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.
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.
Problem: Waterborne pathogens can cause serious disease outbreaks. Drinking water disinfection forms the final barrier between these pathogens and humans. For drinking water disinfection, ultraviolet (UV) light has proven to be the best method for inactivation of Cryptosporidium parvum and Giardia lamblia parasites found in natural waters. Organic matter and suspended particles in water absorb and scatter UV light, interfering with pathogen inactivation by UV irradiation.
Problem: Prior to environmental discharge, wastewater is disinfected to ensure pathogens present in the water are inactivated. Ultraviolet (UV) disinfection is becoming a widely accepted treatment technology for wastewater disinfection due to the deleterious effects of chlorine on aquatic life. The ability for the UV light to penetrate the water is directly related to the concentration of suspended particles and organic matter in water that absorb or scatter the light.
SorbEater is a synthetic super-absorbent with the highest oil recovery ratio of ANY known absorbent material resulting in less product required and less product to dispose of.
This provides significant savings on the costly disposal fees associated with hazardous waste.
It is highly effective on fresh water, soil, sand and sea. During development it outperformed the traditional organic peat products in every test.
Ideal for: Any hydrocarbon spills or contamination. It has been used successfully with...
Bentonite can be mixed with pesticides and fungicides as a support carrier to fix the product to the leaves. In organic farming, the action of fungi and parasites is inhibited by bentonite – a natural product – thus replacing chemical products. In particular, this process is employed in biodynamic cultivation of wine grapes, where bentonite is mixed with other elements to fight oidium. In liquid and solid fertilizers, it is used as a fixing carrier and to control the release of nitrogen, potassium,...
Hydrogen Peroxide as a Replacement for Sodium Hypochlorite
Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution.
H2S + NaOH → NaSH + H2O
4H2O2 + H2S → H2SO4 + 4H2O
Typical dose ratios are 5 parts H2O2 per part H2S or, when...
