Wastewater

Highlights of the Next Five Year Plan 

for the Wastewater Research Program at KISR, Kuwait

Dr. Abdallah Abusam

Introduction

* Kuwait is situated in a harsh environment characterized by very little rain fall (100 mm/yr) and very limited freshwater (groundwater) resources. alt

* Reclamation and reuse of wastewater will help augmenting the overall water availability in Kuwait.

* Huge amounts of wastewater are available all through the year.

* Treated wastewater can be reused in domestic, industrial and agricultural sectors, resulting in reduced demand for high quality water.

* Economic and environmental benefits.

* About 800,000 m3/d municipal wastewater is treated at 4 main central activated sludge plants located at Jahra, Riqqa, Sulaibiya and Um-Al-Haiman areas.

alt

* About 65% of treated wastewater is reused as agricultural and landscape irrigation water.

alt

* Advantages of Activated Sludge systems:

- Fast and Efficient removals, e.g. BOD.

- Minimum land requirements.

- Few environmental nuisance.

- Controllable effluent quality.

* Disadvantages of Activated Sludge systems:

- Susceptible to shock loading.

- Needs skilled operators.

- Expensive capital and maintenance costs.

* Sustainability Criteria for Water Treatment Technologies (van Lier et al., 1998):

- No dilution of high strength wastes with clean water.

- Maximum recovery and reuse of treated waste water and by-products.

- Application of efficient, robust and reliable technologies which are low-cost, have long life-time and plain in operation and maintenance.

- Applicable to small as well as big scales.

- Leading to self-sufficiency.

- Acceptable for local population.
