Automatic Pool Cleaners
The automatic pool cleaner is a device that leapt right into the hearts of pool owners and service technicians alike. In a genesis similar to that of human air flight, engineers and inventors have produced gadgets of fancy in the hopes of finding one that will fly.
Chlorine Chemistry
What is the History of Chlorine?
It was in 1774 when a Swedish chemist named Carl Scheele discovered the element Chlorine when he mixed powdered pryslusite into muriatic acid.
How does chlorine work to clean swimming pools?
Chlorine is the chemical most often used to keep swimming pools and Jacuzzis free of bacteria that can be hazardous to humans.
Pool pH Levels
The water's pH is a measure of its total acid-alkalinity balance -- the relative proportion of acids and alkalis in the water. Simply put, water that is either too acidic or too alkaline will cause undesirable chemical reactions.
Pool Chemicals
A pool's filter system does the heavy lifting in keeping the water clean, but it takes chemistry to do the fine-tuning. It's important to carefully manipulate the chemical balance in pools for several reasons:
Pool Filters
The filters in this system are high-rate sand filters. Sand filters consist of a large tank, made of fiberglass, concrete or metal, containing a thick bed of special-grade sand, which has a squarish shape.
Pool Pump Systems
To most of us, a pool is, more or less, a big hole in the ground. We don't see most of the expensive machinery in a pool system, because it's usually tucked away in nearby pump room. But this is the stuff that really makes the pool work.

Keeping the lights on
Most South Africans arrive home from work around 5pm, and follow the same evening routine of switching on lights and appliances such as fans and air-conditioners, cooking and cleaning, and entertaining themselves. This behavioural phenomenon causes demand for energy in the residential sector to more than double from 17% to peak at 35% between 5pm and 9pm.
