Reverse Osmosis (RO) for Water Purification

Reverse osmosis, often abbreviated to RO is a purification procedure that uses membrane technologies to filter and purify liquids. Reverse osmosis is now commonly used around the world for the treatment and purification of water used for drinking (potable water) and industrial processes.

Reverse osmosis makes use of a semipermeable membrane to separate unwanted materials found in the raw water (solute). These materials can include salts and minerals, bacteria and other contaminants.

Rainwater Harvesting, Water Reuse & Greywater Recycling

Rainwater harvesting is an environmentally friendly process that focuses on capturing, harvesting and then recycling as much rainwater as possible for re-use that would otherwise be lost down drains when it rains.

The most obvious example of rainwater harvesting is when one fits a diverter to a surface water drainpipe so that the rainwater run-off is collected in a water butt or other water storage tank, rather than simply being allowed to discharge to the drain.

Limescale, scale and hard water deposits

Limescale, Scale Problems & Hard Water Deposits

The problems caused by limescale, or hard water scale are all too familiar to most of us who live and work in hard water areas.

Limescale is that chalky off-white coating of calcium carbonate that irritatingly builds-up on taps, shower heads, inside kettles and coats the internal surfaces of pipes, boilers, radiators and the like.

Using Chlorine Dioxide to Treat Water, Wastewater & Effluent

Using Chlorine Dioxide to Treat Water, Wastewater & Industrial Effluents

The chemical compound chlorine dioxide has the formula ClO₂, and at room temperature it exists as a yellowish-green gas. It has an odour similar to that of chlorine and is highly soluble in water, being approximately 10 times more soluble than chlorine.

While chlorine dioxide is an oxide of chlorine it is very different from the composition of chlorine itself. It is also occasionally referred to as chlorine (IV) oxide, as one of a number of oxides of the compound.
