microbial detection for slurries and mineral suspensions





aqua-tools I&E provides rapid analysis solutions for evaluating the biological quality of slurries and preventing performance loss due to microbial contamination.

Slurries are solutions of fine, insoluble mineral particles suspended in a solvent (most often water). Precipitated calcium carbonate slurries (milk of carbonate of lime) are used often in paper manufacturing (as a coating), the agro-food industry (as an additive), pharmacology (as a diluent), chemistry (as a component), etc. These slurries are generated by direct carbonatation of hydrated lime in an aqueous environment (milk of lime) followed by dehydration (to generate powdered solutions) or concentration (to generate spreadable pastes). As calcium carbonate is not harmful to humans, it can be ingested with no ill effects as long as it is completely free of micro-organisms. Other sensitive application may also require a supply of pure water, deionized water, water purified by reverse osmosis, etc.

Due to their composition and the exothermic reactions that occur during processing, slurries and the “white water” generated by the associated procedures favor the growth of micro-organisms. A high biological burden (of bacteria, fungi, protozoa, algae, etc.) can affect quality and even pose a health risk. To avoid the generation of harmful substances and to ensure that only good quality effluents are recycled, the quality of the water used in different procedures or finished products must be rigorously managed. Industries use preventive chemical treatments (biocidal agents) and have begun to use biological analyses to track microbial contamination. However, these analyses do not always account for the wide diversity of microbes that can proliferate in these specialized nutritional environments. Learn more
