| gen. | adaptuotas dumblas | adapted sludge |
| environ. | aktyvintas dumblas | activated sludge Sludge that has been aerated and subjected to bacterial action; used to speed breakdown of organism matter in raw sewage during secondary waste treatment |
| life.sc., environ. | aktyviojo dumblo kvėpavimo slopinimo tyrimas | activated sludge respiration inhibition test |
| life.sc., environ. | aktyvusis dumblas | biological sludge |
| life.sc., environ. | aktyvusis dumblas | activated sludge |
| environ. | atliekų dumblo likučiai | residual waste sludge The excess, unusable semi-solids or sediment resulting from a wastewater treatment or industrial process |
| environ. | atliekų ir dumblo kompostas | refuse-sludge compost compost made from mixture of sewage sludge and compostable refuse or waste; Compost derived by the biodegradation of the organic constituents of solid wastes and wastewater sludges. The major public health issues associated with composting using solid wastes mixed with sewage sludge are pathogens, heavy metal, and odors. The heat generated during composting, as a result of the activities of thermophilic organisms, is capable of killing bacteria, viruses, protozoa and helminths present in sewage sludge. The metallic elements in sludge of greatest concern to human health are cadmium, lead, arsenic, selenium, and mercury. Only cadmium is normally found in sewage sludge at levels which, when applied to soils, can be absorbed by plants, and accumulate in edible parts, thereby entering the food chain |
| environ. | biologiškai apdirbtas dumblas | digested sludge Sludge or thickened mixture of sewage solids with water that has been decomposed by anaerobic bacteria |
| environ. | dehidruotas dumblas | dehydrated sludge Sludge whose water content has been reduced by physical means |
| environ. | dumblo apdorojimas | sludge digestion A treatment to stabilize raw sludge. The treatment can be either anaerobic process or aerobic process |
| environ. | dumblo deginimas | sludge incineration A method used for drying and reducing sludge volume and weight. Since incineration requires auxiliary fuel to obtain and maintain high temperature and to evaporate the water contained in the incoming sludge, concentration techniques should be applied before incineration. Sludge incineration is a two-step process involving drying and combustion after a preceding dewatering process, such as filters, drying beds, or centrifuges |
| life.sc. | dumblo kvėpavimo intensyvumas | sludge respiration rate |
| environ. | dumblo nusodinimo tvenkinys | sludge settling pond Pond for the removal of settleable solids through which wastewater is passed in a treatment works |
| environ. | dumblo stabilizavimas | sludge stabilisation Usually anaerobic sludge digestion, a treatment that stabilizes raw sludge. Fully digested sludge has little readily biodegradable organic matter. It is not smelly and about 50% of the solids are inorganic. Sludge can also be digested aerobically |
| environ. | dumblo valymas | sludge treatment The processing of wastewater sludges to render them innocuous. This may be done by aerobic or anaerobic digestion followed by drying in sand beds, filtering, and incineration, filtering, and drying, or wet air oxidation |
| life.sc. | dumblo šalinimo laipsnis | sludge wastage rate |
| econ. | kanalizacijos dumblas | sewage sludge |
| life.sc. | modifikuotas tariamai nepertraukiamas aktyviojo dumblo metodas | modified semi-continuous activated sludge test |
| life.sc. | modifikuotas tariamai nepertraukiamas aktyviojo dumblo metodas | modified SCAS test |
| environ. | nuotekų dumblas | sewage sludge A semi-liquid waste with a solid concentration in excess of 2500 parts per million, obtained from the purification of municipal sewage |
| environ. | nutekamojo vandens dumblas | waste water sludge The removed materials resulting from physical, biological and chemical treatment of waste water |
| life.sc. | perteklinio dumblo šalinimo laipsnis | surplus sludge wastage rate |
| environ. | pramoninis dumblas | industrial sludge Sludge produced as a result of industrial production processes or manufacturing |
| life.sc. | tariamai nepertraukiamas aktyviojo dumblo metodas | semi-continuous activated sludge test |
| life.sc. | tariamai nepertraukiamas aktyviojo dumblo metodas | SCAS test |
| life.sc. | tariamai nepertraukiamas aktyviojo dumblo įrenginys | semi-continuous activated sludge unit |
| life.sc. | tariamai nepertraukiamas aktyviojo dumblo įrenginys | SCAS unit |
| environ. | valomasis dumblas | clearing sludge |
