Filter Technology

ONEWATER® POE (Point Of Entry)

  • Activated Carbon

The activated carbon utilizes its surface area to bind and contain chemicals. It is most effective at reducing chlorine and other impurities from the water thus removing unpleasant odours.

  • Fine Silica Sand

Fine silica sand is used in the filtration of drinking water, the processing of wastewater, and the production of water from wells. Uniform grain shapes and grain size distributions produce efficient filtration bed operation in removal of contaminants in both potable water and wastewater. Chemically inert, silica will not degrade or react when it comes in contact with acids, contaminants, volatile organics, or solvents.

  • Medium Silica Sand

Filter sand is an extremely effective filter media because of its ability to hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering. Products meet or exceed the NSF/ANSI Standard 61 for Drinking Water System Components, as well as AWWA Standard B100-01.

  • Coarse Silica Sand

The coarse sand acts as support for the other media components and it also increases the exposure time thus enhancing the filter’s effectiveness.

 

ONEWATER® POU (Point Of Use)

Filteration :

I – Pre- Filter (ceramic filter)

Ceramic water filters are an inexpensive and effective type of water filter, that rely on the small pore size of ceramic material to filter dirt, debris, and bacteria out of water.

ii – Sediment (PP 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 a 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.

iii – Pre Carbon

Pre Carbon is commonly used for removing organic constituents and residual disinfectants in water supplies. This not only improves taste and minimizes health hazards; it protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. Activated carbon is a favored water treatment technique because of its multi functional nature and the fact that it adds nothing detrimental to the treated water.

iv – U.F Membrane

Ultra filtration (UF) Membrane is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron. Typically, UF membranes will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules. Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed by UF Membranes. Because only high-molecular weight species are removed, the osmotic pressure differential across the UF Membrane surface is negligible. Low applied pressures are therefore sufficient to achieve high flux rates from an Ultra filtration membrane. Flux of a membrane is defined as the amount of permeate produced per unit area of membrane surface per unit time. Generally flux is expressed as gallons per square foot per day (GFD) or as cubic meters per square meters per day.

 v – Post Carbon

Post carbon  is designed to remove unpleasant taste and odors as well as sediment to produce cleaner, clearer, better tasting water. The Granular Activated Carbon filters are easily installed on the water line to an automatic ice maker, Reverse Osmosis System or water dispensing system.

Activated carbon bonds to thousands of known chemicals. As water is forced through the  carbon, it is forced to slow its flow speed and thereby increase the contact time with the carbon. This slowing of the flow allows the carbon bonding to take place and remove chemical pollutants like toxins, THM’s, chlorine, pesticides, bad tastes, odours, etc.
