Aquatic respiration can be simply yet accurately measured on intact, live organisms using a variety of Strathkelvin Instruments respirometry systems.
As with all of our respirometry systems, an aquatic system would comprise of an oxygen meter (either 782 or 928), one or more, high precision, 1302 oxygen electrodes (link) and a respiration chamber to house the organism.
The researcher also has a choice of measuring respiration rates via closed or flow-through respirometry. Both closed and flow-through systems...
Physico-chemical parameters alone are not sufficient in obtaining reliable information on treated wastewater. Online toxicity monitoring must be performed in combination with routine chemical analysis. The assessment of biological effects of wastewater discharges in the ecosystems is today considered relevant and ecotoxicological tests identifying the ecological hazard are useful tools for the identification of environmental impacts.
The food and beverage industry is suffering from severe economic pressure. Efficient and continuous production processes are therefore business critical. By choosing Kurita concepts for your cooling water, boiler water and waste water plants as well as your reverse osmosis systems and autoclaves – all of which are specially adapted to your needs – you opt for economic and ecological treatment, leading to more productivity and cost-efficiency.
The analysis of volatile organic compounds at low concentration levels is fundamental to pollution monitoring and control.
Hiden’s Hydramass spectrometer is a multi-stream gas analysis system for analysis of volatile organic compounds to the sub ppm level.
In sea water the analysis of volatile organic compounds is used for both pollution monitoring and ecological studies.
Hiden’s HPR 40 dissolved species analyser provides ppb sensitivity
Both economic and ecological demands make maximum dewatering of sludge a most crucial step in the process flow, especially for the pulp and paper industry with their large quantities of sludge to handle. A highest possible dry content of dewatered sludge minimizes weight and volume, hence achieving the following objectives: reduction of transport and disposal cost. high heating value for incineration without additional fuel. With the sludge dewatering systems including both AKSE S disc thickener and AKUPRESS BX...
Sulfide Odor Control
Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing...
