Industrial wastewater treatment: succeeding with ACWA
15 October 2010, News release from ACWA Services
Industrial wastewater disposal is a formidable challenge for companies battling to keep costs down, meet ever-stricter and more complex legislative requirements and treat increased flows and loadings.
Choosing a partner that can provide carefully-tailored, cost-effective and optimised treatment solutions gives the advantage companies need to survive in today's demanding market.
ACWA Services has almost 25 years' experience in design, installation, commissioning and operation of wastewater treatment plants for the industrial sector. Its expertise can enable sites to achieve the difficult balance of minimising energy and disposal costs while complying fully with legislation.
The company has undertaken projects across a wide range of industrial sectors, including the food, consumer goods, chemicals, motor and waste industries, gaining in-depth knowledge of the entire spectrum of treatment possibilities and combinations.
ACWA presents impartial advice about the best process for each individual site, employing its expertise in providing both conventional and advanced technologies. The company can design, supply and install the appropriate preliminary and primary treatment, secondary settlement, final clarification and tertiary treatment processes as required.
Preliminary processes offered by ACWA include coarse and fine screening systems, grit removal, balancing and calamity systems, pH correction systems, nutrient addition and polymer systems.
ACWA is able to provide a comprehensive range of primary treatment systems, including conventional settlement systems, bio-filters, lamella separators, and dissolved air flotation (DAF) systems. The company can also supply fat, oil and grease removal systems.
ACWA's aerobic treatment plants vary in complexity from simple partial treatment systems to multi-stage plants to treat a wide range of effluent types, including unusual or challenging wastewaters. The company can offer conventional secondary biofilters, low and high rate biotowers, activated sludge processes using coarse or fine bubble diffused air or pure oxygen, Sequencing Batch Reactors (SBRs), Membrane Bioreactors (MBRs), nutrient removal systems and high-rate ammonia removal systems (Amtreat®).
In order to meet the most demanding of discharge standards ACWA can provide a comprehensive range of tertiary treatment processes including continuous upflow, rapid gravity and moving bed sand filters and nutrient removal systems.
ACWA also has experience in providing quaternary systems that produce an effluent quality suitable for re-use in irrigation, process waters or washwaters. These systems include disinfection processes, for example chlorination and granular activated carbon (GAC) systems, micro- and ultra-filtration, reverse osmosis and ozonation.
For incinerator waste liquors, the company has extensive experience in designing, installing and commissioning Scrubber Effluent Treatment (SET) plants, which can remove contaminants, such as mercury, heavy metals, and inert solid particles from industrial liquid streams to meet the Waste Incineration Directive EC2000/76 requirements for discharge to a wastewater treatment facility or direct to watercourse.
ACWA Services Proposals Manager, Gary Harris says: "ACWA's considerable industrial wastewater treatment capabilities provide clients with the reassurance they need that even in a difficult market climate where costs must be driven down, they will still be able to meet all the legislative responsibilities that they bear. Cost-effective, optimised systems are the only way forward."
