Wastewater from a textile facility contains a variety of dyes and organic chemicals from the manufacturing processes that are often difficult to treat. Spectral analysis is well suited for monitoring waste streams to identify problematic dyes prior to treatment. Continuous monitoring of effluent wastewater for BOD and COD helps to ensure effective treatment and quality of effluent to ensure regulatory goals are met prior to discharge.
Continuous monitoring of process streams and waste streams in a dairy industry setting can provide various benefits to the operators. One major benefit is that it is possible to minimize product lost to the waste stream by means of reliable online monitoring of organics (TOC) at various points in the plant. In addition, due to the nitrogen deficient nature of milk wastes it is possible to optimize ammonia dosing by accurately and continuously monitoring the organic loads entering the waste stream.
Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.
Real Tech’s analyzers can be used in municipal wastewater treatment applications to ensure environmental compliance and to increase process efficiency by continuously monitoring the incoming loads and making process adjustments accordingly to optimize aeration rates, and nutrient and chemical dosing.
Real Tech offers solutions that can provide substantial benefits to drinking water treatment plants. Continuous online monitoring can ensure water quality standards are met without the need for chemical overdosing while maintaining high confidence in the safety of the treated water. Significant cost savings can be achieved by optimizing coagulant dosage, reduced sludge production and reduced energy requirements.
Chemical plants that produce high quantities of phenols (plastics, pesticides and pharmaceutical industries) and other aromatic organic compounds are excellent candidates for wastewater characterization via spectral analysis. Chemicals that contain conjugated double bonds absorb UV radiation remarkably well. The benefits include higher precision in process control as well as optimization of wastewater treatment.
Water is fundamental to the manufacturing process in a semiconductor facility. Electronic components are rinsed or washed several times during the producing process with ultrapure water (UPW) to remove residue. Continuous monitoring of organic constituents (TOC) on the influent city water assist with UPW production. Good quality waste streams for the manufacturing process can also be monitored for reuse potential.
Treatment for drinking water production involves the removal of contaminants from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, and minerals such as iron and manganese. Ozone (O3) gas is commonly used in this contaminant removal industrial process as an effective and economical oxidizer....
A number of treatment products are often added to prevent corrosion, scaling and fouling. Coating of sensors and other effects of these products must be taken into account when selecting analyzers. Discharge monitoring needs special attention because zero measurements must be reliable over time with little maintenance.
Monitoring process streams and waste streams continuously in a brew house can provide many benefits to operations. Monitoring product in process for color or concentration provides consistency and quality measures. Product loss can be quantified by monitoring waste streams. Processes can be improved to increase efficiency and minimize effluent waste. Effluent waste streams can also be monitored for organic loading with BOD and COD correlations to ensure compliance for discharge.
Wastes that are rich in starch such as those that occur in potato processing industries require a balanced addition of other macronutrients such as nitrogen and phosphorus. In order to optimize the dosing of these nutrients it is essential to have a good idea about the organic load entering the biological treatment reactor. Measurement of colour can help with quality control and flavour consistency.
The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.
Pulp and paper waste streams are exceptionally well suited for spectral analysis due to the high concentration of UV/Vis light absorbing organics in their process water and waste streams. Continuous monitoring of the organic load by means of COD/BOD correlations will help ensure the treatment process is carried out in the most efficient way possible by optimizing aeration rates and nutrient dosing while also making sure that all the regulatory goals are met.
The most important parameters in Water/Steam Cycles such as Cation conductivity, dissolved oxygen and pH are available as pre-assembled and factory tested units. Dedicated analyzers for sodium, silica, phosphate and hydrazine are also factory tested and calibrated for immediate operation.
Being one of the key necessities of life, water should be submitted to a thorough quality control. Targeted chemical analysis of priority compounds can give an impression of the chemical quality, but may not cover the entire load of pollutants that evoke biological effects. CALUX assays are successfully applied in the identification of water samples that are polluted with biologically active toxicants even at low levels and address the complexity associated with the compound mixtures.
Aquaread stock a wide range of testing equipment designed to track a number of parameters and water quality testing measures. These can be used in many different bodies of water, including rivers, lakes, streams and seawater. The advantages of tracking water quality and testing for numerous parameters means that it is easier to notice changes which could cause damage to aquatic ecosystems. Early detection not only helps with monitoring water quality, but also helps to put mitigating measures in place. We have a...
Water is widely used in industry, whether it is encountered as raw water, process water or waste water. Very often this water must be treated before entering the process to ensure its quality and properties will meet the specifications demanded by the industrial process. In addition, with recent discharge regulations and policies towards zero liquid discharge, there is a high demand for solutions for recycling and reuse of waste water produced. Lenntech provides sustainable and complete solutions for water and...
