24 Hour Water clean-Up

Water pumping

The pumping of water is a basic and practical technique, far more practical than scooping it up with one's hands or lifting it in a hand-held bucket. This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from an undesirable location. Regardless of the outcome, the energy required to pump water is an extremely demanding component of water consumption. All other processes depend or benefit either from water descending from a higher elevation or some pressurized plumbing Hot Water Extraction (HWE) method, is a method used in chemistry for extraction and for "steam cleaning" (e.g. carpets. as listed by the IICRC to be the primary method for cleaning carpets. Residential, and Commercial). The pressurised hot water extraction (PHWE) process uses a combination of high water pressure for agitation, and hot water to increase reaction rate.

"Steam Cleaning"Though commonly called "Steam Cleaning", no actual steam is involved in the HWE cleaning process, apart from steam that may escape incidentally from hot water. When the cleaning solution comes in contact with the carpet/rug, it is anywhere between 120-250 degrees Fahrenheit, according to the heat available from the cleaning unit. For instance, in a modern truck-mounted carpet cleaning machine, water can be heated to 300+ degrees (F), but after passing through high pressure steel braided hose and several manifolds, the water loses much of its heat.

The typical cleaning method involves a preconditioning of the soiled surface with an alkaline (7 or above on the pH Scale) agent, followed by light agitation with a grooming brush and appropriate dwell time. Next, the surface is passed over several times with a cleaning tool (either manual or automatic) to thoroughly rinse out the preconditioner and, using an acetic acid solution, lower the pH of the fibres to a neutral state. Finally, the surface is dried sufficiently to avoid any possibility of saturation
