With rising crude prices and depleting quality of crude, however, the level of wastewater pollutants in petroleum wastewater is at new high. Such conditions are forcing refineries to use a more advanced water treatment, water recovery methods, and robust processes that work well under a variety of conditions and can handle the changing refinery effluent flow rates. Finally a process that is economical in overall life time cost is needed to make all of this feasible. Aquatech has experience working with these refinery effluent pollutants in the refinery market and offers the advanced petroleum wastewater treatment and recovery technology necessary for the refinery’s needs.

Zero liquid discharge (ZLD) is a wastewater management technique that eliminates liquid waste discharge going outside of operating plants. This has attracted renewed interest worldwide in recent years.
Report on Effluent Treatment Plant (ETP) Operation and Maintenance of Interst...Kowshick Sen
Interstoff Apparels Ltd (IAL) comprises of the latest, most technologically advanced 100% export oriented private limited company with composite knitting, dyeing, finishing and apparel manufacturing plants situated in Chandra, Kaliyakoir, Gazipur, Bangladesh. IAL installed an Effluent Treatment Plant of 75 m3/Hr capacity which is running 24 Hr in a day. By nature, our ETP is Bio-logical with Chemical namely Bio-Chemical plant. This treatment is done by four stages such as preliminary, primary, secondary and tertiary treatment. Waste water comes from mainly dyeing and washing through a trench to equalization tank so for preliminary treatment is done by screening by using net or sieve for removal of large solids such as rags, sticks, grit and grease that may result in damage to equipment or operational problems at different stages of trench.
Kelvin Water Technologies offers complete thermal and non-thermal Zero Liquid Discharge solutions to manage tough-to-treat wastewaters. Kelvin's proprietary evaporators, brine concentrators, and crystallizers can help recover more than 95% of your wastewater while reducing the remaining brine as a product or solid. Kelvin's Siever total organic carbon (TOC) analyzers help control the quality of water to be reclaimed or recycled in semiconductor operations.
When I first started researching into Zero Liquid Discharge (ZLD), I found out that there no compact guides for this process online. This is how the idea for a ZLD booklet was born. This
rough guide is meant to help you understand the basics and to decide what’s best for your Brine Treatment case. Our Team in Lenntech B.V. will be happy to help you out with the details
and to find the best available options that will decrease the cost and increase the efficiency of
your project.

Loading rate is exponentially greater than Granular Activated Carbon (GAC) Captures 50%-140% its weight in pollutants vs3-10% with GAC Saves money of fitrationmedia Won’t leach pollutants back into water or any substrate Unlike carbon sponges, Activated Clay won’t spill pollutants pressed Environmentally friendly Can be restored chemically or biologically and reused repeatedly Also for Industrial, Agricultural and Maritime applications Improves the performance of fuels and working fluids 2
3. Proven product Simple & Reliable Aqua TechnologiesInc cleans Produced Water Filtration, Closed Loop Water and SoilRemediation Systems, physical Spill Containment, flow through Vertical Trench Barriers, and Underwater flow through Contamination Caps. Activated Clay® manufactured by ATI has unique hydrophobic and oiliophilic characteristics that selectively remove hydrocarbons and a range of organic pollutants from aqueous streams down to extremely low levels. This simple product is simple, reliable & economic. Physical process technologies NO CHEMICAL CONSUMPTION Cost far less to operate than conventional chemical injection processes Creates no by-process waste ATI offers an industry leading off-the-shelf systems that can be easily scaled and transported with flows ranging from 50 GPM to 3000 GPM. 3
4. How it works Product Development History In the late 70’s & early 80’s ATI was in the Oil & Gas Exploration, Drilling and Production business. As necessity is the mother of inventions, an accidental spill required them to contain and remove crude oil from water, soil & rocks. Existing approaches were simple, but ineffective: soap, saw dust, fire or absorbent diapers. ATI then saw the industrial need for a material that would adsorb oil only, but not water. Organoclay Sodium bentonite clay, the basic material in drilling mud and kitty litter, is treated physically and chemically to repel water while absorbing hydrocarbons Our unique water treatment product, called ET-1, is a product generally referred to as a polymer modified bentonite or an organoclay. ET-1 is manufactured by binding an amine polymer containing an nitrogen ion onto bentonite clay and drying it in a granular form. 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. 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. 4

6. Produced water is sweet (not salty), but contained trace hydrocarbons
11. 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).
12. 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.5
21. 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. ATI demo kit 6

25. Treated wood products with chemical compounds such as pentachlorophenol (PCP), creosote, chromium and arsenic to soil, groundwater, and sediment.
26. In 1990, the wood treatment operations ceased and early remediation actions were initiated to remove process equipment, piping tanks, and treatment formulations.
27. 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.
