Pharmaceutical sludge testing

The treatment of sludge is also a major issue, as sludge contains a large amount of organic matter. If not properly treated, it can have a serious impact on the environment. So in this regard, enterprises need to strengthen management to avoid the accumulation of sludge. In addition, for some unqualified products, they should be destroyed in a timely manner to prevent environmental pollution.

Pharmaceutical sludge testingSludge and soil testing project:

Nutritional components: organic matter, ammonium nitrogen, nitrate nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, copper, manganese, zinc, boron, acidity and alkalinity, exchangeable acids, calcium magnesium ratio, magnesium potassium ratio, etc

Sludge detection for organic compounds: total petroleum hydrocarbons, benzene derivatives, volatile organic compounds, semi volatile organic compounds, polycyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons (low concentration), benzo (a) pyrene, phthalates, organochlorine pesticides, organophosphorus pesticides, polychlorinated biphenyls, dioxins, etc

Other analyses: fluoride, organic matter, moisture content, total alkalinity, phenol, mineral oil, pH value, moisture, hexachlorocyclohexane, DDT, volatile organic compounds, volatile organic compounds, polychlorinated biphenyls, semi volatile organic compounds, cation exchange capacity, etc

Sludge testing items: pH value, TS、VS，VFA、TCD、TP、TN、 Total cadmium, total mercury, total lead, total chromium, total arsenic, total nickel, total zinc, total copper, mineral oil, ammonia nitrogen, available phosphorus, sludge moisture content PH、 Mixing ratio, fecal coliform count, and mortality rate of roundworm eggs.

Pharmaceutical sludge testingOil content detection method for oily sludge

One way is to burn the crude oil components in the oily sludge under high temperature aerobic conditions of about 700C, and then use the reduction method to calculate the oil content of the oily sludge; Another method is to extract and filter the dehydrated oily sludge with an excess of low boiling point organic solvents, and then dry the "washed" sludge. The quality difference of the sample before and after constant weight extraction is the quality of the oil in the oily sludge.

Scope of sludge hazardous waste detection

Activated sludge, domestic sewage sludge, industrial wastewater sludge, water supply sludge, humic sludge, anaerobic sludge, printing and dyeing sludge, sediment, garden sludge, chemical sludge, sedimentation sludge, etc.
