AMPAC

As a product development by Amitek, a company specializing internationally in water, waste-water and effluent purifying systems, the Ampac has been designed specifically for sewage treatment. Backed by its network and design and management know-how, Amitek is geared to supply world-class, innovative solutions to customers throughout sub-Saharan Africa and on Indian Ocean Islands

THE AMITEK AMPAC SOLUTION

Ampac Modular Sewage Treatment Plants are compact, configurable, modular waste-water treatment units

Effective Because of their modular design and treatment process, Ampac plants can effectively treat, on an ongoing basis, effluent generated by between 10 and 500 people

Versatile Although modular, each Ampac design and installation is site- specific in accordance with individual customer requirements Its modular and configurable design allows it to be integrated into the most sensitive and trying locations

Durable Ampac plants are manufactured off-site in UV-resistant GRP glass-fibre modules and will last for at least 25 years

Simple Plants are assembled on-site, installed below or above ground level and commissioned quickly and easily Ampac eliminates the need for large civil construction works and on-site labour The Ampac Compac - a smaller model - does not require on-site assembly at all It is constructed off-site and delivered as a built-up unit for quick and easy installation and commissioning

THE AMPAC TREATMENT PROCESS

Ampac uses the tried and tested "Submerged Aeration Media" (SAM) method for treatment This method comprises seven sequential treatment steps and involves:

• solids removal by either a solids collection basket or a screening grid, depending on the model
• an anaerobic settler, followed by
• an anoxic settler and
• an aeration chamber into which air is blown to supply the required volume of oxygen Special media sheets are suspended above the air spargers for the growth and retention of aerobic bacteria to continue the digestion of organic material in the effluent
• the settler, in which micro-organisms and any remaining inorganic material is settled out and returned to the primary anaerobic settler by a unique efficient venturi method
• an extended anoxic chamber after the settler that assists in the removal of nitrates
• a disinfection chamber that uses either chlorine, ozone or ultra-violet light to destroy any remaining micro-organisms or pathogens

AMPAC IN ACTION

Ampac units are ideal as plants for the treatment of domestic sewage in the event of projects that do not have a formal municipal sewer connection Compact, simple and robust, Ampac plants use the highly efficient submerged aeration media method to purify effluent through various interlinked stages This provides optimised nitrification and a

treated effluent quality that meets the requirements of the Department of Water Affairs (DWA) for the release of such treated effluent back into the environment under the General Limit Values, in terms of Section 39 of the National Water Act

Designed and constructed to provide the most practical solution:

• The design is based on sound, tried and tested technologies
• Ampac plants are single compact units with no tanks and gaps to gather dirt or rubbish
• Plants are easy to pack into shipping containers for assembly anywhere, even at remote sites
• An easy-to-clean solids strainer allows easy removal of plastic bags, cloths, etc
• Proper aeration is provided by robust nopon fine-bubble spargers and side-channel blowers
• A duty and standby blower ensures continuous safe operation by ensuring adequate oxygen and returning sludge
• There are no pumps between chambers that can cause blockages and stoppages
• The ingenious design makes plant overflows impossible
• Irregular flows into the plant will not upset its functioning
• Ampac is easy to de-sludge and maintain
• Flow meters constantly measure flow-through

CIVIL CONSTRUCTION AND HOUSING OF AMPAC UNITS

All the inter-leading chambers of Ampac units are housed in an Amtank that is constructed in UV- and moisture-resistant GRP glass-fibre panels that are hot-press moulded and comply with BS 7491 part 3

Units are manufactured off-site and assembled on-site, using approved hot-dip galvanised steel parts on the outside and stainless steel fasteners on the inside, and sealed internally with a Plexus epoxy specifically designed for use in sewage treatment plants The structure is supported and stabilised internally by means of chamber partitions, a series of connecting tensile stainless steel rods and attachments and PVC vertical support columns Furthermore, Ampac units are assembled on a smooth, level concrete slab, making it easy and quick to install them on site.
