Food industry project for chip processing in Egypt

4.500m³ Industrial wastewater treatment plant for Food Industry

SITUATION

Chipsy is the leading international company in the potato chips & snacks industry. During the past few years; chipsy has managed to carry-out several upgrades to reduce water requirements and at the same time increase the production rate. And that resulted in increasing the organic load concentration in the waste water, leading to necessity to attain optimization and upgrade of the aeration waste water treatment system, in order to enhance the treatment process and be able to handle the high organic load concentrations, while preserving the increase in the production rate and water savings.

It was required to increase the Standard oxygen Transfer Rate (SOTR) of the Sequencing Batch Reactor (SBR) aeration tanks from 80-100 (kg O2/hr) to 160-200 (kg O2/hr).

PROBLEM

In the Old wastewater aeration system, Jet Aerators were used to deliver oxygen in the Sequencing Batch Reactor (SBR) tanks. There are two scenarios to fulfil the required upgrade, by doubling the number of het aerators in each of the two SBR jet aerated tanks, and utillizing the new advanced aeration system engineered and commissioned by PuriChem Integrated systems and PPU-Umwelttechnik GmbH for the other two SBR Tanks.

SOLUTION

PuriChem Integrated systems along with their German Partners PPU- Umwelttechnik GmbH designed new advanced industrial wastewater aeration system to replace the old jet aerated system. The new industrial wastewater system has been applied to Two of the Four SBR aeration Tanks.The industrial wastewater treatment plant sytem is designed to deliver fine bubbles at a wide range of air rates. By insuring an even bubble distribution. The positive displacement blower is extremely robust with a compact design, and being installed above the ground had a great impact on lowering maintenance requirements and making the access, operation and monitoring of the apparatus very easy.

The maintenance cost of industrial wastewater jet aeration system is nearly 150,000 EGP/year for the single jet aerator, so if the first scenario was applied the maintenance cost of all SBR tanks jet aerators will be 1,200,000 (EGP/year) while the maintenance of the new advanced aeration system is 100,000 EGP /year.The new advanced wastewater treatment plant is very easy to access & maintain unlike the jet aerators which are totally submersible in water.
