely.

    I hope this is helpful.  Derek Price

  6. Hello Maya,

    Hydrodynamic Cavitation could well be a suitable technological application for you to appraise. Please view my contacts page and follow the instructions to find papers which hydrodynamic cavitation successfully treats waste water effluent streams.

    Should you be interested in what you find then lets get together for a meeting, we have a laboratory scale test rig, which is a scaled down version of our industrial sized units, that can be hire for testing to see how our equipment performs for your given effluent stream(s) and what you are trying to achieve.

  7. Dear Maya,

    There are common steps to treatment of industrial waste water treatments.Primary, secondary & tertiaryDepending on the type of industry and the nature of its wastes, industries must utilize methods such as those used for advanced treatment of sewage to purify wastewater containing pollutants such as heavy metals and toxic chemicals before it can be discharged. Industries are permitted to discharge directly to receiving waters under the National Pollution Discharge Elimination System (NPDES) permit system or to municipal sewers under the Industrial Pretreatment Program. Pollution prevention programs are very effective in helping industries reduce discharged pollutants, by eliminating them at the source through recycling or through the substitution of safer materials. More and more industries are approaching or attaining zero discharge by cleaning and reusing their water over and over and over.

  8. Hi Maya,

    For industrial treatment plants, we have observed common issues within the aeration basin being a loss of efficiency with some submerged type equipment overtime, leading to a loss in meeting effluent norms.  The aeration equipment we manufacture carries a consistent oxygen transfer rate throughout the life of the unit (Aire-O2 Triton Process Aerator / Mixer).  These units are surface mounted which allows for simple maintenance one unit at a time, keeping other units in operation and effluent consistent while minimizing cost. Another way to help minimize cost is the ability to operate the equipment in the dual-mode.  The Aire-O2 Triton carries a low-speed mixer motor and a blower.  Once oxygen levels are reached at low-flow periods of the day, the blower can be turned off in which the mixer stays on; keeping solids in suspension.  The system can be automated around the required DO levels for consistent effluent and energy savings.  See the YouTube video here for a bit more clarity.  https://www.youtube.com/watch?v=5jGti60mdE8

    Feel free to message me with any further questions!

    All my best,

    This wide range quastion please specify so we can suggest,  is it upgrading .

    Thank

  10. Hello All; Maya; Here in Baltimore, Maryland; USA; we employ tertiary water treatment at the manufacturers effluent point source; commonly called pre-treatment. In the USA, it is federal mandated law that any and all industries must pre-treat their waste stream before the effluent enters the municipal waste stream. We do not separate sewage from industrial waste streams. So; the solution to your situation is to apply the necessary cost to pre-treat your effluent with tertiary level wastewater treatment technology. The primary cost will pay for itself over the lifetime of your industrial operations. You may achieve approximately a 95% level of effluent purity at the point of exit. We have employed this technology over the last 30 years with repeated successful results and minimal to none violations of water quality laws.

  11. I have not once wrote about the fact that our company has developed an INNOVATIVE technology , which ( wastewater treatment ) USES MICROORGANISMS . The sewage treatment process passes in the closed mode for a few seconds. When cleaning, apply only physical methods and processes. Water after purification can be reused or submitted for irrigation or dumped in the river. ( lake) . We invite interested parties to verify this with existing objects .

  12.  Я уже несколько раз писал, о том, что МЫ РАЗРАБОТАЛИ НОВУЮ, ИННОВАЦИОННУЮ ТЕХНОЛОГИЮ ОЧИСТКИ СТОЧНЫХ ВОД , которая не применяет в своей работе микроорганизмы. Процесс очистки проходит в ЗАКРЫТОМ РЕЖИМЕ ЗА НЕСКОЛЬКО СЕКУНД за счет физических процессов, проходящих в данном аппарате.  Если это  интересно и нужно -  приглашаю посмотреть  на действующих объектах. Себестоимость очистки  можно посчитать  по затратам эл энергии - у нас это 0,7 кВт на 1м3 очищаемых стоков. = 0,5 дол США. 

  14. Maya Jones I would like to discuss this with you.  Currently we are implementing technology to treat and reuse industrial and municipal wastewater.  We are currently getting potable water from raw sewage and using reusing it for all water needs in the building thereby eliminating discharge and reducing dependence on water utilities.  Looking forward to speaking with you.

  15. Chère Maya

    En lisant votre demande et en regardant les propositions qui sont jointes on reste dans le même schéma de votre problématique.

    Pourtant la solution est toute simple: le traitement à la source. Mais pas un traitement de gestion comme c'est le cas de nos jours, mais un traitement d'épuration à la source.

    Bien entendu on ne peut pas mélanger les eaux usées domestiques et les eaux usées industrielles. Le travail peut la aussi se faire à la source.

    Les eaux usées domestiques épurées à la source par un processus -biologique- ne produisent pas de résidus. Le coût de traitement d'épuration est donc milles fois plus performant. 

    C'est une solution globale et définitive

    Dear Maya

    By reading your application and looking at the proposals that are joined one remains in the same pattern of your problem.

    Yet the solution is quite simple: the treatment at the source. But not a treatment of management as is the case today, but a treatment of purification at the source.

    Of course you cannot mix household sewage and industrial wastewater. Work can also be make to the source.

    Domestic wastewater purified by a biological - process source - producing no residue. The cost of treatment of treatment is a thousand times more powerful. 

    It is a comprehensive and definitive solution

     

  16. Dear Maya,

    Unfortunately there exists no silver bullet (universal best) solution to improve the quality of ANY industrial wastewater. The most efficient and sustainable solution for each industry will need to be a tailored one.

    Hence I agree with Engr. Mansoor to look at the broader picture which  starts by water-wastewater saving and management in the production processes and steps including multiple water use, substition, direct  recycling after simple physical treatment (e.g. by sieves, filters). This will reduce at least the volume of wastewater to be treated and save considerably cost in builiding and operating a wastewater treatment plant. In this way we helped industries to reduce their fresh water consumption and corresponding wastewater production by up to 70%.

    Regarding wastewater treatment one should at least make a distinction between mainly organic and mainly inorganic (mineral) wastewaters. The organic ones can be purified most cost-effectively (after adequate pretreatment equalization and conditioning) by advanced biotechnology which also captures and biodegrades "slow" food (recalcitrant organics including colour) in addition to the readily biodegradable "fast" food.

    1. Hello  Maya, We are currently reducing all odors, in less than three days and Nitrogen in less than a month.  With our special blends from  over 300 Microbes, we can also reduce Sludge and TSS in less than three months.  Naturally we can only treat Organics with this system however we can also eliminate, Cyanno and e-coli Bacteria.  We can render chemicals such as PCBs  down to non carcinogenic. 

       

  17. Dear Maya,

    Regarding Industrial Wastewater Effluent Quality which reflects that you do not have any WWTP at the moment (lets assume) then you need to do the following; 

    Cleaner Production Planning:

    1) You need to opt for the chemicals in processing which are environmental friendly or less harmful to environment

    2) Minimize/controlled utilization of Fresh Water in Process which in result generate less wastewater

    3) Use 80 / 20 Principal, check the main processes where the water consumption is highest, and try to focus on those processes only so improvement is significant. People does mistakes they go for wash room taps or other small things.

    4) Segregation (if possible as this is the most difficult task in any running industry to segregate most polluted streams from fairly clean/or low polluted streams). 

    5) Segregation will enable you to decide if some of the most polluted streams if could be onsite treatment or reuse (like in textile industry mercerize is separated and recovered by Caustic Recovery Plants), low polluted or fairly clean wastewater can be reused (like in textile industry reuse of last rinsing baths etc.). These all will enable you to have less wastewater at the end of the pipe.

    Once you are done with Cleaner Production Planning/Options; then there must be inevitable wastewater coming out of the factory.

     

    Now if you are looking for a good Treatment Options:

    Treatment Technologies depends upon many criteria like incoming pollution loads, space available, energy requirement, end use of the treated wastewater etc. The designer could offer you a good treatment scheme depending upon your requirement and your constraints and with technological limitations as well.

    1) if you have plenty space available like Sugar Industries have far bigger space available, then facultative ponds, vertically constructed wet lands are the options to go for, low energy, cheaper solution , good output.

    2) if space is a constraint, then you need to go for Physico-Chemical and Biological Treatment (in some cases, Anaerobic Treatment as well).

     

    Improving the Effluent Quality from your existing Treatment Plant:

    For this one needs to know your treatment scheme existing, what effluent quality you are having and what is your target, what inlet quality you are having and how could you improve it.

    However, there could be some open solution;

    If you have gravity settling, then adding Lamella Sheets or Tube Settlers could improve further the settling

    adding post filtration (sand filter and/carbon filter after secondary clarifier) may give better results

    There could be more improvement techniques but needs further data to suggest you the right solution.

    Hope this could be a comprehensive answer to your question.

  18. Hello Maya,

    Industrial effluent management is now  very crucial process. However, we have been working on the principle of water and wastewater budgeting for sometime now. Instead of going for alternative treatment technologies, you can adopt segregated wastewater treatment techniques, which can have a significant reduction of financial allocation and increase the treatment efficiencies without having any environmental liabilities.

  19. Dear Maya,

    This is a very vague query. Give more details on what kind of effluent?,  which type of industry?, how much is the effluent quantity?

    Improving quality of effluent depends on all the above & many more parameters. 

  20. Dear Maya, is the waste biodegradable (at some extent)?
