Waste Water Management
Waste Water Treatment
By no means is water purification an easy task. Rather, there are numerous steps involved in the process from removing all foreign matter from water and allowing it to be considered potable. The two main classifications of such treatments are industrial usage and those designed to be implemented around the home.
Treatment of sewage, salt water and other undrinkable run-off waters are generally accomplished in a number of steps. One of the important steps is what is known as reverse osmosis. This technique will allow the water to pass through a semi-permeable membrane; the result being that dissolved substances remain on one side of the membrane and the water is found on the other. However, this process alone is generally not sufficient to produce clean water. Oils and greases are removed by a process of skimming the surface. Solids can be partially removed using the simple process of sedimentation. Organisms in what is known as activated sludge can be used to treat water from a septic tank or raw sewage. Distillation is still another process used to evaporate water from any base materials.
To review, some of the main processes involved with the disposal, filtration and treatment of waste water include:
- Reverse osmosis.
- Water Skimming.
- Activated sludge using the power of microbial organisms to consume waste.
Household Purification Systems
While these processes are indeed very technical in nature, there are several systems that are designed for household use that will prove invaluable to those who may have a poor drinking water quality.
The typical home treatment system utilizes what is known as point-of-use filtration. A typical example of these systems are filters that attach to a tap or those that are used in conjunction with a water pitcher. These designs employ a technique known as granular-activated carbon filters which are generally combined with a mesh overlay. This system can remove many impurities and bad tastes from tap water such as those which are caused by dissolved sediments. Other proven methods are ultra-fine filtration membranes, ceramic filters (the sediment will adhere to the ceramic) and even some kettles contain devices that prevent limescale accumulation.
So, the main types of household purification systems include:
- Carbon filters.
- Ceramic filters.
- Ultra-fine filter membranes.
- Kettles to prevent limescale.
Choosing a Filter
Choosing the right filter is essential to obtain potable and tasty drinking water. Three factors need to be considered. First, only the most well-known brand names should be purchased. This can help prevent any defects in manufacture and inferior quality. Secondly, all such filters should offer at least a three year warranty against any defects. Finally and most importantly, all these items need to be accredited by the American National Standards Institute (or a foreign equivalent). This certification assures the customer that the filter has passed all legal guidelines to be considered safe for home use.
To review, three factors that must be taken into consideration are:
- The quality of the manufacturer.
- A three year warranty or more.
- An accredited ANSI certification.
