Heavy Metals Wastewater Treatment System (Chrome Removal): Chromium is present in the wastewaters of a number of industries, including: stainless steel manufacturing, protective coatings on metal, magnetic tapes, chrome plating, tanneries, textile dyes production, pigments and paint production, production of cement, paper, rubber, etc. Chromium is typically precipitated in two steps: reduction and precipitation.
Acid mine drainage (AMD) is typically characterized by low pH and high dissolved iron. The acid mine drainage may also contain high amounts of CO2 which forms carbonic acid and further depresses the pH.
For characterization and remediation of contaminated soils, sediments, and sludges, EDXRF (XRF) analysis provides quick and reliable assays. Energy Dispersive X-ray Fluorescence is a standard technique recognized by the U.S. EPA and is routinely employed to determine heavy metal concentrations (RCRA metals) in soils and sediments. In addition to soils, Rigaku XRF spectrometers may use used with the UltraCarry technique to quantify trace metals in aqueous (water) samples down to part-per-billion levels. Rigaku's...
Continuous measurement of sludge coming from a digestion tower and being pumped through a heat exchanger. Required to detect possible blockage or reduced pump performance and to ensure permanent heat supply for the WWTP social areas.
Chemical processes make very high demands on electronic pressure measuring instruments and hydrostatic fill level probes in two respects: processes may be complex with high dynamic pressures and fast changing temperatures the media are diverse and may be chemically aggressive, explosive, toxic, abrasive and sometimes also dirty and viscous. Add to this top safety requirements, especially in explosion hazardous plant and equipment and the absolute demand for top operational reliability.
Scientists these days believe that the natural resources of oil and gas are not quite as finite as thus far assumed. These resources are likely to remain available considerably longer than hitherto predicted.
Using Oxygen to Solve Waste Water Problems
Lack of oxygen can cause inadequate purification or even anaerobic decomposition, as well as offensive odors. Injecting oxygen into sludge beds &/or piping allows you to:
* Reduce nitrogen levels
* Meet peak O2 demands
* Have a back up to your aeration system
* Pre-purify waste water
* Control odors
* Deter corrosion damage
* Meet increased requirements regarding waste water purification
Improved monitoring and automation can deliver more efficient waste treatment and reduced energy consumption and improved effluent quality. The cost of treatment and the quality of effluent discharge can thus be significantly reduced.
Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...
Rapid turnaround is essential when an oil or fuel storage tank is stripped for repair or scheduled maintenance. This time-sensitive process can be frustrated by the presence of high vapor levels and unpumpable sludge. Over the past 30 years, BioSolve Pinkwater has proven to be a worker friendly solution to these challenges.
Respiration rate of activated sludge has been recognised as a key controlling element in the modelling of process control, by the International Water Association Task Group. Actual respiration rate of the sludge in the aeration tanks, as well as the endogenous and maximum respiration rates are variables that indicate the rate of BOD removal and aeration requirements. The maximum respiration rate is also closely linked to the Critical Oxygen Concentration point, that is, the point at which diffusion over the...
From the remote Canadian wilderness to the mountainous regions of South America, Schwing Bioset piston pumps are called upon for reliable service in some of the harshest environments on the planet to pump tailings to surface and sub-surface disposal. Schwing Bioset Fluidized Bed dryers and conditioners are trusted when reliability and performance are a must to process coal at your power generation facilities. Schwing Bioset piston pumps can be used to pump wood waste, coal slurries and fly ash at ethanol and...
If toxicity is identified in a mixed sewage entering a treatment works, the problem for the plant manager is to track and identify the source of the toxicity. This can be done by sampling the effluent stream at various points in its length. By working in a logical sequence back up the sewer network the number of samples can be minimised. This type of testing should be rigorously enforced for new product introduction by a waste producer, as well as sampling the effluents directly at source. The samples would be...
To meet the requirements of new regulations and to protect the environment effectively, industries need techniques that enable the analysis of elements at lowest concentration levels. Bruker X-ray fluorescence (XRF) analysis is the most suitable analytical technique for handling different kinds of materials. Bruker’s XRF, ICP-MS, GC, TOF-MS, FT-IR, CBRNE products and applications help you to monitor contaminated land efficiently and quickly, to determine hazardous elements in the air and water, as well as...
