We know how to build beautifully, reliably, and to last for centuries.

BIOCOMPACT-MULTI

BIOCOMPACT-MULTI is a cyclic activated sludge system for the treatment of industrial and municipal wa tewater.

Is a three-compartment activated sludge reactor with an optimal and cost-effective combination of the two basic process, aeration and sludge settling.

Is combining the advantages of conventional activated sludge process and sequencing batch reactor technology. Like the conventional system, its reactor volume is fixed and the tank level is always constant. Influent flow is continuous and so
is the effluent discharge.

With biological nutrient removal can meet very stringent effluent requirements for BOD, nitrogen and phosphorus.

Consists of three reactors, each reactor is equipped with an aeration system (either surface or fine bubble aeration), whilst the outer reactors are also provided with overflow weirs for effluent dis harge. This means that each of the outer reactors can serve as an aeration and sedimentation tank. Wastewater can be fed into each reactor. Three reactors are hydraulically linked by an opening in the common connecting walls Excess sludge which can be removed from an outlet in each outer reactor.

Can be used for the introduction of enhanced biological nutrient removal. Complex and more concentrated wastewaters or stringent effluent quality requires often treatment in different steps. The multistage.

Configurations offer in this respect the perfect solution.

CSF MODULE

CSF-MODULE is based on the principle of solids contact unit which create convey a larger mass of sludge into the flocculation area. This unit involves the recirculation of sludge.

Is an external recirculation unit based on the lamellae settling principle. It is a fast, compact and adaptable unit, unaffected by variations in raw water composition and flow rate. The unit reduce the volume of settled sludge, which can than be dewatered without further thickening.

Has three main components: flocculator, presettler-thickener, lamella settling. Flocculator provides rapid flocculation with mixing by an axial-flow impeller that recirculates the flow within the reactor and plug-flow conditions prevail to allow slow flocculation. In the Presettler-thickener zone most of the flock settles. The thickened sludge is drawn off through a pipe from the central sludge hopper. Part of the sludge is recirculated to the raw water inlet pipe, thereby ensuring optimum sludge concentration in the reactor at all times. The excess sludge is drained by gravity or pumped away. The sludge is thick enough to be transpo ted to the dewatering system without any additional thickening. Lamellae settling removes the residual flock. The settled water is recovered by a system of collection troughs. The sludge is collected by gravity extracted in and recycled to the head of the reactor.

Effluent at a fairly, constant quality sand filtration was added to this unit. Filtration is brought in to raise the quality of the final effluent and to keep the quality of this effluent as constant as possible.

CFF MODULE

CFF-MODULE system removes pollutants from wastewater through chemical coagulation and flocculation in combination with efficient dissolved air flotation for high rate clarification.

Package is a physical-chemical treatment system. The raw water which may have already undergone chemical flocculation in a flocculator, is injected into a mixed in line where it is placed in contact with air saturated water that has passed through a pressure-release value, resulting in the formation of small air bubbles that attach to the solid particles. Being of lower specific gravity than the water, the particle/bubble composite is separated out in zone and collected at the surface. The resulting sludge is recovered by a surface skimmer and channeled out through a trough. The water separated from the particles is recovered under a scum baffle before it is collected and drained off in. Pressurized water is obtained by recycle pressurization; part of the treated water is recycled and brought into contact with air in a saturation vessel. Solids form bigger flocks settles on the floor which they are discharged by gravity or by means of a special delivery pump. To keep the
