WASTE WATER TREATMENT

FOOD INDUSTRY

Compact systems, easy to install Cleans Water for discharge to sewer Small Footprint Completely automated Simplified operation Low maintenance Flows up to 3000L/h CE certified

www.ventilaqua-equipments.com Compact solution developed for wastewater treatment in several food applications. Inlet wastewater is treated by a coagulation/DAF system as a pre treatment or for direct discharge into sewer network. This solution has a small footprint, low capital investment and easy installation.

WORK SCOPE

PROJECT DATA

Wastewater characteristics: Wastewater results from washing operations, fish cleaning and fish filleting. This wastewater contains a substantial amount of contaminants in soluble, colloidal and particulate form. This results in load values above limits approved by regulation authorities for water discharge, such as FOG`s, Suspended Solids, COD and BOD.

Providing a system to treat fish processing wastewater for saving money on reducing sewage fees. The system reaches up to the following removal rates: 60% COD; 90 % Suspended Solids and 90% FOG`s.

Inlet COD - 5000 mg O2/L Inlet BOD - 2000 mg O2/L SS - 1500 mgO2/L FOG`s - 1000 mg/L

The waste water treatment in this case has the following steps: Furthermore, the system is controlled with an electric board. This screening, buffer tank, chemical coagulation / flocculation system allows a very efficient depuration, reducing COD, BOD, treatment process by flotation (VAMEF) and sludge dewatering FOG`s and SS, in accordance to regulations and usual requiresystem (PSS). ments.
