Industrial wastewater – fish processing

Categories:

ATT & AT d.o.o. can offer quality engineering solutions for industrial wastewater treatment. Process wastewater treatment plants are designed according to the requirements of production, investors, and the required output parameters of purified water. In wastewater of seafood, special attention should be paid to the high concentration of chlorides, because chlorides act very aggressively and it is necessary to choose high-quality equipment resistant to the aggressive effects of chloride in wastewater. Wastewater treatment from the fish industry consists of a combination of mechanical pre-treatment and physico-chemical treatment. The device consists of: pump shaft, fine mechanical treatment, aerated equalization tank, flotation device DAF (dissolved air flotation), a dosing station for chemicals, pipe flocculator, sludge tank, the station for automatic preparation and dosing of polyelectrolyte, and purified water tank. The treatment process can be adjusted at any time by means of control units installed in the facility in which the process wastewater treatment plant is located.

Meat industry – slaughterhouse and meat production
ATT & AT d.o.o. can offer quality engineering solutions for industrial wastewater treatment. Process wastewater treatment plants are designed according to the requirements of production, investors, and required output parameters of purified water. Wastewater treatment from the dairy industry consists of a combination of mechanical pre-treatment and physico-chemical treatment. Considering that in the technological wastewater from the meat industry there is also a larger waste of animal origin, mechanical treatment is performed in two stages, coarse mechanical treatment, and fine mechanical treatment. The purification process consists of: coarse mechanical treatment, pump shaft, fine mechanical treatment, aerated equalization tank, flotation device type: DAF (dissolved air flotation), a dosing station for chemicals, pipe flocculator, aerated sludge tank, tank for sludge preparation, sludge filter press, MBBR biological reactor and polyelectrolyte preparation and dosing stations. The purification process is fully automated and requires minimal monitoring of the purification process by the operator on the device.

Input parameters:
• amount of wastewater per day: 100 m3/day
• COD: 5000, peak load up to 8000 mg/l
• BOD: 2000, peak load up to 3500 mg/l
• suspended solids: 2650 mg/l
• oils and fats: 350 mg/l

Required output parameters:
• COD: 700 mg/l
• BOD: 250 mg/l
• oils and fats: 100 mg/l
• sediments: 20 ml/lh
• pH: 6.5-9.5

Wastewater treatment plant consists of:
• coarse mechanical treatment
• pump shaft
• fine mechanical treatment
• aerated equalization tank
• flotation device DAF (dissolved air flotation)
• dosing station for chemicals
• pipe flocculator
• aerated sludge tank
• sludge preparation tank
• sludge dewatering filter press
• MBBR moving bed biofilm reactor
• automatic polyelectrolyte preparation and dosing station
