1. ATP Application In waste water Treatment Process

Traditional MLSS, MLVSS Will not give accurate biomass health. By using these traditional methods apart from living biomass we can know the dead microorganisms and inert materials.

Luminulta has developed the first and only commercial test kit able to accurately measure true living biomass activity and health in waste water treatment. LuminUltra’s Cellular ATP (cATP) measurement isolates the living biomass to provide unparalleled accuracy in detecting living biomass concentration. This measurement can be applied anywhere, from collection systems to aerobic or anaerobic bioreactors, return sludge streams, and effluents before and after disinfection

We can know the below parameters anywhere, from collection systems to aerobic or anaerobic bioreactors, return sludge streams, and effluents before and after disinfection.

• Cellular ATP (cATP™) – represents ATP from living microorganisms, and therefore is a direct indication of the living population. Once target thresholds for cATP are established, cATP results provide the ideal basis for operational stability, optimization, and continuous improvement of a wastewater treatment process.
• Biomass Stress Index (BSI™) – represents the stress level experienced by the microbiological population. This quantity provides an early warning of impending process problems and stressful conditions (i.e. toxicity).
• Active Biomass Ratio (ABR™) – represents the percentage of bioreactor solids that are active microorganisms. Maximizing the ABR provides many benefits such as enhanced sludge quality and improved settling.

Advantages:

• Accurately measure living biomass concentration and health.
• Optimize addition of oxygen, nutrients, and other additives.
• Detect toxicity at any point in the process or collection system.
• Early-warning of settling problems like bulking or deflocculation.
• Manage effluent disinfection processes.
• Reduction in solid waste discharge
• Proactive identification of incoming toxicity and the subsequent prevention of process upset.
• Identify optimal biomass population and adjust solids inventory to meet and maintain it
• Incrementally modify process variables (e.g. F/M, DO, etc.) to achieve significant cost savings

2. ATP Application in Cooling Towers

Cooling water systems are relatively simple processes in which water is circulated to transfer heat from one location to another. As microbiological communities grow in cooling systems, they can attach to process surfaces and form bio films. These bio films pose serious risks, reduced operating efficiency, equipment failure via microbiologically influenced corrosion (MIC), and human health risks like Legionnaire’s disease

If not properly manage Microbial growth can strongly influence corrosion, fouling, and scale formation and human health risk it leads to

• Increased maintenance cost
• More frequent shutdowns for cleaning and replacement of system components
• Reduced heat transfer efficiency and therefore reduced energy efficiency of the process being cooled
• Scale deposits and corrosion products on tube surfaces reduce heat transfer efficiency, increase energy costs, and reduce equipment life
• Increased energy consumption by refrigeration chillers
• Harmful to operators by legionella bacteria

LuminUltra’s solutions provide below quick information to the customers:

• Assess raw/make-up water quality, which can also assist in estimating loading on the disinfection process.
• Obtain a real-time indication of disinfection efficacy.
• Assess downstream locations for regrowth.
• Quantify microbial build-up on surfaces.
• Troubleshoot contamination via line breaks (trace up the line to find the source).
• Prevent premature equipment failure by prevention of microbially-induced corrosion (MIC) and line plugging.
• Supplement HACCP programs for preventative control of Legionella

3. ATP Application in Municipal Water Management

Water treatment operators typically use Heterotrophic Plate Counts to estimate the total population of microorganisms in a water sample and to supplement regulated parameters such as Total Coliform and E.Coli tests. Results are not known until several days later, HPC tests provide minimal value as a control tool since changes in the water system have already occurred well after they have been detected.

In terms of measuring total microorganisms, ATP monitoring provides, in real-time, more complete and therefore more accurate results when compared to HPC. When applied to municipal water management, ATP analyses allow the operator to assess microbial content of raw influent, disinfectant demand, and monitor the overall effectiveness of treatment.

ATP monitoring cannot replace required this testing, it is a powerful tool to guide disinfection programs and water management programs to ensure that compliance targets are met. Since upstream changes in water quality can be immediately detected using a routine ATP monitoring program, it will give operators an early indication that increased disinfection may be required.

By using ATP method customer can able to asses below places

• Assess raw & stored water quality;
• Monitor treatment efficacy (filtration, biological treatment, membranes/RO, etc.)
• Uncover contamination pathways of entry;
• Reveal regrowth hotspots (e.g. nitrification);
• Early indication of loss of Cl residual;
• Optimize flush cycles;
• Assess biofilm formation trends

4. ATP Application in Membrane/Ro Filters

The water that was supplied to residents had traditionally carried a high amount of organic material and color. In the past, organics were oxidized and broken down by chlorination prior to passing through prefilters and then a set of membrane filters. The utility therefore sought to remove pre-chlorination but complete removal of pre-oxidation resulted in severe membrane fouling and eventual failure.

Membranes are quite expensive to install and require service over time, but the more chemical treatments that are administered, the shorter the lifespan of the membrane. The fouling can also be caused by mineral scaling rather than biological fouling so it is important to treat the problem with the proper chemicals, otherwise the plant will needlessly spend money to clean the membranes using something that is not appropriate for the type of fouling that exists

ATP tests can certainly characterize the problem as being biological or not. By using ATP meter customer can know membrane fouling is due to biological problem or through chemical agent. if the issue was found to be biological, ATP tests would be used to help monitor the efficacy of both disinfection and membrane treatment throughout this optimization study.

ATP monitoring applied to membrane treatment process was able to quickly identify elevated microbial content not only in the raw and treated water, but also within the membranes themselves. This enabled personnel to assess the effects of decreased pre-chlorination, diagnose the fouling issue as a biological problem, and assess the efficacy of the membrane cleaning process – all within minutes of sample collection

5. ATP Application in Product Preservation (Coatings, latex and Paints)

Microbial growth in industrial chemicals can present a major problem. If left unchecked, microbial contamination in raw materials and intermediate products can compromise manufacturing process performance and equipment integrity. These same sources can also impact final product quality, which if not properly maintained can spoil products while sitting on the shelf. The best solution is early, accurate detection for proactive rather than reactive treatment.

LuminUltra’s solutions instantly measure the total microbiological content in raw materials, intermediates, and final products to proactively locate any potential source of microbial contamination.

• Audit the quality of raw materials to identify microbiological control risks in hours versus days or weeks with traditional methods.
• Identify contamination at the earliest possible stage of growth in intermediates and storage tanks to protect final product quality.
• Proactive control of microorganisms can contribute to a reliable reduction in final product quarantine times.
• Minimize or eliminate waste product and the costs associated with its disposal.
• Fully-quantitative detection method ensures that no contamination goes unnoticed.
• Enhanced solution ensures maximum sensitivity and resistance to interfering substances.
• Capability to detect attached (sessile) biofilm enables a more complete assessment of risk.
• Protect against microbiologically-influenced corrosion to extend asset life.

6. ATP Application in Home and personal Care products (Shampoos, Pastes, Creams, Conditioners and lotions)

Microbiological contamination is a threat to product quality in the personal care products industry.Microorganisms may be introduced at several stages of the process; subsequently, manufacturers must put in place stringent Quality Assurance / Quality Control (QA/QC) programs to manage microbiological contamination.

In most cases, manufacturers rely on traditional culture testing (e.g. dip slides, plate counts) to monitor for microbiological threats. These tests require a 2-to-5 day incubation period. Batch release must await these results, and even then there is always a risk of undetected contamination if final products are released prior to firm confirmation of microbiological contamination control.

By testing below mentioned places in chemical manufacturing plants by ATP method customer can reduce risk of contamination

• Identify contamination at the earliest possible stage of growth in intermediates and storage tanks to protect final product quality.
• Proactive control of microorganisms can contribute to a reliable reduction in final product quarantine times.
• Minimize or eliminate waste product and the costs associated with its disposal.
• Fully-quantitative detection method ensures that no contamination goes unnoticed.
• Enhanced solution ensures maximum sensitivity and resistance to interfering substances.
