Mobile filter press – costs

Mobile filter press Economical application of mobile filter technology

Sludge dewatering is a complex topic in local and industrial wastewater treatment. Not only the composition of sludge - also the economical and plant-engineering boundary conditions diversify heavy. Just through the analysis of the complete situation a ideal solution succeeds. Minimizing of dewatering costs by simultaneous reduction of backlog quantity are definite targets of the users.

In many cases a stationary filter plant is just applicable to a low efficiency factor. Cost-intensive investments often confront to an abstinent capacity.

Mobile MSE filter presses are completely equipped and immediately after connecting of sludge, water and electricity ready for operation. The plants are variable: polymer or calcium carbonate/iron conditioning, according to requirements. In this way you can reach best results for every requirement.

MSE will design and produce the plant for individual customer requests. You will profit from our long standing know-how.

Therefore mobile MSE filter pres plants are suitable to satisfy the technical demands and the economical requirements.

Investment- and operating costs of mobile filter presses

The specific investment costs rise when the procedural plant will be executed smaller. Currently in industrial wastewater treatment plants the actuality bring a economic conflict situation to sludge dewatering. Efficiently and technical outclass dewatering systems like filter presses are engraved through relative high investment costs next to simultaneously low consequential costs e.g. in disposal of the residua. Compared stands a low efficiency of the plant. Therefore stationary dewatering plants are often not orientated on state of technology in practice – expensive operating- and disposal costs will bought with low investment costs!

Kostenrelation mobiler und stationärer FilterpressenanlagenAus dem Sektor kommunaler Kläranlagen ist bekannt, daß eine bestimmte Anzahl dezentraler, stationärer Anlagen generell wesentlich höhere Investitionen verursacht als beispielsweise eine mobile Filterpressenanlage. Die Praxis bestätigt, daß die Relation der Investitionskosten zugunsten mobiler Technologie im Bereich von 1:3 bis 1:15 liegen kann.

On the sector communally clarification plants it’s known that a specific number of local, stationary plants cause generally essential higher investments than e.g. mobile filter presses. The experience confirm that the relation of the investment costs can be between 1:3 – 1:5 in favour of mobile technology.

Similarly rates you can observe on operating costs. Inadequate and inflexible technology, operating stuff with low experience and an abstinent operating profits result in uneconomical high operating- and disposal costs. Therefore mobile plants especially provided- to dewater sludge of several plants in regular intervals but also to compensate surplus capacity and bottlenecks. A very interesting point is that you needn’t any licenses for mobile plants – it´s fast and unbureaucratic!

Technology mobile filter presses

Mobile filter press plants are realisable in different designs. Chamber- or diaphragm filter press, 16 bar or 25 bar operating pressure, with piston diaphragm pump or eccentric screw pump for feeding mounted on a trailer skip or truck trailer according to the dimension limits and the allowed weight under StVZO (Road Traffic Licensing Regulations). The maximum scale of the filter presses are possible till format 1200 with up to 100 chambers (circa 3m³ chamber volume). Smaller plants about format 800 and 1m³ chamber volume are economical realisable.

The conditioning of the sludge predominantly take place with poly-electrolytic flocculation aids (PE). Other methods like calcium carbonate/iron-conditioning, dosing of solid filter aids are occasionally very advantageous in practice. The plants are therefore equipped with suction- and pressure sided inline-mixer. The conditioning parameter, pressure- and/or volume would be controlled proportional via PLC-plant.

The filter press plants are equipped with all necessary equipment like sludge collection container, polymer-conditioning plant, screw conveyor for cake discharge, etc.
For operating of a mobile filter press one user is enough! His function limits on observing and discharging after every charge.
