AQUARIUS ™ : THE PRE - ENGINEERED SOLUTION FOR HIGH SOLIDS LOADING .

THE KEYS TO AQUARIUS®

The Aquarius family of modular and pre-engineered treatment systems combines the conventional treatment steps of flocculation, sedimentation and filtration. The family includes the modular Aquarius, the smaller, factory-assembled Water Boy, and custom systems for higher solids loading. Aquariusplants are among the most compact and efficient water treatment systems ever designed. Three Microfloc technologies – tube settlers, the Mixed Media filter and the Aquaritrol ® III process controller – combine with chemical feeders, influent flow control, flocculation, process valves and an automatic backwash controller to provide a complete and compact treatment system.

COMPLETE , SELF - CONTAINEDTREATMENT

Aquarius and Water Boy plants deliver complete, high-performance water treatment, with no shortcuts. Standardized design and manufacturing procedures reduce cost and size without sacrificing superior treatment process efficiency and quality. The plants can treat water from nearly any source to clarity levels of 0.1 turbidity units and correspondingly low

levels of color, iron andmanganese. Capacities range from 10 gpm to several million gallons per day. The smaller unit, the Water Boy, is available in capacities of 10, 20, 60 and 100 gpm. It is ideally suited for small communities, low-flow industrial applications, resorts and recreation sites.

This 4.75 MGD Aquarius plant is located on the Isle of Wight off the coast of England.

SIMPLE OPERATION

The modularAquarius and Water Boy are uncomplicated plants with excellent performance characteristics. They are designed for constant rate operation, greater reliability and simplification of process controls. All working parts are easily accessible. Flocculator mechanisms with adjustable blades are mounted in the tanks. Sludge is

automatically withdrawn during each backwash without the use of scrapers, andbackwash is initiated on headloss, time or manually using a PLC. Coagulant dosages for Aquarius units are changed automatically using the Aquaritrol III. Both systems are reliable and simple.

TUBE CLARIFICATION : MORE EFFICIENT SOLIDS SEPARATION

Another Microfloc development is the concept of settling tubes. Tube settlers greatly increase the effective clarifier settling area and reducethe distance a particle must fall to strike a settling surface from 10 feet or more to 2 inches. All Aquarius treatment plants include

71/2˚ tubes, which put into practice the theory of shallow depth sedimentation and provide more efficient settleable solids removal. Solids accumulated during operation are flushed from the tubes during each filter backwash.

MIXED MEDIA FILTRATION : HIGHPERFORMANCE FILTRATION TECHNOLOGY

Microfloc Mixed Media filters are a significant advancement in high-rate, high-performance filtration technology. Three or more granular materials of differing size and specific gravity produce a filter that is coarse near the top of the bed and has a progressively finer pore and grain size toward the bottom.Solids removal is spread throughout the Mixed Media filter depth, allowing long, high-rate runs and producing a measurably better effluent quality. The

bottom layer of fine media creates superior quality and breakthrough resistance. All Microfloc water and wastewater filter systems utilize Mixed Media. Additionally, most existing filters can be converted to Mixed Media to increase plant capacitywithout increasing plant size.

MULTIBLOCK ™ UNDERDRAIN

The MULTIBLOCK™ underdrain is a dual lateral design to ensure uniform collection of finished water and even backwash water and air distribution. MULTIBLOCK™ shield retains the Mixed Media without requiring gravel support. All components in contact with the water are constructed of corrosionresistant materials. Once installed, the entire...
