PROPOSED SEWAGE TREATMENT SYSTEM

Based on the literature available and after study of wastewater characteristics the

following treatment system has been designed for treatment of waste water. The

proposed treatment system consists of three stages:

Stage I: Primary Treatment

It consists of three units Bar screen chamber, Grit Chamber, Neutralization tank

cum Equalization tank.

Stage II : Secondary Treatment

It consists of five units Aeration tank, Secondary clarifier, Clarified Water

storage tank, Sludge holding tank & Filter Press.

Stage III: Tertiary Treatment

In this treatment the treated water will be further treated and polished using

sand filter, Activated carbon filter. After the treatment the water will stored for

gardening and other purposes etc.

WASTE WATER GENERATED (1440 KLD) STP Capacity 1500 KLD

Treatment Scheme:

Primary treatment

Bar screen chamber:

Screen is the very first operation carried out at treatment plant, and consists of passing

the wastewater through screens, so as to trap and remove the floating matter, such as

pieces of paper, wood, cork, hair, fiber, etc., present in wastewater. These floating

materials if not removed, will choke the pipes, or adversely affect the working of the

pumps. Thus the main idea of providing screens is to protect the pumps and other

equipments from the possible damage due to the floating matter.

Bar screens are provided with an inclination of 300-600 to the direction of flow. Large

floating matter is obstructed by these screens. The screens are to be cleared frequently

by manually to allow free flow of wastewater in to the treatment system.

Grit Chamber:

The waste water came from the bar screen chamber flows into the grit chamber where

the solids will be collected and clear wastewater flows to the final collection tank for

further usage.

Equalization/Neutralization Tank:

The wastewater varies widely in its characteristics both qualitatively and

quantitatively and hence to equalize the waste water air flow line is provided. At this

stage the pH value should be maintained in between 7.5-8.0.

11

Secondary Treatment

The coagulation of non – settleable collection solids and the stabilization of organic

matter contributing to BOD are reduced by principally by bacteria. The

microorganisms convert the colloidal and dissolved carbonaceous organic matter into

various gases and into cell tissue. Because cell tissue has a specific gravity slightly

than water the resulting tissue can be remove from the liquid by gravity setting.

The converter of organic matter into gaseous end products and cell tissue can be

accomplished aerobically. An aerobically or facultative suspend growth or attached

growth system. In aerobic conversion apart of the organic matter is converted to end

products and other part to obtain the energy for the synthesis of new cells and hence

the growth.

In most biological treatment systems, these three processes occur simultaneously in

the activated sludge process, the bacteria are the most important microorganisms,

because they are responsible for the decomposition of organic materials in the

influent. In the reactor, or mixed reactor, or mixed liquor tank, a portion of the organic

waste matter is used to obtain energy for the synthesis of the remainder o f he organic

material into new cells.

While bacteria are the microorganisms, that actually degrade the organic waste in the

influent, the metabolic activity of other microorganisms is also important in the

activated sludge system.

12

For example protozoa and rotifers act as wastewater polishers protozoa consume

dispersed matter that have not flocculated and rotifers consume small biological

flocculated particles that have not settled.

Aeration Tank

Supernatant from the Primary clarifier over flows in to the aeration tank where the

organic matter in the wastewater is biologically decomposed under aerobic

conditions. The mixed liquor in the tank is aerated by using 1 no. slow speed diffused

aerator. The MLSS in the aeration tank is maintained around 4000 mg/l by return

sludge, dissolved oxygen of 1 to 3 mg/l has to be maintained. The detention time in

this tank is around 6 hours. The mixed liquor from this tank over flows into the

secondary clarifier.

Secondary Clarifier

The mixed liquor from the aeration tank overflows into the lamella clarifier. Here the

wastewater is kept under comparatively quiescent condition. This allows the solids

from mixed liquor to settle. The mixed liquor enters the drum of the clarifier at the

center and distributes itself equally of all sides. It leaves through the periphery of the

tank. The wastewater moves very slowly facilitating setting of sludge at the bottom as

specific gravity of sludge is higher than that of water. The required amount of sludge

is recycled and the rest is bleed out.

13

Sludge Filter Press

Hydraulically operated filter press will be installed with 12 nos. of plates to dewater

and cake will be used as manure.

Sand Filter and Carbon Filter

The wastewater from secondary clarifier over flow into sand filter where any traces of

organic matter will be removed. Further, the effluent overflow in to activated carbon

filter, there the wastewater will be treated by the principal adsorption and removes

partially total dissolved solids. The clear supernatant will be sent to polishing pond

for recirculation into process or to use for Green belt development.

6.0 RAIN WATER HARVESTING

The storm water disposal system for the premises shall be self-sufficient to

avoid any collection/stagnation and flooding of water. The amount of storm water

run-off depends upon many factors such as intensity and duration of precipitation,

characteristics of the tributary area and the time required for such flow to reach the

drains. The drains shall be located near the carriage way along either side of the roads.

Taking the advantage of road chamber, the rainfall run off from roads shall flow

towards the drains. Storm water from various plots/shall be connected to adjacent

drain by a pipe through catch basins. Therefore, it has been calculated to provide 172

rainwater harvesting pits at selected locations, which will catch the maximum run-off

from the area.

1. Since the existing topography is congenial to surface disposal, a network of

storm water pipe drains is planned adjacent to roads. All building roof

water will be brought down through rainwater pipes.

2. Storm water system consists of pipe drain, catch basins and seepage pits at

regular intervals for rainwater harvesting and ground water recharging.

Rain water harvesting has been catered to and designed as per the guideline of

CGWA. Peak hourly rainfall has been considered as 0.03m/hr. The recharge pit of

adequate diameter and depth is constructed for recharging the water. Inside the

recharge pit, a recharge bore is constructed having adequate diameter and depth. The

ground water level in the area is 20-30m bgl. At the bottom of the recharge well, a

filter media is provided to avoid choking of the recharge bore. Design specification of

the rain water harvesting plan are as follows:

Catchments/roofs would be accessible for regular cleaning

The roof will have smooth, hard and dense surface which is less likely to be

damaged allowing release of material into the water. Roof painting has been

avoided since most paints contain toxic substances and may peel off.

All gutter ends will be fitted with a wire mesh screen and a first flush device

would be installed. Most of the debris carried by the water from the rooftop

17

like leaves, plastic bags and paper pieces will get arrested by the mesh at the

terrace outlet and to prevent contamination by ensuring that the runoff from

the first 10-20minutes of rainfall is flushed off.

No sewage or sullage would be admitted into the system

No sullage from areas likely to have oil, grease or other pollutants has been

connected to the system.

7.0 VEHICLE PARKING FACILITIES

For plotted development the parking shall be provided within the plots by

the individual plot owners. It is proposed to construct one multi-store

parking facility in commercial area.

8.0 SOLID WASTE GENERATION

Solid waste would be generated both during the construction as well as

during the operation phase. The solid waste expected to be generated

during the construction phase will comprise of excavated materials, used

bags, concrete, MS rods, tiles, wood etc. The following steps are proposed to

be followed for the management solid waste:

Construction yards are proposed for storage of construction materials.

The excavated material such as top soil and stones will be stacked for

reuse during later stages of construction.

Excavated top soil will be stored in temporary constructed soil bank and

will be reused for landscaping of the plotted colony.

During the operation phase, waste will comprise domestic as well as

landscape waste. The solid waste generated from the project shall be mainly

domestic waste and estimated quantity of the waste shall be approx. 3462

kg per day @ 0.50 Kg per capita per day for residents, @ 0.15 kg/day for

visitors and landscape waste @ 0.2Kg/acre/day.

Following arrangements will be made at the site in accordance to Municipal
