Tertiary Treatment Softener

15. PERFORMANCE CRITERIA OF THE PLANT

Raw Sewage will be brought into the Sewage Treatment Plant. The Contractor shall receive Sewage from this point to the treatment plant for treatment process.

The treatment plant shall be designed to treat the following basic characteristic expected

in the raw Sewage. However, as a specialist in the field, contractor may envisage the raw Sewage

characteristic for an factory complex. Contractor to submit his confirmation on the treatment parameter considered as an Annexure. The plant shall be capable of treating Sewage to the following standards:

Sewage from STP Average Parameter for Treatment

Suspended solid Nil

BOD5 concentration 5 ppm

COD concentration < 20 ppm

E-coli Nil Treated Sewage shall be treated for use for cooling tower make-up purpose. The

Contractor shall carefully consider the operation loading for the Sewage Treatment Plant. The final storage tank can be for 1 day retention period.

16. PROCESS DESCRIPTION

The Contractor shall design the Sewage Treatment Plant to receive continuous Sewage

inflow within the plant room allocated on the site plan. The ease of maintenance and operation is of utmost importance in the design of Sewage Treatment Plant.

The design of the Sewage Treatment Plant shall be such that it can be installed within the

allocated space and shall be subject to the approval of the Engineer -in- Charge/ Consultant. STP is proposed to use compact submerged UF membrane based Membrane Bio

Reactor (MBR) process for the treatment:

i) Sewage from main drain line is collected through gravity pipes into a screen chamber. This manually cleaned screen is provided to remove floating and big size particles, which may choke the pumps and pipe lines.



41

ii) Screened Sewage is then passed through equalization tank to homogenize the Sewage quality and also even out flow fluctuations and feed Sewage of uniform quality at constant rate to subsequent treatment units. Air mixing is also provided to mix the contents of the equalization tank. A coarse bubble aeration grid is provided to distribute air uniformly at the base of the equalization tank.

iii) After above treatment, raw Sewage is fed into aeration basin through submersible

Sewage transfer pump.

iv) In aeration tank MLSS (mixed liquor suspended solids) in the range of 12000 to 15000 mg/l are maintained. The high amount of bacteria gives better and complete removal of organic matter from the raw Sewage in relatively small area. Oxygen required for the bacteria is supplied through the blower. The air is used both for scouring of membranes and supplying oxygen to bacteria.

v) The MBR process is a technology that consists of a suspended growth biological

reactor integrated with an ultra-filtration membrane system, using membrane. The ultra-filtration membranes are immersed in an aeration tank, in direct contact with mixed liquor. The membrane module consists of housing, aeration diffuser, permeate water manifold and membrane elements. Through the use of a permeate pump, a vacuum is applied to a header connected to the membranes. The vacuum draws the treated water through the ultra-filtration membranes. Feed water including activated sludge is filtrated by membranes with pore size of 0.1 – 0.04 micron meter. The air bubbles supplied from the bottom of the membrane elements continuously scour off cake of activated sludge accumulated on the membrane surface. This is a continuous filtration operation. The air bubbles are also used for the biological reaction to decompose organic substances included in the raw Sewage.

vi) The material of the membrane shall have high stability for chemicals and good

physical strength. The form of membrane shall be fibre reinforced flat sheet membrane. The membrane shall have small and uniform pore size so that the rejection property of this membrane is excellent. Almost all particles with sizes more than 0.1 – 0.04 micron metre can be removed effectively using this membrane.

vii) The filtration shall be carried out by the suction pump directly sucking permeates

water. The permeate water produced is clear and devoid of bacteria and viruses to the minimum levels.

viii) As the membranes are continuously under operation, they are polluted with organic or

inorganic substances. Hence, chemical cleaning shall be carried out once in two to three months for removing substances polluting and clogging the membranes. Normal cleaners used are sodium hypo chloride and citric acid.

ix) The treated Sewage from the Sewage Treatment Plant shall be stored in Treated

water storage. The treated water is to be used for the Cooling tower make up, horticulture and flushing purpose.

x) Excessive sludge shall be stored in the sludge holding tank for final dewatering and

disposal through screw pump and filter press.

The hand jacking pump shall be applied to increase the system pressure to 2

times the working pressure or 1.5 times the working pressure plus 3.5 bar whichever is the lower but in any case not less than 7 bar. The pressure shall be maintained for a period not less than 24 hours.

Where any section of pipework or equipment is found to be unable to withstand

the maximum pipework test pressure, it shall be isolated during the pipework test then that section of pipework or equipment shall be made good and re-tested at the appropriate test pressure.

The working pressure for various systems shall be as shown on the drawings.
