METHODOLOGY

"Experience you can depend on..."

Over the years the access methods for window cleaning have changed dramatically, as building designs become more complex the methods used to access their windows become more advanced. At Shining Windows, we think your choice is our mission. We will soon be adding the choice of methods to the online shop. Some clients prefer a traditional method being used, others prefer new pure water technology.

Purified water is water that is mechanically filtered or processed to be cleaned for consumption. Distilled water and deionised (DI) water are the most common forms of purified water, but water can also be purified by other processes including reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electro dialysis. In recent decades, a combination of the above processes has come into use to produce water of such high purity that its trace contaminants are measured in parts per billion (PPB) or parts per trillion (PPT) or parts per million (PPM).

 

Purified water has many uses, largely in science and engineering laboratories and industries, and is produced in a range of purities.

We use a 5 stage filteration system to produce pure water
 
Sediment filter

Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid. Sedimentation is the deposition by settling of suspended material. In a water plant, these particles may be rust flakes from the water pipes, sand grains, small pieces of organic matter, clay particles, or any other small particles in the water supply.

 

GAC Filter

A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water.  GAC filters also can be used to remove chemicals that give objectionable odours or tastes to water such as hydrogen sulfide (rotten eggs odour) or chlorine.

 

Carbon Block

Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical absorption.

 

Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for water purification, air purifiers and industrial gas processing, for example, the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane and the recovery of precious metals, especially gold.

 

40-40 Reverse Osmosis

Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential, a thermodynamic parameter. Reverse osmosis can remove many types of molecules and ions from solutions, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.

Mixed bed deionization

Mixed bed deionization is 50/50 mixture of cation and anion resin combined in a single ion exchange column. With proper pre-treatment, product water purified from a single pass through a mixed bed ion exchange column is the purest that can be made by humans. Most commonly, mixed bed de-mineralizers are used for final water polishing to clean the last few ions within the water prior to use. Small mixed bed deionization units have no regeneration capability. Commercial mixed bed deionization units have elaborate internal water and regenerate distribution systems for regeneration. A control system operates pumps and valves for the regenerants of spent anions and cations resins within the ion exchange column. Each is regenerated separately and then remixed during the regeneration process. Because of the high quality of product water achieved, and because of the expense and difficulty of regeneration, mixed bed de-mineralizers are used only when the highest purity water is required.
