Meat-processing industryWastewater generated from meat-processing and poultry enterprises is highly concentrative and those consisting grease and suspended solids which require preliminary treatment at local WWTPs before entering biological WWTPs.The main wastewater contaminants indicators at meat-processing and poultry enterprises are the following:
In order to achieve the demands placed for wastewater discharged to the municipal collecting channel (biological WWTPs) treatment from such contaminants as suspended solids and greases is required. Besides, treatment from mineral contaminants and pH value control is also required. Depend on wastewater treatment requirements Ecopolymer Group specialists have developed wastewater treatment technologies which correspond to municipal collecting channel (picture 1) or poultry ponds (picture 2) discharge standards. For large meat-processing enterprises, which have their own slaughter workshops it’s advisable to construct WWTPs, which consist of local WWTPs with mechanical and physicochemical wastewater treatment devices. The effectiveness of wastewater treatment applying screen and flotator with chemical stage unit can be reflected through the following indexes:

Typical flow chart of wastewater treatment up to the rates of fishery ponds discharge standards  Flotation devices Sludge and excess activated sludge treatment are carried out at mechanical dehydration workshop. Dehydration equipment is being selected considering the physicochemical features of sludge and activated sludge mixture.
