How it works<br />Product Development<br />History<br />In the late 70’s & early 80’s ATI was in the Oil & Gas Exploration, Drilling and Production business.<br />As necessity is the mother of inventions, an accidental spill required them to contain and remove crude oil from water, soil & rocks.<br />Existing approaches were simple, but ineffective: soap, saw dust, fire or absorbent diapers.<br />ATI then saw the industrial need for a material that would adsorb oil only, but not water.<br />Organoclay<br />Sodium bentonite clay, the basic material in drilling mud and kitty litter, is treated physically and chemically to repel water while absorbing hydrocarbons<br />Our unique water treatment product, called ET-1, is a product generally referred to as a polymer modified bentonite or an organoclay. <br />ET-1 is manufactured by binding an amine polymer containing an nitrogen ion onto bentonite clay and drying it in a granular form. <br />More specifically, the nitrogen end of the quaternary amine, the hydrophilic end, is positively charged, and ion exchanges onto the clay platelet for sodium or calcium. The amines used are of the long chain type with 12-18 carbon atoms. After some 30 per cent of the clay surface is coated with these amines it becomes hydrophobic and, with certain amines, organophilic.<br />The polymer binds to the bentonite's ionic surfaces and converts the clay from a hydratable form to an oil-wet, hydrocarbon adsorbent material ideal for water treatment applications.<br />4<br />
Water Treatment with Activated Clay alone<br />Cleans produced water<br /><ul><li>Produced water from natural gas field
Produced water is sweet (not salty), but contained trace hydrocarbons
Petroleum dispersed into droplets too small to separate with existing equipment
Production chemicals including foamers and methanol that affect interfacial tension
Low water salinity interfered with the coalescing of droplets
Cleaned produced water so it can be discharged at surface (10mg/L)
Since enhanced separation equipment, such as hydrocyclones and centrifuges, had not been adopted in the Rocky Mountains, adsorption alone was used to remove free and dispersed hydrocarbons to below discharge limits (10 mg/L).
ET-1 organoclay successfully removed these components, while activated carbon removed the bulk of the dissolved contaminants. The installation also handled the expected system upsets and even trapped an accidental truckload of invert-emulsion drilling fluid.</li></ul>5<br />
Water Treatment: Ionizer + Activated Clay<br />Cleans water to drinking standard<br /><ul><li>In-field solution, no trucking
Ionizer breaks emulsions and drops solids from suspension
Activated Clay absorbs 50%+ its weight in pollutants versus activated carbon (3-10%)
Reverse-osmosis (RO) unit can be added for salty or brackish water
Cleans produced water so it can be discharged at surface
Units can be designed to achieve drinking water standards
Aqua Technologies Inc (ATI) has supplied Activated Clay since 1999
Currently thousands of pounds of Activated Clay clean millions of gallons of process water daily. ATI’s clients in the US and abroad range from refineries and major O&G companies to manufacturers and remediation projects. </li></ul>ATI demo kit<br />6<br />

Covers ~58 acres of terrestrial and aquatic land on the east bank of the Willamette River in Portland, Oregon.
Home of McCormick & Baxter company from early-1940s to 1990
Treated wood products with chemical compounds such as pentachlorophenol (PCP), creosote, chromium and arsenic to soil, groundwater, and sediment.
In 1990, the wood treatment operations ceased and early remediation actions were initiated to remove process equipment, piping tanks, and treatment formulations.
In July of 2004 the 25 acres of the Willamette River bed and adjacent shore were covered by articulated concrete block over a layer of over 1.2 million pounds of ET-1 Activated Clay.

Specific installations may permit a substantially higher flow rates.
Residence time is based on an intragranular porosity of 34-39%.
New installations take advantage of upflow adsorption,
Existing containers designed for granular activated carbon usually work with ET-1 without modification.</li></ul>9<br />Activated Clay®<br />
