A successful DAF Maximizer clarifier pilot study yielding useful data  depends upon equipment that is configured to fit the conditions at  hand. Steps must  be taken to ensure that the raw water flow rate is  uniform, that water temperature, pH and solids loading are controlled,  and that a suitable chemical pretreatment program is provided. If any of  the preceding measures are lacking or deficient,  the pilot study will  likely not be representative of full-scale  operation, thus making it  difficult to project future costs and effluent quality for minimal coast  to the customer. DAF Corp can provide equipment and operators to  make  certain that our DAF technology the pilot clarifier receives wastewater  with uniform  characteristics. This support equipment includes  equalization tanks, coagulation contact tank, oil/water separator,  coagulation-flocculation tube bundle, polymer makeup system and pumps.
 

Note: DAF Clarifier support equipment will vary for different applications for waste water treatment pilot studies.

For the Customer Operation of Cleaning Waste Water:

DAF Corporation offers two types of dissolved air flotation clarifiers, the FC Maximizer and the RC Uni-Max. The FC Maximizer clarifier processes raw water flows of 10 g.p.m. to 8,850 g.p.m. utilizing the   zero velocity concept in a shallow  circular tank. Tank diameters range  from 6 feet to 70 feet. Our RC  UniMax clarifiers are rectangular in  shape and are available in a range  of sizes to process water flows 20  g.p.m. to 1000 g.p.m.  
 

DAF Corp. conducts laboratory DAF feasibility analysis of process waters, provides on-site pilot feasibility studies, design, manufacturing, and complete installations of a DAF clarifier systems. All labor, parts, and equipment supplied by  DAF Corp. are covered by a  one-year warranty.  
 

These clarifiers find applications in pulp and paper mills,  recycled fiber de-inking, food processing, dairy, dairy manure, algae  removal,  textile industries, municipalities, before membrane systems,  and  potable water applications. Our total suspended  solids removal rate can  be below 50 ppm of filterable solids and thickened with a sludge  consistency of 2-4%.
 

The standard DAF FC Maximizer features an all 304L stainless steel round   tank, epoxy painted carbon steel tank bottom supports, side wall stiffeners, heavy duty 304L S/S tank rim, top bridge and catwalks.  Units can be  fabricated entirely of stainless steel  on request. All  clarifiers feature a standard sludge cone, clear  water separation wall,  a micro bubble generator (AMT), center rotary joint, sludge scoop and  top bridge with attached assembly electrical control pre-wired to  clarifier components.
 

Optional DAF Skid-Mounted FC Maximizer clarifiers are very popular. They are preassembled with all ancillary piping, valves, controls, and wiring, ready for operation.  Skid-mounted DAF Maximizer clarifiers  range from 48 g.p.m. (6' diameter) to 200  g.p.m. (10' diameter). 

We recommend a pilot-scale dissolved air flotation system study at  the customer's facility. It is often conducted before a proposal  guarantee stage of a project.  Although we have an extensive database of  DAF process applications from  which to draw, at times it is essential  that pilot trials be conducted on site to appraise the  variability of  the influent and to ensure that the customer's requirements for effluent quality and sludge characteristics are all accountable.
 

DAF Corp. utilizes one six-foot self-contained skid mounted FC-60  Maximizer clarifiers for pilot job site studies. Our FC Maximizer pilot unit operates at influent  flow rates of 10-50 g.p.m. During a  pilot trial, if possible DAF Corp. requests customers:
 

1.  An influent pipe connection, a clarified water pipe connection, a sludge pipe or tank and fresh water for cleanup. Electrical supply -  440/480, 100amp supply.
 

2. All support equipment is available from DAF Corp. if needed, to make  certain that the clarifier receives a consistent flow of properly   pretreated influent. This equipment includes trash pumps,  equalization/pH adjustment tanks, oil/water separators, coagulation tank, influent pumps, tube flocculator bundles, dry/liquid polymer makeup systems, sludge pumps, and storage tanks.
