DESTINY FATE IN ISLAM IN NUTSHELL

DESTINY FATE IN ISLAM IN NUTSHELL

Tawakkul means putting in one’s best efforts—leaving no stone unturned, and then putting one’s trust in Allah and not in one’s own efforts or availability of the means one has, because whatever the outcome, it comes about only with the approval and decree of Allah and not otherwise. It is reported that one day Prophet Muhammad (SAW) noticed a Bedouin leaving his camel without tying it and he asked the Bedouin, “Why don’t you tie down your camel?” The Bedouin answered, “I put my trust in Allah.” The Prophet then said, “Tie your camel first, then put your trust in Allah.” 

To work and to strive is within the ability and the limits of man..whether the striving is accepted or not, or whether the desired result is achieved or not is entirely in the Blessed Hands of the Lord Most Majestic Who Created Alone!.

OPERATION MANUAL FOR 10 KLD ETP CHEMICAL DOSE OF ALUM

OPERATION MANUAL FOR 10 KLD ETP

OPERATION INSTRUCTION :

1.         The total quantity of waste water from kitchen for which the ETP is designed is 10,000 liter per day. The unit functions 8 hours in a day .There is no flow at day.The ETP is designed for continuous flow treatment of effluent at a average flow rate of 1250 liter per hour. The air blower will have to be run continuously for mixing of chemicals in reaction tank and flocculation tanks.

2.         Allow all the effluent of the day generated to enter the underground collection tank. Collected effluent is planned to be pumped continuously for eight hours at a average flow rate of 1250 liter per hour . The plant and machinery cant take more than this flow.

.

CHEMICAL DOSING  :

1.   Lime, add 20 Kg per day to maintain pH at 10 at collection tank. Check pH at Collection tank after adding lime manually. pH maintaining is extremely important or alum will not work properly. Use it up in one day.

2.    Alum, add 15 Kg in the auto doser tank of the reaction tank in 100 liter of water and use it up in one day. pH will come down to 8 after addition of alum.

3.   PAC, add 100 gm in the auto doser tank in the flocculation tank and use it up in one day.

COMMON INSTRUCTION FOR ETP  :

1.   When the pumps are on, the blower must be on also for mixing the chemicals with water. Note down the time in log sheet.

2.   The Auto doser for alum in reaction tank should be on when pump is on. Note down the time in log sheet

3.   The Auto doser for PAC in flocculator should be always on continuously when pump is on. Note down the time in log sheet

4.   Fill the auto doser tank with fresh water and mix the estimated chemical in it for the day and set it at the desired dose. Note down the time and quantity in log sheet

5.   Preventive maintenance of pumps and blowers like oiling etc should be regularly done.

6.   Note down the pH of the inlet and outlet water and note it at log sheet.

7.   The waste sludge from tube settler is to be suitably disposed off to the sludge drying bed by opening the valve provided at the hopper bottom of the tube settler.

8.   Backwash the Sand filter and carbon filters after each 4 hours.

9.   Raw and treated effluent is to be analyzed periodically for pH, TSS, BOD and O&G. .

10.Skilled Operator will be required  to carry out all these instructions.

11.The operator will maintain a log book. And chemical stock registers.

12. The performance of the ETP is dependent on the proper skill of the operator and proper chemical dosing.

Polishing pond for Magur fish in ETP treated water.

Polishing pond for Magur fish in ETP treated water.

 Oxygen level in the tanks should exceed 3 mg/l. If the magur fish tanks are supplied with turbid water it is advisable to filter it with through a sand filter and to aerate the tanks at night for maintaining oxygen level by using an air blower The aeration grid should be one feet above the bottom of the tank so that mud can settle at the bottom..Magur requires mud. .

A tank containing such a fish group required approximately 5 liter/min water supply. Depth of fish tanks should be 0.5–0.75 m. Let us take water depth 0.75 meter.The freeboard of the tank should be 0.5 meter so that fish don’t jump out. So total depth of tank is 1.25 Meter. Volume of the tank should be 10,000 liter. Normally it should be square in size. So length and width of tank will be 4 Meter by 4 meter. 

For avoiding the direct contact between tank wall and fish it is better to cover the inner surface of tank with polyethylene sheet.

Inlet water should be sprayed in the tank from a perforated PVC tube throughout the length.

Outlet water will overflow from a overflow weir at the outlet side. The top of the overflow weir will be covered by net/mesh. The proper mesh size is 1.0–1.5 mm

Most efficient way of plankton maintenance is frequent manuring with small doses of poultry or cattle manure. In addition to plankton maintenance, frequent manuring maintains an active and effective bacterial population in pond water. It facilitates decomposition of metabolites hampering fish growth. Poultry (5–15 kg/bigha) or cattle (10–20 kg/bigha) manure is sufficient for frequent treatment of pond.

Daily brushing of wall and bottom of the tanks is essential. Moreover, when there is deterioration in water quality, 10–20 % fresh water replacement is suggested.

Lime is used for killing different living organisms remaining in muddy pools after dewatering of ponds.

IF MAGUR SURVIVES IN THE POLISHING TANK, IT MEANS THE ETP IS RUNNING PROPERLY.

TANK SIZE : 4 x 4 x 1.25 Meter. Water depth = 0.75 Meter. Free Board=0.5 M
