Treatment of industrial water
Industrial waste water treatment
- General
- Along the communal waste water treatment, we can offer industrial waste water treatment.
Depending on type of pollution, industrial waste water we can share on: waste water which contents organic or inorganic agents, biologically easier or harder to decompose.
Industrial waste water is increasing problem of the pollution of surface and underground waters.
Most often and most important amounts of waste water come from following industries:
- chemical industry
- metal chemical industry
- metal industry
- food industry
- textile industry
- paper industry and
- from energetic and term energetic objects.
We can offer systems for industrial waste water treatment in according with demand.
Waste water treatment in the food industry
Pročišćavanje otpadnih voda u prehrambenoj industriji
Waste water in the food industry is highly loaded with waste substances. In most waste water in food industry are present dissolved substances that are biologically easily degradable. In the case when there is a presence of hardly biodegradable biological compound, it is necessary to carry out chemical oxidation in order to degradate these compounds. Device for waste water treatment plant uses a combination of more methods: mechanical grid or sieve to remove solid impurities from waste water. Physical-chemical treatment uses the flotation device for removing substances from waste water, that would disturb the biological process with prior dosing of required chemical, coagulants and flocculants.
A sequential batch reactor (SBR) is in use for biological process, and if necessary, a membrane biological reactor (MBR).
The resulting sludge from the biological reactor and the flotation device, is collected in a sludge tank and it is draining through a spiral dehydrator. Mass of sludge is reducing several times, and can be easily further processed or disposed. The treated water has sufficient criteria to exit to the recipient of the 2. category watercourses. Guaranteed parameters are BOD5 25 mg/l and COD 100 mg/l.
