Tekst o wprowadzaniu i walidacji nowych metod badań mikrobiologicznych wody.

Three sets of 10 drinking water samples were inoculated with primary treated effluent from three locations. Volumes of 250 ml of each sample were inoculated with sufficient effluent material to generate counts in the range of 20-80 cfu/MPN per 100 ml. 100 ml volumes of each sample were analysed by the trial method (Enterolert-DW) and the reference method (ISO 7899-2). All samples were processed and incubated according to the manufacturer's instructions or the relevant standard method. For the trial method, replicate counts of positive wells were made by two analysts after 24 hours of incubation. Numbers of positive wells were converted to MPN prior to being tabulated.

pierwotnie oczyszczone ścieki
Explanation:
oczyszczanie pierwotne” oznacza oczyszczanie ścieków komunalnych za pomocą procesu fizycznego i/lub chemicznego, obejmującego osadzanie zawiesiny lub inny proces powodujący, że BZT5 dopływających ścieków jest przed odprowadzeniem zmniejszany o co najmniej 20%, a zawiesina jest zmniejszana o co najmniej 50%;

Primary and secondary treatment of sewage, using the activated sludge process. ... Suspended solids that pass through screens and grit chambers are removed from the sewage in sedimentation tanks. These tanks, also called primary clarifiers, provide about two hours of detention time for gravity settling to take place.

Primary treatment
Primary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation. Screens are made of long, closely spaced, narrow metal bars. They block floating debris such as wood, rags, and other bulky objects that could clog pipes or pumps. In modern plants the screens are cleaned mechanically, and the material is promptly disposed of by burial on the plant grounds. A comminutor may be used to grind and shred debris that passes through the screens. The shredded material is removed later by sedimentation or flotation processes.

Secondary treatment
Secondary treatment removes the soluble organic matter that escapes primary treatment. It also removes more of the suspended solids. Removal is usually accomplished by biological processes in which microbes consume the organic impurities as food, converting them into carbon dioxide, water, and energy for their own growth and reproduction. The sewage treatment plant provides a suitable environment, albeit of steel and concrete, for this natural biological process. Removal of soluble organic matter at the treatment plant helps to protect the dissolved oxygen balance of a receiving stream, river, or lake.
