Warning: reading the following will make you start scratching. Head lice, fleas bed bugs - they're all annoying little critters. Here’s the lowdown on those bugs and how to bust em’… Bug enemy Number 1: Head lice • To bust a few myths, these bugs love all hair, even the clean stuff, they don’t necessarily cause itching, so you or your kids might not even know you’ve got them, and the expensive treatments don’t always kill them. • The best way of getting them, according to the bug busting experts at Community Hygiene Concern is to wash hair - they stay still when they’re wet - condition, to help detangle the hair and then comb through it in sections with a specialist comb, checking and removing them. • Break the bug life cycle: They can only move between heads six days after hatching, and can lay eggs seven days after hatching, so it’s vital to get them before then to stop them spreading and reproducing. • More unusual methods of ridding head lice range from tea tree oil, lemon juice, olive oil, hair straighteners and mayonnaise (yes, really).

Bug enemy Number 2: Bed bugs • About the size of an apple pip, this flattened brown fellow is hungry for blood and will feed for up to 15 minutes while you sleep. • They like to travel and will often nestle in clothes, luggage and second hand furniture and they spread fast: the female can lay anything from one to 12 eggs a day. • Once a month, look out for tell-tale blood spots on your bed linen and shed bug skin and faecal traces – black marks. • The only way to get them out is by calling in the professionals. Bug enemy Number 3: Fleas • You’ll be hopping mad if you get them, because unlike bed bugs, fleas normally live outside and are brought into your home on the back of your cat or dog. • They are reddish brown and about 2mm long. Look out for black specks like ground pepper on your pet’s fur, which could be flea poo. • Make sure you vacuum carpets, soft furnishings, curtains and cracks in floorboards to get the bugs and their eggs, then empty the vacuum cleaner.

• Groom your pet regularly with a flea comb, wash their bedding and take them to a vet if they’re scratching. • For major infestations, visit www.rentokil.co.uk.

The free oxygen radical is highly reactive and short lived, under normal conditions it will only Ozone is a colorless gas that has an odor similar to smell of the air after a Ozone has a greater disinfection effectiveness against bacteria and virusesIn addition, the oxidizing properties can also reduce the concentration of iron, manganese, sulfur and reduce or eliminate

taste and odor problems.  Ozone oxides the iron, manganese, and sulfur in the water to form insoluble metal oxides or elemental sulfur.  insoluble particles are then removed by post-filtration.  and chemicals will be eliminated through either coagulation or chemicalOzone is unstable, and it will degrade over a time frame ranging from a few seconds to 30 minutes. degradation is a function of water chemistry, pH and water temperature. The formation of oxygen into ozone occurs with the use of energy. samsung robotic vacuum cleaner sr8950 priceThis process is carried out by an electric dischargelumina rechargeable vacuum cleaner field as in the CD-type ozone generators (corona discharge simulation of the lightning), or by ultraviolet radiation as inmatrex glass vacuum cleaner

UV-type ozone generators (simulation of the ultraviolet rays from the sun). In addition to these commercial methods, ozone may also be made through electrolytic and chemical reactions.  In general, an ozonation system includes passing dry, clean air through a high voltage electric discharge, i.e., corona discharge,  which creates and ozone concentration of approximately 1% or 10,000 mg/L.  In treating small quantities of waste, the UV ozonators are the most common, while large-scale systems use either corona discharge or other bulk The raw water is then passed through a venturi throat which creates a vacuum and pulls the ozone gas into the water or the air is then bubbled up through the water being treated.  Since the ozone will react with metals to create insoluble metal oxides, post filtration is required. 1. Ozone is effect over a wide pH range and rapidly reacts with bacteria, viruses, and protozoans and has stronger germicidal properties then

Has a very strong oxidizing power with a short reaction 2.The treatment process does not add chemicals to the water. 3. Ozone can eliminate a wide variety of inorganic, organic and microbiological problems and taste and odor problems.  agents include bacteria, viruses, and protozons (such as: Giardia and 1. There is a higher equipment and operational cost and it may be more difficult to find professional proficient in ozone treatment and system maintenance. 2. Ozonation provides no germicidal or disinfection residual to inhibit or prevent regrowth. 3. Ozonation by-products are still being evaluated and it is possible that some by-products by be carcinogenic. These may include brominated by-products, aldehydes, ketones, and carboxylic acids.  This is one reason that the post filtration system may include an activate carbon filter. 4.System may require pretreatment for hardness reduction or the additional of polyphosphate to prevent formation of carbonate scale.
