Abstract
Hard water has taste and wastes soap. An electronic water softener was constructed using the NE 555 electronic timer in a stable multivibrator mode. It was designed to operate at a frequency of 15 kHz and powered by a 12volt battery which delivered 150mA to the oscillator circuit. An activity indicator was designed to monitor the working state of the water softener. The water softener was tested on hard water samples obtained around Kaduna city. The results obtained indicated a total removal of hardness in mildly hard samples, and a great reduction of hardness level in very hard water samples used. The electronic water softener is an efficient and very cheap way of softening hard water that can be used in homes and industries
