WATER CRISIS

WATER RATIONING BY OPERATORS

Looking For Answers…

The word ‘fi’ (within) in the Qur’anic phrase /fil’ard / (within the ground), points to the possibility that indicates underground sources of water, not sources that are above the ground.

“And We sent down water from the sky in

measure, and We lodged it in the earth, and verily We are able

to take it away” (Qs. Al-Mu’minûn [23]: 18),

4. River Barrage for Artificial Recharge

5. Consultation cost & Land acquisition

STORAGE = BUFFERING

3R concept – Recharge, Retention and Reuse

• Local (cisterns) and subsurface storage (active use of aquifer) of surface water for both water- and food security

• Its not about allocation of scarce water but to catch and retain water and extend the chain of use and reuse as possible within a basin

• Introduce buffer management at scale – basin by basin. Not piecemeal/scattered

• Subsurface storage largest potential in terms of Volume

River Barrage FunctionsRiver Barrage Functions

1. Control of Reservoir Level and Flood Control2. To impound fresh water in reservoir and exclude seawater from entering the reservoir.3. To release storm water flows to sea before the raising of the fresh water impoundment in reservoir for flood control and prevention.

- ‘War’ on Use of Water

Energy Efficient & Costs Savings

1. Energy Costs reduced– + High Eff.Pumps & VSD

2. Maintenance is minimised – Excavators, Pumps

3. Filter operation is optimized – less backwash

4. Very Little Sludge – no sludge management

5. Optimization of WTP Whole Operation

Energy savings up to 45% with the RBF effect and VSD usage.

Objective of ‘Ozone-Oxidation’

• Oxidation of metals as iron and manganese• Tastes and odours removal• Oxidation of organic matters and micro pollutants• Algae Removal• Improvement of the coagulation• Colour removal• Reduction of THM

36

BENEFITS OF OZONE :-

TASTE AND ODOUR CONTROL

• Taste and odour is often caused by Chlorination of natural organic compounds: phenol, hydrogen sulfide, algae,...

• Chlorine + Phenol = taste + toxic compound

• Oxidation of organics by ozone:

• non toxic compounds

• no taste and odour

COLOUR REMOVAL

• Colour in surface water is caused by natural organic matters (humic-, fulvic-, tannic acids,…)

• These matters reveal C=C bonds

• Ozone reacts with carbon double bonds

• A dosage of 2 to 4 mg(O3)/L leads to a strong colour removal in most of the cases

BENEFITS OF OZONE :-

BENEFITS OF OZONE :-

IRON AND MANGANESE REMOVAL

• Ozone oxidises ferrous and manganese to insoluble compounds

• Chlorine does not oxidise manganese

• Fe/Mn removal commonly takes place in pre-ozonation

• Metal hydroxides may be removed on sand filters

What is Ozone …

Molecular weight: 48 g/mol

Density @ 1013 mbar, 0°C: 2,14 kg/m³

Max. limit for ambient level: 0,1 ppm
