Modular Technology
Klean Water provides versatile, customized, modular systems producing the highest quality of water purification, without the use of chemicals, in the shortest delivery time possible.
Our innovative technology utilizes a proprietary seven-module water purification process that is built within a patented anti-shock frame, which is enclosed in a patented climate controlled reefer container.
The main component that sets us apart from the competition is our ceramic membrane, coupled with our ozone back-flush technology. Other notable features of our solution include:
- Trailer mounted designs for mobility & reuse at other well sites
- Totally automated processes with remote computer monitoring
- Low maintenance & operating costs
- Ultra low energy use
- Meets or exceeds water quality standards for:
- Sodium adsorption ratio (SAR)
- Electrocoagulation (EC)
- pH
- Total Dissolved Solids (TDS) and Whole Effluent Toxicity (WET) testing
- Lowest cost turnkey solutions
- Reliable & cost effective
- Adaptable to varying water conditions.
Below are the main technology components and the purpose they serve in our modular filtration system:
Modules
Air supply: Produces high quality oxygen from ambient air.
Ozone: Oxidation of organic and inorganic matter.
Ultraviolet (UV) System: Works as catalyzer in the oxidation process.
Retention Tanks: Ensures optimum ozone reaction time.
Back Flush: Automated cleaning of ceramic filter.
Active Carbon: Completes the oxidizing cycle.
Pre-Filtration: Prevents carbon residue downstream.
Reverse Osmosis: Pressurized flow of different solute concentrations across a membrane.
Re-hardener: Adding minerals for drinking water purposes.
Technology Components
Pure Oxygen Generator
Can be used in further processing or to increase the oxygen content in the water.
Ozone Generator
Common use of ozone:
- Disinfection
- Color removal – break-up of humus molecules
- Oxidation of inorganic compounds (E.g. Fe2+ and Mn2+)
- Oxidation of organic compounds, as odor/taste, algal toxins and organic environmental poisons
- Taste improvement – oxidation
- Removal of pesticides and pharmaceuticals
Advanced Oxidation Process
The Advanced Oxidation Process (AOP) process oxidizes dissolved inorganic matter, or soluble ions. The oxidation process will turn iron and manganese and other metal irons into a filterable form. Ozone is a powerful oxidant that preferentially oxidizes the electron rich functional group of a molecule containing carbon–carbon double bonds and aromatic alcohols. It oxidizes the naturally occurring organic matter (NOM). This technology is also capable to oxidize the most resistant pharmaceutical compound.
Oxidation before the filtering process has proven to reduce membrane fouling of the ceramic filters. The combination of advanced oxidation and ceramic membrane with catalytic coating is one of our new and most promising technologies.
Micro Filtration
We use a self-cleaning micro filter that will remove particles larger than 50 -200 micron depending on the influent. This filter only removes larger particles as clay, inorganic oxides.
Ceramic Membrane Ultra Filtration
After the pre-treatment of the water, the ceramic membrane module works as a very robust ultra filtration system with a minimum risk of fouling. The flux will constantly be optimized to give the lowest possible pressure drop in order to optimize the energy consumption. An advanced in-line cleaning system controls the fouling. The built in cleaning system consists of a high-speed back pulse system. Ceramic membranes are chemically resistant for the full pH value from 1-14
Ultrafiltration is used to remove all suspended particles (bacteria, parasites, viruses, organic molecules and colloids) during raw water treatment or the production of process water for cooling, boiler and manufacturing systems. We utilize ceramic membrane technology in the following solutions:
- Treat water containing oil emulsion
- Remove oil & TSS regardless of particle size – the system is not affected by heavy crude oil with gravity closer to water
- Treat water with oil content of up to 100.000 ppm (output TDS < 10 ppm, mostly 1 ppm when testing)
- 1 step solution to replace Skimming tank, Micro flotation and Walnut shell filter
Nano-Filtration & Reverse Osmosis Membrane Filtration
The Nano-filtration (NF) systems treat low salinity brackish or surface water. The Nano filtration system configuration and economics is similar to the brackish Reverse Osmosis (RO) systems. The objective of Nano-filtration systems is to reduce concentration of specific components from the feed water, usually hardness, iron, organics or color while allowing monovalent ions to pass through. Some of the Nano-filtration systems operate mainly for removal of low concentration of pesticides that are sometimes present in potable water at specific locations. Due to low salinity, low rejection and high permeability of Nano-filtration membranes, the NF systems operate at low feed pressure, usually below 10 bar.
The brackish RO membrane systems treat low and medium salinity fed water from 5-15.000ppm TDS and operate at a feed pressure range of 10 – 25 bar. The recovery rate is in the range of 75% – 85%. The recovery-limiting factor is mainly a concentration of sparingly soluble salts, mainly silica and CaSO4.
The seawater RO membrane systems treat salinity fed water from 15-40.000ppm TDS and operate at a feed pressure range of 30-80 bar.
Rainwater collected from storm drains is purified with reverse osmosis water processors and used for landscape irrigation and industrial cooling as a solution to the problem of water shortages. Reverse Osmosis is used in multiple industries to remove the minerals from boiler water, produce deionized water, and clean the effluent from process water streams. RO processes do not require thermal energy and are regulated with high-pressure pumps. The recovery of purified water depends upon various factors including membrane size, pore size, water temperature, operating pressure and membrane surface area.
Granular Active Carbon (GAC)
Granular activated carbon filtering utilizes a form of activated carbon with a high surface area, and absorbs many compounds, including toxic compounds. Water passing through activated carbon is commonly used in connection with hand pumped filters to address organic contamination, taste, or objectionable odors. Activated carbon filters aren’t usually used as the primary purification technique of potable water purification devices, but rather as secondary means to complement another purification technique. GAC is more commonly used as an ore-filter or post-filter along with other treatment steps. Activated charcoal can remove chlorine from treated water, removing any residual protection remaining in the water. For this reason it should not be used after chemical disinfection treatments in potable water purification processing.
Re-mineralization & pH Adjustment
The water purified by NF and RO membranes is very corrosive and is “stabilized” to protect downstream pipelines and storage, usually by adding Calcium and Magnesium. Liming material is used to adjust pH between 6.8 and 8.1 to meet the potable water specifications, primarily for effective disinfection and for corrosion control.
Ion Exchange System
This technology can be used in the following water treatment applications:
- To soften the feed water to meet requirements for boiler feed water
- Production of ultra-pure water or de mineralized water
- Ion-specific treatment.
