Minicell ®

Dissolved air flotation (DAF) clarifier for small flow applications

 

 

The Minicell is the simplest and the smallest DAF clarifier in the KWI product line. It is designed for small flows.

 

 

 

 

 

 

 

 

Main advantages:

- Simple operation.

- Excellent performance with “difficult” and “ fragile” sludge quality - the sludge blanket does not move and the risk of having “sinking flocs” is negligi le (the sludge is not pushed to the sludge extraction device as the spiral scoop is travelling around the sludge blanket) .

- 3 different tank heights available (choice according to the application).

Main applications:

- Excess biological sludge  clarification  and  thickening  before  further  de-watering   (for small installations) (e xcellent application in case of biological phosphorous removal. This reduce also the polymer consumption in the sludge de-watering system).

- Industrial effluents from the food industry in combination with chemical treatment.

- Industrial low flow effuent.

The tank and the construction of the MINICELL can be adapted to the application and to the effluent.

The depth of the tank varies according to the type of the effluent, the inlet solid concentration and the requirements of the application (clarification with or without chemicals, sludge thickening,...)

MINICELL is available in 10 sizes from 16 to 450 m3/h.

Dissolved air flotation (DAF) clarifier for sludge thickening

Mechanically simple and robust construction combined with sophisticated hydraulic design allows constant and reliable performance in any conditions.     with sophisticated hydraulic design allows constant and reliable performance in any condit          combined      with sophisticated hydraulic design allows constant and reliable performance in any conditions.

 

 

Main advantages:

- High floated sludge consistency is easy to achieve and maintain even without polymer.

- Low sensitivity to variations in flow and quality of the influent.

- Excellent performance with “difficult” and “ fragile” sludge quality The sludge  lanket does  not move and the risk of having “sinking flocs” is negligi le (the sludge is not pushed to the sludge extraction device as the spiral scoop is travelling around the sludge blanket).

Main applications:

- Excess biological sludge thickening before further de-watering (excellent application in case of biological phosphorous removal or for large amounts of excess sludge. This also reduces the polymer consumption in the sludge de-watering system).

- Biological sludge clarification after aeration tanks gives the possibility to raise the concentration in the aeration tanks up to 8-10 g/l.

- The construction of the SEDICELL allows fabrication of the tank in stainless steel or in concrete.

The sludge extraction can be controlled automatically with a sludge blanket controller. This allows fully automatic operation of the entire installation while maintaining optimal operating conditions.

SEDICELL is available in 18 sizes from 2,4 to 20 m diameter.

KS Filter ®

Continuous backwash sand filter.

  Backwash device that allows flexibility and reliability in operation.

 

 

 

 

 

 

 

 

 

 

 

 

Main advantages:

- Gives excellent filtered water quality using double backwash device.

- Simple and maintenance free operation.

- Complete peripheral equipment and accessories allows perfect operational control and fine setting of the backwash.

Main applications:

- Surface water treatment to potable quality.

- Tertiary treatment.

- Process water preparation.

- Process water recycling.

- Algae removal.

The backwash of  the sand is  the most important process parameter for this type of filter.

The sand is taken from the bottom and is pumped by an airlift into the washing chamber. From there it falls back on the top of the sand bed.

The quality of the filtered water depends on the size of the sand and on the sand backwash rate. Therefore the KS FILTER is equipped with a sophisticated and carefully sized double  backwash facility. This design allows a wide variation and fine setting of the backwash parameters.

Eight sizes available: 1,5 to 7 m2 filtration area with 1 or 2 m deep sand filter.

Flotofilter

Dissolved air flotation clarifier and filtration for ground water

Flotofilter was developed based on the KWI experiences collected with the Sandfloat BP and the Klaricell installations.

The new flotofilter implements the same combined clarification filtration technology as the previous circular units, but the design is adapted to rectangular concrete tanks and large flow rates.

 

 

 

 

 

Thanks to an innovative concept, flotofilter performs a two-stage clarification process in one single tank: DAF clarification (ideal to remove SS) + Single or double granular media filtration (achieves excellent filtered water quality) = A combination of 2 complementary water purification technologies!

Main advantages:

  • Economical and compact

- Integrating 5 processes in one machine: coagulation, flocculation, sedimentation, flotation and filtration.

- Small footprint: compared to gravity settling tank plants (old technology widely used in Asia), KWI systems can               be 10 times smaller. Optimizing building space, quantities of pipes, electrical lines makes flotofilter suitable for                 plants with limited space.

- Saving up to 40% of chemicals use, compared to the traditional technology.

- Saving up to 50% of cost for storaging sludge compared to the traditional technology. Flotofiletr ensures, in fact,              higher solids sludge production. Flotofilter, providing clarification in an activated sludge process, will produce a               sludge with a solids content in the 2-5% TS range. Compared to the sludge from a gravity clarifier (0.5-1.5% TS),               the sludge volume generated by flotofilter will typically be 1/4th to 1/10th of the volume generated by a gravity                 clarifier.

- Rate of recovery water up to 100%

  • Reliability

- Treating water with high suspended solids, turbidity and fluctuation of the input water

- A great solution to remove algae and organic, heavy metals as s, Fe, P , Cr…which is not treated by traditional                    technology.

  • Flexibility 

- With a smart sensor system, each unit can operate particularly each process as coagulation, floccutation,                             flotation and filtration or connect them together depending on the composition of input water. This solution can               retrench operating costs for investors

- Sludge from treating backwashed water do not require thickening. They can be leaded into the sludge process

Main applications:

Drinking or industrial water production; first step of clarification of large fresh or sea water flows, including coagulation and flocculation processes. Tertiary treatment for hard COD and phosphorus removal. Flotofilter can treat water from surface water sources.

  • Treating water from well water
  • Very effective in tertiary treatment for removing COD, heavy metals and phosphorus

The common FLOTOFILTER technology combines units to operate continuously and expand module easily
