Subject /
Treatment of sewage / industrial mixed with oils and grease in the septic tanks collecting from washing areas for equipment, machinery and vehicles in the ports of Alexandria and exotic plants by diverting them to the public sewer to the sewage network of Alexandria

Introduction /
Problem was dealt with almost a month ago to send the analysis results provided by the Wastewater Treatment Plant assembly of exotic ports of Alexandria and showing high rates of dissolved oxygen and percentage of bio-chemical oxygen, dissolved, and the level of oil mixed with water, which is jammed networks uploaded for the station, the main difficulty of the quality of treated water from these orchards, the ports

In this sector the occupational safety and industrial security department led by Eng / Ahmed Rizk your Director of Occupational Safety and his team, represented by competent By this, a partial Engineer / Yasser Saad dealing with us and faxing, telephone and email, as well as bring in samples from septic tanks on for all tests and experiments required to resolve this exemplifies the problem

When fully successful in the laboratory separation of oils and grease from the water completely and bring water quality into line with the required public sewer demands formally requested the sector of occupational safety set a date for testing on the ground to determine the quantities of chemicals required for further treatment and to identify the equipment required in the septic tanks for processing sound easy and safe

Have been identified in the appointment on Wednesday, 24/3/2010 were interviewed Mr. Eng / Ahmed Rizk and his team tags have been moving to areas of septic tanks, were as follows: -

Dekheila Port /
Number 4 groves (civil tanks)
first is to collect waste exchange resulting from the washing)
(civil tanks 2 / 3 is the groves separate oil and grease from water)
(civil tanks IV, waste exchange wastewater resulting from the chapter)

Port of Alexandria /
Number 3 groves
(civil tank)
the first compilation of the exchange resulting from the washing)
civil tank second to separate the oils and grease from water)
(civil tank a third orchard exchange wastewater resulting from the chapter)

The samples were taken from the waters civil tank No. 4 from the port of exotic and civil tank No. 3 from the port of Alexandria
In order to conduct realistic tests of the proposed chemicals on the quality of water in the success of the chapter has been completely out pure water by 90% and deposition of waste oil and grease in semi-solid in such a way to get rid of the suction

The request for the establishment of management capacities reservoir engineering as well as the rate of filling reservoirs daily wastewater prior to discharge into public sewer

Has been to meet with Mr. / Tarek Sabri, deputy director of the company's ports of exotic and Alexandria to brief him on the matter and to determine the programs and style of treatment were asked us to send all the scientific information and chemical materials used and the safety data, environmental and occupational have to completely safe handling of chemicals and water without any environmental problems for waste/sweage water treatment puplic stations Lifting and handling network and the mother and the environment and Environmental Affairs

Technical Proposal /

First / style separation of oils and greases
Separation device operates at the port of exotic oils efficiently 70% and oil separation device operates at the port of Alexandria, 60% efficient
Causing exit quantities ranging between 30-40% of oil and grease mixed with sewage before discharge to the pumping stations and connected to the main treatment plant

II / bites of septic tanks
Capacities ranging civil tanks final (fourth orchard drainage) in the exotic port of between 12-17 cubic meters, while capacities ranging civil tanks final (Pardes exchange civil tank III) in the port of Alexandria between 16-22 cubic meters

III / exchange rate to the public sewer station
Where each orchard equipped with 3 buoys on the dimensions of 3.5 cubic meters / 8.5 cubic meters / 13.5 cubic meters in the port of extraneous
As the port of Alexandria Pardes equipped with 3 buoys on the dimensions of 4.5 cubic meters / 10.5 cubic meters / 16.5 cubic meters
And all the orchard with a valve lock and open the water before discharge to waste water uploaded

And was therefore to calculate the rate of fully fill the reservoirs with less quantity is 3.5 cubic meters for the Port exotic and the amount of 4.5 cubic meters for the port of Alexandria, and that these quantities the rate achieved per day varies from summer period for the winter, when the rates are populated entirely more than once in the winter much more for summer rainfall and regular cleaning of their effects, and dirt

IV / equipment necessary for the treatment /
Provision of 2 mixer speed 4500 rpm to achieve a fully water-mixing with oily chemicals to achieve the deposition processes and co-agulation and flottation and entirely separate

V / provide the required chemicals
