Getting Started WELCOME TO WATER TREATMENT PLANT DESIGN SOFTWARE WTPSOFT02

INTRODUCTION:

Municipal water supply systems can be divided into 1. Collection Works, 2.

Transmission Works, 3. Purification Works and 4. Distribution Works. This

software deals with purification works or water treatment plants. The water

collected directly from the source may not be safe for drinking because of

physical, chemical and biological impurities. The municipal water works must

deliver to consumer the water that is (i) hygienically safe (ii) esthetically

attractive and palatable and (iii) economically satisfactory for its intended use.

Diseases like typhoid, cholera, dysentery etc. are water borne diseases. The

principal aim of the water treatment plant is to supply, clean and bacteria free

water. The water treatment plants can be broadly divided in two categories:

(i) Conventional or Filtration Plants: They remove objectionable colours,

turbidity, bacteria, and other harmful organisms.

(i i) Advanced Water Treatment Plants : These can remove dissolved inorganic

salts like chlorides, sulphates, hardness causing ions of calcium and

magnesium, excessive amounts of iron and manganese.

WTP02 software is developed for the design of conventional water treatment plant.

2.0 APPLICATIONS OF W.T.P. DESIGN SOFTWARE: -

The procedure of design of water treatment plant involved performing

repetitive calculations, which take considerable time and energy, and there are

chances of human errors. All this can be avoided by using the software for

designing the water Treatment Plant. The WTP02 Design Software can be used as

a tool in the hands of Design Engineer. It gives the dimensions of various units of

the treatment plant and their power requirement. The work of construction and

maintenance of water supply and wastewater disposal systems is generally

undertaken by Government agencies – mostly through Public Health Engineering


3

or Environmental Engineering Departments consisting of Civil Engineers. These

Departments appoint contractors for the construction of W.T.P. Many times these

contracting firms have to submit their design. Engineers from these firms can use

this software for speedy design of WTP. In the early stages of the project, the

draft project report outlining the design of water treatment plant is required to be

submitted quickly. This software can be of great use for this. Agencies such as

industries, public sector organizations appoint consultants for the design of WTP.

Engineers from these consulting organizations can use this software to increase

the productivity and profitabili ty. Academic institutions can also use this

software for teaching the students the approach for the design of WTP and also

for their consultancy cell.

DESIGN OF INDIVIDUAL UNITS: AERATOR : This is used to get rid of odour producing gases. Three types of aerators can be designed.

i) WATERFALL AERATORS: This is most commonly used.

The design criteria are as follows: -

Area of Aerator: 0.015 to 0.045 M2 / M3 / hr.

Height of Structure: 1.2m to 3 m.

Number of Steps: 4 to 6

Output gives diameter of the cascade.

(ii)SPRAY AERATORS:

Dia. of nozzles: 2.4 to 4 cm.

Time of Exposure: 2.4 seconds

(iii) DIFFURED AIR AERATORS:

Width to depth ratio of basin 1.5

Detention time of basin: 8 to 30 min. Typical: 15 min.

Air required: 0.4 to 1.2 lit of air per lit . of water.

FLASH MIXER:

Flash Mixer is designed on the basis of detention period. The output gives the dimensions of flash mixer as well as paddles. Power rating of the agitator is also given. The value of velocity gradient (G) is checked for adequacy.

FLOCCULATOR:

It is assumed that the flocculator is placed at the center of circular clarifier. This is also designed on the basis of detention period. Size of the paddles is designed so as to give satisfactory value of velocity gradient (G) and Gtd.

CLARIFIER: Clarifier is designed on the basis of overflow rate. The software gives dimensions of the clarifier and checks for the detention period and weir loading.

CHEMICAL STORAGE: The user is prompted to input the alum dose for the worst season (monsoon). The software gives the area of the room required to store the alum for the period of three months for the worst season.

FILTER:

Filter is one of the important units of the water treatment plant. This software designs the rapid sand filter, which is used in most of the plants, as well as slow sand filter. The design is based on the rate of filtration. The software gives the number of filters, area of each filter, volume of backwash water tank and the design of wash water troughs as the output.


14

The details of sand bed such as depth, effective size and uniformity coefficient along with gravel depth are given.

CHLORINE REQUIREMENT: The software gives number of Chlorine cylinders required. It is assumed that chlorinator is used. A 50 Kg cylinder is suggested for the actual requirement of 16 Kg.

UNDERGROUND CLEAR WATER RESERVOIR: Output gives the volume of clear water reservoir. The detention period varies depending on the hours of pumping. It can be as less as 30 minutes if the pumps work for 24 hours. It can be increased up to 2.5 h if pumping is done for lesser period.

PUMPS AND PUMPING MAIN: The software gives most economical diameter for pumping main, along with the total capacity of pumps required and number of pumps required. User is asked to enter length of pumping main as well as current cost of some units like pumps and cost of electricity.
